Time series pattern extraction apparatus and method
First Claim
1. An apparatus for extracting a time series pattern, comprising:
- an input unit inputting a plurality of time series data, each time series data being an electronic daily report including a plurality of data elements, each data element including a time and a text;
a data memory storing the plurality of time series data;
an extraction rule memory storing a correspondence relation between a key concept and a text expression;
a time series pattern generation unit configured to extract key concepts corresponding to the text of each data element of the plurality of time series data from said extraction rule memory, and to generate a plurality of time series patterns from the plurality of time series data, each pattern including data elements each having a time and a key concept;
a colony generation unit configured to unify a plurality of data elements having the same key concept and substantially the same time duration, and to generate colonies of unified data elements;
a select unit selecting a first colony from the colonies in response to a user'"'"'s operation, the first colony having a first key concept;
a colony extraction unit configured to specify a second colony having a second key concept contrary to the first key concept, and to extract colonies each having a time earlier than the first colony and the second colony;
a time reason extraction unit configured to extract a time reason as a divergence condition of the first colony from the second colony from the extracted colonies; and
a display unit displaying the first colony, the second colony, the extracted colonies, and the time reason.

Abstract
A time series pattern generation unit extracts a key concept corresponding to a text of each data element of a plurality of time series data by referring to an extraction rule memory, and generates a plurality of time series patterns. A colony generation unit unifies a plurality of data elements having the same key concept and substantially the same time duration, and generates colonies of unified elements. In response to a selection of a first colony, a colony extraction unit specifies a second colony having a key concept contrary to the first colony, and extracts colonies earlier than the first colony and the second colony. A time reason extraction unit extracts a time reason as a divergence condition of the first colony from the second colony from the extracted colonies.
