Patent number: 7359851Abstract: A method and system identifying the language of a textual passage is disclosed. The method and system includes parsing the textual passage into n-grams and assigning an initial weight to each n-gram, and adjusting the weight initially assigned to a word or n-gram parsed from the textual passage. The initially assigned weight is adjusted in a manner proportionate to the inverse of the number of languages within which such words or n-grams appear. Reducing the weight assigned to such words or n-grams diminishes—without completely eliminating—their importance in comparison to other words or n-grams parsed from the same textual passage when determining the language of a passage. The method and system of the present invention appropriately weighs the short words or n-grams common to multiple languages without affecting the short words or n-grams that are uncommon to several languages.Type: GrantFiled: January 14, 2004Date of Patent: April 15, 2008Assignee: Clairvoyance CorporationInventors: Xiang Tong, Gregory T. Grefenstette, David A. Evans

Patent number: 7284191Abstract: A personality that identifies enrichment themes of a document is associated with a reading or mobile computing device. In one embodiment, a personality is associated with a document reference reading device and attached to each document reference recorded by the document reference reading device. The personality and each recorded document reference are transmitted to a meta-document server. The meta-document server enriches document content identified by the document reference in accordance with the associated personality. The enriched document content is then made available to the user of the reading device.Type: GrantFiled: December 5, 2001Date of Patent: October 16, 2007Assignee: Xerox CorporationInventors: Gregory T Grefenstette, James G. Shanahan

Patent number: 7117432Abstract: In a document enrichment system, device buttons can be programmed to associate a number of personalities to the buttons on the device. These associations may be stored locally on the device. When the device with the programmed personality is activated on the device, the document produced is sent to a document enrichment system. Once enriched the document enrichment system notifies the user of the availability of the document in its new form.Type: GrantFiled: December 5, 2001Date of Patent: October 3, 2006Assignee: Xerox CorporationInventors: James G. Shanahan, Gregory T Grefenstette

Patent number: 6928425Abstract: A system provides a plurality of controls for enriching the content of a meta-document. A meta-document includes document content and personalities that describe enrichment themes. The system is adapted to automatically, with user settable constrains, determine whether to propagate enrichment between documents using an interaction history. In addition, the system is adapted to automatically determine, with user settable constraints, the form that markup is to take in the document content.Type: GrantFiled: December 5, 2001Date of Patent: August 9, 2005Assignee: Xerox CorporationInventors: Gregory T. Grefenstette, James G. Shanahan

Patent number: 6820075Abstract: An information space is created using a document. Entities from the document and its information space are used to create a database of entities. An auto-completion system uses contextual information surrounding a fragment from the document to formulate a query. The query is used to identify a set of entities in the database of entities that complete the fragment. An auto-correction system uses contextual information from identified errors in the document to formulate a query. The query is used to identify a set of entities in the database of entities that correct the error.Type: GrantFiled: December 5, 2001Date of Patent: November 16, 2004Assignee: Xerox CorporationInventors: James G. Shanahan, Gregory T. Grefenstette

Patent number: 6778979Abstract: A system generates a query using an entity extractor, a categorizer, a query generator, and a short run aspect vector. The entity extractor identifies a set of entities in selected document content for searching information related thereto using an information retrieval system. The categorizer defines an organized classification of document content with each class in the organization of content having associated therewith a classification label that corresponds to a category of information in the information retrieval system. The categorizer assigns the selected document content a classification label from the organized classification of content. A query generator formulates a query that restricts a search at the information retrieval system to the category of information in the information retrieval system identified by the assigned classification label.Type: GrantFiled: December 5, 2001Date of Patent: August 17, 2004Assignee: Xerox CorporationInventors: Gregory T. Grefenstette, James G. Shanahan

Patent number: 6732090Abstract: A system operates using meta-documents which include document content associated with one or more personalities. Each personality is associated with a set of document service requests. Users are provided different techniques for creating personalities and modifying existing personalities. These techniques include: the use of an algebra to tailor existing personalities, the use of a list of links or documents to create a personality, the use of predefined personalities and knowledge levels in a field to create new personalities, the use of question answering techniques, and the use of learning personalities. Specified personalities are then used to enrich document content by integrating into corresponding meta-documents the results received from their document service requests.Type: GrantFiled: December 5, 2001Date of Patent: May 4, 2004Assignee: Xerox CorporationInventors: James G. Shanahan, Gregory T. Grefenstette, Christer Fernstrom, Laurence Hubert
