Perspectives around the cognitive model for the information retrieval: a critical analysis / Enfoques en torno al modelo cognitivo para la recuperación de información: análisis crítico

The traditional or algorithmic model of information retrievalhas evolved into the cognitive model. From the latter, differentproposals for practical implementation have arisen being the most remarkable ones those labelled by their own authors asGlobal Model of Polirepresentation, Episodic Model, StratifiedModel and Model of Interactive Feedback. These are criticallydescribed and analysed in this paper

Incorporating aspects of information use into relevance feedback

In this paper we look at some of the problems in interacting with best-match retrieval systems. In particular, we examine the areas of interaction, some investigations of the complexity and breadth of interaction and attempts to categorise user's information seeking behaviour. We suggest that one of the difficulties of traditional IR systems in supporting information seeking is the way the information content of documents is represented. We discuss an alternative representation, based on how information is used within documents
