Aspects of information access And mesuring Retrievability & Accessibility

Evaluation in Information Retrieval (IR) has long focused on effectiveness and efficiency. However, new and emerging access tasks now demand alternative evaluation measures which go beyond this traditional view. A retrieval system provides a means of gaining access to documents, therefore intuitively, our view of the collection is shaped by the retrieval system. In this paper, we outline some emerging information access related scenarios that require knowledge about how the retrieval system affects the users’ ability to access information. In this paper, we empirically explore the relationship between effectiveness and accessibility to determine whether the two objectives i.e. maximizing effectiveness and maximizing accessibility, are compatible, or not. this paper also proposes that the study of information access can be facilitated through the recognition and examination of the physical, intellectual, and social aspects of information access.
