Indexing and retrieval performance: the logical evidence
TLDR
The ability to ask the questions one needs to ask as the foundation of performance evaluation, and recall and discrimination as the basic quantitative performance measures for binary noninteractive retrieval systems are established.Abstract:
This article presents a logical analysis of the characteristics of indexing and their effects on retrieval performance. It establishes the ability to ask the questions one needs to ask as the foundation of performance evaluation, and recall and discrimination as the basic quantitative performance measures for binary noninteractive retrieval systems. It then defines the characteristics of indexing that affect retrieval—namely, indexing devices, viewpoint-based and importance-based indexing exhaustivity, indexing specificity, indexing correctness, and indexing consistency—and examines in detail their effects on retrieval. It concludes that retrieval performance depends chiefly on the match between indexing and the requirements of the individual query and on the adaptation of the query formulation to the characteristics of the retrieval system, and that the ensuing complexity must be considered in the design and testing of retrieval systems. © 1994 John Wiley & Sons, Inc.read more

How many relevances in information retrieval
TL;DR: There are many kinds of relevance, not just one, and these kinds can be classified in a formally defined four dimensional space, and such classification helps to understand the nature of relevance and relevance judgement.

The influence of surface and deep cues on primary and secondary school students' assessment of relevance in Web menus
TL;DR: In this article, the authors investigated primary and secondary school students' web menu selection strategies using simulated web search tasks and found that 5th and 7th graders' selections were strongly influenced by superficial relevance cues.

A definition of relevance for information retrieval
TL;DR: A definition of what it means to say that a piece of stored information is “relevant” to the information need of a retrieval system user is proposed and defended and explicates relevance in terms of logical implication.

On selecting a measure of retrieval effectiveness
TL;DR: It is argued that a user's subjective evaluation of the personal utility of a retrieval system's output to him, if it could be properly quantified, would be a near-ideal measure of retrieval effectiveness.

Effectiveness of information retrieval methods
TL;DR: Results of some 50 different retrieval methods applied in three experimental retrieval systems were subjected to the analysis suggested by statistical decision theory and validates a previously‐proposed measure of effectiveness and demonstrates its several desirable properties.
