TL;DR
There is no added value for the clearly defined clusters but that the second-order similarity can provide an additional viewpoint for the more general clusters.

Journal of Computational and Applied MathematicsSilhouettes: A graphical aid to the interpretation and validation of cluster analysis
20,741 Citations1987Peter J. Rousseeuw
A new graphical display is proposed for partitioning techniques, where each cluster is represented by a so-called silhouette, which is based on the comparison of its tightness and separation, and provides an evaluation of clustering validity.

Empirical support is found for the claim that co-citation analysis identifies indeed subject-matter specialties of scientific research in a given period, however, different clusters may identify the same specialty, and results are far from complete concerning the identified “current work.”

199 Citations1991Robert R. Braam, Henk F. Moed +1 more
It is shown that, over a period of 10 years, continuity in intellectual base was at a lower level than continuity in topics of current research, which indicates that a series of interesting new contributions are made in course of time, without vast alteration in general topics of research.
ScientometricsUsing ‘core documents’ for detecting and labelling new emerging topics
196 Citations2011Wolfgang Glänzel, Bart Thijs
Methodology is illustrated using the example of four ISI subject categories selected from the life sciences, applied sciences and the social sciences to detect new, exceptionally growing clusters or clusters with changing topics.
ScientometricsDevelopment of a method for detection and trend analysis of research fronts built by lexical or cocitation analysis
124 Citations1994Michel Zitt, Elise Bassecoulard
The method presented here combines structural analysis and trend detection, by operating on a “thick-slice” of time, starting from co-citation or co-word analysis (applications of either type have already been carried on).
Journal of InformetricsDocument–document similarity approaches and science mapping: Experimental comparison of five approaches
91 Citations2009Per Ahlgren, Cristian Colliander
It is shown that it is possible to achieve a very good approximation of the classification by means of automatic grouping of articles, and how well the approaches agree with a ground truth subject classification of the test documents is investigated.
ScientometricsUsing ‘core documents’ for the representation of clusters and topics
86 Citations2011Wolfgang Glänzel, Bart Thijs
It is shown that core documents defined this way can be used to represent and describe document clusters and topics at different levels of aggregation.
Journal of the American Society for Information ScienceThe combined use of bibliographic coupling and cocitation for document retrieval
64 Citations1980Julie Bichteler, Edward A. Eaton
A linkage similarity measure which takes into account both the bibliographic coupling of documents and their cocitations produced improved document retrieval over a measure based only on bibliographical coupling.

61 Citations1998Alexander Kopcsa, Edgar Schiebel
A new iteration model for the calculation of co-word maps that eases the problem of bottle-necks in using statistical methods to produce mappings of reduced information in a comfortable manner is introduced.

7,12-dimethylbenz(a)anthracene binds to the aryl hydrocarbon receptor and acts as a “ ‘spatially reprogrammable’ ligand” to regulate the activity of the H2O/O2 “ receptors” in the cell.
ScientometricsThe role of core documents in bibliometric network analysis and their relation with h-type indices
33 Citations2012Wolfgang Glänzel
Examples from several disciplines in the sciences and social sciences illustrate how core vertices can be determined using this approach, and visualise how core documents are applied to represent the internal structure of the complete network or of parts of it.
ScientometricsVisualization of research fronts and knowledge bases by three-dimensional areal densities of bibliographically coupled publications and co-citations
30 Citations2012Edgar Schiebel
A method and some standardization for the detection and visualization of research fronts and knowledge bases with two and three dimensional graphics inspired by geographical maps is proposed.
ScientometricsExperimental comparison of first and second-order similarities in a scientometric context
23 Citations2011Cristian Colliander, Per Ahlgren
This article compares experimentally, using a large dataset, first-order with second-order similarities with respect to the overall quality of partitions of the dataset, where the partitions are obtained on the basis of optimizing weighted modularity.
Finding content-bearing terms using term similarities
15 Citations1999Justin Picard
Preliminary experiments with similarities computed using first-order and second-order co-occurrence seem to confirm the hypothesis that useful terms tend to be more similar to each other than to other query terms.
