Abstract： [Purpose/significance] Thesauri associative relationships play an important role in indexing and information retrieval, classification and property definition of associative relationships have important significances in information organization.[Method/process] This paper analyzed the characteristics of interspecies relationships in ecology and thesauri associative relationships, and established the link between them. Then, through the combination of different characteristics, it classified the associative relationships by interspecies relationships. Finally, it discussed the construction of associative relationship from the perspective of interspecies relationship.[Result/conclusion] The associative relationships can be classified into four kinds of interspecies relationships, including predation, symbiosis, competition, parasitism. Different associative relationships have different properties, and the classification of associative relationships can provide a new way for the construction of associative relationship.

Abstract： [Purpose/significance] In order to enhance the practicability of thesaurus, it is necessary to constantly update new terms in the field to thesaurus. In the process of updating and maintenance, we should explore the distribution characteristics of new terms from the perspective of time and frequency, which can provide reference for the method of discovering new terms.[Method/process] Based on the relevant characteristics of the new terminology, combined with the development distribution of the corresponding document frequency at time point and period, through the relevant statistical analysis, the distribution of terminologies in different development periods is studied, especially the characteristics of terminologies from the beginning to the maturity.[Result/conclusion] It is proved that the new terminology is generally in the growth stage of terminology. When the candidate new terminology keeps positive growth trend for more than a certain number of years, it is considered that the term has all novelty, time persistence and terminological features. Based on the distribution characteristics, the article selects a subject area to discover its new terminology. According to the judgment of the expert, the method has a high accuracy rate in the judgment of new term, and can effectively identify the low frequency words which are more occupied in practical applications.

Abstract： [Purpose/significance] By introducing the principles and methods of ecology into the study of knowledge organization system, the functions and actions of knowledge organization system can be brought into full play. [Method/process] Based on the research results of ecology, the principles and methods of ecology are introduced into the construction and application of the knowledge organization system. The biological individual corresponds to the concept individual, the species population and the concept correspond, the biological community and the vocabulary correspond, the biological environment corresponds to the literature environment and on the basis of the complete and consistent correspondence of the structure and function, the working principle and method of the knowledge organization system are studied. [Result/conclusion] The framework of the knowledge organization ecosystem is refined and perfected, and the main contents of each level are analyzed and summarized in the four aspects, including the concept instance, the concept population, the concept community (vocabulary) and the ecosystem.
