  • Publication number: 20100017256
    Abstract: A method of managing a hierarchically structured project on a computer. The method defines each of subprojects composing the hierarchical structure, define each structure of the works composing each subproject, stores information about each work of the subproject, collects information about the corresponding works among the subprojects selected by the user as a compound work, and displays the information about the work on the compound-work basis.

  • Publication number: 20060236241
    Abstract: The objective of this application is to make it possible to timely acquire the user's evaluation about evaluation-targeted content. A survey window is provided to include a title region, an operation region and a content region. The content region indicates the evaluation-targeted content that the evaluator evaluates. The operation region indicates photographs of agent's faces as help buttons, and feeling input buttons that the evaluator selectively operates according to the emotion experienced when estimating the evaluation-targeted content. The evaluator selectively operates the feeling input buttons when the evaluator experiences an emotion while browsing the evaluation-targeted content to estimate. Thus, the evaluation about the evaluation-targeted content can be more accurately obtained.

  • Publication number: 20040205657
    Abstract: The present invention provides a data linking method, for use in design development work, that solves the problem of the need to re-enter data or of a delay in reflecting data that may occur when a progress management unit, a review management unit, and a pending issue management unit for work items perform operation independently. The method according to the present invention creates a review report template including review items defined by a review report management system and pending issues registered with a pending issue management system, extracts pending issues and approved information from a review report created based on the review report template, registers the extracted pending issues and information with the pending issue management system, calculates a solution status and a discussion status of the document from the review report, and registers the calculated status with an work item management system.

  • Patent number: 5802509
    Abstract: A rule generation apparatus includes a label presenter in which when producing from training data including a set of specific values related to input and output variables rules representing input/output relationships between the input and output variables, numeric data of the training data is converted into categorical data expressed by symbols to generate an instance table, an RI device for extracting rules from the instance table, and a rule converter for converting the extracted rules into fuzzy rules. When the training data is divided to be distributively stored in a plurality of server processors, label assignment is conducted by each server processor such that a client processor later combines instance tables with each other to achieve rule induction and conversion.
