Multilingual Europeana Users
• Native language browser: 69% • Native language Google (entry point): 91%
• Native language objects: 43% (SV 77%, DE 71%) à Native language use increases as soon as native language
content increases. Gäde, Maria (forthcoming). “User Behavior through the Language Glass” – Language-specific Behavior in Multilingual Digital Libraries.

Multilingual Interface in 31 Languages
• users seem to assume that search is affected
6
Query Result Filtering by Language
• language of record vs. language of content
7
Document Translation
• general MT – not domain-specific
8
Query Translation – Planned for 2013
• How many languages? • How much user interaction?
9
• concept (GEMET Thesaurus), agent (DBpedia), period (Semium time ontology), place (Geonames)

Semantic Enrichment
Poisonous India…

Enrichment Challenges
• Metadata quality & sparsity
• Vocabulary ambiguity
– domain GEMET print (German) Druck pressure
– language electrical Power (German) Strom (Czech) strom tree
– context Córdoba = Spain | Argentina
