    • 2. The Title• Mining Research Publication Networks for Impact04/06/2013 Drahomira Herrmannova
    • 3. Background• How to evaluate quality of research?• It is highly relevant to• Researchers – what to read, career progression• Librarians – subscriptions• Universities and other institutions – grants, promotions,…• Publishers – promoting their journals04/06/2013 Drahomira Herrmannova
    • 4. Background• At what granularity do you want to evaluate thequality of research?• Papers• Journals• Researchers• Research groups / institutions• Metrics created for evaluating at one level ofgranularity are often used for evaluating otherlevels04/06/2013 Drahomira Herrmannova
    • 5. Current situation• Many current widely used measures depend oncitation analysis• Well known examples• Journal Impact Factor (journals)• Citation counts (individuals, papers)• H-Index (individuals)• Advantages• Simple and clear metrics• Well available04/06/2013 Drahomira Herrmannova
    • 6. Current situation04/06/2013 Drahomira Herrmannova
    • 7. Concerns• Not an accurate evidence of quality of a paper• Traditional methods often ignore• Reasons for citation• Co-authorship• Self-citation• Article type• Citation half-life• …04/06/2013 Drahomira Herrmannova
    • 8. Concerns• Many papers are never cited at all (Garfield, 2005)• “Citation half-life”• Can be up to several years long (Arnold, 2010)• “When metric becomes a target, it ceases to be agood metric” (Arnold, 2010)• Citation-based metrics are easily manipulated• Relationship between the paper and relatedliterature rests on the author04/06/2013 Drahomira Herrmannova
    • 9. Available data• Many possible types of data that can be used toevaluate research output• Citations• Usage• Blog coverage• Discussion threads• Social bookmarking• …04/06/2013 Drahomira Herrmannova• Fulltext of publication• Expert reviewIs it possible to evaluateresearch based just on whatpeople say about it?
    • 10. Methods• Metrics based on web data (altmetrics,webometrics)• File accesses and downloads• Mentions, comments and annotations• Citations and bookmarks• …• Methods based on analysing fulltext of papers• Semantic relatedness of papers• Context of citation04/06/2013 Drahomira Herrmannova
    • 11. Methods• Methods based on citations• Citation graph• Co-authorship network of researchers• Other methods• Using patent information• …04/06/2013 Drahomira Herrmannova
    • 12. Methods• Despite the number of possibilities still nostandard solution that would help up to addressthe issues• Bridge the time gap between publishing a paper andreceiving first citations• Explain the reason and meaning of quality of a paper• …04/06/2013 Drahomira Herrmannova
    • 13. Project topic• Design new methods for improving evaluation ofquality of research which will address thementioned challenges04/06/2013 Drahomira Herrmannova
    • 14. Questions and goals• Evaluate how the impact measures based oncitations represent the quality of a paper• Analyse which other factors, in addition tocitations, affect the quality of a publication04/06/2013 Drahomira Herrmannova
