"\n",
"GROBID is a machine learning library for extracting, parsing, and re-structuring raw documents.\n",
"\n",
"It is designed and expected to be used to parse academic papers, where it works particularly well. Note: if the articles supplied to Grobid are large documents (e.g. dissertations) exceeding a certain number of elements, they might not be processed. \n",
"\n",
"This loader uses Grobid to parse PDFs into `Documents` that retain metadata associated with the section of text.\n",
"\n",
"---\n",
"The best approach is to install Grobid via docker, see https://grobid.readthedocs.io/en/latest/Grobid-docker/. \n",
"\n",
"(Note: additional instructions can be found [here](https://python.langchain.com/docs/docs/integrations/providers/grobid.mdx).)\n",
"\n",
"Once grobid is up-and-running you can interact as described below. \n"
