On Methods to Analyse and Visualize Data

  1. 1. CODING DÜRER’17 Nuria Rodríguez Ortega nro@uma.es University of Málaga On Methods to Analyse and Visualize Data (A general framework)

  3. 3. CODING DÜRER’17 Questions WHERE CAN WE FIND DATA? HOW TO MANAGE DATA? HOW TO INTERPRET DATA?
  4. 4. WHERE TO FIND DATA? CODING DÜRER’17 WHERE TO FIND DATA? Questions Already existing data collections and databases Cultural domains without structured datasets available = aggregation of structured data and metada is needed User-generated, social-produced data on Internet
  5. 5. CODING DÜRER’17 HOW TO MANAGE DATA? Data representation HOW TO MANAGE DATA? Skills needed 1. Data representation / Modelling cultural phenomena 1.1. Questions to bear in mind/ Decisions What are the boundaries? What are the objects? What are the attributes? How do objects interrelate among them? 1.2. Transforming analog objects and concepts into discrete data Object’s decomposition into attributes and variables

Data representation Change of perspective: from the object as entity to a set of correlated attributes Baroque pictorial production represented as semantic maps configured by clusters of commun attributes
  7. 7. CODING DÜRER’17 How to manage data? Data representation HOW TO MANAGE DATA? Skills needed 1. Data representation / modelling cultural phenomena 1.3. Bias & Transparency: potential and/or real biases, complete datasets and algorithms should always be made available 1.4. Understanding of data as cultural construct New questions & new decisions: - How to express cultural complexity in terms of structured data? - How to build more flexible structured datasets? - How to categorize uncertain and ambiguous concepts? - How to express missing data?
