    Abstract
    A main goal of recent studies in semantics is to integrate into conceptual structures the models of representation used in linguistics, logic, and/or artificial intelligence. A fundamental problem resides in the need to structure knowledge and then to check the validity of constructed representations. We propose associating logical properties with relationships by introducing the relationships into a typed and functional system of specifcations. This makes it possible to compare conceptual representations against the relationships established between the concepts. The mandatory condition to validate such a conceptual representation is consistency. The semantic system proposed is based an a structured set of semantic primitives-types, relations, and properties-based an a global model of language processing, Applicative and Cognitive Grammar (ACG) (Desc16s, 1990), and an extension of this model to terminology (Jouis & Mustafa 1995, 1996, 1997). The ACG postulates three levels of representation of languages, including a cognitive level. At this level, the meanings of lexical predicates are represented by semantic cognitive schemes. From this perspective, we propose a set of semantic concepts, which defines an organized system of meanings. Relations are part of a specification network based an a general terminological scheure (i.e., a coherent system of meanings of relations). In such a system, a specific relation may be characterized as to its: (1) functional type (the semantic type of arguments of the relation); (2) algebraic properties (reflexivity, symmetry, transitivity, etc.); and (3) combinatorial relations with other entities in the same context (for instance, the part of the text where a concept is defined).

    Abstract
    Building reference terminology (i.e. conceptual structure: identification of terms or concepts names related to a specific field of knowledge and the logico-semantic relations they hold) from extensive textual data is not a simple task when the designer has to examine a new field of knowledge. We observe special problems due to the fact that inter-concept relations are not very often specified in Knowledge-Based Systems, Thesaurus Construction (Documentary Databases, Information Retrieval) and Terminological Database construction, etc. For that reason, it is sometimes difficult to validate the constructed representation. In this proposal, we associate properties to relations by introducing the relations into a system of specifications. Therefore, it is possible to check, not the validation of the constructed conceptual structure, but its coherency in comparison to the established relations between the concepts, which is the necessary condition to validate a semantic representation

    Abstract
    This paper will survey the capacity of natural language processing (NLP) systems to identify terms or concept names related to a specific field of knowledge (construction of a reference terminology) and the logico-semantic relations they entertain. The scope of our study will be limited to French language NLP systems whose purpose is automatic terms identification with textual area-grounded terms providing access keys to information
