Managing unmanageable loads of evidence: Are living reviews the solution?

Artificial Intelligence (AI) has made significant advancements in the field of qualitative data analysis (CAQDAS). While AI, particularly machine learning, is often associated with quantitative data analysis, it is increasingly being utilized in the qualitative domain as well. In fact, the use of AI in CAQDAS can be traced back to the late 1980s when the first qualitative software programs emerged.

One of the pioneering CAQDAS packages was Qualrus, developed by Prof Ed Brent in 2002. Unlike its predecessors, Qualrus went beyond simple word/phrases searches and auto-coding. It integrated case-based reasoning, natural language understanding, machine learning, and semantic networks to suggest codes based on patterns in qualitative data. Users could accept or reject these suggestions, allowing the program to learn and improve its code suggestions over time. This early incorporation of AI in CAQDAS laid the foundation for future developments in the field.

Another notable CAQDAS tool that harnesses AI is DiscoverText. This platform offers features like automatic duplicate detection and near-duplicate clustering, which are analogous to plagiarism detection. Additionally, DiscoverText uses machine-learning coding tools based on initial human coding, which is undertaken collaboratively by peers. The results are then used to train a machine classifier that scores the likelihood of additional data falling into specific categories and codes accordingly.

Provalis Research, a prominent developer of analytic products, offers tools like QDA Miner and WordStat for qualitative analysis and data mining of textual material. These tools incorporate both unsupervised and supervised machine learning models. Unsupervised approaches include topic extraction using clustering, clustered coding, and topic modeling. On the other hand, supervised machine learning techniques such as automatic document classification, query-by-example, and code similarity searching are also available. These features enhance the efficiency and accuracy of qualitative analysis.

Leximancer, developed in 2000, is another AI-driven tool for automatic content analysis. It utilizes unsupervised machine learning to generate concept models of textual material and presents them in visualizations of categories and relationships. This visualization approach aids researchers in gaining insights and identifying patterns within their qualitative data.

AI has also made strides in the realm of transcription. NVivo Transcription and Quirkos Transcribe are examples of CAQDAS tools that employ AI-driven automated transcription capabilities. These tools automate the transcription process, saving researchers significant time and effort.

Furthermore, AI has proven useful in data summarization. ChatGPT, a language model developed by OpenAI, can summarize large amounts of data that would be impossible for a human to analyze comprehensively. Researchers can use ChatGPT to extract key information from transcripts or coded data, generate ideas for coding frameworks, and define codes. This AI-powered summarization serves as a precursor to further analysis using tools like NVivo.

Recognizing the potential of AI, several CAQDAS tools have integrated AI features into their offerings. ATLAS.ti, for instance, has released a beta version of its Open-AI powered "open coding" feature. This feature automatically suggests and codes selected textual transcripts, streamlining the coding process.

MAXQDA has also introduced an "AI Assist" tool in its beta version. This tool enables the creation of different levels of summaries, providing researchers with a quick overview of their data.

CoLoop takes a different approach by acting as an "AI Copilot" for qualitative research. This tool allows users to ask questions of their data using AI prompts through a chat function. Researchers can upload transcripts or other textual material and receive AI-generated summaries based on specific prompts. The underlying qualitative data is accessible and navigable within the system, allowing for a comprehensive analysis. CoLoop also includes AI-generated transcription capabilities, making it a versatile tool for qualitative researchers.

While AI has undoubtedly revolutionized the CAQDAS field, there are still challenges to overcome. One such challenge is ensuring the reliability and accuracy of AI-generated suggestions and codes. Researchers must exercise caution and critically evaluate the outputs of AI tools to avoid potential biases or errors.

In conclusion, AI has become an integral part of qualitative data analysis. From automated coding to data summarization, AI-driven tools have enhanced the efficiency and effectiveness of CAQDAS. Researchers can now manage large volumes of evidence with greater ease and obtain valuable insights quickly. However, it is essential to approach AI tools with a critical mindset and leverage their capabilities while remaining mindful of potential limitations.
