Dictionary data for language researchers

Cambridge University Press is happy to consider requests to use its dictionary data in natural language processing or other electronic applications. The two most common types of licence are:

• A standard commercial licence allows a single company to use the data for any research, and also allows its use in any number of products at no extra cost, providing that none of the dictionary data is reverse engineerable, and that the products are not and do not include paper or electronic dictionaries.

• A standard university department research licence allows for research use by any number of researchers in a university department for a 3 year period, but does not allow for any product development.

There are a number of dictionary databases available, and we can consider customising data sets on demand. All data will be supplied as SGML-encoded files on PC-recordable CDs. Prices start from £500, depending on the data set, licence term, number of commercial products, and size of the institution or company. For more details email cald@cambridge.org.
