    The effects of indexing strategy-query term combination on retrieval effectiveness in a Swedish full text database2004Doktoravhandling, monografi (Annet vitenskapelig)
    Abstract [en]

    This thesis deals with Swedish full text retrieval and the problem of morphological variation of query terms in thedocument database. The study is an information retrieval experiment with a test collection. While no Swedish testcollection was available, such a collection was constructed. It consists of a document database containing 161,336news articles, and 52 topics with four-graded (0, 1, 2, 3) relevance assessments.

    The effects of indexing strategy-query term combination on retrieval effectiveness were studied. Three of five testedmethods involved indexing strategies that used conflation, in the form of normalization. Further, two of these threecombinations used indexing strategies that employed compound splitting. Normalization and compound splittingwere performed by SWETWOL, a morphological analyzer for the Swedish language. A fourth combinationattempted to group related terms by right hand truncation of query terms. A search expert performed the truncation.The four combinations were compared to each other and to a baseline combination, where no attempt was made tocounteract the problem of morphological variation of query terms in the document database.

    Two situations were examined in the evaluation: the binary relevance situation and the multiple degree relevancesituation. With regard to the binary relevance situation, where the three (positive) relevance degrees (1, 2, 3) weremerged into one, and where precision was used as evaluation measure, the four alternative combinationsoutperformed the baseline. The best performing combination was the combination that used truncation. Thiscombination performed better than or equal to a median precision value for 41 of the 52 topics. One reason for therelatively good performance of the truncation combination was the capacity of its queries to retrieve different partsof speech.

    In the multiple degree relevance situation, where the three (positive) relevance degrees were retained, retrievaleffectiveness was taken to be the accumulated gain the user receives by examining the retrieval result up to givenpositions. The evaluation measure used was nDCG (normalized cumulated gain with discount). This measurecredits retrieval methods that (1) rank highly relevant documents higher than less relevant ones, and (2) rankrelevant (of any degree) documents high. With respect to (2), nDCG involves a discount component: a discount withregard to the relevance score of a relevant (of any degree) document is performed, and this discount is greater andgreater, the higher position the document has in the ranked list of retrieved documents.

    In the multiple degree relevance situation, the five combinations were evaluated under four different user scenarios,where each scenario simulated a certain user type. Again, the four alternative combinations outperformed thebaseline, for each user scenario. The truncation combination had the best performance under each user scenario.This outcome agreed with the performance result in the binary relevance situation. However, there were alsodifferences between the two relevance situations. For 25 percent of the topics and with regard to one of the four userscenarios, the set of best performing combinations in the binary relevance situation was disjunct from the set of bestperforming combinations in the multiple degree relevance situation. The user scenario in question was such thatalmost all importance was placed on highly relevant documents, and the discount was sharp.

    The main conclusion of the thesis is that normalization and right hand truncation (performed by a search expert)enhanced retrieval effectiveness in comparison to the baseline, irrespective of which of the two relevance situationswe consider. Further, the three indexing strategy-query term combinations based on normalization were almost asgood as the combination that involves truncation. This holds for both relevance situations.

    Exploring the relation between referencing practices and citation impact: A large-scale study based on Web of Science data2018Inngår i: Journal of the Association for Information Science and Technology, ISSN 2330-1635, E-ISSN 2330-1643, Vol. 69, nr 5, s. 728-743Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    In this large-scale contribution, we deal with the relationship between properties of cited references of Web of Science articles and the field normalized citation rate of these articles. Using nearly 1 million articles, and three classification systems with different levels of granularity, we study the effects of number of cited references, share of references covered by Web of Science, mean age of references and mean citation rate of references on field normalized citation rate. To expose the relationship between the predictor variables and the response variable, we use quantile regression. We found that a higher number of references, a higher share of references to publications within Web of Science and references to more recent publications correlate with citation impact. A correlation was observed even when normalization was done with a finely grained classification system. The predictor variables affected citation impact to a larger extent at higher quantile levels. Regarding the relative importance of the predictor variables, citation impact of the cited references was in general the least important variable. Number of cited references carried most of the importance for both low and medium quantile levels, but this importance was lessened at the highest considered level.

