Work from 2002, presented at the ASIST IA summit, Baltimore, USA - republished here as supplement to Martin Belam's series of posts on the history of BBC Search.
27. Taxonomy tool – top level screen Top level of the hierarchical tree structure taxonomy. Shows all our subject areas plus a test node for playing around and a xyzxyz node which reflects our most popular query – nothing! i.e. "". We couldn't have an entry for nothing so we had to equate a search for no string with something to give us a node. We then had to have that node as top level node because otherwise it would inherit context from its parent.
28. Taxonomy tool – node level screen Shows screen for “ Question of Sport ” which has a parent - BBC programmes - and children - the presenter's names. Each node also has urls and synonyms attached. Each url has a label (title), a description, score (crude method to indicate which url is most relevant to the node). Each url has the possibility of having an expiry date which can be reviewed and the url can be archived after expiring.
29. Taxonomy tool – synonyms Shows a node with numerous urls attached and scored Plus numerous synonyms The children are all aspects of WW2 – often these are based on programme content on BBC TV or radio (e.g. documentary on Monte Cassino being shown, therefore people likely to enter as a search term)
