20080228750 | "Query-log match" relevance features - Techniques for generating features that are used to rank documents in a search results page are provided. A query is received and may be modified before being compared to queries in a query log of previously-issued queries. The comparisons may be made in a variety of ways. The comparisons may allow query terms to be ordered and terms to be inserted. Relevance features are generated from the results of the comparisons. The documents that are referenced in a search results page (generated as a result of the query) are ranked based on the generated relevance features. | 09-18-2008 |
20090094196 | System and Method for Creating and Applying Predictive User Click Models to Predict a Target Page Associated with a Search Query - Systems and methods for predicting a target page associated with a search query are disclosed. Generally, a predictive user click model module defines a set of sessions and builds a model to predict whether a webpage is a target page associated with a search query based on a number of times, over the set of sessions, that a user as defined in the session clicks within the same session on a given webpage associated with a given search query versus a number of sessions in the set of sessions. | 04-09-2009 |
20090281970 | AUTOMATED TAGGING OF DOCUMENTS - An automated technique for tagging documents includes using a semantic tagger to generate an annotation that associates a standard tag with a first text fragment of the user-defined document, wherein the tagger is trained on a standard document annotated with a standard tag, associating the first user-defined tag with a second text fragment of the user-defined document in response to the second text fragment matching a value associated with the first user-defined tag, and establishing a mapping between the standard tag and the first user-defined tag in response to existence of a requisite correlation between the standard tag and the user-defined tag. The technique may further include selecting from the user-defined document a tagged text fragment that is associated with a second user-defined tag, and providing the tagged text fragment and a standard tag associated by the mapping with the second user-defined tag to the tagger as additional training input. | 11-12-2009 |
20100125575 | SEARCHING DOCUMENT COLLECTIONS USING SEMANTIC ROLES OF KEYWORDS - Methods and apparatus are described for facilitating discovery of information of interest in a document collection. A document model is proposed in which important terms and their semantic roles are represented. This document model is then used to facilitate searching and/or browsing of the document collection. | 05-20-2010 |
20100169339 | SYSTEM, METHOD, OR APPARATUS FOR UPDATING STORED SEARCH RESULT VALUES - Embodiments of methods, apparatuses, devices and systems associated with updating stored internet search query result values are disclosed. | 07-01-2010 |
20110173177 | SIGHTFUL CACHE: EFFICIENT INVALIDATION FOR SEARCH ENGINE CACHING - Updated queries are maintained in a cache. A search engine receives a query from a user through a query entry field. The search engine determines search results corresponding to the user query. A new entry mapping the user query to the search results is generated in a cache of results. A web crawler retrieves a new batch of documents for a particular document collection. A search index associated with a search engine is updated to reflect new documents in the document collection. A search engine of queries receives documents from the new batch of documents as inputs. Based on the received documents, the search engine of queries determines which of the queries would have returned the documents as relevant in a search. These queries are determined to be stale and invalidated. | 07-14-2011 |
20150074087 | System and Method for Retrieving Internet Pages Using Page Partitions - A system for and method for providing pages, more specifically a system includes a server configured to receive a query and an engine that is able to retrieve a set of pages by first retrieving a partition that contains them. | 03-12-2015 |
20150242393 | System and Method for Classifying Text Sentiment Classes Based on Past Examples - A passage sentiment classifier that can be used to assign a score that indicates the polarity and magnitude of sentiment expressed by a piece of text using information about similar passages. A passage of text may be a few words, a sentence, a paragraph or an entire document. The invention described classifies automatically passages by first looking up the most similarly classified passage in a storage system, which contains passages that have been classified manually by a human. | 08-27-2015 |
