One of the options for performing NER is the use of the Chemical Tagger NER algorithm (for more details please visit http://gate.ac.uk/sale/tao/splitch21.html#sec:parsers:chemistrytagger ).
Selecting the Corpus object on the clipboard, you should right click over it an choose Corpus -> NER -> Chemical Tagger
A GUI will be presented, where you can select tagger sources:
- Ion(e.g. Fe3+, Cl-).
- Compound formulas (e.g. SO2, H2O, H2SO4 ...).
- Element names and symbols (e.g. Sodium and Na).
Pressing Ok the operation will be launched and a progress window will be shown, indicating the execution of the operation and estimate time left. The NER operation will take a few minutes or hours depending on the number of documents, document size and used resources.
When the process terminates, a new NER Process object will be added to the clipboard and be visualized through the Corpus Process View.
