Beschreibung

Information retrieval is a central and essential activity. It is indeed difficult to find a human activity that does not need to retrieve information in an environment which is often increasingly digital: moving and navigating, learning, having fun, communicating, informing, making a decision, etc. Most human activities are intimately linked to our ability to search quickly and effectively for relevant information, the stakes are sometimes extremely important: passing an exam, voting, finding a job, remaining autonomous, being socially connected, developing a critical spirit, or simply surviving. The author of this book presents a summary of work undertaken over several years relative to the behaviors and cognitive processes involved in information retrieval in digital environments. He presents several examples of theoretical models and studies to better understand the difficulties, behaviors and strategies of individuals searching for information in digital environments.

Information Retrieval in Digital Environments: Debate and Scientific Directions

1.1. Information retrieval, current and future challenges

Information retrieval is a central and essential activity. It is indeed difficult to find a human activity that does not need to retrieve information in an often increasingly digital environment: moving and navigating, learning, having fun, communicating, informing, making a decision, etc. Most human activities are intimately linked with our ability to search quickly and effectively for relevant information, the stakes are sometimes extremely important: passing an exam, voting, finding a job, remaining autonomous, being socially connected, developing a critical spirit or simply surviving.

From the psychological point of view, the activity of information retrieval presents several characteristics that make them both unique, complex and fascinating [DIN 12a]:

– Information retrieval in digital environments is a necessity in a growing number of human activities. Daily, we must search for information (an address, a phone number, a time slot, a name, etc.) in various digital environments of constant evolution (GPS, mobile phone, Website, electronic terminal, etc.).

– Information retrieval is a composite activity, which typically requires reading, memorizing, writing, taking decisions, etc., these activities being cognitively complex and corresponding to areas of scientific research on their own.

– Information retrieval is a dynamic activity in the sense that the environment in which the activity is carried out evolves independently of the actions of the user (the same query in a search engine on the Web gives different results in an interval of a few seconds).
