    A newspaper article is a fragmentary record of fact. For information activities in corporations it is fundamental to gather newspaper articles related to the object thema as many as possible, integrate them, analyze them, and then, create new intelligence based on them. Here in databases become effective measures. It seems essential to construct searching strategy with high recall of necessary information and understand the databases in detail when we use newspaper article databases. The cases that newspaper databases are useful for business are represented by (1) research and analysis for problem solving, (2) gathering of knowledge, and confirmation of the facts, and (3) constant observation of facts without missing any change in there. Particularly for case (1) various methods are tried for analyzing the tendency.

    The office-automation (OA) made many changes. Many documents were begun to maintained in an electronic filing system. Therefore, it is needed to establish efficient document retrieval system to extract useful information. Current document retrieval systems are using simple word-matching, syntactic-matching, semantic-matching to obtain high retrieval efficiency. On the other hand, the document retrieval systems using special hardware devices, such as ISSP, were developed for aiming high speed retrieval. Since these systems can accept a single sentence or keywords as input, it is difficult to explain searcher's request. We demonstrated document input type retrieval system, which can directly accept document as an input, and can search similar documents from document data-base.

    For obtaining the basic material to design database of space experiments, Japan Space Utilization Promotion Center has investigated the information sources, the current database services and requirements of users in space science. According to the citation analysis the existing information sources are centralized, and their lifetime is consideraly short. The survey on commercial databases show that Aerospace Database covers almost all of the document information, and JICST File as Japanese-text database has relatively wide coverage. The scope and growth of the conventional database services were estimated. It is concluded that the possible future database will not grow to large scale but have multi-files. Also an attention should be paid to complex data structure instead of data volumes. The report is intended to introduce survey methods for database building.

    The information objects have been enlarged and changed under the transition from the conventional secondary informationcentered age as well as growing age of online information serviced toward the tertiary information age in which added values to information are generated by directly accessing to the current primary information and processing the secondary information. According to the extent of its distribution and processability information is classified into pre-primary information, primary information, secondary information and tertiary information. Each is outlined in this paper. Based on the forms and use of information sources the author proposes change in information needs, change in endusers' or searchers' (information personnels) needs, method of information gathering, and the way of rendering information processed or value added.
