• 論文の詳細を見る

• A new programming language named PLATON (Programming Language for Tree OperatioN),which has the facilities of pattern matching and flexible backtracking, is described. The language is developed in order to make it easy to write an analysis program of natural language. The pattern matching process not only checks whether a rewriting rule is applicable or not, but also extracts sub-strings from the input sentence and invokes appropriate semantic and contextual checking functions. We can set up arbitrary numbers of decision points in a program. If a failure occurs, the control will be changed appropriately according to the cause of the failure. By means of using this mechanism, we can write fairly complicated non-deterministic programs in a simple manner.
