Enhanced Summarizations of Streaming Text
Streams of time-stamped, unstructured text content represent both a valuable information resource for analysts and a daunting volume of input which must be sifted and sorted according to multiple perspectives. Securboration proposes Topical Summarization Over Time (TSOT), which treats summaries as objects which have lifecycles developing as more reports about their real-world events and entities become available. TSOT will allow a human user to explicitly request summaries for a population of documents of interest. More interestingly, TSOT will monitor streaming data sources for topics of interest which form over time, creating summaries as necessary. Such topics arise quickly in message or news traffic, but can very often be aligned to existing Critical Information Requirements (CIR). When a group of documents describes some real world event or situation which matches the criteria of a CIR, TSOT will produce a summary which ties the content directly to the CIR"s specification, orienting the analyst to the important source document statements. Metadata about summary statements will be presented, including a strength of signal, the time signature of the particular information and a measure of reliability of the information. The summary and its metadata will change over time as new developments occur.
