Nowadays, structured data such as sales and business forms are stored in data wa rehouses for decision makers to use. Further, unstructured data such as emails, html texts, images, videos, and office documents are increasingly accumulated in personal computer storage due to spread of mailing, WWW, and word processing. S uch unstructured data, or what we call multimedia documents, are larger in volum e than structured data and precious as corporate assets as well. So we need a do cument warehouse as a software framework where multimedia documents are analyzed and managed for corporate-wide information sharing and reuse like a data wareho use for structured data. We describe a prototype document warehouse system, whic h supports management of simple and compound documents, keyword-based and conten t-based retrieval, rule-based classification, SOM-based clustering, and business rules.
