Navigating Qualitative Data Analysis complexity using Word Clouds, Visual Trees and Graph Databases

Nov 16, 2023, Maniish Karve

At flowres.io, we are continuously developing our Qualitative Data Analysis (QDA) capabilities; to enhance relevance to our users’ needs. During user conversations, our users expressed the need to visualize Qualitative data better, to make QDA more efficient. This article focuses on 3 techniques that serve this very purpose:

·         Word Clouds

·         Visual Trees

·         Graph Databases

 

To begin with, we will touch upon the types and applications of each technique individually, before illustrating how they can synergistically generate deeper insights in the context of Pharmaceutical market research. Next, we'll delve into a compelling case study where these techniques converged, to answer a critical research question for our client.

 

Word Clouds Unveil Key Themes

Word clouds serve as a visual gateway to understanding the most frequently mentioned terms within a dataset. Thematic word clouds, for instance, quickly highlight prevalent themes in Qualitative data, offering a snapshot of priorities and concerns. Sentiment Analysis word clouds add another layer, by color-coding terms to represent positive, negative or neutral sentiments. Regulatory Compliance word clouds assist in identifying terms with potential regulatory implications, ensuring adherence to standards.

 

Visual Trees Map Relationships and Hierarchies

Visual Trees introduce a hierarchical structure to identified themes, showcasing relationships and connections between overarching themes and sub-themes within. For instance, a visual tree could illustrate how patient outcomes are connected to adverse events and treatment adherence in Pharmaceutical research.

 

Graph Databases Unravel Complex Networks

Graph databases excel at uncovering intricate networks that might rest within Qualitative data. In Pharmaceutical market research, these networks might include relationships between stakeholders eg. pharmaceutical companies, healthcare professionals and patients; or connections between non-clinical factors and treatment protocols. The nodes represent entities, and the edges signify collaborations, clinical trials, or regulatory interactions; thus providing a comprehensive visualization of the complex web of interactions.

 

 

Word Clouds, Visual Trees, and Graph Databases in Synergy

Having outlined the essence of each technique, let’s now look at how they can be used together, to generate insights from complex and voluminous Qualitative data.

The true power of these techniques lies in their integration. Consider a scenario where a pharmaceutical company wishes to understand factors influencing the selection of a treatment regimen. 

By leveraging word clouds, researchers can quickly identify key themes and sentiments associated with treatment preferences, adverse events and patient experiences.

Visual trees come into play when mapping out the relationships between these themes. For example, a visual tree might explain how patient experiences are linked to specific adverse events and treatment preferences. This structured representation adds depth to the understanding of the relationships uncovered by word clouds.

Graph databases further enhance the analysis, by unraveling complex networks influencing treatment selection. Nodes can represent clinical factors (eg. drug efficacy, side effects) and non-clinical factors (eg. patient demographics, regional considerations); whereas edges denote connections among these factors and their impact on treatment protocols. The integration of graph databases provides a holistic view of the multifaceted landscape that guides treatment decisions.

A word of caution – like with all QDA, it’s easy to get caught up in the method and the visualization; instead of focusing on the outcomes. And that is where tools like Flowres, with their visualization and insight exploration capabilities, can both simplify and accelerate the process.

 

Case Study: Decoding Treatment Regimen Selection Drivers

In a pharmaceutical market research study focused on metastatic non-small cell lung cancer (mNSCLC), the research question our client wanted answered was: What clinical and non-clinical factors are key drivers in selecting a treatment regimen? Let’s take a look at how the analysis progressed after data collection and preparation.

 

1.    Word Cloud Analysis: Thematic word clouds swiftly identified that the top 3 clinical factors were drug efficacy, treatment adherence and adverse events. Similarly, the top 3 non-clinical factors were patient demographics, geographical considerations, and socioeconomic influences. Further, Sentiment analysis word clouds offered insights into the emotional tone associated with different treatment regimens.

2.    Visual Tree Mapping: Building upon the themes uncovered by word clouds, researchers created a visual map to flesh out hierarchical relationships. The visual tree revealed sub-themes around the non-clinical factors driving the selection of an infusion based v/s an oral protocol

3.    Graph Database Exploration: Leveraging a graph database, we could map out the entire network of clinical and non-clinical factors influencing treatment selection. Nodes representing drug efficacy, patient demographics, and treatment preferences, with edges connecting these factors, illustrated their impact on specific treatment protocol selection.

 

Conclusion

In the dynamic realm of Pharmaceutical market research, the synergy of word clouds, visual trees, and graph databases creates a powerful trifecta for understanding Qualitative data in its entirety. This integrated approach goes beyond isolated analyses, providing a comprehensive and nuanced view of stakeholder perceptions, thematic hierarchies, and intricate networks. Harnessing the capabilities of these integrated tools is now becoming indispensable for pharmaceutical researchers aiming to influence data-driven decisions.  

The case study exemplifies how these techniques converge to answer critical research questions and guide informed decision-making in the complex landscape of treatment selection. Do continue to watch this space as we continue pushing the boundaries of QDA, to help our users efficiently achieve insight-rich outputs.
