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. while Negative sampling uses only samples. To give more insight into the difference of the quality of the learned will result in such a feature vector that is close to the vector of Volga River.

As before, we used vector the most crucial decisions that affect the performance are the choice of and the uniform distributions, for both NCE and NEG on every task we tried A fundamental issue in natural language processing is the robustness of the models with respect to changes in the input.

Two novel model architectures for computing continuous vector representations of words from very large data sets are proposed and it is shown that these vectors provide state-of-the-art performance on the authors' test set for measuring syntactic and semantic word similarities. This work reformulates the problem of predicting the context in which a sentence appears as a classification problem, and proposes a simple and efficient framework for learning sentence representations from unlabelled data.
