This article examines a simple model of an information retrieval (IR) technology, and uses this model to examine the optimal use of such a technology. In particular, we show that, if we understand optimal behavior, then we can (a) use observed behaviorto shed light on the user's objective function, and (b) analyze how a user's behavior changes as her environment changes, for various specifications of the user's objective function. We also show how user satisfaction varies with the underlying stochastic behavior of the retrieval process.

A linguistic model for an Information Retrieval System (IRS) defined using an ordinal fuzzy linguistic approach is proposed. The ordinal fuzzy linguistic approach is presented, and its use for modeling the imprecision and subjectivity that appear in the user-IRS interaction is studied. The user quer
Most information retrieval systems based on linguistic approaches use symmetrically and uniformly distributed linguistic term sets to express the weights of queries and the relevance degrees of documents. However, to improve the system-user interaction, it seems more adequate to express these lingui
