The TAC 2009 Knowledge Base Population Track (, might be a good place to look to get an idea of the community's approaches for addressing some of the points you've raised. The task consists of two subtasks: Entity-Linking and Slot-Filling. Entity-Linking focuses on resolving entities, given mentions in documents. Unlike previous entity-resolution tasks, the task here is to map mentions to entities in a knowledge-base (or to declare that the entity is unknown). Slot-Filling focuses on extracting facts and relationships about a given entity from a set of target texts.

Although the conference itself is occurring in November, there's at least one work out there that addressed entity-linking.
