Patent number: 10984385Abstract: In an example embodiment, one or more specified ideal candidates are used to perform a search in a database. One or more attributes are extracted from one or more ideal candidate member profiles. A search query is then generated based on the extracted one or more attributes. Then, a search is performed on member profiles in the social networking service using the generated search query, returning one or more result member profiles.Type: GrantFiled: May 31, 2016Date of Patent: April 20, 2021Assignee: Microsoft Technology Licensing, LLCInventors: Ye Xu, Viet Thuc Ha, Xianren Wu, Satya Pradeep Kanduri, Vijay Dialani, Yan Yan, Abhishek Gupta, Shakti Dhirendraji Sinha

Patent number: 10726084Abstract: In an example embodiment, usage information is used to calculate one or more individual document historical information-deficient metrics (IDHIDMs) by combining values for the one or more metrics from multiple documents within the document corpus that share an identical combination of entities of the one or more entity types. A search query is segmented into a plurality of segments, wherein at least one of the plurality of segments is tagged as a first entity type and at least one of the plurality of segments is tagged as a second entity type. At least one for a combination of entities matching the tagged segments is used to rank one or more retrieved documents responsive to the query.Type: GrantFiled: December 18, 2015Date of Patent: July 28, 2020Assignee: Microsoft Technology Licensing, LLCInventors: Jia Li, Dhruv Arya, Shakti Dhirendraji Sinha, Viet Thuc Ha, Deepak Agarwal

Patent number: 10606847Abstract: In an example embodiment, one or more sample ideal candidate member profiles in a social networking service are obtained, as well as one or more sample search result member profiles in the social networking service. Then, for each unique pair of sample ideal candidate member profile and sample search result member profile, a label is generated using a score generated from log information of the social networking service, the log information including records of communications between a searcher and members of the social networking service, the score being higher if the searcher communicated with both the member corresponding sample ideal candidate member profile and the member corresponding to the sample search result member profile in a same search session. The generated labels are fed into a machine learning algorithm to train a combined ranking model used to output ranking scores for search result member profiles.Type: GrantFiled: May 31, 2016Date of Patent: March 31, 2020Assignee: Microsoft Technology Licensing, LLCInventors: Yan Yan, Viet Thuc Ha, Xianren Wu, Satya Pradeep Kanduri, Vijay Dialani, Ye Xu, Abhishek Gupta, Shakti Dhirendraji Sinha

Patent number: 10380553Abstract: In an example, a plurality of member profiles in a social networking service are obtained, each member profile identifying a member and listing one or more skills the corresponding member has explicitly added to the member profile, the one or more skills indicating a proficiency by the member in the corresponding skill. A members-skills matrix is formed, wherein each cell in the matrix is assigned a value based on whether the corresponding member has the corresponding skill. The dot product of the members matrix and the skills matrix is then computed and used to identify one or more latent skills of a first member of the social networking service. Then a first digitally stored member profile is augmented with the one or more latent skills by combining the one or more latent skills with explicit skills for purposes of one or more searches that utilize member skills as an input variable.Type: GrantFiled: April 14, 2017Date of Patent: August 13, 2019Assignee: Microsoft Technology Licensing, LLCInventors: Jia Li, Dhruv Arya, Shakti Dhirendraji Sinha, Viet Thuc Ha, Deepak Agarwal

Patent number: 10373075Abstract: In an example embodiment, a query for search results is received, the query including at least one value for one facet, a facet defining a categorical dimension for the search results. It is then determined that the facet in the query is exclusive. In response to the determination that the facet is exclusive: for each potential facet different from the facet in the query: for each potential value in the potential facet: conditional entropy gain of the value in the query and the potential value is determined. The potential value in the potential facet that has the highest conditional entropy gain is determined, as is the potential facet with the minimum maximum conditional entropy gain. Then the potential facet with the minimum maximum is input into a machine learning model, causing the machine learning model to output one or more suggested facets to add to the query.Type: GrantFiled: June 21, 2016Date of Patent: August 6, 2019Assignee: Microsoft Technology Licensing, LLCInventors: Xianren Wu, Satya Pradeep Kanduri, Vijay Dialani, Ye Xu, Yan Yan, Viet Thuc Ha, Abhishek Gupta, Shakti Dhirendraji Sinha

Publication number: 20160314477Abstract: A system, method, and apparatus are provided for identifying entities trending within a professional community, such as member of a professional social network. The system collects “share” activity and/or other types of activities conducted by members of the community in which they generate or disseminate (textual) content. From the collected share activity, trending terms are identified and ranked according to scores that reflect the change in frequency of usage of the terms over time. The most relevant shares for each trending term are identified and used to identify names of entities that correspond to (e.g., include) the terms. Reasons indicating why each trending entity is trending are also derived from the share activity. A display or presentation is provided of top trending entities, within one or more segments of the professional community, which includes the reasons and allows a viewer to quickly identify the reason a given entity is trending.Type: ApplicationFiled: April 27, 2015Publication date: October 27, 2016Applicant: LinkedIn CorporationInventor: Viet Thuc Ha
