|Abstract:||The emergence of information extraction (IE) oriented pattern engines has been observed during the last decade. Most of them exploit heavily finite-state devices. This paper introduces EXPRESS – a new extraction pattern engine, whose rules are regular expressions over flat feature structures. The underlying pattern language can be seen as a blend of two previously introduced IE oriented pattern formalisms, namely, JAPE, used in the widely known GATE system, and the unification-based XTDL formalism used in SProUT. A brief and technical in nature overview of EXPRESS, its pattern language and the pool of its native linguistic components is given. Further, the implementation of the grammar interpreter is addressed too.|
