PURPOSE: A retrieval performance measurement method for a key fact based text retrieval model is provided to calculate a weight value on a document and a query language and give the document a priority based on a similarity between the document and the query. CONSTITUTION: A retrieval performance measurement method for a key fact based text retrieval model comprises the steps of extracting key words from a set of documents and queries(S01), asking if setting a variable value of retrieval performance assessment elements on the extracted result(S02), if the answer is positive, giving the variable value of retrieval performance assessment elements on a new document size, a key fact frequency within the document, and a key fact weight constant(S03), making a document and a query vector including the assessment variable value(S04), calculating a key fact weight value of the document and the query by a key fact weight equation(S05), obtaining a retrieval performance result of the key fact based text retrieval model for searching for an optimal retrieval model according to characteristics of a retrieval target document domain(S06), giving the documents a priority number(S07), and assessing the retrieval model(S08).
