Abstract : Consider a study of the processing of questions input to a computerized question-answering system such as the RAND Relational Data File (see AD-642 120). The process consists of (1) transforming the natural-language question into a symbolic question (i.e., a certain formula of predicate calculus) and (2) generating the answer by calculating the value set of the resulting formula. This study is addressed to the second step. A key problem is the identification of 'reasonable' input queries.
