A picture of myself at the Chinese Great Wall

I build computational models of human behaviour on the Web. My work is about identifying the strategies users adopt when they face challenging situations that occur either because they are dealing with complex logical artefacts (ie, ontologies) or because they are constrained by their abilities, skills or the situation when they navigate on the Web. Then we develop computational solutions to automatically detect these strategies in real time. As a result we can detect problematic interactions.

In the "What if..." EPSRC project we are exploring the difficulties encountered by ontology authors in the ontology building process, where building indicates (not only) reusing, merging, modifying, evaluating and reasoning with ontologies. The final goal of the whatif project is to provide ontology authors with tools that adjust to their needs based on observed behaviours.

In the COPE project, we are investigating the similarities between edge-interaction cases undergone by able-bodied users and the coping situations faced by visually disabled users. We have found evidence suggesting there is an overlap between the problems and strategies employed by these two populations.

I received a PhD in Computer Science at the University of the Basque Country on web accessibility assessment, evaluation and measurement. I keep active in the field and publish papers about defining web accessibility, the limitations of web accessibility evaluation tools, the perception of web accessibility by proffessionals and the role of expectations on user tests.

I am a member of the W4A Conference steering committee and the W3C RDWG. The W3C Research Report on Web Accessibility Metrics is one of our latest efforts in injecting research outcomes into standardisation bodies.

Overcoming the pitfalls of ontology authoring: strategies and implications for tool design

Markel Vigo, Samantha Bail, Caroline Jay and Robert Stevens

International Journal of Human Computer Studies

The process of authoring ontologies is fragmented across several tools and workarounds, and there exists no well accepted framework for common authoring tasks. We present insights from an interview-based study with 15 ontology experts: we uncover the tensions that may emerge between ontology authors and identify the problems and the strategies the authors employ to solve them.

Protégé4US: Harvesting Ontology Authoring Data with Protégé [Best paper award]

Markel Vigo, Caroline Jay and Robert Stevens

Workshop on Human-Semantic Web Interaction, HSWI 2014

We propose an instrument that allows harvesting of ontology authoring events and interaction events. A study with 15 users carrying out ontology authoring tasks suggests that Protégé4US has an enormous potential to expand our knowledge about the ontology authoring process, identify its pitfalls, propose design guidelines and develop intelligent authoring tools that anticipate user actions.
