TABLE STRUCTURE ANALYZING APPARATUS, TABLE STRUCTURE ANALYZING METHOD, AND TABLE STRUCTURE ANALYZING PROGRAM

摘要

A table structure analyzing apparatus extracts first row data and second row data in table data. Similarity between the data is computed based on Levenshtein distance or the number of characters. Further, similarity between the first row and the second row as a whole is determined. When the similarity is equal or less than a predetermined threshold value, it is determined that the boundary between the first and second rows is the boundary between a header part and a substantive part. A similar determination is made in the direction of columns.
