By the time of this post, I am a student writing my bachelor thesis on knowledge-based argumentation graph and entity linking. Basically it deals with how two or more similar arguments in graph can be merged and how much improvement such operation can produce in terms of creating new information from the graph. I tried Neo4j as my graph storage because apparently it has large active community and easily accessible tutorials.
I am very new to this kind of system so I will be more likely posting questions rather than answering them. But I will try my best to contribute to the community.
