Intelligent Agent, Information Filtering And Avatar

Description

ABSTRACT

This seminar paper discusses of Better ways at finding the most valuable information on the Internet, and to avoid trash. This paper makes an overview of methods and problems in this area, including social filtering, where people help each other with filtering objects on the net. The paper also discusses about the intelligent agent in the IT environment, and how they work. Finally, the computer avatar was discussed and ways to which it was employed were delineated.

CHAPTER ONE

(1.0)  INTRODUCTION

This seminar discusses on the intelligent agent, information filtering and avatar. In artificial intelligence, an intelligent agent (IA) is an entity, which observes and acts upon an environment (i.e. it is an agent) and directs its activity towards achieving goals (i.e. it is rational). Also it is seen that finding the most valuable information on the Internet, and to avoid trash, would very much enhance the value of the network. This seminar makes an overview of methods and problems in this area, including social filtering, where people help each other with filtering objects on the net. And finally the avatar, which refer to the personality connected with the screen name, or handle, of an Internet user

CHAPTER TWO

(2.0) INTELLIGENT AGENT

An intelligent agent (IA) is an entity, which observes and acts upon an environment (i.e. it is an agent) and directs its activity towards achieving goals (i.e. it is rational).

(2.1) VARIETY OF DEFINITIONS

[1] Intelligent agents may also learn or use knowledge to achieve their goals. They may be very simple or very complex: a reflex machine is an intelligent agent, as is a human being, as is a community of human beings working together towards a goal. Intelligent agents are often described schematically as an abstract functional system similar to a computer program. For this reason, intelligent agents are sometimes called abstract intelligent agents (AIA) to distinguish them from their real world implementations as computer systems, biological systems, or organizations. AIA is an entity which exhibits an essence of human-like intelligence and, as an IA, may have numerous other properties resulting from the properties of its carrier physical or software system (A.M. Gadomski, 1993).

For this reason IA can be either rational or emotive/irrational or, according to Herbert Simon, it represents bounded rationality.

Some definitions of intelligent agents emphasize their autonomy, and so prefer the term autonomous intelligent agents. Still others (notably Russell & Norvig (2003)) considered goal-directed behavior as the essence of rationality and so preferred the term rational agent.

In order to separate necessary and not necessary properties of IA, in the computational TOGA meta-theory [2], every cognitive AIA acts on the base of its/his/her available information, possessed preferences and knowledge (IPK model) with a different range, on various abstraction levels, and in different domains of activity. Such agent is called personoid. The quality of application and processing of its information, knowledge and preferences depends on the characteristics of AIA’s carrier system, i.e. memory available, velocity and other its structural properties. According to different I, P, K bases, IA may be specialized for numerous roles.

Intelligent agents are closely related to agents in economics, and versions of the intelligent agent paradigm are studied in cognitive science, ethics, the philosophy of practical reason, as well as in many interdisciplinary socio-cognitive modeling and computer social simulations.

Intelligent agents are also closely related to software agents (an autonomous software program that assists users). In computer science, the term intelligent agent may be used to refer to a software agent that has some intelligence, regardless if it is not a rational agent by Russell and Norvig’s definition. For example, autonomous programs used for operator assistance or data mining (sometimes referred to as bots) are also called “intelligent agents”.
