Abstract

The invention provides a similar document retrieval auxiliary device and a similar document retrieval auxiliary method. The extent of the impact exerted on retrieval precision by an essential factor affecting similar document retrieval precision and information concerning countermeasures for improving retrieval precision are shown to a user, and therefore the retrieval work of the user can cyclically run in a highly-efficient manner, and the efficiency and quality of the retrieval work can be improved. Based on a right set of previous input documents and right answer documents, the essential factor is analyzed, and a correspondence relation is established between a value range of the essential factor and retrieval precision and is stored in a table. Through computer processing operation, newly input documents are subjected to the same essential analysis operation, retrieval precision corresponding to the value range which conforms with the essential factor value of the newly input documents is calculated based on comparison with the above table. Then, through computer processing, the retrieval precision and / or an average deviation value compared with the whole retrieval precision of the previous input documents is shown to the user. In a more ideal condition, information of countermeasures for improving the retrieval precision is shown to the user.
