Patent number: 8660857Abstract: A recommendation system and method includes extracting patient features for a current patient to generate representation of the current patient. The patient features for the current patient are compared to physician features of one or more physicians and patient-to-physician features of a group of patients from medically related records. Outcome measures associated with physicians are compared related to a current query. A future outcome for patient, physician pairs are predicted for the current patient based upon at least one predictive model constructed from the features and outcome measures to output.Type: GrantFiled: October 27, 2010Date of Patent: February 25, 2014Assignee: International Business Machines CorporationInventors: Shahram Ebadollahi, Jianying Hu, Martin S.

Patent number: 8538955Abstract: In a computerized social network, expert and user chat sessions are stored and rated probabilistically. Later user requests for information are met with an expert ranking, based on a balance of similarities between expert profile and questions; similarity between expert profile and prior chat sessions, and dynamically updated chat session ratings. New sessions can be rated automatically with reference to keywords distilled from past sessions responsive to user ratings—and based on session length.Type: GrantFiled: August 22, 2012Date of Patent: September 17, 2013Assignee: International Business Machines CorporationInventors: Jianying Hu, Jennifer Lai, Aleksandra Mojsilovic, Vikas Sindhwani, Kevin Singley

Publication number: 20130231953Abstract: A system, method and program product for matching members of a population, e.g., patients, based on member similarities. Patients are mapped to a bipartite graph with patient nodes connected by weighted edges to clustered factor nodes, are clustered categorically. As a new patient query is received, a similarity measure for each other patient is generated for each cluster by comparing cluster edges. The cluster similarity measures are aggregated for each patient to provide a global closeness measure to every other patient. Based on the global closeness measure, a list of the closest patients is displayed and measurement feedback may be provided.Type: ApplicationFiled: March 1, 2012Publication date: September 5, 2013Inventors: Shahram Ebadollahi, Jianying HU, Jimeng Sun, Robert K.
