An improved self organizing map using jaccard new measure for textual bugs data clustering
… measure which are Euclidean distance and Jaccard New Measure. The research results suggested that SOM has a limitation of poor performance on sparse data set. Thus, the research introduced the improved SOM algorithm by using a Jaccard NM (SOM-JNM). The SOM-JNM produced significantly better …

The effects of heuweltjies and Microhodotermes viator (Isoptera: Hodotermitidae) on invertebrate assemblages and species turnover in the succulent Karoo, Western Cape
… and species turnover was measured using the Jaccard distance. Invertebrates were more abundant on the heuweltjies, which also had distinct communities when compared to the matrix. Spiders (Aranaea) were more abundant on the heuweltjies, as were in the invertebrates emerging from the frass, …

Random amplified polymorphic DNA (RAPD) analysis of Bacillus sphaericus
… primers were examined by three coefficients, Jaccard, Dice, and simple matching. Each coefficient was able to distinguish DNA homology groups, although the relative similarity values differed. In agreement with DNA homology studies, pathogenic strains showed less than 10% similarity to …

Taxonomic and Phylogenetic Diversity of Pitcher Plant Bogs in Georgia's Coastal Plain
… Species richness, family and genus count, Jaccard Dissimilarity, phylogenetic diversity (PD), mean pairwise distance (MPD), mean nearest taxon distance (MNTD) and standardized effect sizes of MPD and MNTD were calculated for each bog. Jaccard Dissimilarity values show the bogs tend to be …

Effects of a Textile Mill Effluent and a Low Water Dam on Benthic Macroinvertebrate Community Structure of the Guadalupe River in Comal County, Texas
… upstream and downstream from Old Mill Dam. A Jaccard Coefficient of Community Similarity showed that sites upstream from the dam were more similar to the reference site than those downstream. The differences in the Jaccard Coefficients upstream and downstream from the dam were significant …
