Abstract

Twitter is one of the most popular micro-blogging and social networking platforms where users post their opinions, preferences, activities, thoughts, views, etc., in form of tweets within the limit of 280 characters. In order to study and analyse the social behavior and activities of a user across a region, it becomes necessary to identify the location of the tweet. This paper aims to predict geolocation of real-time tweets at the city level collected for a period of 30 days by using a combination of convolutional neural network and a bidirectional long short-term memory by extracting features within the tweets and features associated with the tweets. We have also compared our results with previous baseline models and the findings of our experiment show a significant improvement over baselines methods achieving an accuracy of 92.6 with a median error of 22.4 km at city level prediction.

摘要

推特是最受欢迎的微博和社交网络平台之一,用户可以在该平台上以推文的形式,在280字符的限制内发布他们的意见、偏好、活动、想法、观点等。为了研究和分析某个地区用户的社会行为和活动,确定推文的位置变得很有必要。本文旨在通过结合卷积神经网络和双向长短期记忆网络,利用推文中的特征以及与推文相关的特征,预测在30天内收集的城市级实时推文的地理位置。我们还将我们的结果与之前的基线模型进行了比较,实验结果表明,与基线方法相比有显著改进,在城市级预测中准确率达到92.6%,中位数误差为22.4公里。
