The present invention pertains to the field of computer software. More specifically, the present invention relates to one or more of the definition, extraction, delivery, and hyper-linking of clips, for example web clips.

Method and apparatus for extraction

The present invention pertains to the field of computer software. More specifically, the present invention relates to one more populating, indexing, and searching a database of fine-grained web objects or object specifications.

Method and apparatus for searching network resources

The present invention relates to a method and apparatus for extracting relevant data. A first and a second set of data are accessed. The first set includes selected data. An edit sequence is determined between the first and the second sets, including considering at least repetitions for inclusion in the edit sequence. Corresponding data of the second set have a correspondence to the selected data are found at least partly by determining the edit sequence. A first and a second tree of data are accessed. The first tree includes selected data. An edit sequence is determined between the first and the second trees, including considering at least repetitions for inclusion in the edit sequence. Corresponding data of the second tree have a correspondence to the selected data are found at least partly by determining the edit sequence.

Method and apparatus for extracting relevant data

The present invention pertains to the field of computer software. More specifically, the present invention relates to dynamic discovery of documents or information through a focused crawler or search engine.

Method and apparatus for focused crawling

The present invention pertains to the field of computer software. More specifically, the present invention relates to populating, indexing, and searching a database of fine-grained web objects or object specifications. An embodiment of the invention is directed to a method of searching resources on the web. A query is received to search for information on the web and one or more web pages and one or more subsets of one or more web pages are accessed. The subsets have been extracted from one or more web pages prior to receiving the query. The subsets are extracted responsive to one or more views. The one or more views are defined independently of the search query. The views are content-sensitive filters that specify which subparts of a web page a user is interested in. Prior to receiving the search query, the subsets are stored in a database. Responsive to the search query, at least one or more of the extracted subsets of one or more web pages stored in the database is identified. The search query is used as a criterion for identifying at least one or more of the subsets.
