Abstract
A computer system is provided for automatically answering natural language questions. The system has an input to receive natural language questions and a data store to record linked pairs of questions and corresponding answers. A matcher is configured to compare a received natural language question with the linked question and answer pairs, and an output transfers the received natural language question to a researcher if no matches are found. The system links pairs of questions and corresponding answers into groups, to enable the generation of a prototypical answer for each group of pairs of questions and answers.
