+## haystack_integrations.components.extractors.spacy.named_entity_extractor
+
+### NamedEntityAnnotation
+
+Describes a single NER annotation.
+
+**Parameters:**
+
+- **entity** (<code>str</code>) – Entity label.
+- **start** (<code>int</code>) – Start index of the entity in the document.
+- **end** (<code>int</code>) – End index of the entity in the document.
+- **score** (<code>float | None</code>) – Score calculated by the model.
+
+### SpacyNamedEntityExtractor
+
+Annotates named entities in a collection of documents.
+
+The component can be used with any [spaCy model](https://spacy.io/models) that contains
+an NER component. Annotations are stored as metadata in the documents.
+
+Usage example:
+
+```python
+from haystack import Document
+
+from haystack_integrations.components.extractors.spacy import SpacyNamedEntityExtractor
+
+documents = [
+    Document(content="I'm Merlin, the happy pig!"),
+    Document(content="My name is Clara and I live in Berkeley, California."),
+]
+extractor = SpacyNamedEntityExtractor(model="en_core_web_sm")
+results = extractor.run(documents=documents)["documents"]
+annotations = [SpacyNamedEntityExtractor.get_stored_annotations(doc) for doc in results]
+print(annotations)
+```
+
+#### __init__
+
+```python
+__init__(
+    *,
+    model: str,
+    pipeline_kwargs: dict[str, Any] | None = None,
+    device: ComponentDevice | None = None
+) -> None
+```
+
+Create a Named Entity extractor component.
+
+**Parameters:**
+
+- **model** (<code>str</code>) – Name of the spaCy model or a path to the model on
+  the local disk.
+- **pipeline_kwargs** (<code>dict\[str, Any\] | None</code>) – Keyword arguments passed to the pipeline. The
+  pipeline can override these arguments.
+- **device** (<code>ComponentDevice | None</code>) – The device on which the model is loaded. If `None`,
+  the default device is automatically selected.
+
+**Raises:**
+
+- <code>ValueError</code> – If the device represents multiple devices, which the
+  spaCy backend does not support.
+
+#### warm_up
+
+```python
+warm_up() -> None
+```
+
+Initialize the component.
+
+**Raises:**
+
+- <code>ComponentError</code> – If the component fails to initialize successfully.
+
+#### run
+
+```python
+run(documents: list[Document], batch_size: int = 1) -> dict[str, Any]
+```
+
+Annotate named entities in each document and store the annotations in the document's metadata.
+
+**Parameters:**
+
+- **documents** (<code>list\[Document\]</code>) – Documents to process.
+- **batch_size** (<code>int</code>) – Batch size used for processing the documents.
+
+**Returns:**
+
+- <code>dict\[str, Any\]</code> – Processed documents.
+
+**Raises:**
+
+- <code>ComponentError</code> – If the model fails to process a document.
+
+#### to_dict
+
+```python
+to_dict() -> dict[str, Any]
+```
+
+Serializes the component to a dictionary.
+
+**Returns:**
+
+- <code>dict\[str, Any\]</code> – Dictionary with serialized data.
+
+#### from_dict
+
+```python
+from_dict(data: dict[str, Any]) -> SpacyNamedEntityExtractor
+```
+
+Deserializes the component from a dictionary.
+
+**Parameters:**
+
+- **data** (<code>dict\[str, Any\]</code>) – Dictionary to deserialize from.
+
+**Returns:**
+
+- <code>SpacyNamedEntityExtractor</code> – Deserialized component.
+
+#### initialized
+
+```python
+initialized: bool
+```
+
+Returns if the extractor is ready to annotate text.
+
+#### get_stored_annotations
+
+```python
+get_stored_annotations(
+    document: Document,
+) -> list[NamedEntityAnnotation] | None
+```
+
+Returns the document's named entity annotations stored in its metadata, if any.
+
+**Parameters:**
+
+- **document** (<code>Document</code>) – Document whose annotations are to be fetched.
+
+**Returns:**
+
+- <code>list\[NamedEntityAnnotation\] | None</code> – The stored annotations.
