A computer program product and method provides a question and answer service that accepts an initial first question from a user and analyzes the question by a first generation subsystem to generate a first answer. A second generation subsystem of the question and answer service is configured to generate a second question based at least in-part on keywords from the first question and the first answer.
Please help me write a proper abstract based on the patent claims. CLAIM: 1. A question-answering system comprising: a processor configured to: receive a first question input into a user interface by a user; analyze the first question by a computer device utilizing a corpus of data to determine a computer generated first answer to the first question; extract a set one or more keywords from the first answer and the first question; remove at least one keyword from the set of one or more keywords to create a subset of one or more keywords, wherein removing the at least one keyword is based at least in-part on a comparison of the at least one keyword to the first question; and output a computer generated second question based at least in-part on the first question, wherein the second question is based in-part on the subset of one or more keywords from the first answer and the first question. 2. The question-answering system set forth in claim 1, wherein the processor is further configured to receive a selection of the second question from the user. 3. The question-answering system set forth in claim 2, wherein the processor is further configured to: analyze the second question by the computer device; and output a computer generated second answer to the second question. 4. The question-answering system set forth in claim 3, wherein the second question is one of a plurality of second question available for selection by the user. 5. The question-answering system set forth in claim 3, wherein the first answer is generated by a first generation subsystem of the question and answer system. 6. The question-answering system set forth in claim 5, wherein the second question is generated by a second generation subsystem of the question-answering system. 7. The question-answering system set forth in claim 6, wherein the second answer is generated by the first generation subsystem. 8. The question-answering system set forth in claim 1, wherein the second question is semantically similar to the first question. 9. The question-answering system set forth in claim 1, wherein the processor is further configured to utilize a taxonomy template by the computer device for, at least in-part, generating the second question. 10. The question-answering system set forth in claim 9, wherein the taxonomy template is based on a subject of the corpus of data. 11. A question-answering system comprising: a processor configured to: receive a first question input into a user interface by a user; analyze the first question by a computer device utilizing a corpus of data; output a computer generated first answer to the first question; output a computer generated second question based at least in-part on the first question, wherein the second question is based in-part on the first answer; and select keywords of the first answer by the computer device to at least in-part generate the second question. 12. The question-answering system set forth in claim 11, wherein the processor is further configured to select of the second question by the user. 13. The question-answering system set forth in claim 12, wherein the processor is further configured to: analyzing the second question by the computer device; and outputting a computer generated second answer to the second question. 14. The question-answering system set forth in claim 13, wherein the second question is one of a plurality of second question available for selection by the user. 15. The question-answering system set forth in claim 13, wherein the first answer is generated by a first generation subsystem of the question and answer system. 16. The question-answering system set forth in claim 15, wherein the second question is generated by a second generation subsystem of the question-answering system. 17. The question-answering system set forth in claim 16, wherein the second answer is generated by the first generation subsystem. 18. The question-answering system set forth in claim 11, wherein the second question is semantically similar to the first question. 19. The question-answering system set forth in claim 11, wherein the processor is further configured to utilize a pre-created taxonomy template by the computer device for, at least in-part, generating the second question. 20. The question-answering system set forth in claim 19, wherein the pre-created taxonomy template is based on a subject of the corpus of data.
