    3. Method for segmenting non-segmented text using syntactic parse

      Embodiments of the present invention provide a method and apparatus for segmenting text by providing orthographic and inflectional variations to a syntactic parser. Under the present invention, possible segments are first identified in the sequence of characters. At least two of the identified segments overlap each other. For at least one of the segments, an alternative sequence of characters is identified.

    4. Method for improving results in an HMM-based segmentation system by incorporating external knowledge

      A Hidden Markov model is used to segment a data sequence. To reduce the potential for error that may result from the Markov assumption, the Viterbi dynamic programming algorithm is modified to apply a multiplicative factor if a particular set of states is re-entered. As a result, structural domain knowledge is incorporated into the algorithm by expanding the state space in the dynamic programming recurrence. In a specific example of segmenting resumes, the factor is used to reward or penalize (even require or prohibit) a segmentation of the resume that results in the re-entry into a section such as Experience ...

    10. Chinese word segmentation apparatus

      A Chinese word segmentation apparatus relates to processing of a Chinese sentence input to a computer. A character-to-phonetic converter of the segmentation apparatus initially converts a Chinese sentence into a phonetic symbol string while referring to a character phonetic dictionary and a ductionary for characters with different pronunciations. Thereafter, a candidate word-selector refers to a system dictionary to retrieve all of the possible candidate characters or words in the phonetic symbol string and relevant information, such as frequency of use, using the phonetic symbols as indexing terms. Unfeasible candidate characters or words are discarded. Subsequently, an optimum candidate character string-decider ...
