Performing Named Entity Recognition (NER) with Unreliable Spacing












0












$begingroup$


I have a large corpus of physical places I would like to apply named entity recognition to. The places are typically short strings, but due to human typos often have critical spaces missing, e.g., "bob's hoteltoronto ontario". I should also add that all of the strings are entirely lowercase, hence my inclination to use a neural network here.



To take the example above, I would like the model to recognize "bob's hotel", "toronto" and "ontario" as separate nouns. However, when I look up how to structure training data for NER models, they always seem to rely on the presence of spaces, e.g.:



U.N. NNP I-NP I-ORG 
official NN I-NP O
Ekeus NNP I-NP I-PER
heads VBZ I-VP O


(Source: CoNLL 2003 dataset)



So, in short, I would like to train my model with some examples that do not contain the correct spaces, such as in the example above. How can I do this?



Notes:




  • One solution, of course, is to use an algorithm to split the data ahead of time (e.g., wordnija). However, I would prefer to leave this for the net to solve.


  • I should add that I have loads of labeled data.
