-  * The architectural and implementation description of a services index, which, inspired by traditionalWeb ​index, harvests services descriptions from theWeb, builds internal data structures with services representational models, and support automatic services discovery by answering agents queries. The services index exploits the SPARQL expressions defining the services preconditions and effects to build its data structures, and answers SPARQL-based queries. +  * The architectural and implementation description of a //services index//, which, inspired by traditional Web index, harvests services descriptions from the Web, builds internal data structures with services representational models, and support automatic services discovery by answering agents queries.

-  * The architectural and implementation description of a SPARQLent, a goaldirected ​planning agent. The functioning of a SPARQLent is based on the computational model of GpDL; its goal is a SPARQL graph pattern, and its incomplete representation of the world state is an RDF graph. A SPARQLent interacts with a services index during planning, it can reason about services preconditions (graph patters relaxation),​ and compose services sequences through regression planning with cost-based heuristics.  +  * The architectural and implementation description of a //SPARQLent//, a goal directed ​planning agent.

-  * The validation and evaluation of the proposed approach in three different domains. First, a real world use case in the e-Government domain, where we use a services index and a SPARQLent to solve the problem of selecting assistance and welfare services for citizens, thus showing that our approach is general enough to deal also with generic services. Second, an experiment in the domain of collaboration services, where we use a SPARQLent to support the creation of dynamic and personalized collaborative environments. Finally, the evaluation of our approach with respect to the currently available OWL-S Services Retrieval Test Collection, which is intended to support the evaluation of OWL-S services matchmaking algorithms.+  * The //validation and evaluation// of the proposed approach in three different domains.
