PROBLEM TO BE SOLVED: To detect an expression having insufficiency in refinement (refining target expression) for each appropriate range that constitutes an input document.SOLUTION: A refinement insufficiency detection device 11 includes: a document division detecting section 114 for dividing an input document into one or more partial documents by taking positions of a specific expression as reference; a co-occurrence presence checking section 115 for setting the specific expression as a co-occurrence region when the specific expression is registered in advance as a co-occurrence region, and setting the partial document as the co-occurrence region when the specific expression is not registered, in the concerned partial document among the one or more partial documents divided by the document division detecting section 114; and a refinement insufficiency detection section 116 for determining, in the concerned partial document, whether a first expression and a second expression associated to the first expression, which are registered in advance, are present or not in the co-occurrence region set by the co-occurrence presence checking section 115, and detecting the first expression as an expression having insufficiency in refinement when the second expression is not present. |
