How to automatically capture a significant portion of relevant background knowledge and keep it up-to-date has been a challenging problem encountered in current research on logic based information retrieval. This paper addresses this problem by inves... Read More about Concept learning and information inferencing on a high-dimensional semantic space..

Diminishing awareness is a consequence of the information explosion: disciplines are becoming increasingly specialized; individuals are becoming ever more insular. This paper considers how awareness can be enhanced via abductive knowledge discovery t... Read More about Abduction in semantic space: towards a logic of discovery..

We propose an intelligent document title classification agent based on a theory of information inference. The information is represented as vectorial spaces computed by a cognitively motivated model, namely Hyperspace Analogue to Language (HAL). A co...

Humans can make hasty, but generally robust judgements about what a text fragment is, or is not, about. Such judgements are termed information inference. This article furnishes an account of information inference from a psychologistic stance. By draw... Read More about Towards context-sensitive information inference..

Inferring query models by computing information flow. (2002)
Conference Proceeding

The language modelling approach lo information retrieval can also be used lo compute query models. A query model can be envisaged as an expansion of an initial query. The more prominent query models in the literature have a probabilistic basis. This... Read More about Inferring query models by computing information flow..
