  • Patent number: 11861305
    Abstract: Provided is a word processing system which includes: a first generation unit which generates, based on sentence information including a plurality of sentences, hierarchy data indicating syntax tree data for each hierarchy with regard to each sentence; a second generation unit which acquires, from a plurality of hierarchy data generated by the first generation unit, hierarchy data of a second sentence similar to hierarchy data of a first sentence generated by the first generation unit, extracts a difference between the hierarchy data of the first sentence and the hierarchy data of the second sentence, and generates, as paraphrasing rule data, first expression data as a difference in the first sentence and second expression data as a difference in the second sentence; and a storage unit which stores the paraphrasing rule data generated by the second generation unit in a storage unit.
    Type: Grant

  • Patent number: 9317205
    Abstract: Information processing system for rapidly performing analysis of semistructured data while preserving fault-tolerance of data for a store request acquiring the number which has been stored of the same and data structures set beforehand, refer to data structure management information to determine a data store unit, instructs replica creation of the data with regard to the data stored in the data store unit in which any of the replicas have been stored, transmits an instruction, for performing a data operation, to a data structure operation unit, whereupon a processing unit, in accordance with the content of an analysis request, performs analysis processing by way of either data stored in any of the data storage units after a data structure operation or data which have not been subject to a data structure operation.

  • Publication number: 20160006839
    Abstract: Proposed are a data collection and distribution method, a data collection and distribution apparatus and a program which enable the convenience of a data provider to be improved. A data collection and distribution apparatus, which acquires and stores collected data collected by a data collection client and distributes the collected data to a data destination client, determines whether or not an attribute of the collected data collected from the data collection client is at variance with an attribute according to a prior arrangement, determines a collected data processing method based on a determination result, and selectively distributes the collected data of the attribute according to the prior arrangement to the data destination client based on a determination result.
