Publication number: 20150324449Abstract: Methods, systems, and techniques for cluster-based content recommendation are described. Some embodiments provide a content recommendation system (“CRS”) configured to recommend news stories about events or occurrences. In some embodiments, a news story about an event includes multiple related content items that each include an account of the event and that each reference one or more entities or categories that are represented by the CRS. In one embodiment, the CRS identifies news stories by generating clusters of related content items. Then, in response to a received query that indicates a keyterm, entity, or category, the CRS determines and provides indications of one or more news stories that are relevant to the received query. In some embodiments, at least some of these techniques are employed to implement a news story recommendation facility in an online news service.Type: ApplicationFiled: July 16, 2015Publication date: November 12, 2015Inventors: Krzysztof Koperski, Satish Bhatti, Jisheng Liang, Adrian Klein

Publication number: 20150317301Abstract: Techniques for providing quotations obtained from text documents using natural language processing techniques are described. Some embodiments provide a content recommendation system (“CRS”) configured to provide quotations by extracting quotations from a corpus text documents, and providing access to the extracted quotations in response to search requests received from users. The CRS may extract quotations by using natural language processing-based techniques to identify one or more entities, such as people, places, objects, concepts, or the like, that are referenced by the extracted quotations. The CRS may then store the extracted quotations along with identified entities, such as quotation speakers and subjects, for later access via search requests.Type: ApplicationFiled: June 23, 2015Publication date: November 5, 2015Inventors: Jisheng Liang, Navdeep S. Dhillon, Krzysztof Koperski

Publication number: 20150310104Abstract: Methods and systems for extending keyword searching techniques to syntactically and semantically annotated data are provided. Example embodiments provide a Syntactic Query Engine (“SQE”) that parses, indexes, and stores a data set as an enhanced document index with document terms as well as information pertaining to the grammatical roles of the terms and ontological and other semantic information. In one embodiment, the enhanced document index is a form of term-clause index, that indexes terms and syntactic and semantic annotations at the clause level. The enhanced document index permits the use of a traditional keyword search engine to process relationship queries as well as to process standard document level keyword searches. This abstract is provided to comply with rules requiring an abstract, and it is submitted with the intention that it will not be used to interpret or limit the scope or meaning of the claims.Type: ApplicationFiled: September 5, 2014Publication date: October 29, 2015Inventors: Giovanni B. Marchisio, Navdeep S. Dhillon, Carsten Tusk, Krzysztof Koperski, Jisheng Liang, Thien Nguyen, Matthew E. Brown

Publication number: 20140229467Abstract: Methods, techniques, and systems for using natural language processing to recommend related content to an associated text segment or document. Example embodiments provide a NLP-based content recommender (“NCR”) which uses NLP-based search techniques, potentially in conjunction with context or other related information, to locate and provide content related to entities that are recognized in the associated material. NCRs may be embedded as widgets, for example on Web pages to assist users in their perusal and search for information, provided by means of browser plug-ins or other application plug-ins, provided in libraries or in standalone environments, or otherwise integrated into other code, programs, or devices. This abstract is provided to comply with rules requiring an abstract, and it is submitted with the intention that it will not be used to interpret or limit the scope or meaning of the claims.Type: ApplicationFiled: February 14, 2014Publication date: August 14, 2014Applicant: Vulcan Inc.Inventors: Neil Roseman, Jisheng Liang, Krzysztof Koperski, Korina J.

Publication number: 20140214850Abstract: Techniques for category-based content recommendation are described. Some embodiments provide a content recommendation system (“CRS”) configured to recommend content items (e.g., Web pages, images, videos) that are related to specified categories. In one embodiment, the CRS processes content items to determine entities referenced by the content items, and to determine categories related to the referenced entities. The determined entities and/or categories may be part of a taxonomy that is stored by the CRS. Then, in response to a received request that indicates a category, the CRS determines and provides indications of one or more content items that each have a corresponding category that matches the indicated category. In some embodiments, at least some of these techniques are employed to implement a category-based news service.Type: ApplicationFiled: March 31, 2014Publication date: July 31, 2014Applicant: VCVC III LLCInventors: Jisheng Liang, Krzysztof Koperski, Jennifer Cooper, Ted Diamond

Publication number: 20140181096Abstract: Systems, methods, and computer-readable storage media for disambiguating entity names by determining query terms to associate with certain entities based on, for instance, user selection of Uniform Resource Locators (URLs), are provided. In embodiments, query data is analyzed to determine which queries are most closely associated with certain entities, based on quantities of user selections associated with a particular URL and a given query, as compared to a total quantity of user selections associated with the query. Identified queries can be used to return search results, images to supplement search results, advertising, or the like that are associated with appropriate entities.Type: ApplicationFiled: December 21, 2012Publication date: June 26, 2014Applicant: Microsoft CorporationInventors: Wei Zhuang, Jisheng Liang

Publication number: 20140149383Abstract: Enhanced computer- and network-based methods, systems, techniques are provided for retrieving more accurate and responsive search results when searching content for a designated entity using an off-the-shelf keyword-based search engine. For example, the embodiments described herein may be used to improve search results by eliminating off-topic results when presenting queries to an existing keyword-based search engine invoked by means of an API from an intermediating application. Example embodiments provide a Keyword-Based Search Enhancement System (“KBSES”), which enables intermediating applications to obtain information more closely related to user queries by enhancing such queries, on behalf of the user, with disambiguating information when deemed necessary.Type: ApplicationFiled: January 31, 2014Publication date: May 29, 2014Applicant: Vulcan Inc.Inventors: Ted Diamond, Jisheng Liang, Jonathan Reichhold, Krzysztof Koperski

Publication number: 20140142922Abstract: Methods and systems for entity recognition and disambiguation using natural language processing techniques are provided. Example embodiments provide an entity recognition and disambiguation system (ERDS) and process that, based upon input of a text segment, automatically determines which entities are being referred to by the text using both natural language processing techniques and analysis of information gleaned from contextual data in the surrounding text. In at least some embodiments, supplemental or related information that can be used to assist in the recognition and/or disambiguation process can be retrieved from knowledge repositories such as an ontology knowledge base. In one embodiment, the ERDS comprises a linguistic analysis engine, a knowledge analysis engine, and a disambiguation engine that cooperate to identify candidate entities from a knowledge repository and determine which of the candidates best matches the one or more detected entities in a text segment using context information.Type: ApplicationFiled: July 17, 2013Publication date: May 22, 2014Inventors: Jisheng Liang, Krzysztof Koperski, Navdeep S.