    Field normalized citation rates, field normalized journal impact and Norwegian weights for allocation of university research funds2012Inngår i: Scientometrics, ISSN 0138-9130, E-ISSN 1588-2861, Vol. 92, nr 3, s. 767-780Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    We compared three different bibliometric evaluation approaches: two citation-based approaches and one based on manual classification of publishing channels into quality levels. Publication data for two universities was used, and we worked with two levels of analysis: article and department. For the article level, we investigated the predictive power of field normalized citation rates and field normalized journal impact with respect to journal level. The results for the article level show that evaluation of journals based on citation impact correlate rather well with manual classification of journals into quality levels. However, the prediction from field normalized citation rates to journal level was only marginally better than random guessing. At the department level, we studied three different indicators in the context of research fund allocation within universities and the extent to which the three indicators produce different distributions of research funds. It turned out that the three distributions of relative indicator values were very similar, which in turn yields that the corresponding distributions of hypothetical research funds would be very similar.

    Research collaboration between Stockholm University and other Swedish academic institutions: a bibliometric study to support decisions on library collaboration2015Inngår i: Qualitative and Quantitative Methods in Libraries (QQML), ISSN 2241-1925, Vol. 4, s. 49-60Artikkel i tidsskrift (Annet vitenskapelig)
    Abstract [en]

    Academic libraries collaborate in several ways. For instance, collaboration can concern standards for indexing and statistics, technical solutions or collection development. A question that a given academic library might ask is with which other academic libraries the library should principally collaborate. In this study, we show how bibliometric methods can be used to generate information that can support decision making with regard to the question at stake. We evaluate the amount of research collaboration between Stockholm University and other Swedish academic institutions across five publishing years, and for the whole considered time period, where research collaboration is operationalized as co-publishing. A dataset of publications obtained from Web of Science, where each publication has at least one Stockholm University address, is used in the study. Co-publishing rates, non-fractionalized and fractionalized, across the publishing years and for the whole for period, for Stockholm University and other Swedish academic institutions, are reported. Further, parts of the outcome of the study are visualized in terms of co-publishing networks.

    Requirements for a cocitation similarity measure, with special reference to Pearson's correlation coefficient2003Inngår i: Journal of The American Society For Information Science And Technology, ISSN 1532-2882, E-ISSN 1532-2890, Vol. 54, nr 6, s. 550-560Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Author cocitation analysis (ACA), a special type of cocitation analysis, was introduced by White and Griffith in 1981. This technique is used to analyze the intellectual structure of a given scientific field. In 1990, McCain published a technical overview that has been largely adopted as a standard. Here, McCain notes that Pearson's correlation coefficient (Pearson's r) is often used as a similarity measure in ACA and presents some advantages of its use. The present article criticizes the use of Pearson's r in ACA and sets forth two natural requirements that a similarity measure applied in ACA should satisfy. It is shown that Pearson's r does not satisfy these requirements. Real and hypothetical data are used in order to obtain counterexamples to both requirements. It is concluded that Pearson's r is probably not an optimal choice of a similarity measure in ACA. Still, further empirical research is needed to show if, and in that case to what extent, the use of similarity measures in ACA that fulfill these requirements would lead to objectively better results in full-scale studies. Further, problems related to incomplete cocitation matrices are discussed.

    Measuring impact of twelve information scientists using the DCI index2010Inngår i: Journal of The American Society For Information Science And Technology, ISSN 1532-2882, E-ISSN 1532-2890, Vol. 61, nr 7, s. 1424-1439Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    The Discounted Cumulated Impact (DCI) index has recently been proposed for research evaluation. In the present work an earlier dataset by Cronin and Meho (2007) is reanalyzed, with the aim of exemplifying the salient features of the DCI index. We apply the index on, and compare our results to, the outcomes of the Cronin-Meho (2007) study. Both authors and their top publications are used as units of analysis, which suggests that, by adjusting the parameters of evaluation according to the needs of research evaluation, the DCI index delivers data on an author's (or publication's) "lifetime" impact or current impact at the time of evaluation on an author's (or publication's) capability of inviting citations from highly cited later publications as an indication of impact, and on the relative impact across a set of authors (or publications) over their "lifetime" or currently.

