CFG Seminar: Toward an Intensional Approach to Transformation Classification

Professor Allen Renear will lead the session, "Toward an Intensional Approach to Transformation Classification."

Generating one dataset from another is a fundamental activity in data science: data curators convert datasets to different file formats, create data subsets, generate metadata, integrate data from multiple sources, and so on; data analysts generate summaries and classifications, create visualizations, and derive data about one sort of thing from data about another sort of thing. Although such transformations have been studied from a variety of perspectives, there has been little effort to develop a general classification based on intrinsic (rather than functional) characteristics, apart from computational complexity. With this paper we hope to motivate a classification of transformations based on the relationships between the intensional features of the input and output datasets, that is, their propositional and conceptual content. Intensional entities are the fundamental components of scientific reasoning and explanation and consequently deserve a uniquely central role in the analysis of information work. We believe such a classification would be a valuable contribution to the data curation curriculum. This paper is an introduction to that project.

The Conceptual Foundations Group (CFG) is an interest-based research group, centered around clarifying foundational concepts relating to information organization, data curation, and semantic technologies. Concepts related to the fundamental nature of information, descriptive metadata, digital objects and text markup are frequent topics. The group emphasizes the application of “formal methods” — that is, approaches that originated in logic, philosophy of language, analytic philosophy – to information science problem areas.
