It disregards word order (and thus most of syntax or grammar) but captures multiplicity. The bag-of-words model is commonly used in methods of document classification where, for example, the (frequency of) occurrence of each word is used as a feature for training a classifier. [1] It has also been used for computer vision. [2]
Word2vec is a technique in natural language processing (NLP) for obtaining vector representations of words. These vectors capture information about the meaning of the word based on the surrounding words. The word2vec algorithm estimates these representations by modeling text in a large corpus.

In computer vision, the bag-of-words model (BoW model) sometimes called bag-of-visual-words model [1] [2] can be applied to image classification or retrieval, by treating image features as words. In document classification , a bag of words is a sparse vector of occurrence counts of words; that is, a sparse histogram over the vocabulary.
In February 2021, John Mueller, Webmaster Trends Analyst at Google, Tweeted, "I wouldn't worry about stop words at all; write naturally. Search engines look at much, much more than individual words.

Donald Trump posted a word cloud showcasing words like “revenge” and “dictatorship” from a Daily Mail poll asking what word voters use to describe a second term.
In information theory, linguistics, and computer science, the Levenshtein distance is a string metric for measuring the difference between two sequences. The Levenshtein distance between two words is the minimum number of single-character edits (insertions, deletions or substitutions) required to change one word into the other.
For example, Markdown plugins exist for every major blogging platform. [ 12 ] While Markdown is a minimal markup language and is read and edited with a normal text editor , there are specially designed editors that preview the files with styles, which are available for all major platforms.
