The Vision: Cited references & scholarly discovery

ISI Web of KnowledgeSM 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

Dr. Eugene Garfield: 1955 article in Science

Cited references: more than acknowledgements, but links to discover hidden conceptual relationships

Cited reference searching: no specialised vocabulary (the reference is the search term)

Citation analysis conceptsBibliographic coupling (M.M. Kessler),

Co-citation clustering (E. Garfield, H. Small),

Citation rankings, Impact factors

From print to the ISI Web of Science Print; Online; Magnetic Tape; CD-ROM

Web: finally, the right technology

ISI Web of Science ® (Introduced in 1997)

Citation indexes through a Web interfaceTraditional Bibliographic Boolean Searching

Citation Searching

Citation Navigation (Cited References, Times Cited)

Back files (SCIE - 1945) (SSCI - 1956) (A&HCI - 1975)

Average Back File subscription is 17 Years

Aggressive feature development (upcoming Version 5.0)

Introduce the ISI Web of KnowledgeSM platform

Link bibliographic records to the full text

Link similar records between various products for value add data

Links features between products

ISI Web of KnowledgeSM 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 Evaluated, multidisciplinary

Diverse (journals, proceedings, patents, chemical compounds and reactions, Web sites and Web documents)

Enhanced by complementary, subject-specific coverage

Tools Searching, browsing, alerting, linking, exporting

New Technologies MuscatDiscoveryTM an advanced indexing and retrieval technology

from SmartLogicTM Group, PLC

ISI Links Gateway for centralised links management

Muscat Query Engine

Traditional ISI engines: Boolean (“exact match” systems)

Modular infrastructure allows quick implementation

New: MuscatDiscovery query engine Probabilistic model (“close match” system)

Searching both structured and unstructured data

Relevance, weighting of terms; supports Boolean

Two applications:

Automatic searching of full-text of Web documents

Cross-content searching

Integrates journal article retrieval with Web document retrieval without disrupting the search process

Takes Boolean search terms and translates to 2-part query (selection, then weighting)

Automatically retrieves evaluated Web documents from Current Web Contents

ISI eSearchSM: full-text search of Web documents

ISI eSearch

ISI CrossSearch: cross-content searching

“Concept” searching of different journals, proceedings, patents from a single interface, with consolidated results

Dynamic “Boolean Form” searching, based on users selections

De-duplicated summary list with multi-product access

Single-sessioning across resources

This is the first phase of the ISI Web of Knowledge of platform

ISI CrossSearch: cross-content searching

The ISI Links Gateway

Linking Questions Who is the user? Where does the user want to go?

What is the appropriate copy/ instance?

Past: product-by-product duplication of authentication, access, and routing

Current: central server for all links management

Intra- and inter-content links

Customer archives (OPACs)

SFX context-sensitive reference links

Links to publisher full-text

RoboLinks: hybrid linking system

“No Dead Links” policy

Direct electronic feeds from publishers = stability

Algorithmic (“optimistic”) links

Other algorithmic links try to create a link on demand

ISI RoboLinks: pre-verifies the link

Provides stability while allowing expansion

2,500+ full-text titles and counting

ISI Web of Knowledge

ISI Web of Knowledge platform: Future

Introduce a Portal environment

Expanding content sources to complementary, subject-specific resources through new partnerships

CAB Abstracts (agriculture)

INSPEC (engineering)

Extending all tools across all content in the platform

Expansion of full-text links and SFX-enabling

Continued development of features in individual resources (advanced set-searching in WoS)
