Abstract
A digital-content-analysis system includes a network services component adapted to receive a remote service request, a stream monitor adapted to form digital content into at least one data stream, and a stream analyzer interoperably coupled to the network services component and the stream monitor and adapted to receive and analyze the at least one data stream. The stream analyzer includes a lexical analyzer adapted to separate the at least one data stream into a plurality of tokens, a classifier adapted to classify the at least one data stream into at least one category by processing at least a subset of the plurality of tokens and computing a classification rating for at least one category, and a set of parameters. At least a subset of the parameters contains information developed from previous operation of the stream analyzer.
