Cross-ecosystem categorization: A manual-curation protocol for the categorization of Java Maven libraries along Python PyPI Topics
CoRR(2024)
摘要
Context: Software of different functional categories, such as text processing
vs. networking, has different profiles in terms of metrics like security and
updates. Using popularity to compare e.g. Java vs. Python libraries might give
a skewed perspective, as the categories of the most popular software vary from
one ecosystem to the next. How can one compare libraries datasets across
software ecosystems, when not even the category names are uniform among them?
Objective: We study how to generate a language-agnostic categorisation of
software by functional purpose, that enables cross-ecosystem studies of
libraries datasets. This provides the functional fingerprint information needed
for software metrics comparisons. Method: We designed and implemented a
human-guided protocol to categorise libraries from software ecosystems.
Category names mirror PyPI Topic classifiers, but the protocol is generic and
can be applied to any ecosystem. We demonstrate it by categorising 256
Java/Maven libraries with severe security vulnerabilities. Results: The
protocol allows three or more people to categorise any number of libraries. The
categorisation produced is functional-oriented and language-agnostic. The
Java/Maven dataset demonstration resulted in a majority of Internet-oriented
libraries, coherent with its selection by severe vulnerabilities. To allow
replication and updates, we make the dataset and the protocol individual steps
available as open data. Conclusions: Libraries categorisation by functional
purpose is feasible with our protocol, which produced the fingerprint of a
256-libraries Java dataset. While this was labour intensive, humans excel in
the required inference tasks, so full automation of the process is not
envisioned. However, results can provide the ground truth needed for machine
learning in large-scale cross-ecosystem empirical studies.
