  • Clustering facets on a two-dimensional facet cube for text mining
    Patent number: 10657145
    Abstract: A computer-implemented method and system for clustering facets on a two-dimensional facet cube for text mining. The method and system performs text mining based on facets to analyze unstructured data in one or more documents by generating a two-dimensional facet cube that is a correlation matrix for one or more facets associated with a set of one or more of the documents; grouping one or more of the facets in the correlation matrix into at least one cluster; calculating a center for the cluster; and identifying facets that are located near the calculated center of the cluster as being representative of the cluster.

  • Large scale facet counting on sliced counting lists
    Patent number: 10585928
    Abstract: An approach is provided in which an information handling system matches a set of documents, from a corpus of documents, to a query received from a client. The information handling system determines an amount of facets corresponding to the matching set of documents by dynamically dividing the corpus of documents into multiple sub-corpuses and performing complement facet counting on at least one of the sub-corpuses. In turn, the information handling system sends a set of results to the client that includes the determined amount of facets corresponding to the matching set of documents.
