ADSutils

This is a module with various ADS specific utilities

Installing

Clone the repo to a local directory

git clone https://github.com/adsabs/adsutils adsutils 

Go into the newly created directory and create a virtual environment

virtualenv --no-site-packages -ppython2.7 venv

and start it

source venv/bin/activate

Update pip like

pip install -U pip

and then install the required software

pip install -r requirements.txt

Test if things are working:

python test/nosetests.py

Utility to create bibcodes

Import the relevant module:

from adsutils import make_bibcode

and provide the necessary metadata:

data = {"year":"2006",
        "bibstem":'PhRvL',
        "volume":"96",
        "page":"295701",
        "author":'Grünwald, Michael',
        }

and then call

bibcode = make_bibcode(data)

and a bibcode will get generated. You will have to determine the correct journal abbreviation (bibstem). The journal abbreviations are available here: http://adsabs.harvard.edu/abs_doc/journals2.html

Utility to resolve reference strings

Import the relevant module:

from adsutils import resolve_references

You can provide reference data in various formats:

• A single reference string
• A newline-separated set of reference strings
• A (Python) list of reference strings

Examples: A case with just one reference string:

refdata = 'Hermsen, W., et. al. 1992, IAU Circ. No. 5541'
result = resolve_references(refdata)

in which case the result (always a list of dictionaries) will look like

[{'refstring': u'Hermsen, W., et. al. 1992, IAU Circ. No. 5541', 
 'confidence': 'Success', 
 'bibcode': u'1992IAUC.5541....1H'
}]

Multiple reference strings work as follows:

refdata = ['J. B. Gupta, and J. H. Hamilton, Phys. Rev. C 16, 427 (1977)', 'Pollock, J. T. 1982, Ph. D. Thesis, University of Florida']
result = resolve_references(refdata)

in which case the result (always a list of dictionaries) will look like

[{'refstring': u'J. B. Gupta, and J. H. Hamilton, Phys. Rev. C 16, 427 (1977)', 
  'confidence': 'Success', 
  'bibcode': u'1977PhRvC..16..427G'},  
 {'refstring': u'Pollock, J. T. 1982, Ph. D. Thesis, University of Florida', 
  'confidence': 'Success', 
  'bibcode': u'1982PhDT.........1P'}]

Possible outcome

The resolver can return three classes of 'confidence' levels:

• Success
• Failed
• Not verified

The only class that needs some explanation is the last one; it is quite possible that the metadata contains enough information to guess a bibcode. The year could be off by 1 (which can also apply to the page or volume number) or a journal was abbreviated in a non-standard way. It is also possible that all the metadata is correct, but the record is not in the ADS database. Even though a bibcode is returned, you cannot assume it is correct. These Not verified cases need further inspection.

Utility to get ADS journal abbreviation from publication name

An essential part of the ADS publication identifier (bibcode) is the publication abbreviation (bibstem). This utility takes a string representing the publication name and attempts to match it to an ADS abbreviation. It returns a list of candidates and associated scores.

Import the relevant module:

from adsutils import get_pub_abbreviation

The bibstem candidates are then found as follows:

pubstring = 'American Astronautical Society Meeting'
result = get_pub_abbreviation(pubstring)

which returns a list of tuples with candidates and their associated scores (sorted by score, descending):

[(1.0, 'aans.meet'), (0.98545706272125244, 'AAS......'), (0.95637118816375732, 'aans.symp'), (0.93698060512542725, 'AAS......'), (0.91897505521774292, 'acs..meet')]

You can specify that you are only interested in exact matches in the following way:

pubstring = 'Astrophysical Journal'
result = get_pub_abbreviation(pubstring, exact=True)

which would result in

[(1, 'ApJ......')]

while

pubstring = 'Astrophysical Journ'
result = get_pub_abbreviation(pubstring, exact=True)

would result in

[]
