dbrec — Music Recommendations Using DBpedia
Abstract. This paper describes the theoretical background and the im-plementation of dbrec, a music recommendation system built on top of DBpedia, offering recommendations for more than 39,000 bands and solo artists. We discuss the various challenges and lessons learnt while build-ing it, providing relevant insights for people developing applications con-suming Linked Data. Furthermore, we provide a user-centric evaluation of the system, notably by comparing it to last.fm
A theorem proving framework for the formal verification of Web Services Composition
We present a rigorous framework for the composition of Web Services within a
higher order logic theorem prover. Our approach is based on the
proofs-as-processes paradigm that enables inference rules of Classical Linear
Logic (CLL) to be translated into pi-calculus processes. In this setting,
composition is achieved by representing available web services as CLL
sentences, proving the requested composite service as a conjecture, and then
extracting the constructed pi-calculus term from the proof. Our framework,
implemented in HOL Light, not only uses an expressive logic that allows us to
incorporate multiple Web Services properties in the composition process, but
also provides guarantees of soundness and correctness for the composition.Comment: In Proceedings WWV 2011, arXiv:1108.208
