Pronunciation variation is extremely widespread and one of the reasons for recognition errors. In this paper we explore how similar-recognized-words can be used to construct or expand more accurate grammars in a specific domain. The domain that serves as framework for this research is the assessment of depression. Assessment of depression is done via a system that verbally administers a discret...

In this paper we introduce the fare planning problem for public transport which consists in designing a system of fares maximizing revenue. We propose a new simple general model for this problem. It is based on a demand function and constraints for the different fares. The constraints define the structure of the fare system, e.g., distance dependent fares or zone fares. We discuss a simple exam...

Background In trial design, decisions are made about which intervention components/processes to standardise and which remain flexible to maximise utility and/or effectiveness. The intervention-context-system fit for complex interventions impacts on trial recruitment, delivery and outcomes. Survey vignettes and discrete choice experiments are quantitative researcher led approaches which focus on...
