  • Patent number: 11645335
    Abstract: Generating a solution keyword tag cloud is provided. The solution keyword tag cloud is generated for a product based on matching keywords identified in a question asking how to resolve an issue experienced by a user with the product with keyword tags included in a set of condition-solution trees corresponding to the product. In response to receiving an indication that a tried solution in the solution keyword tag cloud did not resolve the issue experienced by the user, the solution keyword tag cloud is graphically updated by moving the tried solution that failed to resolve the issue from a solution section of the solution keyword tag cloud to a condition section of the solution keyword tag cloud. The solution keyword tag cloud is presented in a graphical user interface display on a client device corresponding to the user.

  • Patent number: 11379487
    Abstract: Enhancing a data query is provided. A knowledge base is searched for information corresponding to the data query. It is determined whether a query result is greater than a query result threshold level of information for the data query based on an identified query intent and keywords of the data query. In response to determining that the query result is not greater than the query result threshold level of information for the data query, a set of questions is sent to a personal digital agent of a client device that sent the data query for additional information based on the identified query intent and keywords. Analytic concepts answering the set of questions are received from analytic modules of the personal digital agent that are based on IoT-based personal data corresponding to a user of the client device. The data query is enhanced using the analytic concepts.
