Big data, as the name indicates, signifies a large set in the range of at least one terabyte of unstructured and structured data. The large set of data makes it difficult to handle with traditional methods. Instead, a unique set of techniques and algorithms are needed to explore trends and patterns for decision-making – called ‘Big Data Analytics’.
Big data is characterized by 3Vs, i.e., Volume, Velocity, and Variety, as described in the section below:
Volume
Volume is central to the concept of Big data. In today’s time, social media generates a huge volume of data ranging in billions of tweets, YouTube and Instagram views every day. Additionally, huge government records or data generated through new-age technology or big corporation user data must be handled using big data analytics for real-time decision-making.
Velocity
Velocity signifies the speed with which data is being generated. For instance, in the world of social media, every second and minute data is posted. Big Data architecture and analytics play a crucial role in storing the inflow of the data, making sense of it, and building on the process to adapt to the velocity of the data for decision-making.
Variety
The variety of the big data available alongside its volume and velocity makes the whole concept exciting and compelling. It includes both structured and unstructured data generated either through social media or by large corporations and includes texts, tweets, pictures & videos, voicemails, audio recordings, etc. Looking at the variety of the data available, it is quintessential to use a range of techniques to help classify data into various categories and explore it for patterns to enabling companies in decision-making.
Application of Big Data in the Social Sector
The social sector has, in recent years, started to use big data analytics to improving efficiency in operations for better targeting. For example, Big Data Analytics can be used effectively in the education sector to develop content for students based on their early learning experiences. Technology-enabled devices can be used to diagnose basic health screenings at the primary health care facility and predictive analytics can be used to predict health coverage indicators and footfalls across health facilities for assessment.
Multi-lateral and bilateral institutions have also supported global collaboration for social good. One such example is the UN Global Pulse initiative to collaborate on big data and AI for social good. The platform lists several projects ranging from operational response simulation tools for epidemics to how disaggregated data can help in providing more inclusive transport.
