KoTOvsKY, LAUHA, and GENTNER, DEDRE. Comparison and Categorization in the Development of Relational Similarity. CHILD DEVELOPMENT, 1996, 67, 2797-2822. 4 experiments investigated the development of children's ability to recognize perceptual relational commonalities such as symmetry or monotonicity. In Experiment 1, 6and 8-year-olds were able to recognize higherorder relational similarity across...

Current similarity measures for virtual screening are based on the use of molecular fingerprints and the Tanimoto coefficient. This paper describes two ways in which one can increase the effectiveness of similarity-based virtual screening: using similarity coefficients other than the Tanimoto coefficient for the comparison of molecular fingerprints; and using a graph-theoretic similarity measur...

We present our approach to defining similarity between software artifacts and discuss its potential exploitation in software reuse by analogy. We first establish properties of similarity which support its role in retrieving and mapping software descriptions. Then we develop a systematic basis for comparison within a fairly general conceptual modelling framework, whereby comparable elements of t...

Flow cytometry is a common technique for quantitatively measuring the expression of individual molecules on cells. The molecular expression is represented by a frequency histogram of fluorescence intensity. For flow cytometry to be used as a knowledge discovery tool to identify unknown molecules, histogram comparison is a major limitation. Many traditional comparison methods do not provide adeq...

The way we model semantic similarity is closely tied to our understanding of linguistic representations. We present several models of semantic similarity, based on di ering representational assumptions, and investigate their properties via comparison with human ratings of verb similarity. The results o er insight into the bases for human similarity judgments and provide a testbed for further in...

Tree comparison is ubiquitous in many areas. The simplest way for tree comparison is to define a pairwise distance measure. In a more refined comparison, one can establish a mapping between similar parts in two trees according to certain similarity measure. The best match problem for rooted leaf-labeled trees has been studied in the literature. However, no result has been found for the best mat...

Carrying out similarity and analogy comparisons can be modeled as the alignment and mapping of structured representations. In this article we focus on three aspects of comparison that are central in structure-mapping theory. All three are controversial. First, comparison involves structured representations. Second, the comparison process is driven by a preference for connected relational struct...

in order to study the genetic diversity among some male pistachio genotypes,16 male pistachio genotypes and 8 female pistachio cultivars were selected from iranian pistachio research institute (ipri). 12 rapd primers were used which totally produced 65 bands that among them 48 bands were polymorphic and 17 bands were monomorphic. cluster analysis based on similarity matrix and jaccard similarit...

Dis) similarity measure is a significant component of vector model. In content based image retrieval the compatibility of (dis)similarity measure and representation technique is very important for effective and efficient image retrieval. In order to find a suitable dis-similarity measure for a particular representation technique experimental comparison is needed. This paper highlights some of t...

In this paper we investigate the role of rhythmic similarity as part of melodic similarity in the context of Folksong research. We define a rhythmic similarity measure based on Inner Metric Analysis and apply it to groups of similar melodies. The comparison with a similarity measure of the SIMILE software shows that the two models agree on the number of melodies that are considered very similar...
