This paper is concerned with how to retrieve Collision Regulations. In this paper, the authors propose necessity of free-key-word-retrieval and syntactic-retrieval considering syntactic structure of Collision Regulations. Collision Regulations were processed to the form of syntactic structure and syntactic-retreival was executed. For the purpose of free-key-word-retreival, Collision Regulations were processed to the form of list structure of Prolog. And free-key-word-retrieval was executed by character by character unification. The results of this research may be summarized as follows. 1) Syntactic-retrieval is useful method in retrieving Collision Regulations. 2) The combination of free-key-word-retrieval and syntactic-retreival can perform effective retreival of Collision Regulations. 3) BNF (Backus-Naur form) can be applied for parsing Collision Regulations to the form of syntactic structure.
