This paper describes a way to use Natural Language Processing (NLP) techniques in order to gain faster access to information from a closed domain. Using traditional graphical user interfaces built as a tree structure, such as menus, determine users to browse irrelevant information. To avoid this, we use one of the major tasks in NLI, Question Answering (QA) and build with Visual FoxPro 9.0 a demonstrating application. We impose restrictions related to the domain of use that of tourist attractions in Romania, and restrictions related to natural language input method. We use tags to represent words or groups of words and patterns to symbolize questions. We use this representation in order to provide to user a non-traditional human-computer interaction. The QA system rely on a database where we store specific information on chosen domain and related data in order to accomplish the task of providing an answer. The answering mechanism uses a knowledge engineering with syntactic and semantic approach. At the end of this paper we discuss the QA System Evaluation.
