Wordnet-based search engine for picdiary

This search engine uses wordnet to find synonyms of search terms, and hypernyms of marked-up keywords. So a search for skyscraper finds one picture and a search for structure finds the skyscraper and a load of other pictures too.

The pics are marked up in the RSS-based picture collections using markup like this:

<item rdf:about="http://www.picdiary.com/kensington/img_1926.jpg">
<foaf:depicts><wordnet:Telephone /></foaf:depicts>
</item>

Search results are actually returned in RSS; the html search page is just a wrapper around that. So you can subscribe to pictures of shops if you really want to.

Next steps:

• Add "more like this" links to picture pages that find pictures by navigating the wordnet space


• make a dmoz-style directory of pictures arranged into the wordnet hierarchy


• do similar things with FOAF person information


• do location annotation using jo's geonet-based namespace


• tie it all together into some sort of coherent website
