About
Top2Vec is an open-source Python library designed for advanced topic modeling and semantic search. It automatically detects topics within text data and generates jointly embedded topic, document, and word vectors. The library offers a 'classic' version for general topic modeling and a newer 'contextual' version that leverages contextual token embeddings to identify multiple topics per document and even detect topic segments within documents. This contextual approach provides a more nuanced understanding of complex texts. Key features include automatic topic number detection, hierarchical topic generation, keyword-based topic search, and document search by topic or keywords. Top2Vec eliminates the need for stop word lists, stemming, or lemmatization, and works effectively on short texts. It also supports various embedding models like Doc2Vec, Universal Sentence Encoder, and BERT Sentence Transformer for flexible deployment.
