ℹ️ Scopus quickly finds relevant and authoritative research, identifies experts and provides access to reliable data, metrics and analytical tools. Be confident in progressing research, teaching or research direction and priorities — all from one database and with one subscription.

SCOPUS API allows the users to query its database for all the articles based on a specified keyword(s).
A user needs to create an account on SCOPUS using your university or personal account and generate the SCOPUS key.
The API specification can be seen at this link. Using this API, It is possible to retrieve title,authors, affiliation, DOI, etc of the scientific articles. Further, depending on the access level of the article and authorized API, the article's abstract-text can also be retrieved.

Semantic Scholar also provides an API to retrieve the article's meta-data. It is possible to obtain abstracts by specifying the DOI of the article. Abstracts for all SCOPUS database articles are not available from Semantic Scholar database.

1. Create a virtual environment to install all packages in and activate the environment:

   # create an environment called scopuscaller in this project
   python3 -m venv ~/.scopuscaller
   # activate the environment
   source ~/.scopuscaller/bin/activate

2. Install the package

   pip install scopus-caller

1. If you haven't created an account on SCOPUS yet, got to SCOPUS and create a private account or one via your university.
2. After being logged in, create a new API key here, name the label to your likings and leave the website input field empty (it is not important).
   Carefully read and understand the "API SERVICE AGREEMENT" and "Text and Data Mining (TDM) Provisions", before using the API and the retrieved data. These will be presented to the user while generating the API.
3. Copy you API key and store it in a text file.

Import the library and paste the API key. Then run the following code in Python3 terminal or Jupyter notebook.

# import the module
import scopuscaller as sc

# paste the api here
api_key = ""

Parameters of function get_titles.py:

Parameters:

• api_key (str): Your Elsevier API key for authentication.
• keywords (list of str): Keywords to search for in article titles and abstracts.
• year (int, optional): The cut-off year, upto which articles which be retrieved. Default is 2023.

Example:

The following command will search for articles with the search terms transportation, road safety and transfer learning published before 2023 (inclusive).

# Obtain the articles
df = sc.get_titles(api_key, ["transportation", "road safety", "transfer learning"], 2023)

# Obtain the abstracts of the above articles. For abstracts, you need to specify the output of previous step as input and then run the following

df = sc.get_abstracts(df)

If you plan to use abstracts for your work, please attribute this GitHub repository:
