Abstract (in Japanese) (See Japanese page) 
(in English) In many real-life problems, we are often faced with manipulating families of sets. Manipulation of large-scale set families is one of the important fundamental techniques for web information retrieval, integration, and mining. For this purpose, a special type of binary decision diagram (BDD), called Zero-suppressed BDDs (ZDDs), is used. However there is a problem of huge required space for storing ZDDs and slow membership operations. This paper introduces DenseZDD, a compressed index for static ZDDs. Our technique not only indexes set families compactly but also executes fast membership operations. We also propose a hybrid method of DenseZDD and ordinary ZDDs to make the index dynamic.
