Using a mathematical method, a scientific citation analysis of the literature on boron nitride has been performed it allows a qualitative and quantitative analysis of BN-related information [1]. 

In this chapter a systematic review of literature in form of a co-citation analysis is presented. The aim of this chapter is to depict existing major streams of literature and show that there is hardly any existing research on embedded lead users. 

My co-citation analysis proceeds in 3 steps, which will be described in the course of this chapter (Chen et aL 2010] data collection, data preparation (construction and visualization of matiiz], identification and interpretation of clusters. 

In the next phase, the co-dtation matrix needed to be constructed and visualized. For the construction of the matrix, references were either extracted automatically (ISl) or manually (EBSCO) for each publication included in the analysis. As the entries in die reference lists included different citation styles or misspellings, all references needed to be normalized. I then excluded those references which were not part of the dataset, i.e. those which were not included in the 111 papers. By this procedure many references were excluded from the analysis, but the matrix could be constructed more effidendy. The focus of the citation analysis was rather on the connection of papers within the field of user innovation than on the epistemological foundations thereof (cf. Raasch et al. forthcoming). Thus it was sufficient to include only papers that focus on the topic of user innovation, and not its intellectual ancestry. In the next step I constructed the citation matrix. This 111x111 matrix included all articles and indicated which other publications from the pool were cited. Publications that were not died at all and did not co-dte others were deleted from the matrix, as they were obsolete for the analysis. This yielded a list of 100 publications. In the last step the co-citation matrix was built I exduded papers that were not co-cited (46 publications) from the analysis. The doseness measure used in this study (CoCit score) was calculated. The CoCit score of two documents (A and B) ranges from 0 to 1 and can be calculated as follows (Gmiir 2003) ...

On the subject of how much impact computational chemists have on the scientific community, a quantifiable measure of a person s contribution to a scientific field, besides the physical mass of one s publications, is the number of citations to a person s papers. It is usually assumed that the more popular a new method, or the more valuable new data, the more the work will be used and cited by subsequent authors. Thus, the number of citations has become one of many measures of the scientific community s assessment of the merits of a person s work. However, critics point to various faults with citation frequency data. For example, some scientists can have a profound and lasting influence on a field of research and still not be the most highly cited. Some scientists can be highly cited and not have much influence beyond their own sphere of interest. Self citation can inflate numbers. Another caveat about citation rankings arises from how the ISI database stores a person s identity. If two or more people share the same last name and initial(s), then they could be miscounted as the same person. Conversely, if an author uses two initials in some papers and only one initial in other papers, then that person could be counted as two different individuals. Furthermore, if a person s name changes or if a person s name is misspelled or spelled inconsistently in citations, that person s citations could look misleadingly low. Fortunately, most of the well-known computational chemists have individualistic names. Further discussion of the issues associated with citation analysis can be found elsewhere. Citation frequency in the field of computational chemistry was earlier analyzed in this book series. ... 

The question of whether and how knowledge may be subject to measurement is one of notorious difficulty. We shall therefore content ourselves with the simpler, but not simple, question of measuring the influence of published research as reflected by its mention in the footnotes (citations) of other published work. In recent years applications of citation analysis to the study of science have achieved a high level of technical sophistication. Proponents of the technique contend that it promises to yield quantitative indicators of precise cognitive and social changes in scientific specialities. ...
