Abstract

Process Query Systems (PQS) are a new kind of information retrieval technology in which user queries are expressed as process descriptions. The goal of a PQS is to detect the processes using a datastream or database of events that are correlated with the processes' states. This is in contrast with most traditional database query processing, information retrieval systems and web search engines in which user queries are typically formulated as Boolean expressions. In this paper, we outline the main features of Process Query Systems and the technical challenges that process detection entails. Furthermore, we describe several importance application areas that can benefit from PQS technology. Our working prototype of a PQS, called TRAFEN (for TRAcking and Fusion ENgine) is described as well.
