Although the topological index does not uniquely correspond to the individual structure of a graph, it roughly represents the topological nature of the graph. Examples are given for using the topological index as a first sorting device for coding and retrieving structures, especially of fused polycyclic systems. (14 references) (Author/NH)

Reports on a continuing investigation of intertextual networks. Describes how intertextual networks can be modeled as directed graphs and extends this to matrix representations. Discusses topological index values of these networks and speculates how topological index values might be used in the estimation of retrieval values in information…

The 7th International Conference on Education Data Mining held on July 4th-7th, 2014, at the Institute of Education, London, UK is the leading international forum for high-quality research that mines large data sets in order to answer educational research questions that shed light on the learning process. These data sets may come from the traces…
