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 computer implemented method of operating a question-answering system comprising: receiving a first question input into a user interface by a user; analyzing the first question by a computer device utilizing a corpus of data to determine a computer generated first answer to the first question and; outputting a computer generated second question based at least in-part on the first question, wherein the second question is based in-part on keywords from the first answer and the first question. 2. (canceled) 3. (canceled) 4. The method set forth in claim 1 further comprising: receiving a selection of the second question from the user. 5. The method set forth in claim 4 further comprising: analyzing the second question by the computer device; and outputting a computer generated second answer to the second question. 6. The method set forth in claim 5, wherein the second question is one of a plurality of second question available for selection by the user. 7. The method set forth in claim 5, wherein the first answer is generated by a first generation subsystem of the question and answer system. 8. The method set forth in claim 7, wherein the second question is generated by a second generation subsystem of the question-answering system. 9. The method set forth in claim 8, wherein the second answer is generated by the first generation subsystem. 10. The method set forth in claim 1, wherein the second question is semantically similar to the first question. 11. The method set forth in claim 1, further comprising: utilizing a pre-created taxonomy template by the computer device for, at least in-part, generating the second question. 12. The method set forth in claim 11, wherein the pre-created taxonomy template is based on a subject of the corpus of data.
