Abstract EN
Wide attention has been paid to named entity recognition (NER) in specific fields.
Among the representative tasks are the aspect term extraction (ATE) in user online comments and the biomedical named entity recognition (BioNER) in medical documents.
Existing methods only perform well in a particular field, and it is difficult to maintain an advantage in other fields.
In this article, we propose a supervised learning method that can be used for much special domain NER tasks.
The model consists of two parts, a multidimensional self-attention (MDSA) network and a CNN-based model.
The multidimensional self-attention mechanism can calculate the importance of the context to the current word, select the relevance according to the importance, and complete the update of the word vector.
This update mechanism allows the subsequent CNN model to have variable-length memory of sentence context.
We conduct experiments on benchmark datasets of ATE and BioNER tasks.
The results show that our model surpasses most baseline methods.
