Vector Representations of Words

One of the most significant advancements in the field of Natural Language Processing (NLP) over the past decade has been the development and adoption of vector representations for words. These representations, also known as word embeddings, are a type of word representation that allows words with similar meaning to have a similar representation.

Word vectors, also called word embeddings, are a type of word representation that bridges the human understanding of language to that of a machine. They are representations of words in a vector space, where the position of a word in the vector space is learned from text and is based on the words that surround the word when it is used. Word vectors are multi-dimensional meaning representations of words.

Benefits of Vector Representations of Words

  • They capture the semantic and syntactic similarities between words.
  • They can be used as input to machine learning algorithms to improve the performance of algorithms on tasks that involve natural language processing.
  • They allow for the exploration of word associations, similarity and dissimilarity between words, and more.

Models for Creating Vector Representations of Words

There are several models for generating word vectors, including continuous bag of words (CBOW), skip-gram, and GloVe. Each of these models has its strengths and weaknesses, and the choice of model often depends on the specific requirements of the task at hand.
