Deep Semantics of Visual Languages
Pavel Grigorenko, Enn Tyugu · Joint Conference on Knowledge-Based Software Engineering · 2006
Visual specification of software is gaining popularity, but its usage is restricted by the lack of precise semantics of visual languages. In the present work, precise semantics of visual languages is defined. Three kinds of deep semantics of schemes are presented as different ways of usage of attribute models of schemes. Attribute models of a wide class of schemes are defined and higher-order attribute models are introduced. Dynamic evaluation of attributes is used in defining semantics of schemes.
