Formally, a k-skip-n-gram is a length-n subsequence where the components occur at distance at most k from each other. For example, in the input text: the rain in Spain falls mainly on the plain. the set of 1-skip-2-grams includes all the bigrams (2-grams), and in addition the subsequences
In the continuous skip-gram architecture, the model uses the current word to predict the surrounding window of context words. [1] [2] The skip-gram architecture weighs nearby context words more heavily than more distant context words. According to the authors' note, [3] CBOW is faster while skip-gram does a better job for infrequent words.
The model has been used in lexical substitution automation and prediction algorithms. One such algorithm developed by Oren Melamud, Omer Levy, and Ido Dagan uses the skip-gram model to find a vector for each word and its synonyms. Then, it calculates the cosine distance between vectors to determine which words will be the best substitutes. [2]

node2vec is an algorithm to generate vector representations of nodes on a graph. The node2vec framework learns low-dimensional representations for nodes in a graph through the use of random walks through a graph starting at a target node.
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]
Skip-thought vectors are an attempt to create a vector representation of the semantic meaning of a sentence, similarly to the skip gram model. [15] Skip-thought vectors are produced through the use of a skip-thought model which consists of three key components, an encoder and two decoders. Given a corpus of documents, the skip-thought model is ...
