A computer analyzes blockchain ledger content. The computer receives a set of attributes associated with a predetermined entity and applies a one-way function to the attributes, generating an inquiry hash. The computer receives access to a blockchain ledger that includes a report with at least one report hash associated with an attribute of a report entity. The computer searches the report using the inquiry hash as a search key. The computer generates a list of candidate reports containing hashes that matches the inquiry hash. The computer assigns an entity matching confidence rating to candidate reports based, at least in part, on a predetermined identification utility value associated with each inquiry hash matched. The identification utility value indicates a likelihood that the report entity is the predetermined entity. The computer generates a list of high assurance reports having entity matching confidence ratings above a predetermined assurance threshold.

Embodiments are provided that relate to a computer system, a computer program product, and a machine-implemented method for improving performance of a dialog system employing an automated virtual agent. Embodiments involve clustering traces of dialog conversation logs into sets, and searching the traces for one or more contrastive temporal patterns between the sets.

A system and method for carrying out transitions from legacy to new applications includes the definition of relational database views to permit relational queries defined for a database having a legacy schema to be run against a database having a new schema. The relational database views for the database having a new schema are generated with reference to and by selection from a set of database views defined for possible schema changes. The post-transition display of legacy display pages is handled by the preferred embodiment through the use of a view registry that associates a defined display view with a legacy view engine and a legacy display page.
