    Exploring the relation between referencing practices and citation impact: A large-scale study based on Web of Science data2018In: Journal of the Association for Information Science and Technology, ISSN 2330-1635, E-ISSN 2330-1643, Vol. 69, no 5, p. 728-743Article in journal (Refereed)
    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.

    Open Access-publicering vid svenska lärosäten : en kartläggning av året 20112014Report (Other academic)
    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 universities2014In: ScieCom Info, E-ISSN 1652-3202, Vol. 10, no 2Article in journal (Other academic)
    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.

    Swedish and Nordic institute collaboration networks over time - between institute ego-networks and fields2012Conference paper (Other academic)
    Abstract [en]

    The study represents an analysis of a group of institutes included in RISE (Research Institutes of Sweden) representing a wide range of activities from research in forestry, ICT, and also areas such as surface chemistry. The aim was to examine publication patterns over time and also analyze international collaboration in the broader context of technical-industrial institutes in Nordic countries.

    A bibliometric analysis was conducted by searching Web of Science for publications containing the addresses of RISE institutes published 2002-2011. A publication count was done for the individual institutes, for an aggregated level dividing the institutes into four groups (Swedish ICT, SP, SWEREA, Innventia/STFI), and as total counts for the whole RISE group. To analyze the collaboration network of the RISE group, frequencies of organizations and countries in the publication set were calculated and co-occurrence visualizations conducted.

    The preliminary results show an increasing publication frequency at the aggregated level. Also the international collaboration, measured by the share of internationally co-authored publications, has been augmenting, from about 31 percent in 2002 to about 43 percent in 2011. Nevertheless, in Sweden, universities are still the most common collaborators and the network analysis shows that there are extensive knowledge networks between local research partners.
