Patent ID: 7451395

Claim:
A method of determining interactive topic-based text summaries comprising the steps of: dynamically determining a text to summarize; dynamically determining at least one text segment of the determined text to summarize; dynamically determining at least one sentence constituent based summary type; and dynamically determining at least one discrete interactive topic-based text summary for a determined segment based on the determined sentence constituent based summary type and a statistical measure of text segment characterization and text segment differentiation; dynamically determining a subtopic development by recursively repeating the step of dynamically determining at least one sentence constituent based summary type and the step of dynamically determining at least one discrete interactive topic-based text summary, the subtopic development arranged as a hierarchy including at least one subtopic of the at least one discrete interactive topic-based text summary; dynamically determining at least one text segment related to a subtopic of the topic-based text summary to summarize based on dynamic user selections; storing in an electronic memory storage at least one discrete interactive topic-based text summary based on the at least one text segment of the determined text and the at least one determined sentence constituent based summary type; storing the subtopic development in the electronic memory storage, and dynamically displaying at least one discrete interactive subtopic-based text summary based on the at least one text segment related to a subtopic of the topic-based text summary and wherein a human sensible display characteristic indicates omitted text for the subtopic-based text summary.
