A package providing text segmentation evaluation metrics and utilities
Project description
Text segmentation is the task of splitting up any amount of text into segments by placing boundaries between some atomic unit (e.g., morphemes, words, lines, sentences, paragraphs, sections, etc.). It’s a common pre-processing step in many Natural Language Processing (NLP) tasks.
This package is a collection of metrics and for comparing text segmentations and evaluating automatic text segmenters. Both new (Boundary Similarity, Segmentation Similarity) and traditional (WindowDiff, Pk) are included, as well as inter-coder agreement coefficients and confusion matrices based upon a boundary edit distance.
To see some examples of its usage, read the docs.
Feature Support
Included is a variety of segmentation comparison metrics, including:
Boundary Edit Distance (BED)
Boundary Similarity (B)
BED-based confusion matrices (and precision/recall/F1)
Segmentation Similarity (S)
WindowDiff
Pk
Additionally, B-based inter-coder agreement coefficients for segmentation that are suitable for 2 or more coders are provided, including:
Fleiss’ Pi (i.e., Siegel and Castellan’s K)
Fleiss’ Kappa
Installation
To install SegEval, simply run:
$ pip install segeval
