This free service is not intended for repeated submissions from the same site. Limits will be placed on high usage. Our tagging service is available if you have large amounts of text to tag. Special arrangements can be made if you would like to use this page in lab teaching sessions for example. The limit on the number of words per use is based on whether you are accessing this page from an computer on an academic network or other. For example, IP addresses ending in .ac.uk, .edu, .ust.hk and .ac.jp are classified as academic users. If you are accessing this site from other academic networks, please let me know so that I can increase the limit on the number of words for that domain. Please contact Paul Rayson (email: paul at comp.lancs.ac.uk), also use this address if you have technical problems.
