Filed:

Feb 7, 1997

Appl. No.:

08/797630

Inventors:

Jacek R. Ambroziak - Acton MA

Assignee:

Sun Microsystems, Inc. - Palo Alto CA

International Classification:

G06F 1516

US Classification:

709219, 707513, 707103

Abstract:

Network browsing is facilitated by receiving a document from the network containing content; extracting conceptual information from the content of the document; analyzing the extracted conceptual information semantically; and assimilating the extracted conceptual information into an index based on structural relationships among the extracted conceptual information and semantic data in a stored lexicon.

Appl. No.:

09/535632

Inventors:

Jacek Ambroziak - Acton MA

Assignee:

Sun Microsystems, Inc. - Palo Alto CA

International Classification:

G06F 1730

US Classification:

707102

Abstract:

A technique for indexing data is provided. A method for compressing an index to obtain a compressed index that is easily stored and transmitted is provided. The invention also provides for the decompression of such a compressed index. One embodiment of the invention maintains a separate index for each document, thereby allowing easy updating of indexes in response to changes in documents and easy transmission of indexes, which allows distributed searching. The technique provides very compact indexing information, but allows the indexing information to be very rapidly processed.

Appl. No.:

09/513439

Inventors:

Jacek R. Ambroziak - Acton MA

Assignee:

Sun Microsystems, Inc. - Santa Clara CA

International Classification:

G06F 1500

US Classification:

715530, 715513, 7155011

Abstract:

One embodiment of the present invention provides a system that generates an index to facilitate searching through text within a document based upon an index stylesheet associated with the document. The system operates by receiving a document to be indexed and then parses the document to produce a parsed document. The system also retrieves instructions for creating the index for the document from an index stylesheet associated with the document. The system creates the index for the document by transforming the parsed document in a manner that is specified by the instructions retrieved from the index stylesheet. In one embodiment of the present invention, retrieving the index stylesheet involves retrieving the index stylesheet across a network from a remote address.
