langchain_text_splitters.spacy.SpacyTextSplitter¶

class langchain_text_splitters.spacy.SpacyTextSplitter(separator: str = '\n\n', pipeline: str = 'en_core_web_sm', max_length: int = 1000000, *, strip_whitespace: bool = True, **kwargs: Any)[source]¶

Splitting text using Spacy package.

Per default, Spacy’s en_core_web_sm model is used and its default max_length is 1000000 (it is the length of maximum character this model takes which can be increased for large files). For a faster, but potentially less accurate splitting, you can use pipeline=’sentencizer’.

Initialize the spacy text splitter.

Methods

__init__([separator, pipeline, max_length, ...])

Initialize the spacy text splitter.

atransform_documents(documents, **kwargs)

Asynchronously transform a list of documents.

create_documents(texts[, metadatas])

Create documents from a list of texts.

from_huggingface_tokenizer(tokenizer, **kwargs)

Text splitter that uses HuggingFace tokenizer to count length.

from_tiktoken_encoder([encoding_name, ...])

Text splitter that uses tiktoken encoder to count length.

split_documents(documents)

Split documents.

split_text(text)

Split incoming text and return chunks.

transform_documents(documents, **kwargs)

Transform sequence of documents by splitting them.

Parameters
  • separator (str) –
