Information retrieval (IR) and the paradox of change: An analysis using the philosophy of Parmenides

Purpose To explore whether philosophical insights from Plato’s dialogue ‘Parmenides’ on the complex and often paradoxical nature of change can illuminate the nature of information retrieval (IR). IR is modeled as a dialectic process involving mutually dependent yet conflicting forces between the subjective and the objective. These forces operate to produce change in the subjective experience of users (becoming informed) through facilitating a relationship with objective documents. Accurately modeling, predicting and enabling this process remains a persistent problem for IR and this paper examines the extent to which this is because of the nature of change. Methodology/Approach Conceptual analysis and literature review. Findings The problem of change (what it is, how it happens and how we can know it has happened) is essential to our understanding of information as information normally implies some kind of change in knowledge state. Any process of change, however, on examination of its qualities, appears to necessitate the combination of irreconcilable and conflicting forces. The apparent contradictions within the existence of change as discussed in ‘Parmenides’ also exist in IR on both a theoretical and a technical level. Research Implications Change is a central concept for information in general and IR in particular. A deeper understanding of the paradoxical nature of change can provide new insights into IR theory and practice. 2 Originality/value of paper Presents a new historical philosophical perspective on the nature of change and applies it to current IR problems.
