Context-Dependent Fine-Grained Entity Type Tagging

Understand

Entity type tagging is the task of assigning category labels to each mention of an entity in a document.

• While standard systems focus on a small set of types, recent work (Ling and Weld, 2012) suggests that using a large fine-grained label set can lead to dramatic improvements in downstream tasks.
• In the absence of labeled training data, existing fine-grained tagging systems obtain examples automatically, using resolved entities and their types extracted from a knowledge base.
• However, since the appropriate type often depends on context (e.g.
