Abstract
A system, computer readable medium and method for searching for recently altered documents on the World Wide Web is provided. The method selects a server to be searched or crawled by a Web crawler based on a user selected ranking. Servers are ranked by a filter program which compares a user query with the content of a server and the frequency in which content is altered. A top percentage of ranked servers are crawled and the recently altered information, such as hyperlinks, are then provided to the user.
Claims24
System for monitoring the World Wide Web (WWW), comprising:
- a user interface coupled to the WWW operable to obtain user information, wherein the user information includes a query;
- a ranking component operable to rank a set of servers wherein each one of the set of servers is coupled to the WWW and wherein the ranking is based on at least one of:
- 1) a comparison of content on each server with the query;
- and 2) a frequency at which content on each server is altered;
- and
- a search engine coupled to the WWW including a Web crawler operable to search at least one of the ranked servers in order of rank based on the query and generate search results wherein the search results refer to content on ranked servers that satisfy the query.
A method adapted for obtaining information from the World Wide Web (WWW) comprising the steps of:
- obtaining a query;
- calculating a content score of a first document having a first address on the WWW wherein the content score is based on comparing a content vector for the first document with the query;
- ranking the first document in a set of documents based on at least one of:
- 1) the content score;
- and 2) a frequency at which document content is altered;
- selecting a highest ranked document from the set of documents;
- and
- crawling a first processing device on which the highest ranked document is stored to obtain a first altered document.
A machine readable medium having instructions stored thereon that when executed by a processor cause a system to:
- obtain a query;
- calculate a content score of a first document having a first address on the World Wide Web (WWW) wherein the content score is based on comparing a content vector for the first document with the query;
- rank the first document in a set of documents based on at least one of:
- 1) the content score;
- and 2) a frequency at which content on the document is altered;
- select the highest ranked document from the set of documents;
- and
- crawl a first processing device on which the highest ranked document is stored to obtain a first altered document.
