This paper presents a simplified approach to processing of ambiguous requests in spoken dialogues in information train timetable service systems. The simplified processing of ambiguous and incomplete utterances is based on a simple representation of the semantics of analyzed utterances by specially constructed frames, on the special representation and storage of facts extracted from the previous steps of dialogue (dialogue path, or dialogue history), and on the creation of the simple knowledge base containing the reasoning rules linking the meaning detected in the analyzed user's utterance with the facts stored in the dialogue path or in the system knowledge base. Some aspects of the implementation of utterance internal representing frames completion and their evaluation are discussed in the concluding part of this paper.
