Practical overview
When it fits
Use Shifterator when a pairwise text comparison needs an interpretable account of which words drive the difference, rather than only an aggregate result.
Who it is for
- Researchers comparing text collections or documents
- Analysts studying word use, sentiment, entropy or divergence
Documented uses
- Visualize word-level contributions behind sentiment differences.
- Inspect terms contributing to changes in text entropy.
- Explain word-level contributions to divergence between two texts.
Requirements & limits
The project provides a pip installation command for the Python package and specifies an Apache-2.0 license. Its README directs users to install from GitHub rather than the outdated PyPI 0.3.0 release.
- The documented output is a vertical bar-chart format called a word-shift graph.
- The maintained installation route identified by the README is GitHub.
- The repository contains documentation in its docs/ folder; the older Read the Docs site may not reflect the current version.
Check current requirements in the official documentation. Source-based guidance does not mean OpenViST has run or independently tested this project.
