Having spent quite a lot of time going through the literature on my research topic, I've been disappointed by the search features offered by the dominant academic databases and search engine (Web of Science, Scopus, Google Scholar etc...).
The search feature remains pretty basic and allows us to search by common theme.
We cannot search for ideas shared between papers, how one paper contradicts or supports another, or create nodes graphs by citations etc... I've thus relied on doing Knowledge Extraction by myself, but I'm sure someone has encountered these issues before.
Has anyone found a better tool or approach ?
