Getting data from the Scopus API

| categories: scopus, python | tags: | View Comments

I have been exploring the Scopus API (http://dev.elsevier.com/index.html ) lately. This is a RESTful API that allows you to retrieve data about publications via http requests, i.e. from a script. This service is not free; you need to be at an institution that has a Scopus license.

Scopus is very good at finding your papers, and associating them with a Scopus ID. You don't have to do anything to get one, they make it. I have a Scopus ID (http://www.scopus.com/authid/detail.url?origin=AuthorProfile&authorId=7004212771 ) that has all this data via the web, but I wanted to get this data in a tabular form I could use and analyze. Sure you can download a CSV file from that page and analyze that, but I want to script it. I am just like that ;) To use the API, you need to get an API key (http://www.developers.elsevier.com/action/devprojects ). I still cannot figure out if this key is "private" so I am not going to share mine here. I have stored it in a python file called my_scopus.py, and I will import it in these examples.

The code below is "wide", so apologies in advance that some of it will run out of the usual area it belongs.

1 About me from Scopus

There is an author API that provides a metrics view of a Scopus ID. Here this shows there are about 77 documents for me, cited about 3028 times. Why do I say "about"? Apparently there are two different databases that Scopus uses, one for the web, and one for this API, and they do not return the same data. It is close, but not the same. The API database includes thing that are published after 1995, and it may not be updated as quickly as the web database. For example the web page reports 79 documents and 3143 citations. In the next sections we will use the search API, which returns the same information as what is on the web. Here we just illustrate how to setup an http request in Python. I like json output, so we ask for it.

import requests
import json
from my_scopus import MY_API_KEY

resp = requests.get("http://api.elsevier.com/content/author?author_id=7004212771&view=metrics",
                    headers={'Accept':'application/json',
                             'X-ELS-APIKey': MY_API_KEY})

print json.dumps(resp.json(),
                 sort_keys=True,
                 indent=4, separators=(',', ': '))
{
    "author-retrieval-response": [
        {
            "@_fa": "true",
            "@status": "found",
            "coauthor-count": "90",
            "coredata": {
                "citation-count": "3028",
                "cited-by-count": "2369",
                "dc:identifier": "AUTHOR_ID:7004212771",
                "document-count": "77",
                "prism:url": "http://api.elsevier.com/content/author/author_id/7004212771"
            },
            "h-index": "18"
        }
    ]
}

2 Get my documents from Scopus

To find my documents, we will use the Search API, http://api.elsevier.com/documentation/SCOPUSSearchAPI.wadl . We specify a Scopus ID, and to limit the quantity of data that comes back we specify that we want the dc:identifier field, which corresponds to the scopus id for each document. We will use that in the next section to get info for each document.

import requests
import json
from my_scopus import MY_API_KEY
resp = requests.get("http://api.elsevier.com/content/search/scopus?query=AU-ID(7004212771)&field=dc:identifier&count=100",
                    headers={'Accept':'application/json',
                             'X-ELS-APIKey': MY_API_KEY})

results = resp.json()

return [[str(r['dc:identifier'])] for r in results['search-results']["entry"]]

3 Retrieve info for a document

Here, we work out how to retrieve data for a document. We use the Abstract API (http://api.elsevier.com/documentation/AbstractRetrievalAPI.wadl ). We again use a field to limit the amount of data. Here is an example that works for an article. Scopus also lists books and conferences so, we will see how that works later. Note the unicode stuff. I was getting some errors about non-ascii characters causing the json file not to read, and then issues in constructing the string. This was only a problem for some entries.

