Word2vec can use either of two model architectures to produce these distributed representations of words: continuous bag of words (CBOW) or continuously sliding skip-gram. In both architectures, word2vec considers both individual words and a sliding context window as it iterates over the corpus.
Based on word2vec skip-gram, Multi-Sense Skip-Gram (MSSG) [35] performs word-sense discrimination and embedding simultaneously, improving its training time, while assuming a specific number of senses for each word. In the Non-Parametric Multi-Sense Skip-Gram (NP-MSSG) this number can vary depending on each word.
the set of 1-skip-2-grams includes all the bigrams (2-grams), and in addition the subsequences the in, rain Spain, in falls, Spain mainly, falls on, mainly the, and on plain. In skip-gram model, semantic relations between words are represented by linear combinations, capturing a form of compositionality.
N-gram is actually the parent of a family of names term, where family members can be (depending on n numeral) 1-gram, 2-gram etc., or the same using spoken numeral prefixes. If Latin numerical prefixes are used, then n -gram of size 1 is called a "unigram", size 2 a " bigram " (or, less commonly, a "digram") etc.
A language model is a model of natural language. [1] Language models are useful for a variety of tasks, including speech recognition, [2] machine translation, [3] natural language generation (generating more human-like text), optical character recognition, route optimization, [4] handwriting recognition, [5] grammar induction, [6] and information retrieval.

Prosecutors in Philadelphia issued a subpoena demanding everything related to the sale of Risperdal—business plans, emails, sales reports, clinical studies. The prosecutors had still not officially entered the qui tam cases, despite the theoretical 60-day deadline for making a decision once a relator and his lawyer filed a case in secret.
In its final phase, the algorithm employs Gensim's word2vec algorithm to learn embeddings based on biased random walks. [3] Sequences of nodes are fed into a skip-gram or continuous bag of words model and traditional machine-learning techniques for classification can be used. [4]
