Royal Netherlands Academy of Arts and Sciences KNAW Research Information National focal point research information Dutch Research Database (NOD) – the national CRIS Scientific communication (thematic databases, overview articles; e.g. about nanotechnology) Research information system and repository of the Academy Development of NARCIS…

Royal Netherlands Academy of Arts and Sciences What is NARCIS?

Royal Netherlands Academy of Arts and Sciences NARCIS is a portal that combines: Structured research information, about current research, researchers, and research institutes Information from academic repositories, (full text) publications, and others research results Information from websites of research institutes: datasets, digital publications, and news items All these types of information are searchable at the same time.

Royal Netherlands Academy of Arts and Sciences Partners in the NARCIS project Royal Netherlands Academy of Arts and Sciences (KNAW), department of Research Information Netherlands Organisation for Scientific Research (NWO) Association of Universities in the Netherlands (VSNU) Information Centre of the Radboud University of Nijmegen, (RU-UCI) Funded by the DARE programme

Royal Netherlands Academy of Arts and Sciences DARE: Digital Academic REpositories Joint initiative by the Dutch universities, the KNAW, NWO and the National Library DAREnet gives free access to academic research output in the Netherlands. DAREnet contains now about digital files from 16 institutes

Royal Netherlands Academy of Arts and Sciences Goals of the NARCIS project Giving an overview of research in the Netherlands Central place for searching all the different types of data Data collection via the already existing administrative systems of the participating institutes Registering of data once only Minimization of administrative report burden for researchers and institutes

Royal Netherlands Academy of Arts and Sciences

Content of NARCIS Information on 400,000 items:  Research institutes- profiles, addresses, programmes, projects  Researchers- expertise, addresses, projects, publications  Research activities- research programmes and projects  (web) publications- metadata, full text  Datasets- metadata  News items- webpages of research institutes

Royal Netherlands Academy of Arts and Sciences Advantages for the users The different types of research information are searchable at the same time (one-stop-shopping) Free access to Dutch academic full text publications and other research results Up-to-date information: data gathered in an early stage of the registration process High quality information: editors select the sources of NARCIS Overview of Dutch scientific output Scientific information also from repositories and websites

NARCIS: part two Technical background User Surveys Future Developments

Royal Netherlands Academy of Arts and Sciences Applied Techniques METIS-NARCIS exchange schema NWOdelfi-METIS interface OAI-PMH Web-crawling Collexis categorising RSS

Royal Netherlands Academy of Arts and Sciences METIS Dutch Research Information System Used by all Dutch universities For both research management and information supply Information on research groups, individual researchers, research output

Royal Netherlands Academy of Arts and Sciences Exchanging METIS info XML-schema (CERIF-based) developed by KNAW, NWO and RU; Implemented in METIS For service-provider accessible via URL XML-export to service provider automatically generated Data-provider no longer needs to create reports of new entered research projects in its METIS-system

Royal Netherlands Academy of Arts and Sciences Interface NWOdelfi-METIS enables xml-data exchange between METIS and NWOdelfi (with a copy to NARCIS) uses webservices with xml-SOAP

Royal Netherlands Academy of Arts and Sciences Advantages of the interface minimization of administrative report burden: -NWO granted projects sent automatically to the university-METIS systems (with a CC to NARCIS) -In METIS-system entered research output data (bibliographic descriptions of publications) automatically sent to NWO (with a CC to NARCIS)

Royal Netherlands Academy of Arts and Sciences OAI-PMH ( Open Archives Initiative Protocol for Metadata Harvesting) Darenet is a good example protocol for harvesting metadata descriptions (xml-documents) of full-text records in a repository

Royal Netherlands Academy of Arts and Sciences Web-crawling used for harvesting of data not available via METIS or NWO or repositories focused on non-university research institutes J-spider based spidering of news-items and of ‘web-publications’ (i.e. digital publications available on webpages of research institutes)

Royal Netherlands Academy of Arts and Sciences Categorising indexing all the data retrievable via NARCIS via one terminology system Dutch Research Database classification system is used first attempt: via Lucene search engine now: via Collexis software

Royal Netherlands Academy of Arts and Sciences METIS Webpages Institutional Repositories NARCIS Web-formsNWO NOD Categorizer

Royal Netherlands Academy of Arts and Sciences Notification tool: RSS feed content RSS-feed normally news-provider based (see BBC RSS-feed) In NARCIS: RSS-feed search action based User decides which information he regularly will be notified on

Royal Netherlands Academy of Arts and Sciences User Surveys

Royal Netherlands Academy of Arts and Sciences Preliminary results two user surveys conducted: amongst repository specialists (library personnel) amongst researchers, policy advisors and science education officers goals of the survey: impression and functionality of the NARCIS homepage search and limit functionality test imput for further improvement of the site

Royal Netherlands Academy of Arts and Sciences Outcomes user surveys :1 NARCIS-webview appreciated Retrieval of web publications is value adding service Quality of research information is high Broad range of search options and search performance

Royal Netherlands Academy of Arts and Sciences Outcomes user surveys : 2 complexity of NARCIS-portal urges a need for extra clarification of the possibilities of the contents and search tools limiting options too complicated users see NARCIS as a new independent information system, instead as a shell around existing ones presenting search results not only by relevance but also chronologically

Royal Netherlands Academy of Arts and Sciences Outcomes user surveys : 3 presentation of information that has been spidered leads to some confusion

Royal Netherlands Academy of Arts and Sciences

Future developments: technical automatic categorisation of the contents via Collexis working with Digital Identifiers (for authors, institutes and objects) in order to connect the Dutch CRIS systems to the repositories including CV-information of Dutch research into NARCIS (PROMAS)

Royal Netherlands Academy of Arts and Sciences Future developments: organisational installation of a NARCIS Advisory Board, formed by KNAW NWO VSNU plus: SURF the Advisory Board will decide in which way NARCIS will be developed

Royal Netherlands Academy of Arts and Sciences Conclusions national research information portal 400,000 items many different information types one stop shopping RSS-feed new xml exhange schema
