Abstract: An apparatus comprises a processing platform configured to implement an analysis and visualization tool for combined processing of structured and unstructured service event data. The structured service event data comprises service event data stored in one or more structured data fields of a service events database, and the unstructured service event data includes documents comprising unstructured text data of the service events database. The analysis and visualization tool is associated with a clustering module that assigns each of the documents to one or more clusters corresponding to respective topics. The analysis and visualization tool comprises an interface that permits selection of one or more of the structured data fields, and a visualization module configured 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.

Abstract: An apparatus comprises a processing platform configured to implement a cluster labeling system for documents comprising unstructured text data. The cluster labeling system comprises a clustering module and a visualization module. The clustering module implements a topic model generator and is configured to assign each of the documents to one or more of a plurality of clusters based at least in part on one or more topics identified from the unstructured text data using at least one topic model provided by the topic model generator. The visualization module comprises multiple view generators configured to generate respective distinct visualizations of a selected one of the clusters. The multiple view generators include at least a bigram view generator configured to provide a visualization of a plurality of term pairs from the selected cluster, and a summarization view generator configured to provide a visualization of representative term sequences from the selected cluster.

Abstract: 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.
