    2. Sentence segmentation method and sentence segmentation apparatus, machine translation system, and program product using sentence segmentation method

      To provide a highly accurate sentence segmentation process in natural language processing by estimating parts of speech of words in text to be processed. Dictionary data is used to perform a sentence segmentation process on a text to be processed. If it cannot be determined through a user of the dictionary data whether the text should be broken into sentences, the parts of speech of words constituting the text are estimated and a further sentence segmentation process is performed based on the result of the estimation.

    3. Systems and methods for determining the topic structure of a portion of text

      Systems and methods for determining the topic structure of a document including text utilize a Probabilistic Latent Semantic Analysis (PLSA) model and select segmentation points based on similarity values between pairs of adjacent text blocks. PLSA forms a framework for both text segmentation and topic identification. The use of PLSA provides an improved representation for the sparse information in a text block, such as a sentence or a sequence of sentences. Topic characterization of each text segment is derived from PLSA parameters that relate words to "topics", latent variables in the PLSA model, and "topics" to text segments. A system ...

    14. 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. In some cases, this alternative sequence is formed through inflectional morphology, which identifies a different lexical form for a word identified by the segment. In some cases, the alternative sequence represents an orthographic variant of a word identified by ...

    15. 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 ...
