In this paper we give algorithms for the construction of a 2D interactive parser which helps a user to construct correct two-dimensional iconic sentences according to positional LALR grammars. At each step of the parsing process the user is provided with a feasible set of icons. Moreover, the areas on the screen where each icon in the set may be placed are highlighted. In this way both syntactic and structural errors are avoided.

Abstract
In this paper we give algorithms for the construction of a 2D interactive parser which helps a user to construct correct two-dimensional iconic sentences according to positional LALR grammars. At each step of the parsing process the user is provided with a feasible set of icons. Moreover, the areas on the screen where each icon in the set may be placed are highlighted. In this way both syntactic and structural errors are avoided.File in questo prodotto:
