Abstract : Consider a study of the processing of questions input to a computerized questionanswering system such as the RAND Relational Data File (see AD642 120). The process consists of (1) transforming the naturallanguage 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.
