⚡ Blazing Fast topic modelling over short texts in Python
- Fast ⚡
- Scalable 💥
- High consistency and coherence 🎯
- High quality topics 🔥
- Easy visualization and inspection 👀
- Full scikit-learn compatibility 🔩
You can now pass random_state to topic models to make your results reproducible.
from tweetopic import DMM
model = DMM(10, random_state=42)Install from PyPI:
pip install tweetopic👩💻 Usage (documentation)
Train your a topic model on a corpus of short texts:
from tweetopic import DMM
from sklearn.feature_extraction.text import CountVectorizer
from sklearn.pipeline import Pipeline
# Creating a vectorizer for extracting document-term matrix from the
# text corpus.
vectorizer = CountVectorizer(min_df=15, max_df=0.1)
# Creating a Dirichlet Multinomial Mixture Model with 30 components
dmm = DMM(n_components=30, n_iterations=100, alpha=0.1, beta=0.1)
# Creating topic pipeline
pipeline = Pipeline([
("vectorizer", vectorizer),
("dmm", dmm),
])You may fit the model with a stream of short texts:
pipeline.fit(texts)To investigate internal structure of topics and their relations to words and indicidual documents we recommend using topicwizard.
Install it from PyPI:
pip install topic-wizardThen visualize your topic model:
import topicwizard
