Entity types via the API
The tagcat parameter specifies the entity class. Currently the following entity classes are available:
|Entities related to anatomy, e.g. blood, neurons, etc.
|Emerging technology (click here to see the topics)
|Events like conferences
|Financial investors and institutions
|International Patent Classification (using CPC codes)
|Locations, mainly names of towns and cities
|Chemical compounds, as described e.g. in PubChem
|Entities related to organisms, e.g. bacteria, rats, Staphylococcus
|Governmental and research institutions, universities
|Names of persons
Entity classes can be combined with the pipe operator, e.g. tagcat=Company|Person. This is useful to analyze the relationship between entities.
