Document Type and Number:
WIPO Patent Application WO/2018/179355
Kind Code:
A1
Abstract:
The present invention is an information processing device for learning parameters for a converter that converts queries in a natural language to query expressions in a formal language, the information processing device comprising: an input receiving unit that receives an input of a pair consisting of a query in a natural language and a correct reply which is an appropriate output for the query; a positive example condition generating unit that generates, on the basis of formal language-related data stored in a search database, at least one or more conditions to be satisfied by a formal language which is inputted when the search database is searched for the correct reply; a query expression generating unit that generates a query expression in the formal language corresponding to the query by using the parameters for the converter such that any of the conditions is satisfied; a reply acquiring unit that acquires a reply to the query on the basis of searching of the search database performed with use of the generated query expression; and a parameter updating unit that updates the parameters for the converter such that, when the reply matches the correct reply, the query is preferentially converted to the query expression generated from the query. The information processing device efficiently performs machine learning of the converter even when the number of expressions in a formal language is large.
