Special issue: Shape Representation and Similarity for Image Databases

The recent increased usage of image and multimedia databases has motivated research in developing and applying shape similarity measures. Enhancing color and texture based similarity measures by the use of shape information is unavoidable, since only in very restricted domains can color and texture information alone lead to systems which perform reasonably. Shape is an important part of the sem...

New distance and similarity measures for hesitant fuzzy soft sets

The hesitant fuzzy soft set (HFSS), as a combination of hesitant fuzzy and soft sets, is regarded as a useful tool for dealing with the uncertainty and ambiguity of real-world problems. In HFSSs, each element is defined in terms of several parameters with arbitrary membership degrees. In addition, distance and similarity measures are considered as the important tools in different areas such as ...

The main aim of this study is to develop part-of-speech tagger for Afaan Oromo language. After reviewing literatures on Afaan Oromo grammars and identifying tagset and word categories, the study adopted Hidden Markov Model (HMM) approach and has implemented unigram and bigram models of Viterbi algorithm. Unigram model is used to understand word ambiguity in the language, while bigram model is u...
