Process Query Systems -- Introduction


Introduction

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.

A PQS is a generic correlation engine that puts the focus on the dynamics of an environment, instead of using traditional static methods. By describing how things change over time, a PQS is able to achieve previously unseen levels of detection and correlation in environments too complex for conventional techniques.
