In this paper we present a new approach to deal with attributed graphs and attributed graph transformation. This approach is based on working with what we call symbolic graphs, which are graphs labelled with variables together with a formula that constrains the possible values that we may assign to these variables. In particular, in this paper we will compare in detail this new approach with th...

We describe an approach for retrieving threedimensional objects similar to a given one from a database. The key idea of our technique is to decompose each object into its meaningful components, and fit each component to a basic shape. This decomposition is represented as an attributed graph, which is considered the signature of the object. Our signature leverages human vision theories such as M...

Attribute grammars can be considered as an extension of context-free grammars, where the attributes are associated with grammar symbols, and the semantic rules deene the values of the attributes. This formalism is widely applied for the speciication and implementation of the compilation-oriented languages. The paper presents a method for learning semantic functions of attribute grammars which i...
