Techniques that involve semantics and the choosing of words. Anglish: a writing using exclusively words of Germanic origin; Auto-antonym: a word that contains opposite meanings; Autogram: a sentence that provide an inventory of its own characters; Irony; Malapropism: incorrect usage of a word by substituting a similar-sounding word with ...
In natural language processing, a word embedding is a representation of a word. The embedding is used in text analysis.Typically, the representation is a real-valued vector that encodes the meaning of the word in such a way that the words that are closer in the vector space are expected to be similar in meaning. [1]
The reasons for successful word embedding learning in the word2vec framework are poorly understood. Goldberg and Levy point out that the word2vec objective function causes words that occur in similar contexts to have similar embeddings (as measured by cosine similarity) and note that this is in line with J. R. Firth's distributional hypothesis ...
Context-free models such as word2vec or GloVe generate a single word embedding representation for each word in the vocabulary, whereas BERT takes into account the context for each occurrence of a given word. For instance, whereas the vector for "running" will have the same word2vec vector representation for both of its occurrences in the ...
Word2vec is a word embedding technique which learns to represent words through self-supervision over each word and its neighboring words in a sliding window across a large corpus of text. [28] The model has two possible training schemes to produce word vector representations, one generative and one contrastive. [27]
In practice however, BERT's sentence embedding with the [CLS] token achieves poor performance, often worse than simply averaging non-contextual word embeddings. SBERT later achieved superior sentence embedding performance [8] by fine tuning BERT's [CLS] token embeddings through the usage of a siamese neural network architecture on the SNLI dataset.
This type of technique is also called anchorage, found by Roland Barthes: [12] anchoring text to a context that changes the intentional meaning. An example of this would be, the music video, Right Now, by Van Halen. The lyrics of the song Right Now suggest an entirely different meaning than the social empowering messages shown through the music ...
A play within a play occurs in the musical The King and I, where Princess Tuptim and the royal dancers give a performance of Small House of Uncle Thomas (or Uncle Tom's Cabin) to their English guests. The play mirrors Tuptim's situation, as she wishes to run away from slavery to be with her lover, Lun Tha.
