several semantic image search schemes have been recently proposed to retrieve images from the web. however, the query context is regularly ignored in these techniques and hence, many of the returned images are not adequately relevant. in this paper, we make use of context to further confine the outcome of the semantic search engines. for this purpose, we propose a hybrid search engine which uti...

This research explores a Natural Language Processing technique utilized for the automatic reduction of melodies: the Probabilistic Context-Free Grammar (PCFG). Automatic melodic reduction was previously explored by means of a probabilistic grammar [11] [1]. However, each of these methods used unsupervised learning to estimate the probabilities for the grammar rules, and thus a corpusbased evalu...

Context aware e-learning system helps to provide elearning contents which are customized according to the learner’s context. For generating context aware contents many adaptation parameters have to be considered. Customized learning path is one such adaptation parameter. In the existing elearning systems, learning paths is generated using several approaches. But in order to generate context awa...

the purpose of present study is to evaluate the role of teaching entrepreneurship on the employment of iranian higher education graduates in today`s changing world. the delphi method is used and a sample of 46 entrepreneurship specialists is questioned about the subject. once the data are collected, they are analyzed using χ2-square freedman test and kendal correlation. final results reveal tha...

The simultaneously phonological and syntactic grammar of second position clitics is an instance of the broader problem of applying constraints across multiple levels of linguistic analysis. Syntax frameworks extended with simple tree transductions can make efficient use of these necessary additional forms of structure. An analysis of Sahidic Coptic second position clitics in a context-free gram...

Context-aware computing has to deal with a huge amount of context data. Taking into account the quality of these data becomes a corner stone of an efficient context management solution. Information on the quality of context helps taking appropriate decisions and allows to identify uncertain context information saving processing time for deriving a pertinent description of the observed phenomeno...
