  • Publication number: 20180101578
    Abstract: An evaluation apparatus acquires estimated values of values indicating certain feature of a plurality of entities, respectively. Next, the evaluation apparatus determines, among the plurality of entities, entities, each of which is associated with the same value as a corresponding estimated value by specified relation information, to be first entities and holds the specified relation information. Next, the evaluation apparatus determines, among the plurality of entities, entities, each of which is associated with a value different from a corresponding estimated value by the specified relation information, to be second entities. Next, the evaluation apparatus calculates a concordance rate between the estimated values for the respective entities and the values associated with the respective entities by the specified relation information, based on the number of first entities and the number of second entities.

  • Publication number: 20150186476
    Abstract: An acceptance unit accepts a focus and a standpoint from a user, and a page screen generation unit acquires a page screen definition on the basis of the standpoint. A gadget screen generation unit then uses a plurality of gadget definitions included in the page screen definition to generate a plurality of pieces of gadget screen data. A screen display unit thereafter displays a screen including the plurality of gadget screens. When a company corresponds to the focus and a vendor organization corresponds to the standpoint, for example, a search unit displays on the gadget screen a pie chart representing a sum of order volume by each orderer, a pie chart representing a sum of order volume by each orderer including affiliated companies, and an organization chart.

  • Patent number: 8898168
    Abstract: An information searching apparatus retrieves a sub graph matching an inquiry graph from a graph to be searched. The apparatus includes an extracting unit that extracts, from among clusters of nodes in the graph to be searched, plural cluster pairs that each include a first cluster and a second cluster including a node linked by a link to a node in the first cluster and a calculating unit that calculates a bonding strength for each of the cluster pairs. The apparatus further includes a determining unit that determines, among the cluster pairs and based on the bonding strength of each of the cluster pairs, a cluster pair to be merged; a merging unit that merges the cluster pair; and a searching unit that searches the merged clusters for a sub graph matching the inquiry graph. An output unit outputs a search result of the searching unit.

  • Patent number: 7630979
    Abstract: An information retrieval terminal provides keywords to an information retrieval device and instructs it to retrieve by using such keywords. The information retrieval terminal includes an information collector for collecting screen information, image information, and voice information around the information retrieval terminal and for obtaining text information from the collected information. A keyword-candidate extracting unit extracts a word related to a retrieval word input by a retriever from the text information obtained by the information collector, and sets the extracted word to be a keyword candidate. A retrieval instructing unit gives an instruction to retrieve by using the retrieval word and the keyword candidate set by the keyword-candidate extracting unit as keywords.
