Method, a computer program and apparatus for analyzing symbols in a computer

摘要

The invention provides a computer-implemented method of analyzing symbols in a computer system, the symbols conforming to a specification for the symbols, in which the specification has been codified into a set of computer-readable rules; and, the symbols analyzed using the computer-readable rules to obtain patterns of the symbols by determining the path that is taken by the symbols through the rules that successfully terminates, and grouping the symbols according to said paths, the method comprising; upon receipt of a message at a computer, performing a lexical analysis of the message; and, in dependence on lexical analysis of the message assigning the message to one of the groups identified according to said paths. The invention also provides a computer programmed to perform the method and a computer program comprising program instructions for causing a computer to perform the method.

1. A method of analyzing messages in a computer system comprising:
receiving a message including symbols at a computer, including a computer readable storage medium and processor, in the computer system; performing, by the computer, a lexical analysis of the message, the lexical analysis generating a sequence of tokens based on the symbols included in the message, wherein the sequence of tokens is a syntactic sequence that enables semantic grouping of messages in accordance with a message syntax; computing a first selective message digest (SMD) for the sequence of tokens in accordance with the syntax of the sequence of tokens; and determining a cluster identifier for the first selective message digest.
