Attributes

Token attributes

Token attributes are specified using internal IDs in many places including:

All methods automatically convert between the string version of an ID ("DEP") and the internal integer symbols (DEP). The internal IDs can be imported from spacy.attrs or retrieved from the StringStore. A map from string attribute names to internal attribute IDs is stored in spacy.attrs.IDS.

The corresponding Token object attributes can be accessed using the same names in lowercase, e.g. token.orth or token.length. For attributes that represent string values, the internal integer ID is accessed as Token.attr, e.g. token.dep, while the string value can be retrieved by appending _ as in token.dep_.
