GATE Developer - an Introduction

These are 7 videos that give you a basic introduction to the GATE Developer application. They go from the basic introduction to GATE Developer user interface, through loading and working with GATE documents, until creating your own GATE Application with CREOLE resources. Each video is built upon information learnt from a previous video. You can also jump directly into a video if you feel that you have the necessary knowledge as mentioned in the "What you should know before you start this module" section of that video.

Each video has a specific subject, which you will find in the "What you will learn" section for each of them.
