The Internet is full of information sources providing various types of data from weather forecasts to travel deals. These sources can be accessed via web-forms, Web Services or RSS feeds. In order to make automated use of these sources, one needs to first model them semantically. Writing semantic descriptions for web sources is both tedious and error prone.
EIDOS is a system that can generating such models automatically. It provides a framework for learning Datalog definitions for new web sources in terms of known information sources. The paper Learning Semantic Descriptions of Web Information Sources describes the theory behind the system.
After filling out the form below, just download EIDOS.zip and unzip it. From there, all instructions for configuring the system to run are presented in detail in the README.txt file. To save you some time, you will need Java (1.5 or higher) and MySQL to run the software. Please direct all inquiries here.
