Simplest codes to parse / get data from Science portals.
To get information from science sources like Scopus, WoS, Dissemin etc you need to make request to the API or to parse data directly from the Web-site. I have a possibility to get data from the ~20 such science portals.
Here are the code examples to begin with it. I make it easily without OOP to the fast and clear start. Next you can add patterns, classes structures etc. With this code, you can test a possibility to get data.
