Patent number: 9524310Abstract: Data processing includes accessing a product category tree, the product category tree comprising a plurality of hierarchical levels. A leaf category level of the plurality of hierarchical levels comprises a leaf category node. The leaf category node includes product information. The product information comprises a plurality of product attribute parameters. The plurality of product attribute parameters comprises standard product information. Data processing further includes selecting, among the plurality of product attribute parameters that correspond to the leaf category node, a representative product attribute parameter that is representative of the product information; and partitioning standard product information of the leaf category node to obtain a plurality of sets using the representative product attribute parameter, wherein each of the plurality of sets includes at least some of the standard product information.Type: GrantFiled: October 24, 2014Date of Patent: December 20, 2016Assignee: Alibaba Group Holding LimitedInventors: Haijie Gu, Ningjun Su, Qifeng Dai, Haiping Ma, Jinyin Zhang, Enhong Chen

Patent number: 9239395Abstract: Methods for rapidly determining earthquake parameters of an earthquake include inputting a seismogram of the earthquake, searching concurrently in pre-established historical seismogram database and theoretical seismogram database by use of an approximate nearest neighbor search method, to find a set of seismograms similar to the input seismogram according to a preset similarity condition, and determining from the set of similar seismograms one or more seismograms matched with the input seismogram, and determining the earthquake parameters from the matched seismograms. With the present invention, it is possible to search in millions of seismograms and determine parameters for an earthquake in a few second, and thus realize rapid and even real-time estimation of earthquake parameters.Type: GrantFiled: May 24, 2012Date of Patent: January 19, 2016Assignee: University of Science and Technology of ChinaInventors: Jie Zhang, Haijiang Zhang, Enhong Chen, Yi Zheng, Wenhuan Kuang

Publication number: 20140074639Abstract: An approach is provided for a holistic framework to model user item rating with user generated tag information. A tagging manager determines one or more tags associated with one or more items, wherein the one or more tags are generated by one or more users. The tagging manager processes and/or facilitates a processing of the one or more tags to cause, at least in part, a generation of one or more semantic spaces. The one or more semantic spaces and/or one or more semantic concepts within the one or more semantic spaces represent one or more groupings of the one or more tags. The tagging manager determines one or more probability parameters that the one or more tags, the one or more users, the one or more items, or a combination thereof are associated with respective ones of the one or more semantic concepts in the semantic spaces.Type: ApplicationFiled: May 16, 2011Publication date: March 13, 2014Applicant: Nokia CorporationInventors: Jilei Tian, Tengfei Bao, Happia Cao, Enhong Chen
