  1. CitEc as a source for research assessment and evaluation José Manuel Barrueco Universitat de València (SPAIN) May, 2016 5-й Международной научно-практической конференции «Научное издание международного уровня – 2016: проблем издательской этики, рецензирования и подготовки публикаций», 17-20 мая, 2016

  2. Citations and citation indexes • Citations are indicators of the quality of a publication and therefore a key piece in any execise of research assesment • Bibliometric indicators (impact factor, h-index) are used (and often misused) for research evaluation purposes • Citation-based measures should complement expert peer-review and never supplant it • Research evaluation requires citation indexes in order to provide current and accurate citation data • For many years the only source of citation data were the indexes published by ISI (now Thomson Reuters) • Fortunately the landscape has changed … 5-й Международной научно-практической конференции «Научное издание международного уровня – 2016: проблем издательской этики, рецензирования и подготовки публикаций», 17-20 мая, 2016

  3. Citations and citation indexes • Thebigplayers: Thomson’s Web of Science and ScopusbyElsevier • Scholarlydatabases: PubMed or those from Cambridge Scientific, EBSCO, … • Intermediate services: Mendeley, PlumX or KUDOS are using citation data extracted from Scopus, WoS or CrossRef in their products • Social research networks: ResearchGate • Repositories: arXiv in physics or SSRN in social sciences • Atonomous citation indexes: • CiteSeer in computer science • CitEc in economics • Google Scholar Citations 5-й Международной научно-практической конференции «Научное издание международного уровня – 2016: проблем издательской этики, рецензирования и подготовки публикаций», 17-20 мая, 2016

  4. A few words about RePEc • RePEc (ResearchPapers in Economics) is a digital library • RePEc describes thewhole discipline: • Research outputs (articles, papers, chapters, books) • Publicationchannels (journals, workingpapers series …) • Researchers • Institutions (departments, researchinstitutes …) • RePEcarchitecture: data providers vs. serviceproviders • RePEc in numbers: • +2,000,000  research outputs • Comingfrom more than 1,300 data providers • Universitydepartments, internationalinstitutions, banks, publishers … • +46,000  authorcontact and publicationlistings 5-й Международной научно-практической конференции «Научное издание международного уровня – 2016: проблем издательской этики, рецензирования и подготовки публикаций», 17-20 мая, 2016

  5. CitEc : an autonomous citation index • It is a RePEc service <http://citec.repec.org> • Processes, extracts and disseminates citation data for RePEc • A citation dataset of: • +22,000,000 references • +8,000,000 citations • +812,000 documents processed (about 40% of the available documents) • CitEc produces open citation data • As other RePEc services, CitEc is based on volunteer work • No permanent funding • Server sponsored by INOMICS • Funds raised since 2014-02-04: 525 EUR 5-й Международной научно-практической конференции «Научное издание международного уровня – 2016: проблем издательской этики, рецензирования и подготовки публикаций», 17-20 мая, 2016

  6. CitEc : an autonomous citation index • Data generation: • All RePEc documents could become cited documents • 40% of the available documents are citing documents: • Full text not available: not in electronic format, not open access, not at the url provided … • Unable to process full text to extract references (i.e. digitized documents) • Data input: • PDFs provided by data providers • Need to convert PDF files to text in order to extract references • Process prone to errors: references lost, incorrect interpretation of characters … • Data providers need to do nothing about it • XML structured metadata about references • Good quality results • Only large publishers (Elsevier or Springer) are able to cope with this format • Nonetheless, around 60% of the references available come this way 5-й Международной научно-практической конференции «Научное издание международного уровня – 2016: проблем издательской этики, рецензирования и подготовки публикаций», 17-20 мая, 2016

  7. CitEc : an autonomous citation index • Quality control: • It relies on the reserchers community • Involves detecting and reporting wrong or missing content • Transparency and publicity of the data • Reporting of errors as easy as posible • at reference and document levels • Registered authors may: • Add references lists. Submitter data is logged and shown in web pages • Identify missing citations to their works. Only applies to suspect citations identified by the system. Author may claim or refuse them • Any CitEc user may: • Add missing citations to any document. All data is checked for correctness 5-й Международной научно-практической конференции «Научное издание международного уровня – 2016: проблем издательской этики, рецензирования и подготовки публикаций», 17-20 мая, 2016

  9. Research evaluation trougth CitEc • Citation data cleaned in order to • Remove self-citations • Aggregation of cites between different versions of the same document • Evaluation at three levels: • Documents • Researchers • Institutions • Two evaluation tools • Citations profiles • Rankings 5-й Международной научно-практической конференции «Научное издание международного уровня – 2016: проблем издательской этики, рецензирования и подготовки публикаций», 17-20 мая, 2016

  10. Research evaluation • Citation profiles • Authors (46K profiles) • Research production: number of works published and their distribution by year and document type; books and journals edited; journals or series where she publishes. • Citation counts: total number of citations, unbundled number of citations by work, recent citing documents, total and percentage of self-citations. • Relationship with other researchers: co-authors, who is citing him or to whom he cites. • Basic bibliometric indicators like h-index and i10-index. • Series (2K journals and 4K working papers series) • Production and citation count data in time series that could be back to 1990 • Bibliometric indicators: impact factor, immediacy index and h-index • Institutions • To come!! 5-й Международной научно-практической конференции «Научное издание международного уровня – 2016: проблем издательской этики, рецензирования и подготовки публикаций», 17-20 мая, 2016
