    <Paragraph position="0"> As is generally known, the intellectual activities of human beings are very instructive in higher processing of natural language and picture patterns, especially real world picture patterns. There are three sides to intellectual  activity: (i) Recognition and understanding.</Paragraph>
    <Paragraph position="1"> (2) Thinking und inference.</Paragraph>
    <Paragraph position="2"> (3) Expression and (intellectual) action.  The system of concepts or knowledge plays an essentially important role in each activity. The base of the system is considered to be placed on those concepts formed by direct association with the real world, which are closely related with both syntactic and semantic structures of natural language. The aim of this paper is to make this system clear from the linguistic viewpoint.  There are two linguistic approaches to the analysis of the system. One is the understanding of the outline of the whole system and the other is the detailed analysis of a small part of the system. Compilation of a thesaurus is considered of the former type. Thesauruses compiled so far, 4,5 however, are not sufficient for machine processing because of the following: i. Abstraction processes of concepts As shown in Sect. 2.2, it is important to introduce abstraction processes or conceptualization processes to the system not only for its systematic analysis but also for the &amp;quot;understanding'of natural language and picture patterns. The processes are not taken into consideration in ordinary thesauruses.</Paragraph>
    <Paragraph position="3"> 2. Interrelation among concepts To know semantic interrelation among words are indispensable for natural language processing. This information is not explicitly expressed in ordinary thesauruses.</Paragraph>
