TextEssence is a tool for comparative text analysis.
Word embeddings capture patterns in how words are used in collections of text. Concept embeddings do the same for knowledge base concepts.
TextEssence lets you examine the differences between different sets of embeddings, to see what they capture about different corpora.
- Train word and concept embeddings on any corpus, no annotations required.
- Compare differences in embedding nearest neighbors between different corpora.
- Visualize changes in the organization of embedding spaces from different corpora.
