    • A computer-based method for identifying patterns in computer text using structures defining types of patterns which are to be identified, wherein a structure comprises one or more definition items, the method comprising assigning a weighting to each structure and each definition item; searching the computer text for a pattern to be identified on the basis of a particular structure, a pattern being provisionally identified if it matches the definition given by said particular structure; in a provisionally identified pattern, determining those of the definition items making up said particular structure that have been identified in the provisionally identified pattern; combining the weightings of the determined definition items and optionally, the weighting of the particular structure, to a single quantity; assessing whether the single quantity fulfils a given condition; depending on the result of said assessment, rejecting or confirming the provisionally identified pattern.
    • 一种基于计算机的方法,用于使用定义要识别的模式类型的结构来识别计算机文本中的模式,其中,结构包括一个或多个定义项,所述方法包括为每个结构和每个定义项分配权重; 根据特定结构搜索要识别的模式的计算机文本,如果它符合由所述特定结构给出的定义,则临时识别模式; 以临时确定的模式,确定构成所述特定结构的定义项中已经以临时识别的模式被识别的模式; 将所确定的定义项目的权重和可选的特定结构的权重组合到单个数量; 评估单一数量是否满足给定条件; 取决于所述评估的结果,拒绝或确认临时识别的模式。

    • An apparatus for processing a sequence of tokens to detect predetermined data, wherein each said token has a token type, and the predetermined data has a structure that comprises a predetermined sequence of token types, including at least one optional token type. The apparatus comprises a processor arranged to: provide a tree for detecting the predetermined data, the tree comprising a plurality of states, each said state being linked with at least one other state by a respective condition, the arrangement of linked states forming a plurality of paths; and compare the token types of the sequence of tokens to respective conditions in the tree to match the sequence of tokens to one or more paths in the tree, wherein the predetermined data can be detected without using an epsilon reduction to take account of said at least one optional token type.
