DIR is more complex than the centralized information retrieval IR . It requires addressing two significant additional problems that are the resource selection and the results merging. Many techniques for addressing the two problems have been published in the literature. However they still have a negative impact on retrieving quality and response time. This paper aims to improve the DIR efficiency through using a meta heuristic algorithm and improving the result quality through a query expansion. The algorithm has been strengthened using the nearest neighbor graph in order to improve the search performance.","PeriodicalId":115908,"journal":{"name":"Journal of Kufa for Mathematics and Computer","volume":"33 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-12-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123878208","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In addition students are suffering from inequity related to rural-urban differences and in sufficient resource allocation for the education system especially outside the cities. Three methods of principal component analysis Jolliffe method, Screen diagram method and Bartlett method have been used in this study. The method has been chosen as the best method. According to the methods the most important of e-learning are improves student’s performance, decreases the need of having special tutors, provides sufficient facilitation for disabled students, importance for external students and reduces the rural-urban division gap. Based on what have been mentioned and for the purpose of reforming and enhancing the education system, Information Technology (IT) has been suggested.

First, extract the features by color moment and (Hue, Saturation, Value HSV color space as a color feature, and then get the co-occurrence matrix as well as Discrete Wavelet Transform DWT for a texture feature. Chain codes algorithm, specifically chain code histogram, is then applied to obtain the codes of the shape feature. Second, collect all these features and store it in the database, where each record represents one image of the dataset. Similarity process is executed to find the images that are more similar to the query image, retrieved images ranked.
