Abstract: Increasing popularity of social networking sites like facebook, twitter, google+ etc. is contributing in fast proliferation of big data. Amongst social Networking sites, twitter is one of the most common source of big data where people from across the world share their views on various topics and subjects. With daily Active user count of 100-million+ users twitter is becoming a rich information source for finding trends and current happenings around the world. Twitter does provide a limited “trends” feature. To make twitter trends more interesting and informative, in this paper we propose a framework that can analyze twitter data and classify tweets on some specific subject to generate trends. We illustrate the use of framework by analyzing the tweets on “Politics” domain as a subject. In order to classify tweets we propose a tweet classification algorithm that efficiently classify the tweets.

Bigdata analysis and comparison of bigdata analytic approches

Abstract: Recent technological advancements in typical domains (e.g. internet, financial companies, health care, user generated data, supply chain systems etc.) have directed to inundate of data from these domains. Data outburst trend gave the insight meaning to the buzz word ‘Bigdata’. If we compare with traditional data, Bigdata exhibits some unique characteristics like it is commonly enormous and unstructured type of data that cannot be handled using traditional databases. Hence new system designs are required for the following processes i.e. data collection, data transmission, storage, and large-scale data processing mechanisms. The definition of Bigdata has been presented from many aspects in this paper. We analyzed Bigdata system architecture and various challenges of Bigdata. The prevalent Hadoop framework, Hive, No SQL, New SQL, MapReduce and HBase for addressing the biggest challenge of Bigdata i.e Data Analytic has also been analyzed and compared.

Outcome-Based Quality Assessment Framework for Higher Education.

Abstract: This research paper proposes a quality framework for higher education that evaluates the performance of institutions on the basis of performance of outgoing students. Literature was surveyed to evaluate existing quality frameworks and develop a framework that provides insights on an unexplored dimension of quality. In order to implement and test the framework, cloud-based big data technology, BigQuery, was used with R to perform analytics. It was found that how the students fair after passing out of a course is the outcome of educational process. This aspect can also be used as a quality metric for performance evaluation and management of educational organizations. However, it has not been taken into account in existing research. The lack of an integrated data collection system and rich datasets for educational intelligence applications, are some of the limitations that plague this area of research. Educational organizations are responsible for the performance of their students even after they complete their course. The inclusion of this dimension to quality assessment shall allow evaluation of educational institutions on these grounds. Assurance of this quality dimension shall boost enrolments in postgraduate and research degrees. Moreover, educational institutions will be motivated to groom students for placements or higher studies.

E-GENMR: Enhanced Generalized Query Processing using Double Hashing Technique through MapReduce in Cloud Database Management System

Abstract: Big Data, Cloud computing and Data Science is the booming future of IT industries. The common thing among all the new techniques is that they deal with not just Data but Big Data. Users store various kinds of data on cloud repositories. Cloud Database Management System deals with these large sets of data. Cloud Database service provider deals with many obstacles while providing various service. Amongst all the challenges processing of large amount of data, interoperability and security are the major concerns that are explained in this study. Enhanced Generalized Query Processing through MapReduce (E-GENMR) is a prototype model that provides solution for these problems. Firstly, traditional approaches are not suitable for processing such gigantic amount of data as they are not able to handle such amount of data. Various solutions have been developed such as Hadoop, MapReduce Programming codes, HIVE, PIG etc. but these technologies don't provide solution for these problems at the same time and moreover users are not compatible with these latest technologies like MapReduce codes. E-GENMR provides interoperability as it takes queries written in various RDBMS forms like SQL Server, ORACLE, DB2, MYSQL and convert into MapReduce codes as they are considered to be the efficient way for processing large data. Secondly, Client's data is stored in encrypted form and processing is done on this data hence it ensures the security aspect. Indexing plays a very important role in processing queries, in E-GENMR indexing is implemented using closed double hashing technique. We compared various query processing time of E-GENMR for encrypted data and unencrypted data. A comparison of various queries has been done to evaluate the performance of E-GENMR with latest techniques like Hadoopdb, SQLMR, HIVE and PIG and it has been concluded that E-GENMR shows better performance.

Exploiting Data Reduction Principles in Cloud-Based Data Management for Cryo-Image Data

Abstract: Cloud computing is a cost-effective way for start-up life sciences laboratories to store and manage their data. However, in many instances the data stored over the cloud could be redundant which makes cloud-based data management inefficient and costly because one has to pay for every byte of data stored over the cloud. Here, we tested efficient management of data generated by an electron cryo microscopy (cryoEM) lab on a cloud-based environment. The test data was obtained from cryoEM repository EMPIAR. All the images were subjected to an in-house parallelized version of principal component analysis. An efficient cloud-based MapReduce modality was used for parallelization. We showed that large data in order of terabytes could be efficiently reduced to its minimal essential self in a cost-effective scalable manner. Furthermore, on-spot instance on Amazon EC2 was shown to reduce costs by a margin of about 27 percent. This approach could be scaled to data of any large volume and type.
