The analysis of subjects contained in the Documents is one of the most important problems in the Document Retrieval System. There were methods in which role-indicators or links or weights are attached to the Documents in order to raise retrieval efficiency. From the experimental data in the past, it is well known that the system with role-indicators is at a disadvantage in the recall-factor. But the cause of such faults are the following three ; 1) the property of role-indicator itself. 2) the ambiguity of rules which assign role-indicator to words in the Documents. 3) wrong assignment of role-indicator by the intereference of the man. We organize the role-indicator system which is quite different from usual one, and design the algorithm of automatically indexing documents by words with role-indicators and tried a few experiments and also considered the retrieval system suitable to this automatic subjects recognition system.