    Abstract [en]

    In this paper, which treats Swedish full text retrieval, the problem of morphological variation of query terms in the document database is studied. The Swedish CLEF 2003 test collection was used, and the effects of combination of indexing strategies with query terms on retrieval effectiveness were studied. Four of the seven tested combinations involved indexing strategies that used normalization, a form of conflation. All of these four combinations employed compound splitting, both during indexing and at query phase. SWETWOL, a morphological analyzer for the Swedish language, was used for normalization and compound splitting. A fifth combination used stemming, while a sixth attempted to group related terms by right hand truncation of query terms. The truncation was performed by a search expert. These six combinations were compared to each other and to a baseline combination, where no attempt was made to counteract the problem of morphological variation of query terms in the document database. Both the truncation combination, the four combinations based on normalization and the stemming combination outperformed the baseline. Truncation had the best performance. The main conclusion of the paper is that truncation, normalization and stemming enhanced retrieval effectiveness in comparison to the baseline. Further, normalization and stemming were not far below truncation.

    Bibliometric analysis of two subdomains in philosophy: free will and sorites2015Inngår i: SCIENTOMETRICS, ISSN 0138-9130, Vol. 103, nr 1, s. 47-73Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    In this study we tested the fruitfulness of advanced bibliometric methods for mapping subdomains in philosophy. The development of the number of publications on free will and sorites, the two subdomains treated in the study, over time was studied. We applied the cocitation approach to map the most cited publications, authors and journals, and we mapped frequently occurring terms, using a term co-occurrence approach. Both subdomains show a strong increase of publications in Web of Science. When we decomposed the publications by faculty, we could see an increase of free will publications also in social sciences, medicine and natural sciences. The multidisciplinary character of free will research was reflected in the cocitation analysis and in the term co-occurrence analysis: we found clusters/groups of cocited publications, authors and journals, and of co-occurring terms, representing philosophy as well as non-philosophical fields, such as neuroscience and physics. The corresponding analyses of sorites publications displayed a structure consisting of research themes rather than fields. All in all, both philosophers involved in this study acknowledge the validity of the various networks presented. Bibliometric mapping appears to provide an interesting tool for describing the cognitive orientation of a research field, not only in the natural and life sciences but also in philosophy, which this study shows.

    The correlation between citation-based and expert-based assessments of publication channels: SNIP and SJR vs. Norwegian quality assessments2014Inngår i: Journal of Informetrics, ISSN 1751-1577, E-ISSN 1875-5879, Vol. 8, nr 4, s. 985-996Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    We study the correlation between citation-based and expert-based assessments of journals and series, which we collectively refer to as sources. The source normalized impact per paper (SNIP), the Scimago Journal Rank 2 (SJR2) and the raw impact per paper (RIP) indicators are used to assess sources based on their citations, while the Norwegian model is used to obtain expert-based source assessments. We first analyze – within different subject area categories and across such categories – the degree to which RIP, SNIP and SJR2 values correlate with the quality levels in the Norwegian model. We find that sources at higher quality levels on average have substantially higher RIP, SNIP, and SJR2 values. Regarding subject area categories, SNIP seems to perform substantially better than SJR2 from the field normalization point of view. We then compare the ability of RIP, SNIP and SJR2 to predict whether a source is classified at the highest quality level in the Norwegian model or not. SNIP and SJR2 turn out to give more accurate predictions than RIP, which provides evidence that normalizing for differences in citation practices between scientific fields indeed improves the accuracy of citation indicators.

