I want to make commercial knowledge graph search engine. It will retrieve structured and connected data (raw linked text, multimedia files, Youtube videos, images, and so on) that both computers and people will be able to read and understand. I am using Django framework, mongoDB and I will deploy engine on Heroku. I have graph model and will soon have first prototype. I want to crawl the Internet, do data mining and use machine learning techniques to extract and understand data in order to update knowledge base. In later stages of this project I will use NLP, Latent Semantic Analysis and other techniques so that users would be able to make more complex queries.
