In the equation, C and a are constants (Lotka, 1926). However, the distribution of absolute values of scientometric variables in ranks has not received much attention by researchers. Mansilla, Köppen, Cocho, and Miramontes (2007) suggested an empirical law for the rank-order behavior of journal impact factors.

This paper summarizes ongoing research in NLP (Natural Language Processing) driven citation analysis and describes experiments and motivating examples of how this work can be used to enhance traditional scientometrics analysis that is based on simply treating citations as a “vote” from the citing paper to cited paper.

A fairly large number of publications in sociology, in computer science or in information sciences, as well as in studies of collaboration in science deal with the studies of social networks with unweighted ties because measures involving unweighted ties are easier to calculate. A few studies on networks with weighted ties have been conducted. Such studies not only need more complex formulas bu...
