Document heading detection

A system to detect document headings, the system comprising:

• a memory storing executable instructions;
• and a processor, wherein when executing the executable instructions, the processor is caused to:
• receive a plurality of paragraphs in a document created with an authoring application, wherein each of the plurality of paragraphs includes content;
• perform a binary classification analysis on the content of each of the plurality of paragraphs to identify each paragraph as either a heading paragraph or a non-heading paragraph, the binary classification analysis assessing the content of each of the plurality of paragraphs through use of a boosted decision tree containing a plurality of content features having been pre-determined from historical content as indicative of a heading paragraph;
• perform a heading level classification for at least two paragraphs identified as heading paragraphs as being at one of a plurality of heading levels in a heading hierarchy, wherein performance of the heading level classification includes:
• determination of a strength value for the at least two paragraphs identified as heading paragraphs based on a subset of the plurality of content features;
• and
• assignment of the at least two heading paragraphs to one of the heading levels based on the determined strength value.

A computer storage media that stores computer-executable instructions, the instructions direct a computer to:

• receive a plurality of paragraphs in a document created with an authoring application, wherein each of the plurality of paragraphs includes content;
• perform a binary classification analysis on the content of each of the plurality of paragraphs to identify each paragraph as either a heading paragraph or a non-heading paragraph, the binary classification analysis assessing the content of each of the Plurality of paragraphs through use of a boosted decision tree containing a plurality of content features having been pre-determined from historical content as indicative of a heading paragraph;
• perform a heading level classification for at least two paragraphs identified as heading paragraphs as being at one of a plurality of heading levels in a heading hierarchy, wherein performance of the heading level classification includes:
• determination of a strength value for the at least two Paragraphs identified as heading paragraphs based on a subset of the plurality of content features;
• and
• assign the at least two heading paragraphs to one of the heading levels based on the determined strength.
