    1. Input device, inputting method, information processing system, and input information managing method

      An input device which includes plural inputting units, each accepting external information, including a unit for recognizing an input time of input information accepted via each of the plural inputting means; a unit for dividing or merging the input information into a predetermined primitive analysis unit, to obtain a recognition result; a unit for estimating the input time of a unit recognition result, by using an estimating method predetermined for each of the inputting units; and a unit for collecting some of the recognition results whose estimated input times are close to one another, and outputting the collected information as ...

    2. Method and system for automatically identifying morphological information from a machine-readable dictionary

      A method and system for determining the derivational relatedness of a derived word and a base word. In a preferred embodiment, the system includes a machine-readable dictionary containing entries for head words and morphemes. Each entry contains definitional information and semantic relations. Each semantic relation specifies a relation between the head word with a word used in its definition. Semantic relations may contain nested semantic relations to specify relations between words in the definition. The system compares the semantic relations of the derived word to the semantic relations of a morpheme, which is putatively combined with the base word when ...

    3. Multiple score language processing system

      A language processing system includes a mechanism for measuring the syntax trees of sentences of material to be translated and a mechanism for truncating syntax trees in response to the measuring mechanism. In a particular embodiment, a Score Function is provided for disambiguating or truncating ambiguities on the basis of composite scores, generated at different stages of the processing.

    4. Building and updating of co-occurrence dictionary and analyzing of co-occurrence and meaning

      A co-occurrence dictionary is built through a process for calculating three kinds of co-occurrence information and a real number vector corresponding to each category. The co-occurrence dictionary is updated through a process for selecting the opposite phrase of the co-occurrence for the additional co-occurrence information and a process for calculating a real number vector corresponding to an additional word on the basis of the additional co-occurrence information. A co-occurrence analysis is effected through a process for calculating in real number the degree of the co-occurrence on the basis of the real number vectors corresponding to two categories to be checked ...

    5. Natural language processing system and method for parsing a plurality of input symbol sequences into syntactically or pragmatically correct word messages

      A Natural Language Processing System utilizes a symbol parsing layer in combination with an intelligent word parsing layer to produce a syntactically or pragmatically correct output sentence or other word message. Initially, a plurality of polysemic symbol sequences are input through a keyboard segmented into a plurality of semantic, syntactic, or pragmatic segments including agent, action and patient segments, for example. One polysemic symbol sequence, including a plurality of polysemic symbols, is input from each of the three segments of the keyboard. A symbol parsing device, in a symbol parsing layer, then parses each of the plurality of symbols in ...

    6. Database retrieval system having a natural language interface

      A database retrieval system having a natural language interface is provided. A database developer creates a knowledge base containing a structural description and semantic description of an application database from which data is to be retrieved. A database independent, canonical internal meaning representation of a natural language query is produced. An expert system accesses structural and semantic description information in the knowledge base and, in accordance with predefined rules, identifies database elements from said information that are necessary to satisfy the query represented by the internal meaning representation. A database query is generated among the database elements, enabling the retrieval ...

    7. Computer method for identifying predicate-argument structures in natural language text

      A computer method is disclosed for determining predicate-argument structures in input prose sentences of English. The input sentence, in the form of a string of words separated by blanks, is first analyzed (parsed) by a rule component that has access only to morphological and syntactic information about the words. The output of this rule component, in the form of a data structure consisting of attribute-value pairs, is then processed by the argument structure component, which consists of a set of partially ordered procedures that incorporate further linguistic knowledge. The output of these procedures is the same attribute-value structure, now enhanced ...

    8. Information retrieval system with means for analyzing undefined words in a natural language inquiry

      An information retrieval system is adapted to carry out information retrieval by entering an inquiry sentence in natural language, executing semantic analysis of the natural language inquiry sentence by a semantic analysis unit, and producing a retrieval condition from a result of the semantic analysis. The information retrieval system is provided in its semantic analysis unit with an undefined word processing unit which classifies an undefined word in the inquiry sentence in accordance with a process of producing a retrieval condition from the semantic analysis of other words contained in the inquiry sentence, the undefined word being defined as a ...
