What are good ways to explore/discover literature visually, e.g. a visual interface for Google Scholar? There are a few tools to explore the citation graph ("which papers cite which papers"). Some are described here:
There are a few more with a different focus:
- Graph of patents (but not papers) - "PatGraph"
- Only for own local library (not for discovery of new papers) - "Action Science Explorer"
- Old limited version from 2004 (no way to go backwards through citations) - "TouchGraph browser for Google Scholar"
- Limited database size - https://nlp.fi.muni.cz/projekty/visualbrowser/#sec0403
Do you know others? Which ones do you recommend?
