Abstract

An integrated searching/browsing mechanism employs user-constructed information hierarchies that represent a cognitive framework for the organization of information. The hierarchies are independent of the information itself. This feature permits them to be shared among multiple users, and applied to any of a variety of different sources of information. The hierarchical organization that is provided by the framework gives the user the ability to browse around any available document database in a manner that is intuitive to the user. Two or more hierarchies can be combined to locate documents which match the criteria of both hierarchies, and thereby refine search results to an appropriate level. A relevance feedback mechanism further enhances the browsing experience, by concentrating the search results in areas that are most relevant to documents selected as being of particular interest.

Claims

1. An information retrieval system, comprising:

a plurality of files stored in memory, each defining a different hierarchical relationship of terms describing an organizational framework for information;

a user interface that permits a user to select a level within each of at least two of the different hierarchical relationships;

a search query generator responsive to the selection of the level within each of the at least two different hierarchical relationships to construct a search query that is based upon terms associated with each of the selected levels, and to provide the query to a search engine to locate documents in a source of information which correspond to the search query; and

a display that displays information about the located documents to the user.

2. The information retrieval system of claim 1, wherein the search query contains the term at the selected level of each of the at least two hierarchical relationships and terms from lower levels of the hierarchical relationships that depend from the selected levels.

3. The information retrieval system of claim 2, wherein the terms are combined by boolean “

OR”

operators to form the search query.

4. The information retrieval system of claim 1, wherein the user interface permits the user to select one or more sources of information to be searched.

5. The information retrieval system of claim 1, wherein the display displays values which identify the relevance of a document to levels in the selected hierarchies, in accordance with information provided by the search engine that is based upon analysis of the document among the located documents to determine which of the terms in a hierarchy the document most closely relates to.

6. The information retrieval system of claim 5, wherein the user interface automatically selects a level within a hierarchy in accordance with the analysis of a selected document.

7. A method for locating documents within a source of information, comprising the steps of:

selecting, in a user interface of a computer, a level within each of at least two hierarchical relationships that define different respective organizational frameworks for information;

constructing, in a search query generator responsive to the selection of the level within each of the at least two hierarchical relationships, a search query that is based upon terms associated with each of the selected levels;

providing the search query to a search engine; and

displaying, on a display, information about the documents located by the search engine that correspond to the search query.

8. The method of claim 7, wherein the search query contains the term at the selected level of each of the at least two hierarchical relationships and terms from lower levels of the hierarchical relationships that depend from the selected levels.

9. The method of claim 8, wherein the terms are combined by boolean “

OR”

operators to form the search query.

10. The method of claim 8, further including the step of selecting one or more sources of information to be searched via the user interface.

11. The method of claim 8, further including the step of analyzing a selected document among the located documents to determine which of the terms in a hierarchy the selected document most closely relates to.

12. The method of claim 11, further including the step of displaying values which identify the relevance of the selected document to levels in a selected hierarchy.

13. The method of claim 12, further including the step of automatically selecting, in the user interface, a level within the hierarchy in accordance with the analysis of a selected document.
