This paper sugests an extension of SPARQL to add customized similraity functions. The system has implemented as an extension of ARQ. Actually, the work is more than only similarity functions, the syntax and notion of "virtual triples" the authors propose may be viewed as a generic extension mechanism for SPARQL by external function calls. I had some personal discussions with them about whether tis is inline with the declarative semantics of SPARQL, i.e. whether the idea can be de-coupled from the deep implementation details within ARQ (since virtual triples might require a special evaluation order of patterns depending on the necessary binding patterns of virtual triples). Nevertheless a very intesting approach!
