Objective This project is about a study of evolution and ecology of interacting infohabitants. We will study a population of infohabitants, with carefully designed interaction. An ontology will be defined, and soft computing used as a model for interaction. Properties to be studied are scalability, openness, adaptability, and stability. We aim at deriving concrete results that can be used in the design of universal information ecosystems. A demonstrator will be constructed as well.OBJECTIVESOur main objective is to study the ecology of a system of interacting intelligent infohabitants, especially the scalability, openness, adaptability, and stability of the ecosystem. A sub-objective is to define intelligent interaction, or interaction of intelligent infohabitants. Another sub-objective is to study how the complexity of interaction of the infohabitants influences the behaviour of the ecology. Another sub-objective is to find what are the properties of the ecology of infohabitants that are worth studying. Another sub-objective, related to scalability, is the openness with respect to integration of new types of intelligent infohabitants. Our last technical sub-objective is the specification of conditions of stability of the ecosystem. Validation is also an objective of our project.DESCRIPTION OF WORKWe will determine the convergence time of a system of interacting intelligent infohabitants. We will relate this time to the communication time, and the communication load. The infohabitants interact using soft computing. We will simulate this, and then derive a scaling law of the convergence time as a function of the number of infohabitants. We will grow the emergent ontology by simulation in a stable system and the environment will be partitioned in certain habitats. We will study the impact upon the ontology by the inclusion or exclusion of infohabitants, and by the extension of the behaviour of the infohabitants. Our learning infohabitants comprise:1. The learning element2. The performance element3. The critic4. The problem generator.We plan to use fuzzy deterministic descriptions. Find what feedback is available for the learning algorithm, and what prior knowledge is available. We will use the stability of agent systems via equilibrium distributions of stochastic processes. The characteristics of these stochastic pr0cesses have to be changed, because the infohabitants are now part of an ecosystem. We will do simulations, and some theoretical work. These results then have to be adapted to the use of fuzzy variables.Our electronic commerce process will have the following steps:Step 1. The user enters his requirements and desired factors in a computer, using a natural language form using the shared ontology to be developed in this projectStep 2. An infohabitant is dispatched to "shop around" entering the network an communicating electronically with other infohabitants and databases to locate and obtain the required informationStep 3. The infohabitants of the previous step will attempt to match the requirements against what is available, negotiating with vendor's nfohabitants. These infohabitants might activate others to make arrangements, co-operate with each other and make inquiriesStep 4. An infohabitant returns with one or more recommendations.
