• Publication Date and Conference: UIST ’22, October 29-November 2, 2022, Bend, OR, USA

Research Background and Issues

• Research Issues:

  • Traditional qualitative research methods (e.g., thematic analysis, grounded theory analysis) rely on scholars gradually reading texts for coding and iterative categorization, which is time-consuming and difficult to scale to large datasets.
  • Statistical topic modeling enables rapid analysis of large-scale text data but overly relies on statistical patterns, lacking deep semantic understanding and alignment with research questions, potentially leading to bias.
  • Studies show that qualitative researchers are skeptical of algorithm usage, fearing that algorithms might replace human insight or introduce bias.

• Research Motivation:

  • To provide a human-centered design that supports efficient and effective analysis of qualitative data through interactive machine learning and visualization tools, while minimizing disruption to existing human workflows.

• Related Work:

  • Current tools like MaxQDA and NVivo offer basic statistical functionalities but lack support for large-scale data sampling and interactive model optimization.
  • Previous studies, such as Termite and TOME, have designed visualization-based topic modeling methods but have not adequately addressed the integration of human perception and algorithms in qualitative research.

Solution

• Methods and Solution:

  1. Introduce Scholastic, a visual analysis tool specifically designed to support qualitative and interpretive text data analysis, combining machine learning with human input.
  2. System implementation includes interactive document and word clustering algorithms, using human-created codes and classifications as constraints.
  3. Provide familiar user interface designs and visualization patterns, such as Geographical Treemaps and Indented Trees, to reduce usage barriers.

• Innovations:

  • Incorporate machine learning to assist document clustering while granting users the flexibility to define and optimize codes and classifications.
  • Utilize Geographical Treemaps to avoid biases from traditional algorithm-generated content summaries, encouraging users to create their own cognitive models during exploration.
  • The dual-layer network design (text layer and metadata layer) allows scholars to iteratively model without disrupting traditional qualitative analysis workflows.

• Implementation Steps and Techniques:

  1. Data coding phase: Researchers highlight text passages in documents and apply codes and keywords.
  2. Classification and modeling phase: Researchers integrate codes using classification tools, updating the model to generate incremental human-AI interactive clustering.
  3. Visualization presentation: Understand data distribution and clustering results through dynamic interactive diagrams and hierarchical tree structures.

Research Outcomes

• Specific Outcomes:

  1. Developed the Scholastic system, providing three core functional modules: Document Map (random sampling and broad exploration), Document Reader (coding and memo writing), and Code Reviewer (classification and deep search).
  2. User testing demonstrated Scholastic's ability to spark curiosity among human analysts and support flexible document sampling strategies.
  3. Keyword selection functionality and transitional markers enable real-time updates during data modeling, enhancing machine learning responsiveness to human input.

• Advantages Over Existing Solutions:

  • Supports large-scale text data analysis while maintaining qualitative researchers' control over their studies.
  • Breaks the one-way constraint between existing qualitative tools and statistical methods, offering an interactive and flexible analysis approach.
  • Reduces the learning curve significantly through familiar interaction patterns.

• Experiment and Evaluation Results:

  • In experiments with two experienced qualitative researchers, Scholastic was rated as intuitive, user-friendly, and engaging.
  • The Document Map module excelled in inspiring exploratory data sampling, with participants spontaneously naming and memorizing clustered regions through visual features and dynamic interactions.
  • Task sequence experiments confirmed that the tool design aligns with qualitative researchers' natural workflows without disrupting existing practices.

• Limitations and Future Directions:

  • Current functionalities do not cover all qualitative research method requirements (e.g., support for more complex multi-code functionalities).
  • The system requires further expansion for longitudinal evaluations of efficiency, effectiveness, and user trust in long-term studies.
  • Future research will explore the impact of visual features on learning and memory and develop scalable frameworks to accommodate various disciplines or analysis needs.
