Abstract

A search system and method for searching for electronic documents, and providing a search result in response to a search query. In one embodiment, the search system includes a processor, a user interface module adapted to receive a search query from a user that includes a search query term, a search engine that electronically searches for electronic documents that satisfy the search query term, and a query processing module that identifies at least one alternative term for the search query term, and provides the alternative term to the user interface module for display to the user, and also provides the alternative term to the search engine to search for electronic documents that satisfy the alternative term.

Claims

1. A search system for searching for electronic documents, and providing a search result in response to a search query, comprising:

a processor;

a database, wherein terms in the database are grouped in a cluster based on the terms belonging to a same word sense;

a user interface module adapted to receive a search query from a user, said search query having at least one search query term;

a query processing module that determines a word sense for the at least one search query term, and wherein said user interface module is adapted to display alternative senses in which said search query term is used, and to allow the user to select at least one of the alternative word senses, and wherein the query processing module identifies a plurality of any available alternative terms from a cluster based on the sense selected by the user;

a search engine that electronically searches for electronic documents that satisfy said at least one search query term and said plurality of any available alternative terms; and

wherein said user interface module is further adapted to display search results received from the search engine.

2. The search system of claim 1, wherein said search engine executes a search based on said search query term and said plurality of any available alternative terms simultaneously.

3. The search system of claim 2, wherein said user interface only displays said search results that satisfy at least one search query term and ranks said search results based at least in part on whether said search results satisfy said any available alternative terms.

4. The search system of claim 2, wherein said user interface progressively displays said search results.

5. The search system of claim 1, wherein said cluster is a collection of words grouped together based on having similar usage patterns.

6. The search system of claim 1, wherein said user interface module is adapted to display alternative domain categories in which said search query term is used, and to allow user selection of the domain category.

7. The search system of claim 1, wherein said user interface module is adapted to display a part-of-speech in which said search query term is presumed to be used.

8. The search system of claim 7, wherein said user interface module is adapted to display an alternative part-of-speech in which said search query term is used, and to allow user selection of the part-of-speech.

9. A computer implemented search method for electronically searching documents, and providing a search result in response to a search query, comprising:

receiving, using a user interface module controlled by a computer processor, a search query from a user, said search query having at least one search query term;

electronically determining, using a query processing module controlled by a computer processor, a sense of said at least one search query;

displaying alternative senses in which said at least one search query term is used, and receiving the user'"'"'s selection of at least one the alternative senses;

electronically identifying, using the query processing module controlled by a computer processor, a plurality of available alternative terms from a cluster of terms belonging to a same word sense for the at least one search query term based on the user'"'"'s selected alternative sense; and

electronically executing a search, using a search engine, for electronic documents that satisfy at least one of said search query term and the plurality of available alternative terms.

10. The search method of claim 9, further including executing the search based on said search query term and said plurality of available alternative terms simultaneously.

11. The search method of claim 9, further comprising displaying alternative domain categories in which said at least one search query term is used, and receiving user'"'"'s selection of at least one alternative domain category.

12. The search method of claim 11, further including displaying for the user, a part-of-speech in which said at least one search query term is presumed to be used.

13. The search method of claim 12, further including displaying alternative parts-of-speech in which said at least one search query term is used, and receiving user'"'"'s selection of at least one of the alternative part-of-speech.

14. A computer readable hardware medium with executable instructions stored thereon, which when executed by a computer processor, cause said computer to execute a method for searching for electronic documents, and providing a search result in response to a search query, the method comprising:

receiving a search query from a user, said search query having at least one search query term;

electronically determining a sense of said at least one search query term;

displaying alternative senses in which said at least one search query term is used, and receiving the user'"'"'s selection of at least one of the alternative senses;

electronically identifying a plurality of available alternative terms from a cluster of terms belonging to a same word sense for the at least one search query term based on the user'"'"'s selection of the at least one alternative sense; and

electronically executing a search for electronic documents that satisfy at least one of said search query term and the plurality of alternative terms.

15. The computer readable medium of claim 14, further comprising executing the search based on said search query term and said plurality of available alternative terms simultaneously.

16. The computer readable medium of claim 14, further comprising displaying alternative domain categories in which said at least one search query term is used, and receiving the user'"'"'s selection of at least one alternative domain category.

17. The computer readable medium of claim 14, further comprising displaying for the user, a part-of-speech in which said at least one search query term is presumed to be used.

18. The computer readable medium of claim 17, further comprising displaying alternative parts-of-speech in which said at least one search query term is used, and for receiving user'"'"'s selection of at least one of the alternative part-of-speech.

19. A search system for searching for electronic documents, and providing a search result in response to a search query, comprising:

a processor;

a database, wherein terms in the database are grouped in a cluster based on the terms belonging to a same word sense;

a user interface module adapted to receive a search query from a user, said search query having at least one search query term;

a query processing module that determines a domain category for the at least one search query term, and wherein said user interface module is adapted to display alternative domain categories in which said search query term is used, and to allow the user to select at least one of the alternative domain categories, and wherein the query processing module identifies a plurality of any available alternative terms from a cluster based on the domain category selected by the user;

a search engine that electronically searches for electronic documents that satisfy said at least one search query term and said plurality of available alternative terms; and

wherein said user interface module is further adapted to display search results received from the search engine.

20. The search system of claim 19, wherein said search engine executes a search based on said search query term and said plurality of available alternative terms simultaneously.

21. The search system of claim 19, wherein said query processing module retrieves said plurality of available alternative terms from said database.
