Abstract
An electronic document processing apparatus and an electronic document processing method are provided that can perform a sophisticated search such as concept search with a high precision even on images including decorated text strings. Text strings are extracted from an electronic document containing layout information, and a baseline of the extracted text string is detected. Subsequently, a line segment A extending forward from the baseline and a line segment B of a different type from the line segment A extending backward from the baseline are provided. It is determined, for different text strings, that the different text strings are concatenated if the line segments A and B, which are provided for the different text string, overlap with each other.
