Abstract:
1. An information processing method, comprising the steps of: obtaining a first format document described using a mark-up language including tags of at least two levels; generating, based on definition data defining a hierarchical relationship of the tags of the mark-up language in a document structure where the tags are lined up according to their respective levels, a second format document representing a tree structure having at least one node thereof corresponding to one of the tags or to a text related to one of the tags from the first format document, wherein a node corresponding to a tag of a higher level is located in parallel and to the left of a node corresponding to a tag of a lower level, wherein the definition data defines a hierarchical relationship of at least heading-related tags out of tags used in the first format document in the document structure; wherein the at least one node includes a node corresponding to a tag marking up a heading; and identifying a set of nodes that satisfy a specified extraction condition from the tree structure represented by the second format document.
