Summary

GROBID (or Grobid, but not GroBid nor GroBiD) means GeneRation Of BIbliographic Data.

GROBID is a machine learning library for extracting, parsing and re-structuring raw documents such as PDF into structured XML/TEI encoded documents with a particular focus on technical and scientific publications. First developments started in 2008 as a hobby. In 2011 the tool has been made available in open source. Work on GROBID has been steady as a side project since the beginning and is expected to continue as such.

The following functionalities are available:

  • Header extraction and parsing from article in PDF format. The extraction here covers the usual bibliographical information (e.g. title, abstract, authors, affiliations, keywords, etc.).
  • References extraction and parsing from articles in PDF format, around .87 f-score against on an independent PubMed Central set of 1943 PDF containing 90,125 references. All the usual publication metadata are covered (including DOI, PMID, etc.).
  • Citation contexts recognition and resolution to the full bibliographical references of the article. The accuracy of citation contexts resolution is above .76 f-score (which corresponds to both the correct identification of the citation callout and its correct association with a full bibliographical reference).
  • Parsing of references in isolation (around .90 f-score at instance-level, .95 f-score at field level).
  • Parsing of names (e.g. person title, forenames, middlename, etc.), in particular author names in header, and author names in references (two distinct models).
  • Parsing of affiliation and address blocks.
  • Parsing of dates, ISO normalized day, month, year.
  • Full text extraction and structuring from PDF articles, including a model for the overall document segmentation and models for the structuring of the text body (paragraph, section titles, reference callout, figure, table, etc.).
  • Consolidation/resolution of the extracted bibliographical references using the biblio-glutton service or the CrossRef REST API. In both cases, DOI resolution performance is higher than 0.95 f-score from PDF extraction.
  • Extraction and parsing of patent and non-patent references in patent publications.
  • PDF coordinates for extracted information, allowing to create "augmented" interactive PDF.

In a complete PDF processing, GROBID manages 55 final labels used to build relatively fine-grained structures, from traditional publication metadata (title, author first/last/middlenames, affiliation types, detailed address, journal, volume, issue, pages, doi, pmid, etc.) to full text structures (section title, paragraph, reference markers, head/foot notes, figure headers, etc.).

GROBID includes a comprehensive web service API, batch processing, a JAVA API, a Docker image, a generic evaluation framework (precision, recall, etc., n-fold cross-evaluation) and the semi-automatic generation of training data.

GROBID can be considered as production ready. Deployments in production includes ResearchGate, HAL Research Archive, INIST-CNRS, CERN (Invenio), scite.ai, and many more. The tool is designed for high scalability in order to address the full scientific literature corpus.

GROBID should run properly "out of the box" on Linux (64 bits) and macOS. We cannot ensure currently support for Windows as we did before (help welcome!).

GROBID uses optionnally Deep Learning models relying on the DeLFT library, a task-agnostic Deep Learning framework for sequence labelling and text classification. The tool can run with feature engineered CRF (default), Deep Learning architectures (with or without layout feature channels) or any mixtures of CRF and DL to balance scalability and accuracy.

For more information on how the tool works, on its key features and benchmarking, visit the GROBID documentation.

Demo

For testing purposes, a public GROBID demo server is available at the following address: https://grobid.science-miner.com

The Web services are documented here.

Warning: Some quota and query limitation apply to the demo server! Please be courteous and do not overload the demo server.

Clients

For helping to exploit GROBID service at scale, we provide clients written in Python, Java, node.js using the web services for parallel batch processing:

All these clients will take advantage of the multi-threading for scaling large set of PDF processing. As a consequence, they will be much more efficient than the batch command lines (which use only one thread) and should be prefered.

We have been able recently to run the complete fulltext processing at around 10.6 PDF per second (around 915,000 PDF per day, around 20M pages per day) with the node.js client listed above during one week on one 16 CPU machine (16 threads, 32GB RAM, no SDD, articles from mainstream publishers), see here (11.3M PDF were processed in 6 days by 2 servers without interruption).

In addition, a Java example project is available to illustrate how to use GROBID as a Java library: https://github.com/kermitt2/grobid-example. The example project is using GROBID Java API for extracting header metadata and citations from a PDF and output the results in BibTeX format.

Finally, the following python utilities can be used to create structured full text corpora of scientific articles simply by indicating a list of strong identifiers like DOI or PMID, performing the identification of online Open Access PDF, the harvesting, the metadata agreegation and the Grobid processing in one step at scale: article-dataset-builder

GROBID Modules

A series of additional modules have been developed for performing structure aware text mining directly on scholar PDF, reusing GROBID's PDF processing and sequence labelling weaponery:

  • grobid-ner: named entity recognition
  • grobid-quantities: recognition and normalization of physical quantities/measurements
  • software-mention: recognition of software mentions and attributes in scientific literature
  • grobid-astro: recognition of astronomical entities in scientific papers
  • grobid-bio: a bio-entity tagger using BioNLP/NLPBA 2004 dataset
  • grobid-dictionaries: structuring dictionaries in raw PDF format
  • grobid-superconductors: recognition of superconductor material and properties in scientific literature
  • entity-fishing, a tool for extracting Wikidata entities from text and document, can also use Grobid to pre-process scientific articles in PDF, leading to more precise and relevant entity extraction and the capacity to annotate the PDF with interative layout.
  • dataseer-ml: identification of sections and sentences introducing a dataset in a scientific article, and classification of the type of this dataset.

  • Could the java documentation and the process of embedding grobid into Java project be updated?

    Could the java documentation and the process of embedding grobid into Java project be updated?

    Following the instructions on the grobid site, I cannot embed grobid into my JAVA project due to poor instructions regarding Gradle and Maven. Also, I do not know how to use the APIs because the Java documentation has different parameters for the methods. Specifically, fullTextToTei take in different arguments than what is shown in the Java docs.

    Add additional pattern to match the mathematical dashes (hypens

    Issue with this character is that the FormatNumber class fails to parse a negative number with such symbol.

    e.g.:

    Grobid "processFulltextDocument" skipping some references

    in processing references of some reports (by using processFulltextDocument) I noticed that Grobid seems to skip some pages

    for example, when the following file is processed , the references extracted seems to start after the third page (it jumps to references starting with the letter B )

    FAO_report_biodiversityforFoodAgriculture.pdf

    see results xref_raw_test.txt

    it does also not help if one adds few pages in the front :
