Efficient parsing of multidimensional structures

Abstract
Visual languages have motivated growing interests in the investigation of grammatical formalisms and parsing algorithms for modelling and recognizing multidimensional structures. The effectiveness of visual languages require that some efforts must be accomplished to obtain efficient parsing techniques. A general parsing scheme for relation grammars is presented. The class RG/1 of grammars is characterized which seems to be well suited for modelling visual languages of practical use. An efficient O(n log n) parsing algorithm is also given.<>
