“Big data is high-volume, high-velocity and high-variety information assets that demand cost-effective, innovative forms of information processing for enhanced insight and decision making.” – Gartner (Ching, 2015)

IBM describes these new demands across four dimensions: Volume, Velocity, Variety and Veracity. (ibm, 2015)

Big Data PhD Research topics which I found :

1) Improving Data analytic techniques- Gather all datas,filter them out on certain constraints and use them to take confident decisions.

2) Natural Language Processing methods - Use NL-processing techniques on Big Datas to find out the current sentimental trend and it can be used on business,politics,finance ...etc

3) BigData tools and deployment platforms -Conventional tools are inefficient to handle Bigdata, Lots of research is needed in these fields.

4) Better datamining techniques-Data mining is the method to grab datas from various platforms.Improved distributed crawling techniques and algorithms are need for scrape datas from multiple platforms.

5) Algorithms for Data visualization-In order to visualize the required information from a pool of random datas, powerful algorithms are crucial for accurate result.

Anybody is willing to share about what is other hottest research topic related to BIG DATA/PhD academic field in 2016? Thanks.
