Abstract: An analyzer includes: a reference map receiver configured to receive information regarding a reference map in which reference data are plotted in advance on the basis of similarity index between the reference data; and a new data plotting unit configured to plot new data different from the reference data on the reference map on the basis of the similarity index between the new data and a part or all of the reference data on the reference map.

Abstract: A combined data creating unit, a map creating unit, and a first state analyzer. The combined data creating unit is configured to obtain a device datum. The device datum includes an issued information issued from any device and an issued time of the issued information. The combined data creating unit is configured to create a combined datum by combining the device data related to a state determination target. The map creating unit is configured to map the combined data based on a similarity of the combined data to create a map. The first state analyzer is configured to analyze a determination target state using positions of the combined data disposed in the map.

Abstract: A method of extracting subsets from the whole population of data configured by values of many elements in a case where the subsets have a correlation for a plurality of elements and finding out correlated elements. More specifically, the method comprises modeling data as a vector based on values of all the elements configuring individual data, and, in a multidimensional space in which all the data included in the population is plotted, extracting subsets each having a multidimensional correlation based on the densities of plots, and finding out featured elements having a correlation in the subsets.

Abstract: The data analysis apparatus according to the invention includes an indexing unit configured to calculate indexes indicating similarity between a plurality of segments, each of which is numerical data having at least one frequency component, using a frequency spectrum containing the frequency component of the segment, and a map creating unit configured to plot the segment on a map based on indexes.

Abstract: A document retrieving apparatus can retrieve a target document and output the retrieved target documents according to ranking when a retrieval keyword or retrieval expression is input. However, it requires a skilful technique to narrow a retrieval range since an appropriate retrieval keyword or retrieval expression needs to be created. A document retrieving apparatus of the present invention reads out and compiles a document list included in a designated area when a user designates an area of a document to be read on a two-dimensional map. When the user designates an area of a document to be read on the two-dimensional map, the document retrieving apparatus of the present invention combines query vectors of a plurality of documents included in a designated area and extracts documents based on a combined query vector.
