Wikipedia is a multilingual free online encyclopedia written and maintained by a community of volunteers, known as Wikipedians, through open collaboration and using a wiki-based editing system called MediaWiki. Wikipedia is the largest and most-read reference work in history.

This notebook shows how to load wiki pages from into the Document format that we use downstream.


First, you need to install wikipedia python package.

%pip install --upgrade --quiet  wikipedia


WikipediaLoader has these arguments: - query: free text which used to find documents in Wikipedia - optional lang: default=β€œen”. Use it to search in a specific language part of Wikipedia - optional load_max_docs: default=100. Use it to limit number of downloaded documents. It takes time to download all 100 documents, so use a small number for experiments. There is a hard limit of 300 for now. - optional load_all_available_meta: default=False. By default only the most important fields downloaded: Published (date when document was published/last updated), title, Summary. If True, other fields also downloaded.

from langchain_community.document_loaders import WikipediaLoader
docs = WikipediaLoader(query="HUNTER X HUNTER", load_max_docs=2).load()
docs[0].metadata  # meta-information of the Document
docs[0].page_content[:400]  # a content of the Document
