Hi all,

DBpedia provides Linked Data URIs for 2.6 million things. However, it
wasn't always easy in the past for other Linked Data publishers to find
a DBpedia URI.

DBpedia Lookup [1] aims to fill that gap. It provides a service to find
the most-likely DBpedia URIs for a given keyword. The underlying
algorithm ranks DBpedia resources based on their relevance in Wikipedia
and includes synonyms into the index.

Try the terms "Shakespeare", "EU", or "Cambridge" and see for yourself
if the results you'd expect show up at the top. The result ranking is
different - and supposed to be more useful - than a simple full-text
search or SPARQL-Query with embedded regular expression for matching
labels.

There is a web-service available at [2]. You can use the KeywordSearch
method for searching full terms (as you see at [1]), and the
PrefixSearch method for an autocompletion-style interface such as the
one you see at [3]. The webservice returns a list of resource URIs with
English abstracts, dbpedia classes and categories.

Feel free to use the service as you like. If you plan to use it in a
production system or to run a high-load batch process, please drop me a
message to let me know. Thanks.

I hope that DBpedia Lookup is useful for you, and I'd appreciate any
feedback.

Many thanks to the semantic web folks at the BBC for their support and
feedback on the development of DBpedia Lookup.


Cheers,
Georgi
