In natural language processing, many methods have been proposed to solve the ambiguity problems. In this paper, we propose a technique to combine a method of interactive disambiguation and automatic one for alnbiguous words. The characteristic of our method is that the accuracy of the interactive disambiguation is considered. | Combination of an Automatic and an Interactive Disambiguation Method Masaya Yamaguchi Takeyuki Kojima Nobuo Inui Yoshiyuki Kotani and Hirohiko Nisimura Department of Computer Science Tokyo University of Agriculture and Technology Nisimura Kotani unit 2-24-16 Naka-cho Koganei Tokyo Japan Abstract In natural language processing many methods have been proposed to solve the ambiguity problems. In this paper we propose a technique to combine a method of interactive disambiguation and automatic one for ambiguous words. The characteristic of our method is that the accuracy of the interactive disambiguation is considered. The method solves the two following problems when combining those disambiguation methods 1 when should the interactive disambiguation be executed 2 which ambiguous word should be disambiguated when more than one ambiguous words exist in a sentence Our method defines the condition of executing the interaction with users and the order of disambiguation based on the strategy where the accuracy of the result is maximized considering the accuracy of the interactive disambiguation and automatic one. Using this method user interaction can be controlled while holding the accuracy of results. 1 Introduction In natural language processing many methods have been proposed to solve the ambiguity prob-lems Nagao and Maruyama 1992 . One of those technique uses interactions with users because it is difficult to make all the knowledge for disambiguation beforehand. That technique is classified into two types according to the condition of executing user interaction. One TypeA is that the disambiguation system executes interactionsf Blanchon et al. 1995 Maruyama and Watanabe 1990 Yamaguchi et al. 1995 . Another type TypeB is that users executes interactions and Niren-burg 1990 Muraki et al. 1994 . In this paper Ty-peA will be adopted because TypeB gives users more trouble than TypeA does. For example in TypeB a user may have to find where is wrongly analyzed .
