What is a WordPress?
The MRC Psycholinguistic Database project in the early 1980's made various linguistic and psychology data sets more widely available to language and knowledge engineering researchers. The project developed the database consisting of datasets from various sources and although available for local use this requires software installation on a UNIX system and a reasonable amount of computing skill to use. The recommended option is to use an intermediary such as a web interface and the wordpress is one such intermediary.
The "wordpress" literally means to press out the words - you enter your selection requirements for words and then at the press of a button words are extracted or pressed from the database.
What is a Psycholinguistic Database?
This is a machine usable dictionary containing approximatley 150,000 words with up to 26 linguistic and psycholinguistic attributes for each. The dictionary may be of use to researchers in psychology or linguistics to develop sets of experimental stimuli, or those in artificial intelligence and computer science who require psychological and linguistic descriptions of words.
