Abstract: A non-transitory computer-readable recording medium storing an information processing program for causing a computer to execute processing including: extracting named-entities that include a hypernym from a document, the document being any one of a search query or document data that is regarded as an analysis object; specifying a modifier character stung that modifies the extracted hypernym from the document; generating conditions to be applied when a knowledge graph is searched for a hyponym relevant to the extracted hypernym, based on a type and content of the named-entities included in the specified modifier character string; searching the knowledge graph for the hyponym in accordance with the generated conditions; and associating the extracted hypernym with the hyponym found in the search.

Abstract: A retrieval device specifies the chemical structure of a compound indicated by a compound name included in an input document. The retrieval device totalizes, for each substructure of the chemical structure, the number of substructures included in the input document. The retrieval device generates a substructure vector of the input document based on the substructure and the number. The retrieval device outputs one or more documents similar to the input document from a plurality of documents including a stored compound name based on comparison between the substructure vector of the input document and each substructure vector of the documents.

Abstract: Plural words which partially match the accepted character string data are extracted from a words dictionary. When the numeric character string contained in the accepted character string data has a numeric character string portion for which a partially matching word can not be extracted, a similar word which is similar to the numeric character string portion are extracted from the words dictionary. Based on the extracted words and the extracted similar word, words constituting the accepted character string data are specified, and the pronunciations of the plural extracted words are specified and numerical pronunciation rules are created. The pronunciation of the numeric character string is set in accordance with thus created numerical pronunciation rules. Based on the pronunciations of the specified words and the pronunciation of the similar word including the specified pronunciation of the numeric character string, the pronunciation of the character string data is specified.

Abstract: In the voice synthesizer, which obtains a voice by emphasizing a specific part of a sentence, an emphasis degree deciding unit extracts a word or a collocation to be emphasized from among respective words or respective collocations on the basis of an extracting reference with respect to the each word or the each collocation included in a sentence and deciding an emphasis degree of the extracted word or the extracted collocation. An acoustic processing unit synthesizes a voice having an emphasis degree that is decided by the emphasis degree deciding unit provided to the word to be emphasized or the collocation to be emphasized. Whereby the emphasized part of the word or the collocation can be obtained automatically on the basis of the extracting reference such as a frequency of appearance and a level of importance of the word or the collocation, further, improves an operation-ability.
