WordSegment

1.3.1 verified Mon Apr 27 auth: no python maintenance

English word segmentation library that segments concatenated text into separate words. Version 1.3.1 released October 2019; no active development since then. Designed for segmenting hashtags, URLs, or other concatenated phrases.

pip install wordsegment

Common errors

error ImportError: No module named 'wordsegment' ↓

cause The library is not installed or the environment is wrong.

fix

Run 'pip install wordsegment' in the correct Python environment.

error TypeError: segment() missing 1 required positional argument: 'text' ↓

cause Calling segment without arguments or passing keyword incorrectly.

fix

Use segment('yourtext') with a single string argument.

Warnings

gotcha The library uses a unigram model that may not handle proper nouns or domain-specific terms well. It can produce unexpected segmentations for text with numbers or mixed case. ↓

fix Preprocess input to lowercase or clean punctuation. Consider adding custom words to the model.

deprecated This library is no longer actively maintained. Python 2 support may have issues; Python 3 is recommended. ↓

fix Consider using an alternative like 'wordninja' or a more modern NLP library.

gotcha The 'segment' function expects a single string without spaces. Passing a string with spaces will still segment but may produce incorrect results. ↓

fix Remove spaces or punctuation from input before passing to segment.

Imports

segment
```
from wordsegment import segment

Correct import path.

Quickstart
