Cheshire II - Two-Stage Retrieval
Using the LC Classification System
- Pseudo-Document created for each LC class containing terms derived from “content-rich” portions of documents in that class (subject headings, titles, etc.)
- Permits searching by any term in the class
- Ranked Probabilistic retrieval techniques attempt to present the “Best Matches” to a query first.
- User selects classes to feed back for the “second stage” search of documents.
Can be used with any classified/Indexed collection.
