Text Mining for Processing Interview Data in Computational Social Science
This study provides a practical guide for social science researchers on using text analysis tools for interview data, particularly for exploratory phases, addressing the challenge of efficiently processing qualitative data for quantitative analysis.
This paper explores the application of commercial text analysis technology to interview data in computational social science, demonstrating its utility for topical clustering and terminological enrichment, which facilitates hypothesis generation and testing while reducing analyst effort. It highlights that while lexical statistics quantify many variables, some valuable features remain difficult to automate reliably.
We use commercially available text analysis technology to process interview text data from a computational social science study. We find that topical clustering and terminological enrichment provide for convenient exploration and quantification of the responses. This makes it possible to generate and test hypotheses and to compare textual and non-textual variables, and saves analyst effort. We encourage studies in social science to use text analysis, especially for exploratory open-ended studies. We discuss how replicability requirements are met by text analysis technology. We note that the most recent learning models are not designed with transparency in mind, and that research requires a model to be editable and its decisions to be explainable. The tools available today, such as the one used in the present study, are not built for processing interview texts. While many of the variables under consideration are quantifiable using lexical statistics, we find that some interesting and potentially valuable features are difficult or impossible to automatise reliably at present. We note that there are some potentially interesting applications for traditional natural language processing mechanisms such as named entity recognition and anaphora resolution in this application area. We conclude with a suggestion for language technologists to investigate the challenge of processing interview data comprehensively, especially the interplay between question and response, and we encourage social science researchers not to hesitate to use text analysis tools, especially for the exploratory phase of processing interview data.?
