Abstract. The work on integrating sources and services in the Seman-
tic Web assumes that the data is either already represented in RDF or
OWL or is available through a Semantic Web Service. In practice, there
is a tremendous amount of data on the Web that is not available through
the Semantic Web. In this paper we present an approach to automati-
cally discover and create new Semantic Web Services. The idea behind
this approach is to start with a set of known sources and the correspond-
ing semantic descriptions and then discover similar sources, extract the
source data, build semantic descriptions of the sources, and then turn
them into Semantic Web Services. We implemented an end-to-end solu-
tion to this problem in a system called Deimos and evaluated the system
