- gibrown 11y agoInteresting. This basically uses the background word2vec data for the entire Web to provide more information and help with things like disambiguation, synonyms, etc? Am I understanding that correctly? Maybe nit-picky thought, but its not clear to me that the TF-IDF part is what's doing a lot of extra lifting there. Do you know of any good evaluations between using vector space data and other methods for summarization?
- meeper16 11y agoWord2Vec was a fork or based on a more exhuastive vector space approach here https://www.kaggle.com/c/word2vec-nlp-tutorial/forums/t/12349/word2vec-is-based-on-an-approach-from-lawrence-berkeley-national-lab https://www.kaggle.com/c/word2vec-nlp-tutorial/forums/t/1234... I've compared the summarization to others like OTS http://libots.sourceforge.net/ http://libots.sourceforge.net/ which I believe strictly relies on TF-IDF and it seems better and allows for context to control the summarization. Other similar approaches might be based on Latent Semantic Analysis, Latent Semantic Indexing or LDA.
