The number of devices equipped with GPS sensors has increased enormously, which generates a massive amount of data. To analyse this huge data for various applications is still challenging. One such application is to predict the future location of an ambulance in the healthcare system based on its previous locations. For example, many smart city applications rely on user movement and location prediction like SnapTrends and Geofeedia. There are many models and algorithms which help predict the future location with high probabilities. However, in terms of efficiency and accuracy, the existing algorithms are still improving. In this study, a novel algorithm, NextSTMove, is proposed according to the available dataset which results in lower latency and higher probability. Apache Spark, a big data platform, was used for reducing the processing time and efficiently managing computing resources. The algorithm achieved 75% to 85% accuracy and in some cases 100% accuracy, where the users do not change their daily routine frequently. After comparing the prediction results of our algorithm, it was experimentally found that it predicts processes up to 300% faster than traditional algorithms. NextSTMove is therefore compared with and without Apache Spark and can help in finding useful knowledge for healthcare medical information systems and other data analytics related solutions especially healthcare engineering.
配备 GPS 传感器的设备数量大大增加,产生了大量数据。分析这些大数据用于各种应用仍然具有挑战性。其中一个应用是根据救护车之前的位置来预测医疗保健系统中救护车的未来位置。例如,许多智慧城市应用程序依赖于用户的移动和位置预测,例如 SnapTrends 和 Geofeedia。有许多模型和算法可以帮助以较高的概率预测未来位置。然而,在效率和准确性方面,现有的算法仍在不断改进。在这项研究中,根据可用数据集提出了一种新算法 NextSTMove,从而降低了延迟并提高了概率。大数据平台 Apache Spark 用于减少处理时间和有效地管理计算资源。该算法的准确率达到 75%到 85%,在某些情况下甚至达到 100%,前提是用户不会频繁改变日常生活习惯。在比较了我们算法的预测结果后,实验发现它的预测速度比传统算法快 300%。因此,NextSTMove 与 Apache Spark 一起或不与 Apache Spark 一起进行了比较,可以帮助寻找医疗保健医疗信息系统和其他数据分析相关解决方案(特别是医疗保健工程)的有用知识。
