2. Technology
3. Methods
4. Impact - 4What does "information" as a theme of Big Data represent? (1)1. The digitisation and datafication revolution that fuels Big Data
- 5What does "technology" as a theme of Big Data represent? (4)The medium that facilitates the:
1. Collection
2. Processing
3. Transmission
4. Storage
of Big Data - 6What does "methods" as a theme of Big Data represent?1. Techniques used to process Big Data
2. The interdisciplinary knowledge required to understand and apply Big Data (e.g. STEM + Humanities) - 7What does "impact" as a theme of Big Data represent? (2)1. The pervasive omnipresence of Big Data in our lives
2. The degree which Big Data affects our lives - 8Why does Big Data require technology to be interpreted? (2)1. High Volume, Velocity and Variety makes it difficult for humans to analyse effectively
2. Technology provides analytical methods to interpret it and gain Value - 9What are the "Four V's" of Big Data?1. Volume = Amount / Scale of data
2. Velocity = Speed of data generation / processing
3. Variety = Types of data (e.g. Structured, Unstructured, Semi-Structured)
4. Veracity = Accuracy and reliability of the data - 10Name and explain three V's besides the Four V's that could help describe Big DataVariability: Inconsistencies / Disparencies
Validity: Accuracy / Appropriateness
Vulnerability: Security concerns of data or its use
Volatility: How long before data becomes outdated
Visualisation: Representing data visually helps humans interpret it
Value: What purpose / insights of data - 11What are the six provocations of Big Data according to Boyd and Crawford?1. Changes the definition of knowledge
2. Claims to objectivity and accuracy are misleading
3. Bigger data ≠ Better Data
4. No context = No meaning
5. Accessible data ≠ Ethical data
6. Power of Big Data widens the Digital Divide - 12How can Big Data challenge our concept of what knowledge is? (2)1. Big Data cannot be interpreted w/o technology
2. Radical shift in how we think about / do research - 13Why can claims to objectivity and accuracy in Big Data be misleading? (3)1. Bias in how the data is collected
2. Bias on the forms/types of data collected
3. Bias in how the data is presented - 14Why does bigger data not always equal better data? (2)1. Volume is so large that little things can go unnoticed
2. Smaller data sets and outliers can tell us things big data may overlook - 15Why does big data require context for it to have Value? (2)1. Volume of data mandates explanation to understand connections between the data
2. Context grants insight into how the Value of the data can be applied - 16Why is accessible data not always ethical to use? Give an example. (2)1. Researchers should be accountable towards their research subjects (e.g. informed consent)
2. Examples: Gleaning data off of public social media profiles, using identifying details gained from public records etc. - 17What is the Digital Divide and how can Big Data worsen it? (2)1. Digital Divide: Advantages / Necessity of technology puts those without access to it at a disadvantage
2. Big Data holds so much power that those without it can be at a disadvantage - 18What are two concerns / issues that arise from Big Data? (2)1. Privacy and increased surveillance
2. Ethical use of data
3. Worsens the Digital Divide
