Abstract
After studying the relations between two words(nouns) that constitute a compound term, the relation between corresponding concepts discussed. The impossibility of having a conjunction between two concepts that have no common feature causes inconvenience in the application of concept theory to information retrieval problems. Another kind of conjunctions, different from that by co-occurrence, is proposed and characteristics of this conjunction is studied. It revealed that one of new ones has the same character with colon combination in UDC. The possibility of having three kinds of conjunction including Wsterian concept conjunction is presented. It is also discussed that subdivisions can be replaced by new conjunctions
