Developing ontologies that capture the inherent vagueness in human language can improve the accuracy and naturalness of human-computer interaction, particularly in systems that interpret user commands or analyze human actions. This human factors research insight is drawn from a 2013 study published in White Rose eTheses Online (University of Leeds, The University of Sheffield, University of York). Using Ontological formalization and system development, researchers explored how this design variable affects real-world outcomes. The key design takeaway: When designing interfaces or systems that rely on understanding human input or actions, consider formalizing ambiguous terms to improve system accuracy and user experience.

Key Findings
- 01A methodology for the semantic characterization of vague and qualitative concepts was developed.
- 02A supervaluationist approach is effective for formalizing vague concepts.
- 03The developed ontology and system (ProVision) demonstrated practical applicability in inferring event occurrences from video data.
Application
Design takeaway
When designing interfaces or systems that rely on understanding human input or actions, consider formalizing ambiguous terms to improve system accuracy and user experience.
How to apply
When designing voice command interfaces or gesture recognition systems, create a formal lexicon that includes definitions for commonly used vague terms, allowing the system to interpret a wider range of user inputs more accurately.
Project actions
- 01When defining user requirements, explicitly consider how vague terms might be interpreted differently by users and the system.
- 02Explore how to represent qualitative user feedback (e.g., 'it feels a bit slow') in a quantifiable way for design analysis.
Method & Evidence
Variables
Strengths & Limitations
Strengths
- +Provides a novel methodology for handling linguistic vagueness in formal systems.
- +Demonstrates practical application through a working system (ProVision).
Limitations
The complexity of real-world scenarios and the sheer volume of potential ambiguities in human language can make comprehensive formalization challenging.
Reliability & validity
The reliability of the system would depend on the consistency of the ontological definitions and the input data. Validity would be assessed by how accurately the system infers events compared to human judgment.
Think critically
To what extent can a formal ontology truly capture the subjective and context-dependent nature of vague human language, and what are the trade-offs in terms of system complexity versus user experience?
Design Principles
"Embrace and formalize ambiguity in human language to enhance system understanding and interaction."
Many design projects involve interpreting user input or understanding human behavior. By formally representing ambiguous terms like 'near' or 'fast,' designers can create systems that are more robust and less prone to misinterpretation, leading to a more intuitive and effective user experience.
What This Means for Your Design
This research shows how to teach computers to understand fuzzy words like 'close' or 'fast' by creating a structured dictionary of meanings, which helps them recognize what's happening in videos.
How to use in your project
- 1.Use the concept of ontological formalization to justify the design choices for how your system interprets user input or analyzes user behavior.
- 2.Discuss how your design addresses potential ambiguities in user language or actions.

Paragraph starter
This research highlights the importance of formalizing vague language for improved system understanding. By developing an ontology that captures the nuances of terms like 'near' or 'fast,' systems can more accurately interpret user input and recognize events, leading to more effective human-computer interaction. This approach is relevant to the design of intuitive interfaces and intelligent systems that aim to bridge the gap between human expression and machine comprehension.
