Ontologies can be widely taken advantage of in recommender systems, since they provide a means of classifying and discovering of new information about the items to recommend, about user profiles and even about their context.

Wikis are a great tool inside the Social Web, as they provide the chance of creating collaborative knowledge in a quick way. Semantic wikis are becoming popular as Web technologies evolve: ontologies and semantic markup on the Web allow the generation of machine-readable information.

Shape grammars are a powerful and appealing formalism for automatic shape generation in computer-based design systems. This paper presents a proposal complementing the generative power of shape grammars with reinforcement learning techniques. We use simple (naive) shape grammars capable of generating a large variety of different designs. In order to… (More)
This paper shows some fuzzy generalizations of the concepts of derivation and computation with shape grammars. Fuzzy definitions are provided for both rule application and shape matching. The paper also describes a software prototype developed to test these ideas.
A proposal is presented to enhance the usability of shape grammars by using explicit constraints and policies on rule selection.
