About

A small library for extracting references used in scholarly communication.

Install

.. code-block:: console

$ pip install refextract

Usage

To get structured information from a publication reference:

.. code-block:: python

>>> from refextract import extract_journal_reference
>>> reference = extract_journal_reference('J.Phys.,A39,13445')
>>> print(reference)
{
    'extra_ibids': [],
    'is_ibid': False,
    'misc_txt': u'',
    'page': u'13445',
    'title': u'J. Phys.',
    'type': 'JOURNAL',
    'volume': u'A39',
    'year': '',
}

To extract references from a PDF:

.. code-block:: python

>>> from refextract import extract_references_from_file
>>> references = extract_references_from_file('1503.07589.pdf')
>>> print(references[0])
{
    'author': [u'F. Englert and R. Brout'],
    'doi': [u'doi:10.1103/PhysRevLett.13.321'],
    'journal_page': [u'321'],
    'journal_reference': [u'Phys. Rev. Lett. 13 (1964) 321'],
    'journal_title': [u'Phys. Rev. Lett.'],
    'journal_volume': [u'13'],
    'journal_year': [u'1964'],
    'linemarker': [u'1'],
    'raw_ref': [u'[1] F. Englert and R. Brout, \u201cBroken symmetry and the mass of gauge vector mesons\u201d, Phys. Rev. Lett. 13 (1964) 321, doi:10.1103/PhysRevLett.13.321.'],
    'texkey': [u'Englert:1964et'],
    'year': [u'1964'],
}

To extract directly from a URL:

.. code-block:: python

>>> from refextract import extract_references_from_url
>>> references = extract_references_from_url('https://arxiv.org/pdf/1503.07589.pdf')
>>> print(references[0])
{
    'author': [u'F. Englert and R. Brout'],
    'doi': [u'doi:10.1103/PhysRevLett.13.321'],
    'journal_page': [u'321'],
    'journal_reference': [u'Phys. Rev. Lett. 13 (1964) 321'],
    'journal_title': [u'Phys. Rev. Lett.'],
    'journal_volume': [u'13'],
    'journal_year': [u'1964'],
    'linemarker': [u'1'],
    'raw_ref': [u'[1] F. Englert and R. Brout, \u201cBroken symmetry and the mass of gauge vector mesons\u201d, Phys. Rev. Lett. 13 (1964) 321, doi:10.1103/PhysRevLett.13.321.'],
    'texkey': [u'Englert:1964et'],
    'year': [u'1964'],
}
