Patent number: 11423229Abstract: Implementations of the subject matter described herein relate to conversational data analysis. After a data analysis request is received from a user, heuristic information may be determined based on the data analysis request. The heuristic information mentioned here is not a result for the data analysis request but information which may be used for leading the conversation to proceed. Based on such heuristic information, the user may provide supplementary information associated with the data analysis request, for example, clarify meaning of the data analysis request, submit a relevant further analysis request, and so on. A really desired and meaningful data analysis result can be provided to the user according to the supplementary information provided by the user. Thus, data analysis will become more accurate and effective. While obtaining really helpful information, the user also gains good user experience.Type: GrantFiled: September 22, 2017Date of Patent: August 23, 2022Assignee: Microsoft Technology Licensing, LLCInventors: Zhitao Hou, Jian-Guang Lou, Bo Zhang, Xiao Liang, Dongmei Zhang, Haidong Zhang

Patent number: 11372869Abstract: A system for frequent pattern mining uses two layers of processing: a plurality of computing nodes, and a plurality of processors within each computing node. Within each computing node, the data set against which the frequent pattern mining is to be performed is stored in shared memory, accessible concurrently by each of the processors. The search space is partitioned among the computing nodes, and sub-partitioned among the processors of each computing node. If a processor completes its sub-partition, it requests another sub-partition. The partitioning and sub-partitioning may be performed dynamically, and adjusted in real time.Type: GrantFiled: June 1, 2018Date of Patent: June 28, 2022Assignee: Microsoft Technology Licensing, LLCInventors: Shi Han, Yingnong Dang, Dongmei Zhang, Song Ge

Publication number: 20210117625Abstract: According to implementations of the subject matter described herein, there is proposed a solution for semantic parsing of a natural language query. In this solution, a plurality of words in a natural language query for a data set are replaced with a plurality of predetermined symbols to obtain an abstracted utterance. The abstracted utterance is parsed into a plurality of logical representations by applying different deduction rule sets to the abstracted utterance, each logical representation corresponding to a predictive semantic of the natural language query. A logical representation is selected based on the predictive semantics corresponding to the plurality of logical representations for generating a computer-executable query for the data set. Through this solution, a natural language query is converted to a computer-executable query quickly in a data-agnostic and syntax-agnostic manner.Type: ApplicationFiled: June 17, 2019Publication date: April 22, 2021Inventors: Yan Gao, Bo ZHANG, Jian-Guang LOU, Dongmei ZHANG
