  1. Distributed Open Access Reference Citations Service Michael Maune Carl von Ossietzky University, Oldenburg and Institute for Science Networking Oldenburg

  2. Introduction • Developed as back-end-service • Aggregating meta-data from institutional repositories • Enriching meta-data • Discovering the citation-graph • CSN as first test-community • Runtime: 18 months (DFG-Funded) Michael Maune, Carl von Ossietzky University, ISN

  3. Project partners • Volker Mellert • Carl von Ossietzky University, Oldenburg (CvO) • Eberhard R. Hilf • Institute für Science Networking Oldenburg GmbH (ISN) • Peter Schirmbacher and Frank Havemann • Berlin school for information and library science (IBI), Humboldt-University Berlin • Wolfgang Christen • Institute of Chemistry (IfC), Humboldt-University Berlin Michael Maune, Carl von Ossietzky University, ISN

  4. Aims and concept • Integrating and developing tools for literature management • Exchange of meta-data • Enrich of meta-data • Interactive visualization of document-relations • Reference-analysis Michael Maune, Carl von Ossietzky University, ISN

  5. Embedding into the Network Michael Maune, Carl von Ossietzky University, ISN

  6. Cooperation with OANetwork • OAN as user-interface and data-provider • Usage of OAN technology • Fulltext-crawler • Dublicate-checker • Classificator • Exchange of metadata between OAN and DOARC Michael Maune, Carl von Ossietzky University, ISN

  7. Content relation of documents • Field-specific definition • Identifying field-specific word-combinations • Building field-specific fingerprints • Assigning new documents to fields • Field-specific thesaurus • Usage of lexical analysis • Identifying thematically similar documents Michael Maune, Carl von Ossietzky University, ISN

  8. Cooperation with AuthorClaim.org • AuthorClaim database is synced with DOARC • Small set of meta-data (title, authors, url) • Information about claimed and unclaimed documents • Information of claimed and unclaimed documents used in user-interface • Encourage authors to use AuthorClaim Michael Maune, Carl von Ossietzky University, ISN

  9. Claiming of authorship using ACIS • Usage of the Author Contribution Information System (ACIS) • Author registers to the system • Sets up a list of acronyms • Claims affiliation with institutions • Gets displayed a list of possible publications • Claims/rejects the listed papers Michael Maune, Carl von Ossietzky University, ISN

  10. Benefits • Added value for authors by claiming their publications • Increasing the data-space on both sides • More documents for authors to claim • More documents for readers to find • Increasing the quality of meta-data Michael Maune, Carl von Ossietzky University, ISN

  11. Citation Networking Size of nodes = number of citings Color of nodes= relevance Strength of link = similarity http://doarc.projects.isn-oldenburg.de Michael Maune, Carl von Ossietzky University, ISN

  12. Network-graphs of papers • Different dimensions of probability • Bibliographic coupling • Co-citing • Lexical coupling • Different ways to visualize the similarity • Network-graphs • Sortable lists Michael Maune, Carl von Ossietzky University, ISN

  13. Data import and coverage • Data im-/export in different ways • OAI-PMH • BibTeX/EndNote • Author-Publication-Lists • Proprietary Provider-APIs • Get the biggest possible set of meta-data • Aggregate and enrich this meta-data Michael Maune, Carl von Ossietzky University, ISN

  14. Aims of DOARC • Higher usage of OA-documents resulting from better visibility • Supporting Authors in action • Finding thematically relevant publications • Simple usage of metadata (Import/Export) • OA-publishing with complete meta-data Michael Maune, Carl von Ossietzky University, ISN

  15. Author- and user-tools • Support through the whole writing process • Making it easy to find relevant papers • Add papers to a reference-list • Exporting this reference-list in preferred format • Upload the document incl. reference-list • Enter further meta-data • Export own publiction-list Michael Maune, Carl von Ossietzky University, ISN

  16. Prospects and future • Expanding data-space • Expand from german OA-sources to international sources • Further enhancing the reference-extraction-tools Michael Maune, Carl von Ossietzky University, ISN
