Ontology matching has emerged as a crucial step when information sources are being integrated. Hence, ontology matching has attracted considerable attention in both academia and industry. Clearly, as information sources grow rapidly, manual ontology matching becomes tedious, time-consuming and leads to errors and frustration. Thus the need for automated and semi-automated approaches becomes inc...

In this paper, we propose the use of metadata to define the perceptual weight of semantically meaningful regions in video frames for video quality assessment. The proposed approach is evaluated using the structural similarity (SSIM) index metric and a comparison is made with both the unweighted approach and the luminance-based weighted approach. Experimental results demonstrate that the propose...

Localization and segmentation of Optic Disk (OD) is an important prerequisite for automatic detection of Diabetic Retinopathy (DR) from digital retinal fundus images. Considerable research has been done to isolate OD with varying degrees of success but on a limited number of images. In this paper we propose a novel algorithm based on Independent Component Analysis (ICA) coupled with a modified ...

This work aims to explore whether the sustainability of scientific collaboration including collaboration duration and collaboration times can be predicted. For this purpose, we propose a series of features including structural similarity indices, authorship properties, and research interests. Experimental results on a real-world dataset show that our proposed model outperforms baseline model by...

This paper describes the first shared task on Taxonomy Extraction Evaluation organised as part of SemEval-2015. Participants were asked to find hypernym-hyponym relations between given terms. For each of the four selected target domains the participants were provided with two lists of domainspecific terms: a WordNet collection of terms and a well-known terminology extracted from an online publi...

The objective of this study is to analyze the comparison, through their results, of two distinct methods applied to aligning two representations of anatomy. The same versions of FMA and GALEN were aligned by each method. 2199 concept matches were obtained by both methods. For matches identified by one method only (337 and 336 respectively), we analyzed the reasons that caused the other method t...

Spontaneously retrieving analogies from presented problem data is an important phase of analogical reasoning, influencing many related cognitive processes. Existing models have focused on semantic similarity, but structural similarity is also a necessary requirement of any analogical comparison. We present a new technique for performing structure based analogy retrieval. This is founded upon de...

This paper describes on a developmental system WebPACADE which is an extended version of a deductive database system PACADE for the analysis of protein 3D structure. It enables structural similarity searches on various proteins in the level of secondary structure. Results of a similarity search can be displayed graphically in a WWW browser.

The structure-based design of small molecule modulators of protein-ligand binding and protein-protein interaction is a key component in drug discovery. The underlying protein interactions can be regarded based on structural similarity of the involved secondary structure elements [1]. The most prominent example is the protein fold of a protein domain that is more conserved than the amino acid se...
