Context-Dependent Fine-Grained Entity Type Tagging [article]

Dan Gillick, Nevena Lazic, Kuzman Ganchev, Jesse Kirchner, David Huynh
2016 arXiv   pre-print
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.  ...  We propose the task of context-dependent fine type tagging, where the set of acceptable labels for a mention is restricted to only those deducible from the local context (e.g. sentence or document).  ...  We have prepared extensive new resources related to the context-dependent fine type tagging task.  ...
