Abstract

A method provides a more informative result to a user in connection with the search for documents in a database. In particular, the method provides augmented addresses, in the Internet environment augmented universal resource locators, which include an indication of a document attribute which may be of interest to the user. Such attributes may include an indication of the language of the document (e.g., English or Japanese) or the popularity of the document.

Claims

1. A method for providing more informative results in response to a search of electronic documents in an unstructured database, where each document has a document address associated therewith, the method comprising the steps of:

storing a first attribute in a parameter field associated with a document address of an electronic document;

receiving a search request including a desired attribute;

for each of a plurality of electronic documents comparing said desired attribute to said first attribute in the parameter field for that document; and

presenting, as a search result, the document address of an electronic document having a first attribute matching said desired attribute.

2. The method of claim 1 wherein said first attribute identifies the language of the associated document.

3. The method of claim 1 wherein said first attribute identifies a geographic location of a source for the associated document.

4. The method of claim 1 wherein said first attribute defines a relative popularity of the corresponding document.

5. In an unstructured database, a method for identifying an electronic document in response to a search request, the method comprising the steps of:

augmenting an address of an electronic document to reflect an attribute of that document;

determining a plurality of electronic documents to be responsive to a given search request; and

presenting as a search result the augmented address for each document having an augmented address that is identified to be responsive to the search request.

6. The method of claim 5 wherein said attribute of the augmented address reflects a geographic location of the source of the corresponding identified document.

7. The method of claim 5 wherein said attribute of the augmented address reflects a language of the corresponding identified document.

8. The method of claim 5 wherein said attribute of the augmented address reflects a relative popularity of the corresponding identified document.

9. The method of claim 8 wherein said attribute of the augmented address identifies the number of other documents providing links to the corresponding identified documents.

10. The method of claim 8 wherein said relative popularity of a given document is defined in terms of the number of times the document has been identified as a result of a search over a predetermined time interval.

11. A method for searching for electronic documents in an unstructured database, the method comprising the steps of:

receiving a search query including a keyword and a document attribute;

for each of a plurality of documents, determining whether the document includes said keyword and whether the document satisfies the document attribute; and

presenting as a search result, a document address of each document that is found to satisfy the search query during said steps of determining.

12. The method of claim 11 wherein said document address constitutes a universal resource locator (URL).

13. The method of claim 12 wherein said result includes an augmented URL for each document that is found to satisfy the search query, said augmented URL including a URL of the document and an attribute of the document.

14. The method of claim 11 wherein said step of presenting includes providing an attribute of the document that is found to satisfy the search query.

15. The method of claim 14 wherein the attribute presented in said step of presenting differs from said attribute in said search query.
