LitStudy

LitStudy is a Python package that enables analysis of scientific literature from the comfort of a Jupyter notebook. It provides the ability to select scientific publications and study their metadata through the use of visualizations, network analysis, and natural language processing.

In essence, this package offers five main features:

• Extract metadata from scientific documents sourced from various locations. The data is presented in a standardized interface, allowing for the combination of data from different sources.
• Filter, select, deduplicate, and annotate collections of documents.
• Compute and plot general statistics for document sets, such as statistics on authors, venues, and publication years.
• Generate and plot various bibliographic networks as interactive visualizations.
• Topic discovery using natural language processing (NLP) allows for the automatic discovery of popular topics.

Requirements

The package has been tested for Python 3.7. Required packages are available in requirements.txt.

litstudy supports several data sources. Some of these sources (such as semantic Scholar, CrossRef, and arXiv) are openly available. However to access the Scopus API, you (or your institute) requires a Scopus subscription and you need to request an Elsevier Developer API key (see Elsevier Developers). For more information, see the guide by pybliometrics.
