Base Claim:
1. An apparatus comprising: a processing platform comprising one or more processing devices each comprising a processor coupled to a memory, the processing platform being configured for combined processing of structured and unstructured service event data; the structured service event data comprising service event data stored in one or more structured data fields of a service events database; the unstructured service event data including documents comprising unstructured text data of the service events database, the unstructured service event data comprising unstructured service request summaries including one or more problem summaries and one or more corresponding solution summaries; wherein the processing platform is configured: to apply preprocessing to the unstructured text data by: constructing one or more term indexes of the unstructured text data based at least in part on associations between the unstructured service request summaries and structured data in one or more of the structured data fields of the service events database; generating, for a domain comprising the documents, one or more in-domain dictionaries utilizing the one or more term indexes; processing the one or more in-domain dictionaries to construct a topic model; and automatically determining at least a subset of a plurality of topics automatically utilizing the topic model, as sets of related terms from the unstructured text data, without reference to a set of rules characterizing predefined topics; to assign each of the documents to one or more of a plurality of clusters corresponding to respective topics; to provide an interface configured to permit selection of one or more of the structured data fields; and to generate at least one visualization as a function of the selected one or more structured data fields and particular ones of the cluster topics that relate to the selected one or more structured data fields.

Claim 2:
2. The apparatus of claim 1 wherein selection of the one or more structured data fields via the interface activates a structured data filter which adapts the visualization in accordance with the selected one or more structured data fields.
