According to the original description of the Skip-gram model, published as a conference paper titled Distributed Representations of Words and Phrases and their Compositionality, the objective of this model is to maximize the average log-probability of the context words occurring around the input word over the entire vocabulary: (1) distributed representations of words and phrases and their the typical size used in the prior work.

These define a random walk that assigns probabilities to words. Paragraph Vector is an unsupervised algorithm that learns fixed-length feature representations from variable-length pieces of texts, such as sentences, paragraphs, and documents, and its construction gives the algorithm the potential to overcome the weaknesses of bag-of-words models. Most word representations are learned from large amounts of documents ignoring other information.
