Publication number: 20160358097Abstract: Embodiments of the present invention provide a method for detecting a temporal change of name associated with performance data. The method comprises receiving at least one candidate name replacement pair comprising a pair of names. The method further comprises, in a training stage, for each known name replacement pair included in the performance data, determining a window of time covering a most recent appearance of a first name of the known name replacement pair. The window of time is determined based on quantitative features of a time series model comprising performance data for the first name and a second name of the known name replacement pair. The method further comprises, in the training stage, training a machine learning classifier based on quantitative features computed using a portion of the performance data for the first name and the second name, where the portion is within the window of time determined.Type: ApplicationFiled: June 2, 2015Publication date: December 8, 2016Inventors: Jeanette L.

Publication number: 20150235239Abstract: Predicting demand of a newly launched product may comprise obtaining customer sentiment data associated with the newly launched product, the customer sentiment data obtained at least from social media. A mean sentiment lag associated with the customer sentiment data may be determined. A weight given to a predicted PLC effect of the newly launched product relative to customer sentiment identified in the customer sentiment data may be determined. Numerical prediction parameters from parameter values associated with a like-item that is determined to be similar to the newly launched product may be obtained. A product utility valuation may be computed as a weighted combination of the predicted PLC effect and a lagged social media sentiment determined from the customer sentiment data accounted by the mean sentiment lag. The product utility valuation provides an indication of the future demand of the newly launched product.Type: ApplicationFiled: February 19, 2014Publication date: August 20, 2015Applicant: INTERNATIONAL BUSINESS MACHINES CORPORATIONInventors: Pawan R.

Publication number: 20140310064Abstract: A top-down and bottom-up approach that decomposes product bundles to components, classifies them into different groups corresponding to a component similarity measure, and detects their inherent values. The bundles are reassembled and characterized by several key attributes according to their component inherent values, and classified into segments. A normalized utility model is constructed for each product bundle segment, taking into account the additive effect among different commodity types and product families. The goodness of fit of the top-down and the bottom-up model may be validated. The model may be applied in an RFQ pricing environment.Type: ApplicationFiled: April 16, 2013Publication date: October 16, 2014Applicant: International Business Machines CorporationInventors: Pawan R. Chowdhary, Markus R. Ettl, Shivaram Subramanian, Zizhuo Wang, Zhengliang Xue

Patent number: 8671084Abstract: A method, information processing system, and computer readable medium for modifying at least one data warehouse schema based on detected changes in an associated observation model are disclosed. The method includes determining if at least one new observation model has been created. The method also includes determining if at least one existing observation model is associated with the new observation model. In response to the existing observation model being associated with the new observation model, at least one changed attribute is identified by comparing the new observation model and the existing observation model. A set of files associated with the existing observation model is updated to reflect the changed attribute between the new observation model and the existing observation model.Type: GrantFiled: July 1, 2011Date of Patent: March 11, 2014Assignee: International Business Machines CorporationInventors: Pawan R.
