A Translation Method from Natural Language Specifications of Communication Protocols into Algebraic Specifications Using Contextual Dependencies

This paper presents a method of translating natural language specifications of communication protocols into algebraic specifications. Such a natural language specification specifies action sequences performed by the protocol machine (program). Usually, a sentence implicitly specifies the state of the protocol machine at which the described actions must be performed. The authors propose a method of analyzing the implicitly specified states of the protocol machine taking the OSI session protocol specification (265 sentences) as an example. The method uses the following properties: (a) syntactic properties of a natural language (English in this paper); (b) syntactic properties introduced by the target algebraic specifications, e.g., type constraints; (c) properties specific to the target domain, e.g., properties of data types. This paper also shows the result of applying this method to the main part of the OSI session protocol specification (29 paragraphs, 98 sentences). For 95 sentences, the translation system uniquely determines the states specified implicitly by these sentences, using only (a) and (b) described above. By using (c) in addition, each implicitly specified state in the remaining three sentences is uniquely determined.
