Text Splitter for Large Language Model datasets.
To avoid token constraints and improve the accuracy of vector search in the Large Language Model, it is necessary to divide the document. This gem supports splitting the text in the specified manner.
Install the gem and add to the application's Gemfile by executing:
$ bundle add baran
If bundler is not being used to manage dependencies, install the gem by executing:
$ gem install baran
chunk_size
: 1024 (characters)chunk_overlap
: 64 (characters)
Splitting by the specified character.
splitter = Baran::CharacterTextSplitter.new(
chunk_size: 1024,
chunk_overlap: 64,
separator: "\n\n"
)
splitter.chunks(text, metadata: { ... })
# => [{ cursor: 0, text: "...", metadata: { ... } }, ...]
Splitting by the specified characters recursively.
splitter = Baran::RecursiveCharacterTextSplitter.new(
separators: ["\n\n", "\n", " ", ""]

splitter.chunks(text, metadata: { ... })
# => [{ cursor: 0, text: "...", metadata: { ... } }, ...]
