Nested Named Entity Recognition: A Survey
With the rapid development of text mining, many studies observe that text generally contains a variety of implicit information, and it is important to develop techniques for extracting such information. Named Entity Recognition (NER), the first step of ...
Incorporating Boundary and Category Feature for Nested Named Entity Recognition
Database Systems for Advanced ApplicationsAbstractIn the natural language processing (NLP) field, it is fairly common that an entity is nested in another entity. Most existing named entity recognition (NER) models focus on flat entities but ignore nested entities. In this paper, we propose a ...
Recursive label attention network for nested named entity recognition
AbstractNested named entity recognition (NER) has been mainly studied by recognizing inner entities first, then outer entities, or vice versa, depending on the nesting level. However, the previous models on nested NER do not deal with the data sparseness ...
Highlights- We propose a recursive method to improve the nested named entity recognition.
- Recursively calculates attention mechanism between word and label embedding.
- Effectively re-uses lower-level label embeddings by level-reflected label ...
