Abstract: Computer-readable media, systems, and methods for document layout extraction are described. In embodiments, textual data in an electronic format is received and the textual data is converted from the electronic format to an independent interface format, the independent interface format including coordinates to one or more structural elements of the textual data. Further, in embodiments, a structure and layout analysis of the textual data is performed to generate a set of structure and layout information. Still further, in embodiments, the textual data and the set of structure and layout information is stored in an enriched interface format, the enriched interface format providing for search and navigation of the textual data.

Abstract: Computer-storage media, computerized methods and systems for classifying character strings within electronic documents are provided. Initially, textual data, which includes one or more character strings, is extracted from an electronic version of a document, typically scanned from a physical document utilizing optical character recognition. The textual data is received at a table-of-contents (TOC) engine that extracts semantic information from the textual data. Sub-engines within the TOC engine analyze the semantic information to determine at least one appropriate classification for character strings within the textual data. Labels selected from a predetermined set of TOC-architecture labels are appended to the character strings according to the appropriate classification. The character strings, and labels appended thereto, are stored in association with each other generating an electronic document file that includes enriched textual data.
