Abstract

Texts are a common form to encode location information which can be used crucially in disaster scenarios. While Named Entity Recognition (NER) has been applied to location extraction from formal texts, its performance on informal and colloquial texts such as social media messages is unsatisfactory. The geo-entities in social media are often neglected or categorized into unknown or ‘other’ entity types such as person or organisation. In this paper we proposed a Bidirectional Long Short-Term Memory (LSTM) Neural Netwok to identify location information especially aiming to recognize rarely known local places in social media messages. The contribution of both syntactic and semantic features to the classification results was explored as well. The proposed method was validated on a Twitter dataset collected from typhoon-affected areas, showing promising performance in detecting location information.
