How is WordPiece tokenization helpful to effectively deal with rare words problem in NLP?

你。 提交于 2020-07-04 06:58:09
问题 I have seen that NLP models such as BERT utilize WordPiece for tokenization. In WordPiece, we split the tokens like playing to play and ##ing . It is mentioned that it covers a wider spectrum of Out-Of-Vocabulary (OOV) words. Can someone please help me explain how WordPiece tokenization is actually done, and how it handles effectively helps to rare/OOV words? 回答1: WordPiece and BPE are two similar and commonly used techniques to segment words into subword-level in NLP tasks. In both cases,

In Spacy NLP, how extract the agent, action, and patient — as well as cause/effect relations?

倖福魔咒の 提交于 2020-06-29 05:04:14
问题 I would like to use Space to extract word relation information in the form of "agent, action, and patient." For example, "Autonomous cars shift insurance liability toward manufacturers" -> ("autonomous cars", "shift", "liability") or ("autonomous cars", "shift", "liability towards manufacturers"). In other words, "who did what to whom" and "what applied the action to something else." I don't know much about my input data, so I can't make many assumptions. I also want to extract logical

问题 I am trying to analyze a series of sentences by identifying the most common adverb-adjective-noun strings.

In this case, I would like to omit common word types like personal pronouns, articles, prepositions and even verbs. Ideally, the results should produce: Most common nouns Most common adjectives Most common adverbs Most common

Classification accuracy is too low (Word2Vec)

问题 i'm working on an Multi-Label Emotion Classification problem to be solved by word2vec. this is my code that i've learned from a couple of tutorials. now the accuracy is very low. about 0.02 which is telling me something is wrong in my code. but i cannot find it. i tried this code for TF-IDF and BOW (obviously except word2vec part) and i got much better accuracy scores such as 0.28, but it seems this one is somehow wrong: np.set_printoptions(threshold=sys.maxsize) wv = gensim.models
