Features

• Extract keywords with semantic similarity scoring
• Boost keyword matches using entities (dates, times, places, etc.)
• Supports custom IDF weighting for better relevance
• Easy-to-use API for integration into NLP pipelines

---

Installation

Install from PyPI:

pip install keywordx

Or install from source:

git clone https://github.com/keikurono7/keywordx.git
cd keywordx
pip install -e .

Quick Start

Here is a quick example to get you started:

from keywordx import KeywordExtractor

ke = KeywordExtractor()
text = "Tomorrow I have a work meeting at 5pm in Bangalore."
keywords = ["meeting", "time", "place", "date"]

result = ke.extract(text, keywords)
print(result)

Example Output

The result will include extracted entities and semantic matches with scores:

{
  "entities": [
    {"span": [0, 8], "text": "Tomorrow", "type": "DATE"},
    {"span": [34, 37], "text": "5pm", "type": "TIME"},
    {"span": [41, 50], "text": "Bangalore", "type": "GPE"}
  ],
  "semantic_matches": [
    {"keyword": "meeting", "match": "meeting", "score": 0.99},
    {"keyword": "time", "match": "5pm", "score": 1.0},
    {"keyword": "place", "match": "Bangalore", "score": 1.0},
    {"keyword": "date", "match": "Tomorrow", "score": 1.0}
  ]
}
