The idea is that they are media platforms with social components and public communication channels. Social media are primarily Internetbased tools for sharing and discussing information among human beings. Data mining (the analysis step of the “Knowledge Discovery in Databases” process, or KDD), is the process that attempts to discover patterns in large data sets. The overall goal of the data mining process is to extract information from a data set and transform it into an understandable structure for further use. It involves database and data management aspects, data preprocessing, model and inference considerations, interestingness metrics, complexity considerations, postprocessing of discovered structures, visualization, and online updating. Link prediction in Facebook and Twitter can be done at a familiar class of graph generation model, where the nodes are united with locations in a latent metric space and connections are more likely between closer nodes. In this paper, Gephi tool is used to predict the link of Facebook.Item LINK PREDICTION MODEL FOR PAGE RANKING OF BLOGS(International Journal on Computer Science and Engineering, 2012-11) S, Geetha; K, SathiyakumariSocial Network Analysis is mapping and measuring of relationships and flows of information between people, organizations, computers, or other information or knowledge processing entities. Social media systems such as blogs, LinkedIn, you tube are allows users to share content media, etc. Blog is a social network notepad service with consider on user interactions. In this paper study the link prediction and page ranking using MozRank algorithm using blog websites. It finds out how all the websites on the internet link to each other with the largest Link Intelligence database. As link data is also a component of search engine ranking, understanding the link profile of Search Engine positioning. Here the MozRank algorithm is using backlinks from blog websites and linking websites quality. Good websites with many backlinks which linking the corresponding WebPage give highly value of MozRank. MozRank can be improved a web page's by getting lots of links from semi-popular pages or a few links from very popular pages. The algorithm for page ranking must work differently and MozRank is more comprehensive and accurate than Goggle’s page rank. Another tool is Open Site Explorer that is ability to compare five URL's against each other. Open Site Explorer’s Compare Link Metrics option is how one measures page level metrics, the other domain. This result can help to generate a chart form for the comparative URLs. A comparison chart of the important metrics for these pages is shown which makes it very clear and easy to compare the data between the five URL's.Item BACKLINK ANALYSIS USING MOZRANK ALGORITHM OF BLOGS(The International Journal of Computer Science & Applications, 2012-11) S, Geetha; K, SathiyakumariSocial networking has become very popular during the past few years, but it can still very difficult to understand for someone new to social networking. Social networking is based on a certain structure that allow people to both express their individuality and meet people with similar interests. This structure includes having profiles, friends, blog posts, widgets, and usually something unique to that particular social networking website such as the ability to ‘poke’ people on facebook or hi5. Blogs is another feature of some social networks is the ability to create own blog entries. While not as feature rich as blog hosts like wordpress or blogger, blogging through a social network is perfect for keeping people informed on own information. This paper represents a web page ranking algorithm using mozrank algorithm for blog searching and the ranking web sites. In this algorithm can be using online tool. The majesticseo and open site explorer using blog page ranking with the mozrank algorithm.

Text document clustering is one of the emerging and most needed clustering techniques used to cluster documents with regard to similarity among documents. It is used widely in digital library management system in the modern context. Document clustering is widely applicable in areas such as search engines, web mining, information retrieval, and topological analysis. There are several clustering approaches available in the literature to cluster the document. But most of the existing clustering techniques suffer from a wide range of limitations. The existing clustering approaches face the issues like practical applicability, very less accuracy, more classification time etc. Thus a novel approach is needed for providing significant accuracy with less classification time. In recent times, inclusion of fuzzy logic in clustering provides better clustering results. One of the widely used fuzzy logic based clustering is Fuzzy C-Means (FCM) Clustering. In order to further improve the performance of clustering, this thesis uses Modified Fuzzy C-Means (MFCM) Clustering. The documents are ranked using Term Frequency–Inverse Document Frequency (TF–IDF) technique. From the experimental results, it can be observed that the proposed technique results in better clustering when compared to the FCM clustering technique.
