This paper presents recent results using statistics generated by a MMl-supervised vector quantizer as a measure of audio similarity. Such a measure has proved successful for talker identification, and the extension from speech to general audio, such as music, is straightforward. A classifier that distinguishes speech from music and non-vocal sounds is presented, as well as experimental results ...

This paper presents an application of PageRank, a random-walk model originally devised for ranking Web search results, to ranking WordNet synsets in terms of how strongly they possess a given semantic property. The semantic properties we use for exemplifying the approach are positivity and negativity, two properties of central importance in sentiment analysis. The idea derives from the observat...

This paper presents an Extended WordNet based word sense disambiguation system using a major modification to the Lesk algorithm. The algorithm tries to disambiguate nouns, verbs and adjectives. The algorithm relies on the POS-sense tagged synset glosses provided by the Extended WordNet. The basic unit of disambiguation of our algorithm is the entire sentence under consideration. It takes a glob...

Many corpus-based machine translation systems require parallel corpora. In this paper, we present a word-for-word glossing algorithm that requires only a source language corpus. To gloss a word, we first identify its similar words that occurred in the same context in a large corpus. We then determine the gloss by maximizing the similarity between the set of contextually similar words and the di...

This paper continues the study of the Gregory-Laflamme instability of black strings, or more precisely of the order of the transition, being either first or second order, and the critical dimension which separates the two cases. First, we describe a novel method based on the Landau-Ginzburg perspective for the thermodynamics that somewhat improves the existing techniques. Second, we generalize ...

Commonsense reasoning requires extensive knowledge. In order to be useful for practical artiicial intelligence problems, a knowledge base needs to have millions of concepts and relations. The nature of knowledge is such that even solutions to relatively small, narrow artiicial intelligence problems require a great deal of knowledge. Unfortunately, knowledge cannot be modularized or partitioned....

The popularity of information retrieval has led users to a new problem: nding which text databases (out of thousands of candidate choices) are the most relevant to a user. Answering a given query with a list of relevant databases is the text database discovery problem. The rst part of this paper presents a practical method for attacking this problem based on estimating the result size of a quer...

We propose a novel subband-based S-curve transformation for increasing the perceived contrast of images, and use it to explore the relation between perceived gloss and perceived contrast of natural textures. The proposed transformation makes minimal assumptions on lighting conditions and does not require prior knowledge of surface geometry. Through a series of subjective experiments with both c...

BACKGROUND The purpose of this study was to evaluate orthodontic debonding methods by comparing the surface roughness and enamel morphology of teeth after applying two different debonding methods and three different polishing techniques. METHODS Forty eight human maxillary premolars, extracted for orthodontic reasons, were randomly divided into three groups. Brackets were bonded to teeth with...
