Dictionary making for data analysis

We are looking for talents who could help us make a keywords dictionary in order to make further analysis. We would provide you with some Projects Descriptions, what you should do is to identify what kind of industry these projects belong to, what keywords belong to one certain classified industry and what keywords may seem similar but should be excluded. This would be a long-term project as we have millions of projects descriptions. We would distribute these projects to different freelancers and pay according to the amount and quality. We would provide you with some project descriptions, then you could give us a demo analysis from your understanding of this task. After your showing your good understanding ability, we would discuss in details and start the project.
