When Agents Make Suggestions About Readings Orlando Belo Algoritmi R&D Centre, University of Minho, Portugal obelo@di.uminho.pt Abstract: Significant efforts have been made during the last few years in the design and implementation of pedagogical agents for a wide range of application domains. One of the most common target area is the assistance to students in cases of regular subject studying, promoting means that help them to improve their performance and expertise in some specific subject areas. Frequently students ask their teachers about the “best” and more effective bibliographic resources that they could use to study and validate knowledge for some working topics. In this paper we will discuss the basic characteristics of pedagogical agents, approaching their typical functional architecture, and services, reinforcing the discussion on a specific class of pedagogical agents that are responsible to support students during their studying sessions, helping them in the validation of their knowledge, suggesting bibliographic resources information whenever requested. Keywords: eLearning platforms, agent based computing, intelligent tutoring systems, software agents, artificial intelligent tutors, bibliographic resources suggestion 1. Introduction Agent based applications are very appellative. Software agents have been used to support a lot of tasks in real world applications (Van der Hoek & Wooldridge 2008). Ranging from telecommunications to retail, or doing monitoring services on hydroelectric power plants, agent based computing has been always a very good asset in a lot of problem solving arenas. eLearning is no exception to this attractive paradigm and to all of its characteristics and potentialities (Agarwal et al. 2004) (Leung & Li 2001). One of the most relevant agent applications on this field was in the design and development of pedagogical agents, normally designed by artificial tutors or intelligent assistants. Basically, these entities are conceived to ensure more effective tutoring services, in some very specialized areas of studying, having clearly pedagogical purposes, giving assistance to students in cases of regular subject studying or even doing evaluation tasks. Additionally, they are also able to perform administrative and optimization services inside eLearning platforms, supervising what users are doing and suggesting better ways to do it or recommending particular resources that can help them in current tasks. The use of software agents as sophisticated autonomous means helping students on bibliographic resource selection seems to be very useful and appellative. The ability that agents have to adapt to new scenarios and to communicate with other means of learning makes possible a very dynamic eLearning environment, where students needs can be satisfied easily. An agent can also adapt in real time different plans of readings for current user needs, finding the best solution for a given studying plan, and personalizing processes and exploitation scenarios (Schiaffino et al. 2008). To do that, they simply need to act as search engines over their databases looking for a list of references that satisfies student current, his preferences, and a previous plan of readings prepared by his teachers. This means that any assistant agent (Okamoto et al. 2009) must establish usage profiles and accordingly prepare its plan of action an user satisfaction. It is very desirable that the processes of readings suggestion is versatile and proactive, providing the references that students require and, at the same time, giving viable alternatives that follow other suggestion indicators (e.g. readings usage ranking, recommended references, teacher’s preferences, or external sources identification). In this paper we will focus our attention on a specific class of pedagogical agents that are responsible to support students during their studying sessions, helping them in the validation of their knowledge in a particular domain, and (as their priority goal) suggesting bibliographic resources information whenever requested or inferred as necessary during an evaluation process, accordingly current studying status of the students. We will discuss the basic characteristics of these pedagogical agents (section 2), reinforcing the discussion presenting an application domain for bibliographic resource suggestion in a conventional eLearning scenario (section 3), and present the basic characteristics and functional architecture of a specific software agent for personalised assistance in bibliographic resource suggestion (section 4). Finally, in section 5, we will present some conclusions and future work. 41
