Title: Big Data Issues and Challenges
Abstract:  Nowadays, the immense use of computers in daily life leads to the creation of big data. Big data is a collection of vast data stored together and its term is used to describe the exponential growth of structured and unstructured data. Big data has three characteristics: volume, velocity, and variety. Such data can be found in many places, such as personal computers, universities archives, news archives, and textual documents. The most tremendous growth of these data can be found in social media. Social media technologies provide many different forms of presenting information, such as in magazines, Internet forums, weblogs, social blogs, micro-blogging, wikis, social networks, podcasts, photographs or pictures, videos, rating, and social bookmarking. Several attempts have been conducted to deal with massive data in social media, such as news extraction, aggregation, clustering, news topic detection and tracking, and social network analysis. Additional technologies, such as massive parallel-processing databases, distributed file systems, and cloud computing technologies, have been introduced to manage big data. However, these methods face the challenges of extracting, transformation, integrating, sorting, and manipulating data. The visualization of social media data is not feasible. However, realizing and understanding the events that occur in society is important to users. Therefore, in this talk will summarize the issues and challenges of big data.
