Abstract:
An information storage, arching and retrieval system for large (gigabytes) domains of archived textual dam. The system includes multiple query generation process, a arch process, and a prentation of arch results that is sorted by category or type and that may be customized bad on the professional discipline(or analogous personal characteristic of the ur), thereby reducing the amount of time and cost required to retrieve relevant results.

1.INTRUDUCTION
This invention relates to an information storage, arching and retrieval system that incorporates a novel organization for prentation of arch results from large (gigabytes) domains of archived textual data.
女上式2.BACKGROUDN OF THE INVENTION
On-line information retrieval systems are utilized for arching and retrieving many kinds of information. Most systems ud today work in esntially the same manner; that is, urs log on (through a computer terminal or personal microcomputer, and typically from a remote location), lect a source of information (i.e., a particular databa) which is usually something less than the complete domain, formulate a query, launch the arch, and then review the arch results displayed on the terminal or microcomputer, typically with documents (or summaries of documents) displayed in rever chronological order. This process must be repeated each time another source (databa) or group of sources is lected (which is frequently necessary in order to insure all relevant documents have been found).Additionally, this process places on the ur the burden of organizing and as

similating the multiple results generated from the launch of the same query in each of the multiple sources (databas) that the ur needs (or wants) to arch. Prent systems that allow arching of large domains require persons eking information in the domains to attempt to modify their queries to reduce the arch results to a size that the ur can assimilate by browsing through them (thus, potentially eliminating relevant results).

In many cas end urs have been forced to u an intermediary (i.e., a professional archer) becau the current collections of sources are both complex and extensive, and effective arch strategies often vary significantly from one source to another. Even with such guidance, potential relevant answers are misd becau all potentially relevant databas or information sources are not arched on every query. Much effort has been expended on refining and improving source lection by grouping sources or databa files together. Significant effort has also been expended on query formulation through the u of knowledge bas and natural language processing. However, as the groupings of sources become larger, and the respons to more comprehensive arch q
ueries become more complete, the person eking information is often faced with the daunting task of sifting through large unorganized answer ts in an attempt to find the most relevant documents or information.
3.SUMMARY OF THE INVENTION
The invention provides an information storage, arching and retrieval system for a large domain of archived data of various types, in which the results of a arch are organized into discrete types of documents and groups of document types so that urs may easily identify relevant information more efficiently and more conveniently than systems currently in u. The system of the invention includes means for storing a large domain of data contained in multiple source records, at least some of the source records being comprid of individual documents of multiple document types; means for arching substantially all of the domain with a single arch query to identify documents responsive to the query; and means for categorizing documents responsive to the query bad on document type, including means for generating a summary of the number of do

The query generation process may contain a knowledge ba including a thesaurus that has predetermined and embedded complex arch queries, or u natural language processing, or fuzzy logic, or tree structures, or hierarchical relationship or a t of commands that allow persons eking information to formulate their queries.
The arch process can utilize any index and arch engine techniques including Boolean, vector, and probabilistic as long as a substantial portion of the entire domain of archived textual data is arched for each query and all documents found are returned to the organizing process.
The sorting/categorization process prepares the arch results for prentation by asmbling the various document types retrieved by the arch engine and then arranging the basic document types into sometimes broader categories that are readily understood by and relevant to the ur.The arch results are then prented to the ur
