Exploring the State Papers with Word Embeddings

One way we can represent text in a way that a machine can interpret is with a word vector. A word vector is simply a numerical representation of a word within a corpus (a body of text, often a series of documents), usually consisting of a series of numbers in a specified sequence. This type of representation is used for a variety of Natural Language Processing tasks – for instance measuring the similarity between two documents.

A new blog post by the team uses a couple of R packages and a method for creating word vectors with a neural net, called GloVe, to produce a series of vectors which give useful clues as to the semantic links between words in a corpus. The method is then used to analyse the printed summaries of the State Papers Online, and show how they can be used to understand how the association between words and concepts changed over the course of the seventeenth century.
