Mine implicit features using a generative feature language model.

Project description

GFLM: mine implicit features using a generative feature language model

Description

This package implements a Generative Feature Language Models for Mining Implicit Features.

Given the following input:

  • a text dataset
  • a set of predefined features

Compute the following:

  • mapping of explicit and implicit features on the data
  • using both gflm_word and gflm_section algorithms

Install

pip install feature_mining

Sample Usage

Usage:
    from feature_mining import FeatureMining
    fm = FeatureMining()
    fm.load_ipod(full_set=False)
    fm.fit()
    fm.predict()

Results:
    - prediction using 'section': fm.gflm.gflm_section
    - prediction using 'word': fm.gflm.gflm_word

Display result:
    fm.section_features()
    print(fm.gflm_section_result.sort_values(by=['gflm_section'], ascending=False)[['feature', 'section_text']].head(20))
