PROBLEM TO BE SOLVED: To efficiently implement a cycle of a retrieval work process of a user and improve efficiency and quality of the retrieval work by presenting, to the user, information relating to an influence degree of a factor affecting similar document retrieval accuracy on the retrieval accuracy and measures for improving retrieval accuracy.SOLUTION: A similar document retrieval support apparatus performs an analysis relating to a factor for a set of a pair of past input documents and correct documents, associates a range of factor values with retrieval accuracy, and stores them in a table. The similar document retrieval support apparatus performs a similar factorial analysis on a new input document through computer processing, refers it to the table, and calculates the retrieval accuracy associated with a value range falling under the factorial value of the new input document. Then, through the computer processing, the retrieval accuracy and/or a divergence value from a retrieval accuracy average of all the past input documents is presented to the user. In a further preferable case, measure information for improving the retrieval accuracy is presented to the user. |