    The role of the Chinese Key Labs in the international and national scientific arena revisited2017Inngår i: Research Evaluation, ISSN 0958-2029, E-ISSN 1471-5449, Vol. 26, nr 2, s. 132-143Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    In this contribution, which builds on and develops a study that was published more than 10 years ago, we address the role of the Chinese Key Labs (KLs) in the international and national scientific arena. We give a short overview of the position of KLs in China, including their budget and manpower. Based on large numbers of Chinese publications obtained from the Web of Science (WoS) and the Chinese Science Citation Database (CSCD), the KLs are compared across publication years to the rest of China (ChRest) with respect to publication output and citation impact. We also look at collaboration in terms of co-publishing between the KLs and the ChRest. As to publications in the WoS, we found that the contribution of KLs compared with the ChRest is slightly and irregularly increasing (using full counting as well as fractional counting), whereas a stronger increasing trend is observed for the corresponding contribution in the CSCD. We observed an increase in the number of collaborations between KLs and Chinese colleagues, regardless of database. For WoS and field normalized citation indicators, we obtained the expected results that researchers at KLs perform considerably better than other Chinese colleagues and, moreover, perform clearly better than database average. As such we may conclude that KLs have lived up to their promise and made real impact on the international arena.

    Twenty-five years and counting: an analysis of the Journal of Strategic Marketing2018Inngår i: Journal of Strategic Marketing, ISSN 0965-254X, E-ISSN 1466-4488, Vol. 26, nr 2, s. 125-139Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    This article presents a content analysis of the Journal of Strategic Marketing (JSM) over 24 years from the journal's inception in 1993 to 2017. No similar attempt on an analysis of JSM has been found. Analyses were completed to examine how the journal has developed and to uncover relevant information for editors, reviewers, researchers and future authors of JSM by analysing research themes, author and manuscript characteristics, and citation metrics. The findings reveal an increase in multi-authored articles, an increase in empirical research and in the internationalization of researchers. These and other factors illuminate sources and implications of the journal's current state. The relevance of these findings is discussed as it pertains to the future success and publishing opportunities in the Journal of Strategic Marketing.

    Knowledge production at industrial research institutes: Institutional logics and struggles for relevance in the Swedish Institute for Surface Chemistry, 1980-20052017Inngår i: Research Evaluation, ISSN 0958-2029, E-ISSN 1471-5449, Vol. 26, nr 4, s. 337-348Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    This article examines dynamics of knowledge production and discourses of basic-applied science and relevance at the Swedish Institute for Surface Chemistry, a semi-public industrially oriented research institute, from 1980 to 2005. We employ a three-pronged method, consisting of (1) an analysis of how the institute articulated its research priorities and goals in publications primarily directed to stakeholders, (2) an analysis of retrospective narratives by researchers and managers about research ideologies and priorities, and (3) a bibliometric analysis of the institute's scientific publications. Using a theoretical framework centered on the notions of institutional logics and struggles for relevance, we show how the transformations of the institute amount to a substitution of an internalized institutional logic of scientific autonomy with a new logic of industrial utility, and how the institute's knowledge production was managed during this change. We also point out various strategies used by the institute to preserve and advance its own goals while still remaining relevant with regard to changing policy objectives. Another important finding is that although the institute by the end of the study period was fully committed to an industrial service role, parts of the originally deeply entrenched scientific logic were still manifested, although then discussed in the new industrial terminology.

    Comparison of publication-level approaches to ex-post citation normalization2019Inngår i: Scientometrics, ISSN 0138-9130, E-ISSN 1588-2861, Vol. 120, nr 1, s. 283-300Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    In this paper, we compare two sophisticated publication-level approaches to ex-post citation normalization: an item-oriented approach and an approach falling under the general algorithmically constructed classification system approach. Using articles published in core journals in Web of Science (SCIE, SSCI & A&HCI) during 2009 (n=955,639), we first examine, using the measure Proportion explained variation (PEV), to what extent the publication-level approaches can explain and correct for variation in the citation distribution that stems from subject matter heterogeneity. We then, for the subset of articles from life science and biomedicine (n=456,045), gauge the fairness of the normalization approaches with respect to their ability to identify highly cited articles when subject area is factored out. This is done by utilizing information from publication-level MeSH classifications to create high quality subject matter baselines and by using the measure Deviations from expectations (DE). The results show that the item-oriented approach had the best performance regarding PEV. For DE, only the most fine-grained clustering solution could compete with the item-oriented approach. However, the item-oriented approach performed better when cited references were heavily weighted in the similarity calculations.

