A Dense Continuous Word Modeling System is a Word Embedding System that is a continuous word vector space modeling system that implements a dense continuous word vector space modeling algorithm (to solve a dense continuous word vector space modeling task which requires a dense continuous word model).

- Dense vector models have dimensionality 50–1000. Word2vec algorithms like skip-gram are a popular way to compute dense embeddings. Skip-gram trains a logistic regression classifier to compute the probability that two words are ‘likely to occur nearby in text’. This probability is computed from the dot product between the embeddings for the two words.
