- Abstract
- Ahlgren, Jarneving, and. Rousseau review accepted procedures for author co-citation analysis first pointing out that since in the raw data matrix the row and column values are identical i,e, the co-citation count of two authors, there is no clear choice for diagonal values. They suggest the number of times an author has been co-cited with himself excluding self citation rather than the common treatment as zeros or as missing values. When the matrix is converted to a similarity matrix the normal procedure is to create a matrix of Pearson's r coefficients between data vectors. Ranking by r and by co-citation frequency and by intuition can easily yield three different orders. It would seem necessary that the adding of zeros to the matrix will not affect the value or the relative order of similarity measures but it is shown that this is not the case with Pearson's r. Using 913 bibliographic descriptions form the Web of Science of articles form JASIS and Scientometrics, authors names were extracted, edited and 12 information retrieval authors and 12 bibliometric authors each from the top 100 most cited were selected. Co-citation and r value (diagonal elements treated as missing) matrices were constructed, and then reconstructed in expanded form. Adding zeros can both change the r value and the ordering of the authors based upon that value. A chi-squared distance measure would not violate these requirements, nor would the cosine coefficient. It is also argued that co-citation data is ordinal data since there is no assurance of an absolute zero number of co-citations, and thus Pearson is not appropriate. The number of ties in co-citation data make the use of the Spearman rank order coefficient problematic.

- Abstract
- When applying for patents, companies should consider performing patent portfolios as a means of integrating their patent strategy to shape their overall business strategy. This is an important issue for any company in pursuit of enhanced operational performance because the whole raison d'être behind the application of patents is the anticipation of achieving maximum competitive advantage. A prerequisite for such a company is a decision analysis model of patent portfolios because this has the added advantage of being readily applicable to the evaluation of the quality of its competitors' portfolios; thus, by understanding both itself and its competitors, a company can attain a superior position. To demonstrate this, we examine patent priority networks (PPNs) formed through patent family members and claimed priority patents, performing a model of patent portfolio analysis and then going on to determine the algorithms. We suggest that information retrieved from this network can provide a useful reference tool for decision-making by company CEOs, CTOs, R&D managers, and intellectual property managers.

- Abstract
- S. R. Ranganathan (1892-1972) has been called the father of the Indian Library movement. He developed the revolutionary Colon Classification (CC), which was published in seven editions from 1928 to 1987. The evolution of the classification through the editions is discussed. The unique features of the CC are described, including the idea, verbal, and notational planes. Tools for designing and evaluating a system are enshrined in his 55 canons, 22 principles, 13 postulates, and 10 devices. Semantic and syntactic relations are enshrined in his PMEST facet formula, fitted with rounds and levels of facets, and other principles, such as the famous wall-picture principle, for citation order of facets. Briefly explained are facet analysis and number building with its notational base of 74 digits. The entry concludes with a discussion of the extent of use of the CC, its enduring contribution to the science of classification, and its future.
