System and Method for Automatic, Unsupervised Contextualized Content Summarization of Single and Multiple Documents

A system comprising:

• a hardware processor;
• a data bus coupled to the processor;
• and
• a computer-usable medium embodying computer program code, the computer-usable medium being coupled to the data bus, the computer program code used for generating a context-sensitive summarization of a corpus of content, the context-sensitive summarization being performed by an automated summarization system executing on the hardware processor of the system, and comprising instructions executable by the processor and configured for:
• receiving an input corpus to the automated summarization system via a network;
• processing the input corpus to extract phrases via the automated summarization system;
• using the phrases to generate a grammatical analysis of the input corpus via the automated summarization system;
• using the grammatical analysis to determine the thematic relevance of sentences in the input corpus via the automated summarization system;
• ranking the sentences according to their thematic relevance to form a context-based ranking via the automated summarization system;
• using the context-based ranking to construct a context graph for the phrases via the automated summarization system;
• using the context graph to generate a content summarization of the input corpus via the automated summarization system, the content summarization comprising ranked sentences;
• using a stochastic matrix combined with a damping factor to determine an order of the ranked sentences in the content summarization;
• and,
• generating an output summary to the network via the automated summarization system, the output summary simplifying information search and limiting a need to access original source content.
