SETTLEMENT ANALYSIS SYSTEM AND SETTLEMENT ANALYSIS PROGRAM

摘要

PROBLEM TO BE SOLVED: To efficiently and flexibly perform factor extraction from settlement related information.SOLUTION: Factor patterns are stored in a pattern storage part 11. The factor patterns have representation of accounting events including at least items and price information, and representation of factors of the events. A morphological analysis part 5 generates morpheme sequences by performing morphological analysis for each sentence obtained by decomposing sentences included in settlement related information. A labeling part 6 imparts specific attribute labels to morphemes constituting the morpheme sequences or combinations thereof. A pattern comparison unit 7 compares the morpheme sequences abstracted with the attribute labels to the factor patterns stored in the pattern storage part, and determines whether the morpheme sequences match the factor patterns. For the morpheme sequences matching the factor patterns, a factor extraction part 8 extracts portions specified by the factor patterns as factors, and links the extracted factors to the items and price information in the morpheme sequences.SELECTED DRAWING: Figure 1
