Abstract:
1. A method for recognizing a named entity included in Chinese character strings, comprising the steps of: recognizing candidate named entities included in the Chinese character strings by a gradual recognizer; extracting the recognized candidate named entities by a refusal recognizer based on all global features of one or more Chinese characters or words contained in the candidate named entities, wherein the global features indicate information of the one or more Chinese characters or words including context, length, part-of-speech, and type of the one or more Chinese characters or words; testing said candidate named entities by using said global features; and if a score of the testing is larger than a predetermined threshold, accepting said candidate named entity, otherwise, refusing the recognition thereof; further comprising a step of forming the candidate named entities recognized by the refusal recognizer as a lattice on which each candidate named entity is attached with a refusal recognition score, and a step of searching for a path having a maximum sum of the refusal recognition scores on the lattice as an optimal path, and selecting the candidate named entities on the optimal path as the final result.
