PubNet (Publication Network Graph Utility) is a web-based tool that extracts several types of relationships returned by PubMed queries and maps them on to networks, allowing for graphical visualization, textual navigation, and topological analysis.

Semantic Medline is a web application that uses natural language processing to exract semantic predications from a PubMed search. Resutls are presented as an interrelated network of concepts.

 Quertle retrieves information within the biomedical literature by using its own semantic database of 300 million relationships.

NextBio (Literature) Uses a tag cloud approach to help discovering the most important concepts resulting from a query.

Coremine presents search results as a graphic network that describes relationships discovered through text-mining. Relationship networks provide an overview of a topic by clustering important terms. The network is also a navigational tool that can help searchers explore concepts related to their search term.

Chilibot searches PubMed literature database (abstracts) about specific relationships between proteins, genes, or keywords presenting the results as networked relationships.
