With the growth of different search engines, it becomes difficult for an user to search particular information effectively. If a search engine could provide domain specific information such as that confines only to a particular topicality, it is referred to as domain specific engine. Applying the ranking model trained for broad-based search to a domain specific search does not achieve good perf...

In this paper, we describe our methods for ImageCLEF 2013 Personal Photo Retrieval Task. We devote our attention to making our system efficient in retrieving documents which have the similar topic with few query data. We train a ranking function using rankSVM. We extract Fisher Vectors (FVs) from several local descriptors as visual features, and use Bag-of-Words (BoW) as metadata features. The ...

The significant increase in the volume of fake (spam) messages has led to an urgent need develop and implement a robust anti-spam method. Several current systems depend mainly on word order message determining spam message, which results system's inability predict correct type when changes. In this paper, new framework is proposed for filtering that does not word's position called Trigonometric...

This paper proposes the use of a goal programming model for objective ranking universities. methodology has been successfully used in other areas to analyze performance firms by focusing on two opposite approaches: (a) one favouring those variables that are aligned with central tendency majority measurement performance, and (b) an alternative favours different, singular, or independent variable...
