User keywords, or 'tags', are words added to object records by other users to enhance their discovery. You can add keywords that may be useful in helping others find this object.

We are experimenting with tagging because sometimes museums describe objects in language that is highly specialist and user added keywords are useful in bridging the 'semantic gap' between the language of the museum and that of the user.

Any keywords listed have been added by other users like yourself. You can click on them to use them as search terms to dicover other objects. User tags
Here you can find links to other objects in our collection that belong to the same formal classification categories as the object you are viewing. Similar objects

'Autogenerated tags' are a new feature that we are testing. These tags are generated by passing the object record through the OpenCalais service from Reuters. This service makes a 'best guess' at the names, places, companies and specialist terminolgy that is in the text of the object records.

By clicking on a tag you can find all other collection records related to that person, place or company.

Because the tags are autogenerated there are likely to be some errors. If you spot one of these then please flag the tag for deletion by clicking the 'x'. Auto-generated tags: [Beta]
