Today’s Presentation – Introduction: issues for the hybrid library – Content sources: native, hosted, and external – New technologies for integrated searching – Probabilistic search engines – Meta-search engines – WebFeat – Personalization of Search Utilities – Conclusion
3
The hybrid library "The challenge associated with the management of the hybrid library is to encourage end-user resource discovery and information use, in a variety of formats and from a number of local and remote sources, in a seamlessly integrated way.” (S. Pinfield, 1998) – Numerous providers, disparate formats – Local, consortial, national, international collaboration – Internet, intranet, mixed mode systems – Proprietary databases, subscriptions, full-text – Library training materials, administrative information – Enterprise solutions / The library “portal” – Users need to feel a part of the solution
4
The role of the information provider – Provide integrated content specifically designed to work within the library portal environment – Example: ISI Web of Knowledge
5
Types of content sources Native content: an organisation’s core information – Examples: Library training materials; electronic theses and dissertations Hosted content: developed through partnerships – Example: bibliographic data from information vendor provided through Library system/interface External content: from source outside the organization – Example: bibliographic data from information vendor provided through vendor system/interface
6
Native content – Examples: ISI Web of Science, Current Contents Connect, ISI Essential Science Indicators Hosted content – Examples: BIOSIS Previews, CAB ABSTRACTS, INSPEC, FSTA External content – Examples: PubMed, Agricola, Web Collections (from Current Web Contents), other databases via WebFeat Types of content sources: ISI example
7
New technologies for search integration Traditional Boolean information retrieval paradigm has been enhanced with: 1.Probabilistic search engines 2.Meta-search engines
8
1. Probabilistic search engines New paradigm – Not based on algebraic relationship of terms – Focus on the “concept” behind the search terms – Weighting of terms, applying “relevance” ISI Example – muscatdiscovery (from Smartlogik) – WebFeat (from WebFeat Inc.)
9
muscatdiscovery in ISI Web of Knowledge ISI CrossSearch – Enter words, phrase, or sentence into “concept” search box – User selects databases, editions, time frame, and “relevance” level Current Contents eSearch – Enter Boolean terms into Current Contents Connect – Translates “behind-the-scenes” into probabilistic query – Searches Web content automatically
10
2. Meta-search engines For true cross-collection discovery Single search query to multiple content sources Four basic components – Database selector – Document selector – Query dispatcher – Results merger
11
Meta-search engine architecture Database selector – Identify databases to be searched Document selector – Determine exact items to retrieve Query dispatcher – Transmit individual queries to each database Results merger – Return consolidated summary results list
12
Meta-search engine architecture* RESULTS... Interface to meta- search engine … SEARCH Database Selector Document Selector Query Dispatcher Database 2 Database 1 Results Merger * From “Building Efficient and Effective Metasearch Engines”, W. Meng, C. Yu, and KL Liu, (in press)

16
Document selector: future possibilities Dynamic categorization: refines search by adding context – Example: anthrax Viral mechanisms? Government policy? Alternative music group? Collecting metrics on different databases – Example: which databases have high return rates?
17
CrossSearch query dispatcher Determine translation and mapping rules Send query in correct syntax for each database Example: title search on heart attack for “current week” – Web of Science: heart attack – PubMed: heart attack[ti] and 2002/03/01:2002/03/08[edat]

® A new solution: federated searching with WebFeat –Provides one search interface for all your library’s electronic resources –Supports searching of OPACs, bibliographic subscription databases, full-text resources, electronic reference materials, proprietary content –Is not meant to replace searching of individual scientific and scholarly databases but to provide an initial point of access for: Undergraduates and novice library users who need “a starting point” All library users who want a quick discovery tool
24
The best federated search solution: WebFeat –What Z39.50 tried to do but couldn’t –Offers sophisticated technology including an extensive collection of database-specific “translators” –Implements easily on your library portal –Will be integrated seamlessly with ISI Web of Knowledge environment Four ways in which WebFeat outshines the rest... ® ISI and WebFeat, Inc. partnering to provide the best in federated searching to Academic and Government institutions worldwide
25
1. WebFeat is a service, not just a software package. –Internet-based because we use our server not yours –Minimal set-up because we handle the implementation (loading software, configuring database translators, and setting authentication/access based on your entitlements) –No ongoing maintenance because WebFeat regularly updates the database translators, and your ISI account manager will be your single point of contact for all questions, modifications, and problem-solving Compare this with competitor packages that require your library staff to handle all set-up, maintenance, and trouble-shooting. ®
26
2. WebFeat is fully customizable. –Individual screen elements can be placed wherever you want them on the screen –The interface reflects the look-and-feel of your institution, not the look-and-feel of WebFeat –Search screens customized for each site is possible because of its versatile authentication management –Results display can be customized to include special hotlinks or a database “scoreboard” ®
27
WebFeat integration with ISI Web of Knowledge For mutual subscribers, the WebFeat system is implemented both on your library portal and within ISI Web of Knowledge offering two ways of cross- collection discovery. ® –Reseachers and faculty who rely on the Web of Science and other ISI databases start from the ISI Web of Knowledge homepage and are led to your other library resources if they choose

Conclusions New technologies and standards: – Help address current problems but also allow development of new publishing models that further complicate our tasks and can leave the user confused. Goal for librarians: – Organise rather than consolidate: choose products from information leaders that offer new technologies for organization, searching, linking and personal customization. Goal for information providers: – Help librarians organize options for end-users – Provide integrated products that are designed to work within the digital library environment and so satisfying their customers’ needs.
