To identify keywords with high semantic value in the thematic content of a scientific paper the Goffman's transition Point is applied. A total of 1,644 different words were identified in the text. These words were arranged in descending order of frequency to explore four possibilities. In the first examination both, functional words and words with high semantic value were taken into account. In the second examination, the functional words were removed; and in the third examination both functional words as well as words with high semantic content, were lemmatized. In the fourth examination only functional word were eliminated. The result shows the identification of specific keywords.

Keywords : Zipf's law; Goffman's Transition Point; Bibliometrics; Scientometrics; Infometrics.
