TY - Generic T1 - Machine Learning and Rule-Based Automated Coding of Qualitative Data T2 - American Society for Information Science and Technology (ASIST) Annual Conference Y1 - 2010 A1 - Kevin Crowston A1 - Xiaozhong Liu A1 - Allen, Eileen E. A1 - Heckman, Robert KW - FLOSS KW - NLP AB - Researchers often employ qualitative research approaches but large volumes of textual data pose considerable challenges to manual coding. In this research, we explore how to implement fully or semi-automatic coding on textual data (specifically, electronic messages) by leveraging Natural Language Processing (NLP). In particular, we compare the performance of human-developed NLP rules to those inferred by machine learning algorithms. The experimental results suggest that NLP with machine learning can be an effective way to assist researchers in coding qualitative data.
