ARCSYS: Accès et recollection dans les systèmes d’information complexes


In the context of Web interaction, memory and remembering are particularly important: individual pages are revisited and new pages are constantly added to the repertoire of visited pages. In order to revisit one page, we need to recollect what was on that page and also planning how to navigate to that page demands access to episodic memories of interaction with that web site. Retrieving information from memory represents a problem for
web interaction, and older internet users may eventually show impaired ability to retrieve the context of previously seen items, their source, thereby leading eventually to a disorientation problem. Not only retrieving information from episodic memory is ecologically sound, because Web users commonly re-visit pages they have found earlier, but information
re-access, the situation where the user found a piece of information earlier and now the same information is needed again, is one aspect missing from the existing models of information searching (e.g., Bates, 1999; Pirolli & Card, 1999).

In this fundamental research project, partners share the assumption that emphasizing
similarities between human memory and information retrieval can yield better cognitive models and better applications. Many experiments conducted by psychologists and ergonomists, computer scientists and information retrieval specialists are proposed, in which participants will interact with, access, remember, and eventually re-access contents. The contents consist in text(s) and are displayed by means of individual Web pages, a series of short documents on the same topic, bibliographic references accessed through an online
reference management system (Connotea), a large collection of texts taken from the Text REtrieval Conference (TREC) series that will be retrieved with a flexible search engine.

The main goal of this research project is to develop a model of the long-term memory representations constructed as part of Internet users' navigation, access and processing of complex documents in digital information systems. Dual-memory processes have been described as implicit versus explicit, recollection versus familiarity, verbatim-based and gist-based judgements in the memory literature. However, these retrieval processes have been neglected in prior research on interactions with digital information.
