Concepts embody the knowledge to facilitate our cognitive processes of learning. Mapping short texts to a large set of open domain concepts has gained many successful applications. In this paper, we unify the existing conceptualization methods from a Bayesian perspective, and discuss the three modeling approaches: descriptive, generative, and discriminative models. Motivated by the discussion o...

The Semantic based annotation of an image is very important and a difficult task in content-based image retrieval (CBIR). The low-level features of the images are described using color and the texture features and the proposed model is used for semantic annotation of images. Also the textual annotations or the tags with multimedia content are the most effective approaches to organize and to sup...

This paper reviews trends in research related to Korean pharmacopuncture therapy. Specifically, basic and clinical research in pharmacopuncture within the last decade is summarized by introducing categorical variables for classification. These variables are also analyzed for association. This literature review is based on articles published from February 1997 to December 2008 in a Korean journa...

We sketch the ideas behind the use of chromatic numbers in establishing descriptive set-theoretic dichotomy theorems.

We continue with the task of obtaining a unifying view of process semantics by considering in this case the logical characterization of the semantics. We start by considering the classic linear timebranching time spectrum developed by R.J. van Glabbeek. He provided a logical characterization of most of the semantics in his spectrum but, without following a unique pattern. In this paper, we pres...

This paper studies the descriptional complexity of multi-parallel grammars with respect to the number of nonterminals and selectors, and the length of these selectors. As a result, it proves that every recursively enumerable language is generated by a multi-parallel grammar with no more than seven nonterminals and four selectors of length five.

This paper presents a general framework for analyzing heuristics for constraint solving, including backtracking and arc consistency algorithms. It will emphasize heuristics for variable selection during search, since this is where major differences are found. In earlier work two basic approaches to this problem were developed. The first was a general theoretical framework for different types of...

Protection of privacy in databases has become of increasing importance. While a number of techniques have been proposed to query databases while preserving privacy of individual records in the database, very little is done to define a measure on how much privacy is lost after statistical releases. We suggest a definition based on information theory. Intuitively, the privacy loss is proportional...

abstract background: well-being is a subjective concept and means different things to various people. most of the research investigating the experience has concentrated on its problematic and pathological aspects. the aim of this research was to enhance the understanding of the contextual meaning of well-being based on personal life experiences of the participants. this will be of help to exper...