    Disciplinary structures in Nature, Science and PNAS: journal and country levels2018Inngår i: Scientometrics, ISSN 0138-9130, E-ISSN 1588-2861, Vol. 116, nr 3, s. 1817-1852Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    This paper analyzes, using Web of Science publications and two time periods (2004-2006 and 2014-2016), the disciplinary structures in the three prestigious journals Nature, Science and PNAS, compared with two baselines: Non-NSP_Multi (multidisciplinary publications that have other source journals than Nature, Science and PNAS), and Non-Multi (publications assigned to other categories than Multidisciplinary). We analyze the profiles at two levels, journal and country. The results for the journal level show that for Nature and Science, the publications are considerably less concentrated to certain disciplines compared to PNAS. Biology is the dominant discipline for all the three journals. Nature and Science have similar publication shares in Medicine, Geosciences, Physics, Space science, and Chemistry. The publications of PNAS are highly concentrated to two disciplines: Biology and Medicine. Compared with Non-NSP_Multi and Non-Multi, the shares of Biology in NSP journals are higher, whereas the share of Medicine is lower. At the country level, 14 countries are included, among them the five BRICS countries. With respect to the NSP journals, the emphasis disciplines (in terms of world share of publications) of most countries other than USA are the disciplines in which USA has its weakest performance. The disciplinary structures of USA and of most of the other studied countries therefore tend to be different. Regarding Non-NSP_Multi and Non-Multi, the shapes of the disciplinary structures of the 14 countries can be roughly grouped into three groups, while there are more types of shapes for the countries in the NSP journals. For all five units of analysis, the discipline structures of most countries generally change only slightly between different time periods. The structures of some BRICS countries, however, change to a relatively large extent.

    Open Access-publicering vid svenska lärosäten : en kartläggning av året 20112014Rapport (Annet vitenskapelig)
    Abstract [sv]

    Syftet med projektet har varit att undersöka hur stor del av den svenska forskningen som har publicerats open access under publiceringsåret 2011. Vi har studerat den totala andelen open access-publikationer, både så kallad guld och grön open access, dels nationellt och dels per lärosäte. Vi har också velat undersöka hur stor andel av artiklarna i vårt underlag som skulle kunna parallellpubliceras enligt SHERPA/RoMEO, men där så inte skett. Ett vidare syfte har även varit att ta fram metodik för att skapa förutsättningar för framtida mätningar av svensk OA-publicering.

    The Share of Open Access in Sweden 2011: Analyzing the OA outcome from Swedish universities2014Inngår i: ScieCom Info, E-ISSN 1652-3202, Vol. 10, nr 2Artikkel i tidsskrift (Annet vitenskapelig)
    Abstract [en]

    Under 2013 genomfördes en studie över andelen open access (OA) i Sverige. Projektet finansierades av Kungliga bibliotekets program Openaccess.se. I undersökningen, som använde SwePub som index, studerades hur stor del av svenska forskningsartiklar med publiceringsår 2011 som är OA. Analysen gäller dels andelen guld och grön OA, men också hur stor del av de publicerade artiklarna som skulle kunna parallellpubliceras enligt förlagens villkor. Analysen visar att andelen OA-artiklar som publicerades under år 2011 uppgick till cirka 17 procent, varav guld OA 10 procent och grön OA 10 procent. Detta indikerar ett överlapp av artiklar som är både guld och grön OA på cirka 3 procent. Räknar man även in så kallat fördröjd OA så uppgår den totala mängden OA-artiklar år 2011 till uppemot 25 procent. Resultatet visar vidare att ytterligare en stor mängd artiklar skulle kunna parallellpubliceras enligt informationen i Sherpa/RoMEO.

