Describing the Information Seeking Behavior: An Investigation on Comparing Learning Models Using Experimental Data Sets/DESCRIPTION DU COMPORTEMENT DE LA RECHERCHE D'INFORMATION : UNE INVESTIGATION SUR LA COMPARAISON DES MODÈLES D'APPRENTISSAGE EN UTILISANT L'ENSEMBLE DE DONNÉES EXPÉRIMENTALES

Article excerpt

Abstract:

The purpose of this paper is to investigate the rule and characteristics of ACADEMIC users' information seeking behavior, as well as primary factors which influencing satisfaction and behavior outcomes as consequences of the value of information seeking. To examine the users' behavior, several learning models were adopted, such as Bush-Mosteller model, Bayesian model,, fictitious play and EWA model.

Here we employ both qualitative and quantitative approaches to examine the phenomenon of information seeking. We tried to compare the consistence of different models on the basis of experimental data. In Nanjing University of Science and Technology, 120 students were randomly assigned to three different teams and provided different communicating environment according to different learning models when seeking same assign for two hour.

The result of a series of confirmatory factor analyses reveals that users' satisfaction and behavior outcomes had correlated factors with moderate to good reliability. The findings from model analyses showed that EWA are more adapted to the others.

Résumé: Le présent article vise à étudier les règles et caractéristiques du comportement de la recherche d'information des utilisateurs académiques, et les facteurs essentiels influant sur les résultats de satisfaction et de comportement en raison de la valeur de la recherche d'information. Afin d'examiner le comportement des utilisateurs, plusieurs modèles d'apprentissage ont été adoptés, tels que modèle Bush-Mosteller, modèle Bayesian, jeu fictif et modèle EWA.

Nous employons ici à la fois les approches qualitatives et quantitatives pour étudier le phénomène de la recherche d'information. On tente de comparer la cohérence de différents modèles sur la base des données expérimentales. A l'Université de Sciences et Technologie de Nanjing, 120 étudiants distribués au hasard dans 3 groupes ont offert, pour les mêmes tâches de recherche de 2 heures, de différents environnements de communication en vertu des modèles d'apprentissage distincts.

Le résultat d'une série d'analyses sur les facteurs confirmatoires montre que les résultats de satisfaction et de comportement ont corrélation avec la moyenne et la grande fiabilité. Les résultats des analyses de modèles indiquent que EWA s'adapte mieux à d'autres.

1. INTRODUCTION

More and more database companies pay attention to academic users and it is becoming an important issue. As for database companies, in order to attract more users, they have to put in tremendous effort to concerning their needs and preference. Because of the importance of that problem, this paper investigated academic users' information seeking behavior from the learning behavior perspective and also concerned the consistence of learning models.

Generally speaking, learning is an universal phenomenon in the world. It is a process that all kinds of animals obtain individual behavior experience. Narrowly speaking, learning only mean the human learning behavior. Mainly through language as intermediary to master social experience and it is a positive process. Psychologists started to study learning processes extensively approximately 100 years ago. At that time, psychology was dominated by the view that processes within the brain cannot be studied and that explanations of behavior should be based purely on observable variables. In the 1950s psychologists started a new line of research into learning processes. They studied the impact of social interaction and observation on learning and divided learning only into two fundamentally different ways(Thomas Brenner, 2005). First, humans share with other animals a simple way of learning, which is usually called reinforcement learning. This kind of learning seems to be biologically fixed. …
