Abstract: The present invention may include an embodiment to improve the performance (both response time and quality of answers) of a knowledge based service operating on a master catalog of data by dynamically building a narrowed, focused, and reduced corpus of data over which the knowledge based service operates. The embodiment may identify a corpus catalog for a knowledge base service, where the knowledge base service includes one or more documents. Then the embodiment may determine one or more subjects based on profile preferences of a user and determining the one or more documents corresponding to the determined one or more subjects based on determining the one or more subjects were updated. The embodiment may stage the determined one or more documents in a master corpus, where the master corpus is a subset of the corpus catalog and upload the master corpus to the knowledge base service.

Abstract: A system includes a deep question answering system executed by a computer, a processor, and a memory coupled to the processor. The memory is encoded with instructions that when executed cause the processor to provide a document ingestion system for ingesting user specific documents into the deep question answering system. The document ingestion system is configured to initialize a user specific document collection, the user specific document collection being specific to a user, obtain an indication that the user is interested in a first document based on an interaction between the user and a shallow analytic system, include the first document in the user specific document collection, and ingest the user specific document collection into the deep question answering system.