    Biblioteks-och informationsvetenskap–en positionsbestämning: Svenska avhandlingar och uppsatser i en interpretativ innehållsanalys2013Independent thesis Advanced level (degree of Master (Two Years)), 20 poäng / 30 hpOppgave
    Abstract [en]

    The purpose of this study is to gauge the current state of Swedish library and information science research. LIS is generally defined as a cross- or multidisciplinary subject, according to some coupled with heterogenity or dichotomy within the subject. In light of Jack Meadows’s description of the scientific community growth and scientific communication, the following two research questions are formulated as basis for the study: 1. What are the current themes, what range of theories and methods are used in our research material? 2. What are the relationships between our research material with respect to choice of themes, theories and methods used, compared with the image given in earlier studies of LIS research? Our research material consists of all Swedish licentiate and doctoral theses in LIS defended at Swedish universities 1993-2011 and all master’s theses published at three different Swedish LIS departments (Borås, Lund and Uppsala) during the years 2008-2009. The theses have been collected and processed using an interpretative content analysis, which includes categorisation of themes, theories and methods, as well as statistical analysis. A compilation of the results suggests the dominance of certain categories of themes, theories and methods. The dominating themes are focused on different aspects of the Library as an entity. The dominating theories are sociological or philosophical (used alone or in combination), and the prominent methods used are interviews and text analysis. The results overall agree with earlier studies from the 21st century. However, studies from the 1990s show a different distribution of theme categories in older research publications in LIS. This difference may be attributed to different research trends over time, but also to the specific versions of content analysis applied.

    Teaching information literacy for engineering students in a rapidly changing information landscape2016Inngår i: Nordic Journal of Information Literacy in Higher Education. Creating Knowledge VIII - Special Issue, 2016, Vol. 8Konferansepaper (Fagfellevurdert)
    Abstract [en]

    The KTH Library has a long tradition of teaching information searching to technology students. Over the last years teaching information searching has become teaching information literacy, including more evaluation and source criticism. Traditionally, there have been three forms of teaching: independent credit-giving courses, integrated shorter modules in subject-specific courses and support via individual face-to-face supervision.

    Although evaluation and source criticism are now important parts of our teaching, much focus is still on search methodology. During this spring we, and our teaching colleagues at the KTH library, will revise and develop the content and pedagogical methodology for the courses and integrated modules in information literacy. In doing so, we need to address important questions on how to face the changing information landscape.

    Should the teaching be adapted to the search behaviour observed in our students or should we keep trying to change that behaviour? Do we put our effort into directing students to traditional scientific subject databases or should we put more emphasis on the importance of critically evaluating the search results, regardless of their source? How do we find the balance between these alternatives?

    Recently published studies have already covered these questions to some extent. The findings from a systematic literature search, together with insights collected from our development work during Spring 2016, will be used in an analysis of these questions in the context of teaching information literacy for engineering students.

    Quadcopters or Linguistic Corpora: Establishing RDM Services for Small-Scale Data Producers at Big Universities.2018Inngår i: Proceedings of the 39th IATUL conference, Oslo Metropolitan University - University Library, Norway, 17 to 21 June 2018., 2018Konferansepaper (Fagfellevurdert)
    Abstract [en]

