Political Question Generation Method Using Minutes of Municipal Councils

摘要

This paper proposes a generation method of political questions which include Japanese noun phrases of the form N_1 no N_2. We focus on generating a yes-no question whether a user is interested in an utterance of a councilor. An example of political questions shows as follows: nisankatanso(N_1) no haisyutu(N_2) nituite kuwasiku siritai desu ka? (Do you want to know emissions of carbon dioxide?). In this paper, "N_1" and "N_2" mean a noun or a compound noun. The form N_1 no N_2 which include the Japanese postpositional "no" has a much broader usage. These expressions of the form N_1 no N_2 cannot often use a question expression for asking the interesting such as "simin no minasan(All of citizen)". Therefore, our method checks on an expression whether a user can understand the meaning of that as a question expression. Moreover, our method expands the expression of N_1 when a question expression of N_1 no N_2 is ambiguous. We obtained good results in the experimental result.