import requests
import json
from my_scopus import MY_API_KEY

def get_scopus_info(SCOPUS_ID):
    url = ("http://api.elsevier.com/content/abstract/scopus_id/"
          + SCOPUS_ID
          + "?field=authors,title,publicationName,volume,issueIdentifier,"
          + "prism:pageRange,coverDate,article-number,doi,citedby-count,prism:aggregationType")
    resp = requests.get(url,
                    headers={'Accept':'application/json',
                             'X-ELS-APIKey': MY_API_KEY})
    results = json.loads(resp.text.encode('utf-8'))

    fstring = '{authors}, {title}, {journal}, {volume}, {articlenum}, ({date}). {doi} (cited {cites} times).\n'
    return fstring.format(authors=', '.join([au['ce:indexed-name'] for au in results['abstracts-retrieval-response']['authors']['author']]),
                          title=results['abstracts-retrieval-response']['coredata']['dc:title'].encode('utf-8'),
                          journal=results['abstracts-retrieval-response']['coredata']['prism:publicationName'].encode('utf-8'),
                          volume=results['abstracts-retrieval-response']['coredata']['prism:volume'].encode('utf-8'),
                          articlenum=(results['abstracts-retrieval-response']['coredata'].get('prism:pageRange') or
                              results['abstracts-retrieval-response']['coredata'].get('article-number')).encode('utf-8'),
                          date=results['abstracts-retrieval-response']['coredata']['prism:coverDate'].encode('utf-8'),
                          doi='doi:' + results['abstracts-retrieval-response']['coredata']['prism:doi'].encode('utf-8'),
                          cites=int(results['abstracts-retrieval-response']['coredata']['citedby-count'].encode('utf-8')))



print get_scopus_info('SCOPUS_ID:0037368024')
Kitchin J.R., Barteau M.A., Chen J.G., A comparison of gold and molybdenum nanoparticles on TiO2(1 1 0) 1 × 2 reconstructed single crystal surfaces, Surface Science, 526, 323-331, (2003-03-01). doi:10.1016/S0039-6028(02)02679-1 (cited 27 times).

4 Get information for all documents

We will use the data we previously got in the long list of Scopus IDs. A few subtle points here are that I made that a nested list so it would print as a column, and so we will have to index each entry to get the scopus id. Also, it seems that some entries generate json that cannot be parsed by python, so we wrap this in a try block and skip those entries. We need to check for the entry being a Journal article, to avoid errors with our format string. We also need to accomodate journals that do not have page ranges, but have artice numbers instead. Finally, we will format each entry so there is some html code for it.

import requests
import json
import textwrap
from my_scopus import MY_API_KEY

def get_scopus_info(SCOPUS_ID):
    url = ("http://api.elsevier.com/content/abstract/scopus_id/"
          + SCOPUS_ID
          + "?field=authors,title,publicationName,volume,issueIdentifier,"
          + "prism:pageRange,coverDate,article-number,doi,citedby-count,prism:aggregationType")
    resp = requests.get(url,
                    headers={'Accept':'application/json',
                             'X-ELS-APIKey': MY_API_KEY})

    return json.loads(resp.text.encode('utf-8'))


i = 0
for sid in scopus_ids:
    # some entries seem to have json parse errors, so we catch those
    try:
        results = get_scopus_info(sid[0])  # index 0 because the input data is a 2d array
        if results['abstracts-retrieval-response']['coredata']['prism:aggregationType'] == 'Journal':
            i += 1
            fstring = '{authors}, {title}, {journal}, {volume}, {articlenum}, ({date}). <a href="http://dx.doi.org/{doi}">{doi}</a> (cited {cites} times)\n\n'

5 Summary thoughts

I see a lot of potential here for analytics on publications, generation of bibliography files, etc… Instead of retrieving this data every time, it would make much more sense to cache it, e.g. writing each result to a file that could then be used locally, and much faster. The downside of that is, the citations would not be updated in those files. The upside is, you could fix the titles so they are properly marked up. I do not know what the issues with some of the json files was. Some of them were unicode issues. Some other day I will try to track down the other ones.

The entries could be made a lot more functional than this. Each author could be turned into a link back to the scopus author page, for example, the title could be linked to the scopus abstract page, etc… The citations could be a button that automatically updates (like the one in this post ). That is another exercise, for another day!
