+++ Bielefeld University Library: Launch of the "BASE - Bielefeld Academic Search Engine "- Demonstrator http://base.ub.uni-bielefeld.de +++
Dear colleagues,
It's my great pleasure to inform you, that the demonstrator "BASE Digital Collections", our search engine technology prototype, has gone life for the general public!
BASE, the Bielefeld Academic Search Engine, is the local implementation of a search service prototype, that can have in the future many other access points and brandings, e.g. in your own local or subject specific information discovery environment. "BASE Digital Collections" comprises a group of non-subject specific digital collections incl. institutional repositories, digitised collections, e-journals, pre-print servers and other full texts from Germany, the U.S. and the UK. The "BASE Digital Collections" builds the prototype of a real-life search service to digital collections that are not restricted to a specific subject area. Beyond partial digital collections of various partners it includes the complete digitised collections of historical German journals (Host: Bielefeld UL) and the "Internet Library of Early Journals, ILEJ" (Host: Oxford University Library Services). Further collections are scheduled for inclusion. BASE Mathematics, a further version of the demonstrator, includes two further repositories, the complete mathematical records of the Bielefeld Online Library Catalogue and a subset of the "Zentralblatt Math"-database.
Key objectives of the planned new search service include:
++To create an integrated point of access to very heterogeneous and distributed online content ++To offer access only to qualified, scholarly content ++To include resources that are usually not covered by commercial search indexes because they cannot be crawled automatically (the so- called "deep" or "invisible" web) ++Combine the proven strengths of commercial internet indexes (performance, scalability, comfort in use) with the traditional strength of libraries to identify and index high quality scholarly content
The demonstrators can only give a first glance on the potential of search engine technology in the context of scholarly search- and retrieval services. The underlying indexing technology of the Fast company has only partially been exploited and system components like the linguistic modules haven't even been implemented yet. Further activities, that are scheduled for evaluation, implementation or development include among others:
++The extension of the current index structure which is mainly built on the 15 Dublin Core fields ++The optimising of ranking algorithms for scientifically relevant documents ++Implementation and customisation of existing linguistic features to support intelligent querying ++The development of intelligent and flexible search-/navigation and retrieval interfaces
The further evaluation and large-scale implementation of search engine technology into digital libraries and scholarly information portals is one objective of a national project initiative "Distributed Document Server" that is seeking funding through the Deutsche Forschungsgemeinschaft and the German Federal Ministry of Education and Research, incorporated also into "vascoda", the German Digital Library project.
The set-up of BASE is grounded on a strategic collaboration of Bielefeld University Library and Fast Search & Transfer ASA, one of the market leaders for intelligent search technology. Fast, an off- shoot of the Norwegian National University of Technology, is based in Oslo with branches in some European countries, the U.S. and Japan. Research laboratories are located in Norway and at the universities of Munich (Germany), Cornell and Penn. State (U.S.). Fast technology has been the indexing technology for the AllTheWeb internet search index.
The public launch of the BASE demonstrators is supported by a programmatic article on "Search engine technology and digital libraries: Libraries need to discover the academic internet", published in the June issue of the D-Lib Magazine (www.dlib.org).
Comments and suggestion are welcomed and encouraged.
