TABLE RECOGNITION METHOD AND TABLE RECOGNITION DEVICE

摘要

PROBLEM TO BE SOLVED: To determine whether a character string in a table is an item or data while solving ambiguity thereof. SOLUTION: The ambiguity of an item or data is solved by the following steps. (1) An item likelihood of each character string is calculated based on a language pattern and a layout pattern. (2) A word co-occurrence likelihood and a layout pattern co-occurrence likelihood are calculated for each combination of labels of vertically and laterally adjacent character strings. (3) A combination of labels is selected wherein the product of the likelihood by (1) and the likelihoods by (2) is the highest. COPYRIGHT: (C)2009,JPO&INPIT
