Abstract
Inductive content analysis is a research task in which a researcher manually reads text and identifies categories or themes that emerge from a document corpus. Inductive content analysis is usually performed as part of a formal qualitative research methodology such as Grounded Theory. Topic modeling algorithms discover the latent topics in a document corpus. There has been a general assumption, that topic modeling is a suitable algorithmic aid for inductive content analysis. In this short paper, the findings from a between-subjects experiment to evaluate the differences between topics identified by manual coders and topic modeling algorithms is discussed. The findings show that the topic modeling algorithm was only comparable to the human coders for broad topics and that topic modeling algorithms would require additional domain knowledge in order to identify more fine-grained topics. The paper also reports issues that impede the use of topic modeling within the quantitative ethnography process such as topic interpretation and topic size quantification.
