The UPV/EHU-University of the Basque Country's IXA Group has enhanced the use of the vast Europeana digital library, analyzing and enriching the archive's content through the use of language technologies to improve user searches and deliver more comprehensive information. This effort is a component of Europe's Personalised Access To Cultural Heritage Spaces project which, among other things, offers guided tours of the library's cultural works.

"However, some of the cultural items [content] in these guided tours tend to have a limited description or provide little information, and the user sometimes ends up wanting to know more," says the IXA Group's Eneko Agirre.

The addition of language technology facilitates a way for content of similar interest to users to be suggested to them. Users are provided a list of similar items, thanks to organization by subject. For example, Wikipedia links are added for external resources, while users also receive assistance so they can more easily interpret the information. Among the methods the IXA group researchers have used for enhancing Europeana are machine learning; text corpora; terminology extraction; text comprehension; disambiguation, and linguistic, morphological, and syntactic analysis.
