Bases: airflow.models.BaseOperator

Finds named entities in the text along with entity types, salience, mentions for each entity, and other properties.

Parameters

  • document (Union[dict, google.cloud.language_v1.types.Document]) -- Input document. If a dict is provided, it must be of the same form as the protobuf message Document

  • encoding_type (Optional[google.cloud.language_v1.enums.EncodingType]) -- The encoding type used by the API to calculate offsets.

  • retry (Optional[google.api_core.retry.Retry]) -- A retry object used to retry requests. If None is specified, requests will not be retried.

  • timeout (Optional[float]) -- The amount of time, in seconds, to wait for the request to complete. Note that if retry is specified, the timeout applies to each individual attempt.

  • metadata (MetaData) -- Additional metadata that is provided to the method.

  • gcp_conn_id (str) -- The connection ID to use connecting to Google Cloud.

  • impersonation_chain (Optional[Union[str, Sequence[str]]]) -- Optional service account to impersonate using short-term credentials, or chained list of accounts required to get the access_token of the last account in the list, which will be impersonated in the request. If set as a string, the account must grant the originating account the Service Account Token Creator IAM role. If set as a sequence, the identities from the list must grant Service Account Token Creator IAM role to the directly preceding identity, with first account from the list granting this role to the originating account (templated).

template_fields :Sequence[str] = ['document', 'gcp_conn_id', 'impersonation_chain'][source]
execute(self, context)[source]

This is the main method to derive when creating an operator. Context is the same dictionary used as when rendering jinja templates.

Refer to get_template_context for more context.

Bases: airflow.models.BaseOperator

Finds entities, similar to AnalyzeEntities in the text and analyzes sentiment associated with each entity and its mentions.