    During the IATUL Conference 2017, the authors had many productive exchanges about similari-ties and differences in Swedish and German higher-education libraries. Since research data management (RDM) is an emerging topicon both sides of the Baltic Sea, we find it valuable to compare strategies, services, and workflows to learn from each other’s practices. Aim: In this talk, we aim to compare the practices and needs of small-scale data producers in engineering and the humanities. In particular, we try to answer the following research questions: What kind of data do the small-scale data producers produce? What do these producers need in terms of RDM support? What then can we librarians help them with? Hypothesis: Our research hypothesis is that small-scale data producers have similar needs in engineering and the humanities. This hypothesis is based on the many similarities in demands from funding agencies on open data and on the assumption that research in different subjects often creates empirical results which are different in content but similar in structure. Method: We study the current strategies, practices, and services of our respective universities (KTH Royal Institute of Technology Stockholm and Westfälische Wilhelms-Universität Münster). We also study the work and initiatives done on a more advanced level by universities, libraries, and other organisations in Sweden and Germany (e.g. Stockholm University, Swedish National Data Service (SND), Cologne Center for eHumanities at the University of Cologne). Results: The talk will give an overview of how we did the groundwork for the initial services pro-vided by our libraries. We focus on what we are doing and in particular why we are doing it. We find that we are following in the leading footsteps of other university libraries. The experiences shared by colleagues help us to adapt their best practices to our local demands, making them better practices for KTH and WWU researchers.

    Kommunicera Open Access med forskare: Erfarenheter från KTHB 20152016Konferansepaper (Annet (populærvitenskap, debatt, mm))
    Abstract [sv]

    I januari 2015 fick enheten för Publiceringens infrastruktur vid Kungliga Tekniska högskolans bibliotek (KTHB) i uppdrag av KTH:s ledningsgrupp att genomföra en informationskampanj om Open Access (OA) med målet att öka KTH:s andel OA-publikationer, i synnerhet gröna/parallellpublicerade OA-publikationer. Under kampanjen besökte KTHB:s OA-ansvariga skolor och institutioner på KTH för att informera om OA och vilka verktyg som finns för att underlätta publicering, samt för att ta emot forskarnas synpunkter på OA-publicering. Sammanlagt blev det 23 besök med flera intressanta diskussioner om OA. De flesta forskarna var positiva till OA, men flera saknade kännedom om vilka praktiska möjligheter som finns för att genomföra det.

    Uppsökande verksamhet i form av en informationskampanj är ett sätt att öka forskarnas medvetenhet om OA-publicering och det stöd biblioteket kan ge. Vid vårt bord berättar vi mer om våra erfarenheter från informationskampanjen samt diskuterar:

    - Hur forskningsbiblioteken kan ta tillvara forskares synpunkter på och erfarenheter av OA-publicering.

    - Hur forskningsbiblioteken kan använda dessa lärdomar för att utveckla sitt forskarstöd.

    Samverkan mellan forskare och bibliotek: Mot en förändrad syn på publiceringsstrategier2014Inngår i: SVeP Studenttidskriften Vetenskaplig Publicering, Vol. 1, nr 1Artikkel i tidsskrift (Annet vitenskapelig)
    Abstract [sv]

    Universitets- och högskolebiblioteken har i allt större utsträckning fått en viktig roll att spela i spridandet av det egna lärosätets forskning. Detta ger utrymme för samarbete mellan bibliotek och forskare: biblioteket behöver kunskap om de faktorer som styr hur forskarna väljer att sprida sina resultat, för att i sin tur kunna ge forskarna stöd i valet av publiceringskanaler och publiceringsstrategier. I detta paper undersöker vi attityder och strategier hos fyra forskare med anknytning till Kungliga Tekniska högskolans bibliotek, samt föreslår möjliga vägar till samverkan mellan bibliotek och forskare.

    Towards field-adjusted production: Estimating research productivity from a zero-truncated distribution2016Inngår i: Journal of Informetrics, ISSN 1751-1577, E-ISSN 1875-5879, Vol. 10, nr 4, s. 1143-1152Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Measures of research productivity (e.g. peer reviewed papers per researcher) is a fundamental part of bibliometric studies, but is often restricted by the properties of the data available. This paper addresses that fundamental issue and presents a detailed method for estimation of productivity (peer reviewed papers per researcher) based on data available in bibliographic databases (e.g. Web of Science and Scopus). The method can, for example, be used to estimate average productivity in different fields, and such field reference values can be used to produce field adjusted production values. Being able to produce such field adjusted production values could dramatically increase the relevance of bibliometric rankings and other bibliometric performance indicators. The results indicate that the estimations are reasonably stable given a sufficiently large data set.
