Named Entity Recognition by Neural Sliding Window

Named Entity Recognition (NER) is an important sub-task of document processing such as Information Extrac-tion. This paper describes a NER algorithm which uses a Multi-Layer Perceptron (MLP) to find and classify entities in natural language text. In particular we use the MLP to implement a new supervised context-based NER approach called Sliding Window Neural (SWiN). The SWiN method is a good solution for domains where the documents are grammatically ill-formed and it is difficult to exploit the fea-tures derived from linguistic analysis. Experiments indicate good accuracy compared with traditional approaches and demonstrate the system’s portability. 1
