With the advancement of diverse industries, text clustering has garnered significant attention in fields such as data mining, document retrieval, and pattern classification. The K-Means algorithm, a simple, efficient, and widely adopted clustering approach, has been extensively studied for its applicability in text data analysis. However, the exponential growth of information presents a formidable challenge when clustering large-scale data. The traditional K-Means algorithm proves ineffective in handling high-dimensional, massive text data, and the initial centroid selection significantly impacts the clustering outcomes. To address these limitations, this research introduces a clustering algorithm based on the virtual centroid and nearest centroid strategy. Furthermore, we incorporate the MapReduce parallelization framework to tackle the clustering problem associated with vast text data. Experimental results demonstrate the algorithm's commendable scalability and effective handling of large datasets. © 2023 ACM.

Underwater sensor networks are widely used in water quality monitoring and underwater resources detection. The deployment of sensor nodes greatly affects the monitoring performance of the network. After the initial deployment of underwater sensor nodes, due to the influence of water flow, the sensor nodes will deviate from the initial position, which will affect the coverage of the network. Therefore, an effective algorithm is needed to deploy the underwater sensor networks. In this paper, MCM flow movement model is introduced to simulate the influence of water movement on sensor node position. Then, the Hungarian algorithm is used to redeploy the sensor nodes. The simulation results show that, compared with direct movement, Hungarian algorithm can achieve the effective deployment of the network with less mobile distance and better prolong the network life cycle. © 2021, Springer Nature Switzerland AG.

Point-of-Interest (POI) recommendation is one of the most important tasks in the research of Location-based Social Networks (LBSNs). To solve the spatial sparsity problem in POI recommendation, this study proposed a recommendation model based on graph autoencoder (GAE) and long short-term preferences applied to location recommendation. Firstly, the POI transfer map of the check-in sequence is constructed, from which the hidden links between each POI are extracted using GAE to alleviate the troubles caused by data sparsity. Secondly, a long short-term preference extraction module is incorporated into the model, considering the influence of user preferences on user decisions. Finally, the proposed GELS model was tested on the Foursquare dataset and compared with results from other models. The GELS model in this study achieved Recall@10 scores of 0.6933 and 0.5099 on two different datasets, surpassing other models and demonstrating its superior performance in POI recommendation. The results show that GELS model can provide new ideas for POI recommendations. © 2023 ACM.

In the hierarchical storage system, the data value needed to be evaluated to formulate rules data for hierarchical storage and migration. To further research the data hierarchical storage system in railway construction period and how to allocate the resources of the storage media with different performances, the researches on evaluation of the data value in railway construction period were pursued in the paper. Based on the business and non-business characteristics of the railway construction period, the evaluation indicator system of data value in railway construction period were designed, which can provide a comprehensive reference for the model. Combined with the quantification standard of evaluation indicators of data value in railway construction period designed in this paper, the complexity of indicator measurement can be reduced. In order to further improve the accuracy of model evaluation and meet data storage requirements, a comprehensive data value evaluation of railway construction period based on analytic hierarchy process (AHP)-grey clustering method was proposed. A simulation was carried out based on the data actually stored in a railway construction period, and the applicability of the model in the hierarchical storage system was proved by the geometric distribution of the results. In order to further verify the accuracy of the data value evaluation model proposed in this paper, its evaluation results were compared with that of the traditional model based on the same group of data. Experimental results shown that the data value model proposed in this paper was more accurate and adaptable than the traditional model in railway construction period, and can better meet the application requirements of the actual railway hierarchical storage system. © 2022 SPIE.

Aiming at metro shield disease detection with LiDAR scanning data, this paper proposes an approach of distributed parallel point cloud data processing and shield disease detection. The approach is based on HDFS and Spark, and converts the LiDAR point cloud data into the orthographic projection space, and generates projected image data efficiently. Based on the optimized deep neural network YOLOv5 target detection model, our approach detects four types of metro shield diseases and labels their locations and the classifications on the orthographic projection image. The experiments show that our distributed parallel process framework archives the speedup ratio of 4.96 to the approach of a single server on the LiDAR data processing. Using the optimized YOLO v5 model, with the appropriate IOU threshold, the accuracy of the water seepage and spalling detection box is higher than 90%, and that of the cracks and the cracks on joints is higher than 80%. Our approach can improve the efficiency and accuracy of metro shield disease detection significantly, and promote the intelligence of metro operation and maintenance in the rail transit industry. © 2022, The Author(s), under exclusive license to Springer Nature Switzerland AG.

In order to meet the continuous improvement of real-time performance, positioning accuracy and robustness for visual Simultaneous Localization and Mapping (SLAM), and to address the problem that sparse maps are difficult to directly use for autonomous navigation, a semi-direct visual SLAM algorithm based on improved keyframe selection is proposed. It is based on ORB-SLAM2 framework. The front-end fuses feature-based method and direct method to get the camera initial poses. By minimizing the re-projection error to optimize the pose, it obtains a more accurate pose estimation. The proposed redundant keyframe deletion algorithm is applied in the back-end. It is based on the relative motion distance between keyframes, so as to delete the keyframes with overlapping visual fields and reduce the number of keyframes. The filtered keyframes are used for closed-loop detection and dense point cloud map construction. Then the map is filtered and converted into an octree map with higher storage efficiency. Experiments show that the algorithm can improve the real-time performance while ensuring the positioning accuracy, and has strong robustness to the sparse texture or camera’s fast-moving scene, and it can reconstruct the 3D maps of different environment.

This paper proposes a server-client mutual selection strategy based on multiple resource indicators, providing a balanced selection algorithm for edge compu-ting services for industrial Automated Guided Vehicles (AGVs). Firstly, based on the service popularity and Zipf's law, the type of service primarily carried by each Remote Unit (RU) is determined, and RUs are divided into work area slices based on the similarity of service popularity. Nest, the AGV side first sends a forward service request to the RU side based on the requirements and urgency of work tasks, and then the RU side reversely selects the AGV from the perspective of optimal resource allocation. This paper comprehensively considers multiple factors such as matching of process service content, user de-lay limit, and computing and communication resources, and can solve the problem of dynamically allocating resources in the edge-cloud computing network in a balanced matching manner in scenarios like intelligent factories and ports. Simultaneously, this paper adopts the strategy of bidirectional selection, achieving a trade-off between user experience and economic benefits for users and operators.
