First Claim
1. 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, anddynamically 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.

Abstract
Techniques for determining interactive topic-based summarization are provided. A text to be summarized is segmented. Discrete keyword, key-phrase, n-gram, sentence and other sentence constituent based summaries are generated based on statistical measures for each text segment. Interactive topic-based summaries are displayed with human sensible omitted text indicators such as alternate colors, fonts, sounds, tactile elements or other human sensible display characteristics useful in indicating omitted text. Individual and/or combinations of discrete keyword, key-phrase, n-gram, sentence, noun phrase and sentence constituent based summaries are dynamically displayed to provide an overview of topic and subtopic development within a text. A hierarchical and interactive display of texts based on the use of discrete sentence constituent based summaries which associates expansible and contractible displayed text provides contextualized access to an interactive topic-based text summary and to an original text.
