摘要：
A fuzzy retrieval system based on citations is proposed. A citation implies a trend of research or inheritance of knowledge. If we register a large number of documents and their citations, we will have a network of citations. Using the network of citations, one can recognize background or development of a research of a document. A citation itself is Boolean, but we define graded relations among documents through fuzzy graph theory. The membership function resulting from the retrieval is given by this relation. We discuss mathematical properties and their meaning in practical retrieval. The proposed system has been implemented on a personal computer and more than 600 documents have been registered. We will show experimental results lastly. © 1990.
