Describing the Information Seeking Behavior: An Investigation on Comparing Learning Models Using Experimental Data Sets

Chen BAI, Li-ren GAN

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.
Key words: learning model, information seeking, academic user
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.
Mots-Clés: modèle d’apprentissage, recherche d’information, utilisateur académique
