The original papers describe CBOW and Skip-Gram objectives and evaluate the resulting vectors on syntactic and semantic relationships.
The original Word2Vec papers present CBOW and continuous Skip-Gram architectures for learning distributed word representations. CBOW uses context words to predict a target; Skip-Gram uses a target to predict surrounding context words. The later paper describes negative sampling, subsampling of frequent words, and phrase detection. The learned vectors are useful representations evaluated on specified similarity and relationship tasks; they are not context-sensitive and the papers do not establish particular commercial deployments. The learned input weight matrix supplies the word vectors used after training. The later paper reports subsampling frequent words as a way to speed training and obtain more regular representations. Mikolov and colleagues at Google introduced the architecture papers in 2013. Their vector-analogy example includes king − man + woman ≈ queen; this illustrates a reported geometric relationship, not a guarantee for every vocabulary.
Paper concept: CBOW predicts a center word from its surrounding context.
Paper concept: Skip-Gram predicts context words from a center word.
Paper method: negative sampling replaces a full-vocabulary softmax objective with sampled binary prediction.
Illustrative use: compare vectors for related words in a corpus, while checking the corpus and evaluation task.
For a current application, compare static vectors with contextual encoders on the target data and task. Report corpus, preprocessing, vocabulary coverage, and metric. The cited papers establish model designs and benchmark results, not adoption rates or present-day deployment patterns.

Word2Vec is a family of shallow neural models that learns word vectors from local word contexts. The original papers describe CBOW and Skip-Gram objectives and evaluate the resulting vectors on syntactic and semantic relationships.
Skip-Gram mengambil satu perkataan tengah dan cuba meramalkan setiap perkataan konteks sekelilingnya, bertentangan dengan CBOW.
Tugas ramalan hanyalah satu cara untuk mencapai tujuan; matlamatnya ialah matriks berat yang dipelajari yang barisnya menjadi benam perkataan yang padat.
Pensampelan negatif membingkaikan semula masalah sebagai klasifikasi binari terhadap beberapa perkataan rawak, mengelakkan softmax yang mahal melebihi puluhan ribu perkataan.
Mikolov et al. describe subsampling frequent words to speed training and learn more regular representations. The reported effect is scoped to the paper’s method and experiments.
Vektor Word2Vec mengekod perhubungan supaya analogi semantik boleh diselesaikan dengan penambahan dan penolakan vektor mudah.
