This book explores the importance of Cognitive Linguistics for specialized language within the context of Frame-based Terminology (FBT). FBT uses aspects of Frame Semantics, coupled with premises from Cognitive Linguistics to structure specialized domains and create non-language-specific knowledge representations. Corpus analysis provides information regarding the syntax, semantics, and pragmatics of specialized knowledge units. Also studied is the role of metaphor and metonymy in specialized texts. The first section explains the purpose and structure of the book. The second section gives an overview of basic concepts, theories, and applications in Terminology and Cognitive Linguistics. The third section explains the Frame-based Terminology approach. The fourth section explores the role of contextual information in specialized knowledge representation as reflected in linguistic contexts and graphical information. The final section highlights the conclusions that can be derived from this study.
