US Patent 9378200 Automated content inference system for unstructured text data

An apparatus comprises a processing platform configured to implement an automated content inference system for unstructured text data. The automated content inference system comprises a data indexer, a dictionary generator, a topic model generator, and a visualization generator. The data indexer is configured to process the unstructured text data to construct a term index for a given document. The dictionary generator is configured to process the term index to construct an in-domain dictionary. The topic model generator is configured to process the in-domain dictionary to construct a topic model. The visualization generator is configured to provide an output display showing assignment of one or more topics to the given document based on the topic model. The unstructured text data illustratively comprises unstructured service request summaries from a service events database. The unstructured service request summaries may comprise problem summaries and corresponding solution summaries relating to respective service events.
