  • Person - A living, dead or fictive person.
  • Organization - A company, department, organization or product.
  • Location - A geographical place.
  • Unknown - When we couldn't predict the category.
  • URL - An Internet- or mail address.

A tag also has a relevance value which indicates how important the tag is for the given text.

What will be extracted as a tag?

When you, through Saplo API, get the entity tags for a text they will by default be extracted exactly as they where written in the text. This means that if a name is misspelled or an entity are written twice but with different spelling both occurences will be extracted. E.g. If both “Washington” and “Washinton” exists in the text they will be extracted as two tags.
