Emotions form an important component of human behaviour and decision making and thus are an essential part of context-aware web-based decision support systems. In this paper a conceptual model based on sensemaking, affective and situational feedback is outlined for design of context-aware web-based decision support systems. An application of the model is illustrated in the area of web-based behaviour profiling and recruitment of salespeople. In this application cognitive responses of a sales candidate to behavioural questions from a e-Sales Recruitment and Benchmarking System (e-SRBS) are mediated with their real-time emotional or affective responses to facilitate context-aware decision support in e-recruitment applications. . The work reported has implications in not only e-recruitment but also in knowledge management, data mining, web personalisation and context-aware web-based decision support systems in general.
