2. Research foci Information extraction Social network analysis
Distributed architecture evaluation and optimization for time-critical Big Data applications

3. Entity Linking Some name conventions!
Instance: a particular person, location (GPE), organization, ...
Entity: text + type

4. Strategy Semantic coherence (in terms of ranking)
“An instance would have a high ranking value if the instances that typically co-occur with it also have high ranking values”
