An `EntityLinker` component disambiguates textual mentions (tagged as named
2020-08-06 18:41:26 +03:00
entities) to unique identifiers, grounding the named entities into the "real
2020-08-07 00:20:13 +03:00
world". It requires a `KnowledgeBase`, as well as a function to generate
plausible candidates from that `KnowledgeBase` given a certain textual mention,
and a machine learning model to pick the right candidate, given the local

The default config is defined by the pipeline component factory and describes
how the component should be configured. You can override its settings via the
`config` argument on [`nlp.add_pipe`](/api/language#add_pipe) or in your
[`config.cfg` for training](/usage/training#config). See the
[model architectures](/api/architectures) documentation for details on the
architectures and their arguments and hyperparameters.

| Setting | Description |
| ---------------------------------------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| `labels_discard` | NER labels that will automatically get a "NIL" prediction. Defaults to `[]`. ~~Iterable[str]~~ |
| `n_sents` | The number of neighbouring sentences to take into account. Defaults to 0. ~~int~~ |
| `incl_prior` | Whether or not to include prior probabilities from the KB in the model. Defaults to `True`. ~~bool~~ |
| `incl_context` | Whether or not to include the local context in the model. Defaults to `True`. ~~bool~~ |
| `model` | The [`Model`](https://thinc.ai/docs/api-model) powering the pipeline component. Defaults to [EntityLinker](/api/architectures#EntityLinker). ~~Model~~ |
| `entity_vector_length` | Size of encoding vectors in the KB. Defaults to `64`. ~~int~~ |
| `use_gold_ents` | Whether to copy entities from the gold docs or not. Defaults to `True`. If `False`, entities must be set in the training data or by an annotating component in the pipeline. ~~int~~ |
| `get_candidates` | Function that generates plausible candidates for a given `Span` object. Defaults to [CandidateGenerator](/api/architectures#CandidateGenerator), a function looking up exact, case-dependent aliases in the KB. ~~Callable[[KnowledgeBase, Span], Iterable[Candidate]]~~ |

Create a new pipeline instance. In your application, you would normally use a
shortcut for this and instantiate the component using its string name and
2020-10-12 12:41:27 +03:00
[`nlp.add_pipe`](/api/language#add_pipe).
Upon construction of the entity linker component, an empty knowledge base is
constructed with the provided `entity_vector_length`. If you want to use a
custom knowledge base, you should either call
[`set_kb`](/api/entitylinker#set_kb) or provide a `kb_loader` in the
[`initialize`](/api/entitylinker#initialize) call.

This usually happens under the hood when the `nlp` object is called on a text
and all pipeline components are applied to the `Doc` in order. Both
[`__call__`](/api/entitylinker#call) and [`pipe`](/api/entitylinker#pipe)
delegate to the [`predict`](/api/entitylinker#predict) and

## EntityLinker.pipe {#pipe tag="method"}
Apply the pipe to a stream of documents. This usually happens under the hood
when the `nlp` object is called on a text and all pipeline components are
applied to the `Doc` in order. Both [`__call__`](/api/entitylinker#call) and
[`pipe`](/api/entitylinker#pipe) delegate to the
[`predict`](/api/entitylinker#predict) and
[`set_annotations`](/api/entitylinker#set_annotations) methods.
> #### Example
>
> ```python
> entity_linker = nlp.add_pipe("entity_linker")

## EntityLinker.initialize {#initialize tag="method" new="3"}
2020-09-29 17:59:21 +03:00
Initialize the component for training. `get_examples` should be a function that
returns an iterable of [`Example`](/api/example) objects. **At least one example
should be supplied.** The data examples are used to **initialize the model** of
the component and can either be the full training data or a representative
sample. Initialization includes validating the network,
2020-08-11 21:57:23 +03:00
[inferring missing shapes](https://thinc.ai/docs/usage-models#validation) and
2020-09-29 17:59:21 +03:00
setting up the label scheme based on the data. This method is typically called
by [`Language.initialize`](/api/language#initialize).
2020-10-12 12:41:27 +03:00
Optionally, a `kb_loader` argument may be specified to change the internal
knowledge base. This argument should be a function that takes a `Vocab` instance
and creates the `KnowledgeBase`, ensuring that the strings of the knowledge base
are synced with the current vocab.

## Serialization fields {#serialization-fields}
During serialization, spaCy will export several data fields used to restore
different aspects of the object. If needed, you can exclude them from
serialization by passing in the string names via the `exclude` argument.
> #### Example
>
> ```python
> data = entity_linker.to_disk("/path", exclude=["vocab"])
> ```
| Name | Description |
| ------- | -------------------------------------------------------------- |
| `vocab` | The shared [`Vocab`](/api/vocab). |
| `cfg` | The config file. You usually don't want to exclude this. |
| `model` | The binary model data. You usually don't want to exclude this. |
| `kb` | The knowledge base. You usually don't want to exclude this. |
