Abstract

The system of the present invention provides for a method and apparatus of displaying portions of text from multiple documents over multiple databases related to a search query. The initial step in this method is to identify a search query. Based on this identification, a search against multiple databases is initiated. In particular, the computer system identifies auxiliary databases either within a network or between networks that are likely to contain documents relating to terms in the search query. Upon identification of these databases, the databases are then searched to identify those documents relating to the identified query. The various sets of identified documents from multiple databases are then returned and processed to create an ordered ranking for the returned documents. Text portions from the highest ranking documents across the multiple databases are then automatically displayed to the user.

Claims

1. A method for automatically displaying text from a database related to a query, comprising:

generating a query by selecting a region of text from a document;

automatically selecting a plurality of databases related to said query;

automatically searching at least one database for documents related to said query;

organizing documents returned from said search in a relevance order corresponding to the relevance of said returned documents to said query; and

displaying portions of test related to said query from a plurality of said returned documents in said relevance order.

2. A method for automatically displaying text from a database related to a query, as in claim 1, wherein:

said document incorporating said selected region of text is stored in a database that is not related to said query.

3. A method for automatically displaying text from a database related to a query, as in claim 1, wherein:

said organization of said returned documents computes a relevance score for said returned documents and rank orders the returned documents according to said relevance score.

4. A method for automatically displaying text from a database related to a query, as in claim 1, wherein:

said automatic searching of the selected database compares document text of said selected database to boolean combinations of keywords.

5. A method for automatically displaying text from a database related to a query, as in claim 4, wherein:

said organization of said returned documents computes a relevance score for said returned documents and rank orders the returned documents according to said relevance score.

6. A system for displaying text from a database related to a query, comprising:

a computer coupled to an input/output device for generating a query, said query is generated by selecting a region of text from a document;

said computer coupled to a disk storage unit, said computer selects a plurality of databases related to said query, wherein said databases are identified by address in said disk storage unit;

said computer automatically searches at least one database for documents related to said query;

said computer organizes documents returned from said search in a relevance order corresponding to the relevance of said returned documents to said query; and

said computer coupled to a display unit for displaying portions of text related to said query from a plurality of said returned documents in said relevance order.

7. A system for displaying text from a database related to a query, as in claim 6, wherein:

said document incorporating said selected region of text is stored in a database that is not related to said query.

8. A system for displaying text from a database related to a query, as in claim 6, wherein:

said organization of said returned documents computes a relevance score for said returned documents and rank orders the returned documents according to said relevance score.

9. A system for displaying text from a database related to a query, as in claim 6, wherein:

said automatic searching of the selected database compares document text of said selected database to boolean combinations of keywords.

10. A system for displaying text from a database related to a query, as in claim 9, wherein:

said organization of said returned documents computes a relevance score for said returned documents and rank orders the returned documents according to said relevance score.
