摘 要：In this technical report we describe methodology for building information extraction (IE) rules. Rules are usually developed by experts and are widely used in knowledge-based IE systems. They consist of two parts: the left-hand side (LHS) of a rule is a template that matches a certain syntactico-semantic structure (SSS) and the right-hand side is an action that is executed when LHS template is matched against a particular text fragment. In the report we describe the process of building a more complex LHS part (template). This methodology was used for developing the information extraction system that extracts business events from news articles written in Russian language.
