Semantic Searching using MEDIE

From Nodalpoint :

MEDIE is an "“intelligent" semantic search engine that retrieves biomedical correlations from over 14 million articles in MEDLINE. You can find abstracts and sentences in MEDLINE by specifying the semantics of correlations; for example, What activates tumour suppressor protein p53?

What is does is identify the subject, verb and object of concepts in the articles. For example, using "inhibits" as verb and "enoyl reductase" as object pulls up valid entries such as:

Triclosan acts by blocking enoyl acyl carrier protein reductase , an enzyme essential for fatty acid biosynthesis.

In this case, blocking is semantically equivalent to inhibits. It even color codes the subject, verb and object in the results!

I wish this were available for chemical information, although QueryChem does something similar for molecule searches.
