AbstractThis paper describes the importance of the development of computational tools for Natural Language Processing. Editing text in an electronic processor requires analysis of its linguistic which makes it a complex issue since there is no regularity in the interpretation of words, requiring a systematic description as close as possible of the language. Developing an electronic dictionary with this feature becomes an imminent need. This paper proposes the construction of an electronic dictionary or terminological lexicon about orchids. Due to difficulty in finding digitally cataloged papers about this topic, the development of a lexicon becomes a useful tool for experts and the general public. Data were extracted from the book “Lexicon der Orchideen”. The book contains detailed descriptions of 130 species of orchids. The lexicon’ structure was configured through a relational database and categorized through tables. Based on this relational database, future papers can be done by inserting new data and generating new reports in several formats.
