Title

¬A representation of complex events and processes for the acquisition of knowledge from texts

Source

Knowledge-based systems. 10(1998) no.4, S.237-251

Abstract

Proposes temporal event hierarchies as a technique to represent knowledge in texts describing processes. The representation is that which a program, without prior knowledge about these processes, will be able to acquire by reading a description of a process. The representation is intended to be used by programs that acquire knowledge from texts. This representation is viewed as a bridge between the English description of a biological system and deeper representations of systems such as those proposed by qualitative physics and model-based reasoning. The representation is based on temporal relationships that are used to index and organise knowledge about biological systems in a hierarchy of events. Explains several reasoning methods that the proposed representation permits. The event centred representation is also related to object centred representations. Explains algorithms for the automated construction of the event hierarchies
