Title:
QUERY PROVIDING DEVICE, QUERY PROVIDING METHOD AND QUERY PROVIDING PROGRAM
Document Type and Number:
Japanese Patent JP2018022214
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a query providing device, query providing method, and query providing program that can broaden a range of an additional query to be proposed.SOLUTION: A query providing device comprises: a reception unit that receives an input of a first query; a first extraction unit that extracts, from a history of the query preliminarily stored in a storage unit, a second query allowing an amount of characteristic similar to an amount of characteristic of the first query received by the reception unit to be obtained; a second extraction unit that extracts, from the history of the query, a word appearing together with the second query extracted from the first extraction unit; and a determination unit that determines an additional query to be suggested following the first query of the word extracted by the second extraction unit on the basis of information about the appearance of the word extracted by the second extraction unit.SELECTED DRAWING: Figure 1
