- Conference PaperMachine Learning and Grounded Theory Method: Convergence, Divergence, and Combination(Proceedings of the 2016 ACM International Conference on Supporting Group Work, 2016) Muller, Michael; Guha, Shion; Baumer, Eric P.S.; Mimno, David; Shami, N. SadatGrounded Theory Method (GTM) and Machine Learning (ML) are often considered to be quite different. In this note, we explore unexpected convergences between these methods. We propose new research directions that can further clarify the relationships between these methods, and that can use those relationships to strengthen our ability to describe our phenomena and develop stronger hybrid theories.
- Conference PaperVeterans, PTSD and Social Media: Towards Identifying Trauma Text Categories Using Grounded Theory(Companion Proceedings of the 2020 ACM International Conference on Supporting Group Work, 2020) Coelho, Joseph; Hooyer, Katinka; Olsen, Danielle; Annapureddy, Priyanka; Johnson, Nadiyah; Madiraju, Praveen; Franco, Zeno; Flower, Mark; Ahamed, Sheikh IqbalText classification using machine learning can be applied in various contexts such as in classifying research papers, identifying relevant news stories, and detecting fake reviews. Training an algorithm to perform such tasks generally requires a dataset with predefined labels. Valid labels for texts in a given domain can be predefined by domain experts. However, when it comes to free-form text from messaging applications and social networking sites it is difficult to predict what labels may be extracted from the text. Grounded theory provides a method by which concepts that emerge from data can be expressed as categories and properties. These categories and properties can then be arranged in a hierarchical class label structure that can be used to build a dataset for training models. This study focuses on text related to veterans with post traumatic stress disorder and identifies a hierarchical class label structure, with the future goal of applying this to prevent crisis situations.
