The Ngram tool in Gale Digital Scholar Lab visualises the frequency of the most commonly occurring words or phrases within the documents of a Content Set. 

An Ngram is a sequence of words, where N represents the number of words. A 1gram, or unigram, is a single word; a 2gram, or bigram, is a two-word phrase etc. In Gale Digital Scholar Lab, the Ngram tool can be used to compile search terms or words that are often associated with one another. The tool can help determine if a Content Set contains specific terminology or phrases, which otherwise can be difficult to trace without intensive reading of individual documents. By providing insight into the text of documents, Ngrams can provide useful feedback to a user about their close and distant reading strategies by illuminating how writers used vocabulary or phrases.  

A versatile analysis, the Ngram tool can also be used to influence the Cleaning Tool configuration by identifying commonly misspelled or mis-captured words in the documents.
