[PDF] Top 20 Neural Reranking for Named Entity Recognition

... We choose a basic discrete CRF model as our baseline tagger. As shown in Figure 3(a), discrete word features are first extracted as binary vectors (black and white circles) and then fed into a CRF layer. Taking those ... See full document

... Essentially, the constituent-based approach fil- ters out the other 3% named entities that cross constituent boundaries (Figure 3), i.e. 3% loss of recall. We dig into this problem by analyzing a sequential ... See full document

... In this study, we choose the BIOSE tag schema instead of standard BIO, where the B, I, O, S, E re- fer to the beginning, inside, outside, single and end of an entity, respectively. Previous work shows that BIOSE ... See full document

... Several other neural architectures have previously been proposed for NER. For instance, Collobert et al. (2011) uses a CNN over a sequence of word em- beddings with a CRF layer on top. This can be thought of as ... See full document

... As our model detects entities from inside to out- side, we keep the same order in preparing the gold labels for each word sequence. We call it the de- tection order rule. Meantime, we define that each entity ... See full document
