Citation Indexes to Integrated Information Resources and Beyond: Navigating Scholarly Information to Accelerate Discovery John A. Adams Senior Manager, Product Development ISI October 3, 2001

The Vision: Cited references & scholarly discovery ISI Web of Knowledge SM platform Phase I of the platform An additional search engine Links management system ISI platform: future directions From print to Web - current ISI offerings

The Vision: Cited references & scholarly discovery äDr. Eugene Garfield: 1955 article in Science äCited references: more than acknowledgements, but links to discover hidden conceptual relationships ä Cited reference searching: no specialised vocabulary (the reference is the search term) ä Citation analysis concepts äBibliographic coupling (M.M. Kessler), äCo-citation clustering (E. Garfield, H. Small), äCitation rankings, Impact factors

From print to the ISI Web of Science ä Print; Online; Magnetic Tape; CD-ROM ä Web: finally, the right technology ä ISI Web of Science ® (Introduced in 1997) Citation indexes through a Web interface äTraditional Bibliographic Boolean Searching äCitation Searching äCitation Navigation (Cited References, Times Cited) äBack files (SCIE ) (SSCI ) (A&HCI ) äAverage Back File subscription is 17 Years äAggressive feature development (upcoming Version 5.0)

Additional Products äRetrospective Products Derwent Innovation Index SM ISI Proceedings SM äSpecialized Content Products ISI Chemistry SM BIOSIS ® Previews äCurrent Awareness Products Current Contents Connect ®  Evaluation / Analytical Products Journal Citation Report ® on the Web ISI Essential Science Indicators SM

Introduce the ISI Web of Knowledge SM platform äLink bibliographic records to the full text äLink similar records between various products for value add data äLinks features between products äISI Web of Knowledge SM platform (2001): All ISI resources in a single, Web-based environment for navigating quickly and easily through research- oriented/ scholarly information, anytime, from the desktop

ISI Web of Knowledge platform: Phase I (2001) Content äEvaluated, multidisciplinary äDiverse (journals, proceedings, patents, chemical compounds and reactions, Web sites and Web documents) äEnhanced by complementary, subject-specific coverage Tools äSearching, browsing, alerting, linking, exporting New Technologies äMuscatDiscovery TM an advanced indexing and retrieval technology from SmartLogic TM Group, PLC äISI Links Gateway for centralised links management

Muscat Query Engine äTraditional ISI engines: Boolean (“exact match” systems) äModular infrastructure allows quick implementation äNew: MuscatDiscovery query engine ä Probabilistic model (“close match” system) ä Searching both structured and unstructured data ä Relevance, weighting of terms; supports Boolean ä Two applications: ä Automatic searching of full-text of Web documents ä Cross-content searching

äIntegrates journal article retrieval with Web document retrieval without disrupting the search process äTakes Boolean search terms and translates to 2-part query (selection, then weighting) äAutomatically retrieves evaluated Web documents from Current Web Contents ISI eSearch SM : full-text search of Web documents

ISI eSearch

ISI CrossSearch: cross-content searching ä“Concept” searching of different journals, proceedings, patents from a single interface, with consolidated results äDynamic “Boolean Form” searching, based on users selections äDe-duplicated summary list with multi-product access äSingle-sessioning across resources äThis is the first phase of the ISI Web of Knowledge of platform

ISI CrossSearch: cross-content searching

The ISI Links Gateway äLinking Questions äWho is the user? Where does the user want to go? What is the appropriate copy/ instance? äPast: product-by-product duplication of authentication, access, and routing äCurrent: central server for all links management ä Intra- and inter-content links ä Customer archives (OPACs) ä SFX context-sensitive reference links ä Links to publisher full-text

RoboLinks: hybrid linking system ä “No Dead Links” policy ä Direct electronic feeds from publishers = stability ä Algorithmic (“optimistic”) links ä Other algorithmic links try to create a link on demand ä ISI RoboLinks: pre-verifies the link ä Provides stability while allowing expansion ä 2,500+ full-text titles and counting

ISI Web of Knowledge

ISI Web of Knowledge platform: Future äIntroduce a Portal environment äExpanding content sources to complementary, subject- specific resources through new partnerships ä CAB Abstracts (agriculture) ä INSPEC (engineering) ä Extending all tools across all content in the platform ä Expansion of full-text links and SFX-enabling äContinued development of features in individual resources (advanced set-searching in WoS)
