Trend and applications of Big Data and IoT techniques

As people say "Data is the new oil," Big data is expected to make a large impact on our society and economics by mining hidden knowledge and rules from the data. In particular, the structure of the real world data is changing from traditional relational data model to more generalized graph data model, as the web and social media are getting popular in the world. One of the most important technical challenges here is to efficiently analyze large graph data that express various types of relationship between people, items, and places. In this talk, we overview the trend of Big Data and IoT and then explain our research on distributed query optimization on cloud environment and efficient graph mining algorithms. Finally, we introduce some of our interesting applications of Big Data: 1) social network analysis by employing graph mining algorithms, 2) business data analysis by exploratory data analysis techniques, and 3) Smart route recommendation system empowered by IoT.
