Abstract
The benefits and also the challenges of big data analytics can be addressed in innovative ways. It is known that analytical focus is important. Considering just as an analogy for our analytics, how a microscope or a telescope bring about observation and measurement at very fine scales and at very gross scales, we can take that analogy as being associated with the resolution scale of our analysis. Another challenge is the bias in big data. But we may calibrate our analytical process with a big data framework or infrastructure. A further challenge of an ethical nature is how respresentativity replaces the individual. So, we want to rehabilitate the individual. Important opportunities arise from contextualization that can be associated with the resolution scale of our analytics, and it can also be supported by full account taken of appropriate contexts. The innovation that stems from the different facets of our analytical procedures can be of great benefit. Here, we seek to discuss many such themes that are always in the context of interesting and important case studies. The main case studies for us here include the following: analytics of mental health and associated well-being; social media analytics based on Twitter; questionnaire and survey analytics with many respondents.
