Natural-Language Parser for PBEM

A computer program called “Hunter” accepts, as input, a colloquial-English description of a set of policy-based-management rules, and parses that description into a form useable by policy-based enterprise management (PBEM) software.

PBEM is a rules-based approach suitable for automating some management tasks. PBEM simplifies the management of a given enterprise through establishment of policies addressing situations that are likely to occur. PBEM provides a way of managing configurations of network elements, applications, and processes via a set of high-level rules or business policies rather than managing individual elements. Thus, PBEM enables abstraction of the capabilities of the individual elements and switching of control to higher levels.

Development of a system that understands colloquial English is an extremely difficult problem. Because most people do not write perfect English, such a system must be very robust in order to understand what has been written. Hunter is such a system. Recognizing that all possible dialects and variants thereof cannot be anticipated in advance, Hunter was developed to have a unique capability to extract the intended meaning instead of focusing on parsing the exact ways in which individual words are used.
