Abstract: The increasing digital transformation of society in recent decades has resulted in a number of new data sources for the social, behavioural, and economic sciences. Among many others, they include unstructured data, which are characterised by not being available in a fixed data format and are therefore not easy to process for data analysis (e.g., Facebook posts, Instagram images, YouTube videos, Twitter messages). The use of unstructured data is linked to specific challenges, which arise precisely because the data are not typically collected as part of a controlled, scientific study but are often created in people’s natural environments. Building on the results of an expert workshop, we describe the specific challenges of generating and using unstructured data and formulate recommendations for their use. Our recommendations are based on the total error framework and take into account data generation (definition of the units of analysis, coverage and sampling error, non-response, and missing data error), post-collection processing (specification error, validity, measurement error, and error in terms of content), and, lastly, data analysis (record linkage and processing errors, modelling errors, analytical errors). Finally, we discuss open questions and challenges to research using unstructured data.
