International Classification:

G06F 7/00
G06F 17/30

US Classification:

707723, 707722, 707706

Abstract:

A unique system and method that facilitates improving the ranking of items is provided. The system and method involve re-ranking decreasing subsets of high ranked items in separate stages. In particular, a basic ranking component can rank a set of items. A subset of the top or high ranking items can be taken and used as a new training set to train a component for improving the ranking among these high ranked documents. This process can be repeated on an arbitrary number of successive high ranked subsets. Thus, high ranked items can be reordered in separate stages by focusing on the higher ranked items to facilitate placing the most relevant items at the top of a search results list.

International Classification:

G06F 17/30

US Classification:

707722

Abstract:

Systems, computer-implemented methods, and computer-readable media for modifying the rank of search result items returned by a search engine are provided. A search engine determines a plurality of search result items that satisfy a user query and the order the search result items are to be presented to a user. A rank modifier determines whether any modification should be made to the rank of each search result item identified by the search engine. The rank of search result items identified as potential spam may be demoted while the rank of search result items identified to be in the language of the search query, having a high click-through rate, or as containing adjacent search terms from the search query may be promoted. The search result items are presented according to modified ranking to the querying user.

US Classification:

709219

Abstract:

A system and method facilitating incremental web crawl(s) using chunk(s) is provided. The system can be employed, for example, to facilitate a web-crawling system that crawls (e. g. , continuously) the Internet for information (e. g. , data) and indexes the information so that it can be used as part of a web search engine. The system facilitates incremental re-crawls and/or selective updating of information (e. g. , documents) using a structure called a chunk to simplify the process of an incremental crawl. A chunk is a set of documents that can be manipulated as a set (e. g. , of up to 65,536 (64K) documents). “Document” refers to a corpus of data that is stored at a particular URL (e. g. , HTML, PDF, PS, PPT, XLS, and/or DOC Files etc. )A chunk is created by an indexer.
