Chemical Named Entity Recognizer
This services annotates chemical named entities using the open source OSCAR4 tagger.
More details on OSCAR4, including a number of example texts, can be found in this publication. One simple example, from that paper would be "The quick brown ethyl acetate jumps over the lazy bromine" which results in two annotations over ethyl acetate and bromine.
- type: the type of NE. Usually 'compound'
- Std_InChI: The standard International Chemical Identifier for the recognised NE.
- Std_InChiKey: A hashed version of the Std_InChi key useful for web searches etc.
- SMILES: The named entity described using the simplified molecular-input line-entry system (SMILES)
