In recent years, many studies on extracting new bilingual lexicons from non-parallel (comparable) corpora have been proposed. Nearly all apply an existing small dictionary or other resource to make an initial list named seed dictionary. In this paper we discuss on using different types of dictionaries and their combinations as the initial starting list to produce a bilingual Persian-Italian lexicon from a comparable corpus. Our experiments applied state of the art techniques on four different seed dictionaries; an existing dictionary and three dictionaries created with pivot-based schema considering three different languages as pivot. We have used English, Arabic and French as pivot languages to extract these three pivot based dictionaries. An interesting challenge in our approach is proposing a method to combine different dictionaries together producing a better and more accurate lexicon. In order to combine seed dictionaries we proposed two novel combination models and examine the effect of them on comparable corpora which are collected from News Agencies. The experimental results exploited by our implementation show the efficiency of our proposed combinations.Keywords

This paper review on the cloud computing technology. The virtualization is major concern in the clouds. The virtualization using different hypervisors such as Xen, KVM and Danali are described. The overview on the current cloud providers and ongoing open source research activities are described. The analysis of cost of investment and savings due to virtualization, makes it very important for many business policies. The saving and its relation with clouds is done using apcmedia tool. The positive results are very interesting and motivating to find out relation between cloud computing and green computing. The results are fine indication that, the cloud computing moving towards the green computing.
