Abstract

A system and method for searching sources of data such as the World Wide Web for things such as available products and services, utilizing indexing of documents therein such as web pages and sites through automatic categorization based on their type, such as whether or not they offer products and/or services.

Claims

1. A method of searching a data source utilizing automatic categorization, comprising the following steps:

a) applying an automatic categorization algorithm to a plurality of documents in the data source;

b) storing categorization information resulting from step a) in a category index;

c) receiving a user query from a user;

d) causing one or more searching means to execute said user query on part or all of the data source so as to identify and return a list of some or all documents therein that satisfy said user query;

e) checking said list of some or all documents returned in step d) against said categorization information stored in said category index;

f) manipulating said list of documents based on information derived from said checking; and

,

g) returning to said user a manipulated list of documents.

2. The method of claim 1, wherein said step of manipulating includes limiting said list of step d) to exclude documents that do not fall within one or more selected categories.

3. The method of claim 1, wherein said step of manipulating includes the step of ordering said list of step d) into one or more selected categories.

4. The method of claim 1, wherein said step of manipulating includes the step of marking up entries in said list of step d) according to their categories.

5. The method of claim 1, further comprising the step of providing said user with further information relating to said manipulated list of documents.

6. The method of claim 1, wherein step e) is performed on a computing means separate and remote from the computing means on which said one or more searching means are hosted.

7. The method of claim 1, wherein step e) is performed as part of step d) and said category index is integrated into a searching means'"'"' global index.

8. The method of claim 1, wherein step a) categorizes said documents according to whether or not they fall into a predefined “

shopping”

category.

9. The method of claim 8, wherein said predefined “

shopping”

category is limited to documents that offer products.

10. The method of claim 1, wherein at least one of said one or more searching means is a web search engine, and said documents are web pages.

11. The method of claim 10, further comprising the steps of, after steps a) and b) have been performed at least once, performing steps a) and b) on any web pages returned in step d) that are not represented in said category index.

12. The method of claim 1, further comprising the steps of, after steps a) and b) have been performed at least once, performing steps a) and b) on any documents returned in step d) that are not represented in said category index.

13. A system for searching a data source utilizing automatic categorization, comprising:

a) automatic categorization means for categorizing a plurality of documents in the data source;

b) a category index that contains categorization information received from said automatic categorization means;

c) means for receiving a user query from a user;

d) means for causing one or more searching means to execute said user query on part or all of the data source so as to identify and return a list of some or all documents therein that satisfy said user query;

e) means for checking said list of some or all documents returned by said searching means against said categorization information contained in said category index;

f) means for manipulating said list of documents based on information derived from said checking means; and

,

g) means for returning to said user a manipulated list of documents.

14. The system of claim 13, wherein said means for manipulating include means for excluding documents not meeting one or more selected categories.

15. The system of claim 13, wherein said means for manipulating include means for ordering results by category.

16. The system of claim 13, wherein said step of manipulating includes the step of marking up entries in said list of step d) according to their categories.

17. The system of claim 13, further comprising means for providing said user with further information relating to said manipulated list of documents.

18. The system of claim 13, wherein said system is hosted on computing means separate and remote from those hosting said one or more searching means.

19. The system of claim 13, wherein said system is hosted on computing means that hosts at least one of said one or more searching means, and said category index is integrated into that at least one searching means'"'"' global index.

20. The system of claim 13, wherein said automatic categorization means is adapted to categorize documents according to whether or not they fall into a predefined “

shopping”

category.

21. The system of claim 20, wherein said predefined “

shopping”

category is limited to documents that offer products.

22. The system of claim 13, wherein at least one of said one or more searching means is a web search engine, and said documents are web pages.

23. The system of claim 22, further comprising means for updating said category index in response to the return by said web search engine of any web pages identified that were not previously represented in said category index.

24. The system of claim 13, further comprising means for updating said category index in response to the return by said searching means of any documents identified that were not previously represented in said category index.
