  • Publication number: 20180129478
    Abstract: A computer-implemented method and computing device are provided for generating a formal specification of a function. The method includes extracting a set of words from requirements of the function. The method further includes translating the set of words to a set of specification fragments. The method also includes converting the set of the specification fragments to a set of production rules. The method additionally includes constructing multiple prospective specifications from the set of production rules taking into account a syntax of the formal specification. The method further includes validating each of the multiple prospective specifications using input-output examples. The method also includes generating the formal specification of the function from validated ones of the multiple prospective specifications.

  • Publication number: 20180129734
    Abstract: A method for answering consecutive questions, using a system which can access a database is provided. The method includes retrieving a questioner identifier associated with a questioner in response to receipt of a question from the questioner. The method also includes obtaining, using the questioner identifier, a history on class labels which were assigned to questions made by the questioner in the past and choosing a class label among the class labels in the history. The method further includes obtaining a list of keywords of the question and judging whether or not each keyword in the keyword list matches a representative keyword in any node among one or more nodes which exist in a hierarchy level in the database, or matches a synonym of the representative keyword.

  • Publication number: 20170278509
    Abstract: A method, for testing words defined in a pronunciation lexicon used in an automatic speech recognition (ASR) system, is provided. The method includes: obtaining test sentences which can be accepted by a language model used in the ASR system. The test sentences cover words defined in the pronunciation lexicon. The method further includes obtaining variations of speech data corresponding to each test sentence, and obtaining a plurality of texts by recognizing the variations of speech data, or a plurality of texts generated by recognizing the variation of speech data. The method also includes constructing a word graph, using the plurality of texts, for each test sentence, where each word in the word graph corresponds to each word defined in the pronunciation lexicon; and determining whether or not all or parts of words in a test sentence are present in a path of the word graph derived from the test sentence.

  • Patent number: 9390117
    Abstract: The present invention provides a method of extracting a transformation pattern as an approximate pattern expression. In the process of transforming the sets of input strings to at least one pattern expression, the transformation pattern transforming the sets of input strings to the pattern expression. The method includes: 1) preparing one structure including multiple nodes each representing a state and multiple edges each representing a transition; 2) generating a first reduced structure by removing at least one state in one structure from one structure and by merging at least two edges including an edge associated with the removed state in the one structure; 3) generating a first approximate pattern expression based on the first reduced structure; and 4) presenting the first approximate pattern expression.

  • Patent number: 9208590
    Abstract: Techniques are disclosed for effectively reflecting a manipulation of an object in graph data. In one example, a method enables a manipulation performed on an object as an image of a mapping of at least a part of graph data including nodes and edges to be reflected in the graph data. The method includes the step of specifying, from among nodes in the graph data that are related to the object being modified by the manipulation, a shared node that may be related to another object as well, and the step of reflecting the manipulation in the graph data while preventing the shared node from being modified.

  • Patent number: 8943084
    Abstract: To provide a method, program, and system for converting graph data to a data structure that enables manipulations in various applications to be reflected in the original graph data. The method uses at least one graph matching pattern to convert at least a part of graph data including nodes and edges to a data structure as an image of a homomorphism thereof. A pattern is provided which includes one representative node variable having a first constraint that at most one node in the graph data matches the representative node variable; the node is prohibited from matching a node variable in another pattern. The method includes the step of performing matching between the graph data and the pattern to obtain a matching result that does not violate constraints including the first constraint, and the step of generating a data structure corresponding to the matching result that does not violate the constraints.
