Sense2vec with spaCy and Gensim
If you were doing text analytics in 2015, you were probably using word2vec. Sense2vec (Trask et. al, 2015) is a new twist on word2vec that lets you learn more interesting, detailed and context-sensitive word vectors. This post motivates the idea, explains our implementation, and comes with an interactive demo that we’ve found surprisingly addictive. Polysemy: the problem with word2vec When humans
Gensim: topic modelling for humans
class gensim.models.doc2vec.Doc2Vec(documents=None, corpus_file=None, vector_size=100, dm_mean=None, dm=1, dbow_words=0, dm_concat=0, dm_tag_count=1, dv=None, dv_mapfile=None, comment=None, trim_rule=None, callbacks=(), window=5, epochs=10, shrink_windows=True, **kwargs)¶ Bases: Word2Vec Class for training, using and evaluating neural networks described in Distributed Representations of Sentences
Gensim: topic modelling for humans
✔ Train large-scale semantic NLP models ✔ Represent text as semantic vectors ✔ Find semantically related documents from gensim import corpora, models, similarities, downloader # Stream a training corpus directly from S3. corpus = corpora.MmCorpus("s3://path/to/corpus") # Train Latent Semantic Indexing with 200D vectors. lsi = models.LsiModel(corpus, num_topics=200) # Convert another corpus t
