Abstract

A system, apparatus, method, and computer program product encoding the method are provided for expectation fulfillment evaluation. The system includes a natural language processing component that extracts sets of normalized tasks from an input expectation document and an input fulfillment document. A task list comparison component compares the two sets of tasks and identifies each match between a normalized task in the first set and a normalized task in the second set, each normalized task in the first set which has no matching task in the second set, and each normalized task in the second set which has no matching task in the first set. A report generator outputs a report based on the comparison. The report may further include one or more of statistics generated from the comparison, information on an opinion generated by opinion mining a third document, and as a list of the normalized tasks and an indication of whether the tasks were fulfilled, derived from analysis of temporal expression in the two documents. The system may be implemented as software in memory by an associated computer processor.
