A terminological "journey" in the Grey Literature domain

"It is by means of terms that the expert usually transfer their knowledge and again through terms scientific communication reaches the highest effectiveness. Therefore we can assert that terminology - in the sense of a set of representative and domain-specific units - is necessary for representing and connecting specialized fields as well as any attempt to represent and/or transfer scientific knowledge requires, more or less extensively, the use of terminology." (Cabré, 2000). "When we read the articles or papers of a particular domain, we can recognize some lexical items in the texts as technical terms. In a domain where new knowledge is generated, new terms are constantly created to fulfill the needs of the domain, while others become obsolete. In addition, existing terms may undergo changes of meaning..." (Kageura K., 1998/1999). Specialized lexicons are made up of the terms which are specific to each field of knowledge, «a subset which is distinct but not separated from the common language» (Cassese, 1992): it is usually difficult to extract the relevant domain-specific terminology, meaning to discern terms which belong to a specialized glossary from those belonging to the common dictionary. The interest in the study of terminology and the "truth" contained in the above definitions has led us to make a "journey" in the Grey Literature (GL) domain in order to offer an overall vision on the terms used and the links between them. Within this scenario, the work analyzes a corpus constituted of the entire amount of full research papers published in the GL conference series over a time-span of more than one decade (2003-2014) with the aim of creating a terminological map of relevant words in the various GL research topics. "... corpora used to extract terminological units can be further investigated to find semantic and conceptual information on terms or to represent conceptual relationships between terms. (Bourigault D. et al., 2001). Another interesting inquiry is the terminology used in the GL conferences for describing the types of documents which can be detected (Pej?ová P. et al., 2012).
