A formal account linked ENA's network pictures to its high-dimensional mathematics

Dale Bowman, Zachari Swiecki, Zhiqiang Cai, Yeyu Wang, Brendan Eagan, Jeff Linderoth, David Williamson Shaffer

2nd International Conference on Quantitative Ethnography (ICQE 2020)

The formal transformations that connect coded observations, accumulated unit networks, metric space, projection, and interpretable node placement in ENA. The derivation supports two core affordances: comparing the content of networks with summary statistics and interpreting those comparisons through network visualizations aligned with the model. Mathematical consistency does not guarantee construct validity, representative sampling, reliable coding, appropriate dependence assumptions, or a correct substantive interpretation.

Segmentation sensitivity was modest overall but substantial for some interview networks

Szilvia Zörgő, Zachari Swiecki, A. R. Ruis

2nd International Conference on Quantitative Ethnography (ICQE 2020)

How alternative segmentation decisions affect population-level and individual ENA features in continuous interview narratives. Segmentation changes did not necessarily alter overall model features, yet their effects on particular individual networks could be substantial. The magnitude and direction of sensitivity depend on the narrative structure, code distribution, window, and segmentation alternatives used in this dataset.

Human–NLP collaboration made three dimensions of qualitative trustworthiness inspectable

Ha Nguyen, June Ahn, Ashlee Belgrave, Jiwon Lee, Lora Cawelti, Ha Eun Kim, Yenda Prado, Rossella Santagata, Adriana Villavicencio

2nd International Conference on Quantitative Ethnography (ICQE 2020)

How natural language processing combined with researcher interpretation can strengthen credibility, dependability, and confirmability in qualitative analysis. The case demonstrates practical affordances for efficient analysis while keeping human examination central to the claims and to the trustworthiness audit. A successful illustration does not make NLP output inherently credible, transferable, or unbiased; trustworthiness still depends on data quality, researcher reflexivity, validation, and transparent disagreement handling.

Topic modeling helped discover candidate codes but could not replace human interpretation

Zhiqiang Cai, Amanda Siebert-Evenstone, Brendan Eagan, David Williamson Shaffer

2nd International Conference on Quantitative Ethnography (ICQE 2020)

Whether unsupervised topic models can support the discovery of qualitative codes in large textual corpora. Topics often mixed several human codes, and words linked to one human code could appear across multiple topics; concise topic-word lists were more useful as discovery aids than direct replacements for codes. Alignment with one coded corpus does not establish that a topic model will recover valid constructs in another domain, language, or preprocessing pipeline.

A field scan mapped opportunities and recurring trustworthiness challenges in QE

Rogers Kaliisa, Kamila Misiejuk, Golnaz Arastoopour Irgens, Morten Misfeldt

2nd International Conference on Quantitative Ethnography (ICQE 2020)

Which practices, opportunities, and unresolved challenges characterized the emerging field of quantitative ethnography. Grounded analysis and attention to code validity were common, while interpretability, methodological consistency, and clearer reporting remained visible field-level challenges. A scoping review describes the accessible literature and its reporting practices; it does not prove that one workflow is universally superior or that omitted studies followed the same pattern.
