    Research on a knowledge-defined polymorphic network attainable service architecture by Jingyu WANG, Zirui ZHUANG

    Published 2022-04-01
    “…Given the consideration of future generation mobile communication network systems with decoupled administration, control, and data planes, a knowledge-defined polymorphic network (KDPN) attainable service architecture was proposed.In the proposed architecture, while mimicking the biological polymorphism, “network knowledge” was acted as a genetic core connecting all the planes, where local network knowledge was extracted from different scenarios and layers of the network.By constructing a network knowledge graph with unified logic, and depending on the service requirement for specific knowledge, different local knowledge could be exchanged and collaborated.Network knowledge will provide guidance and foundation for general network optimization and management across different service scenarios, service layers, and service objectives.KDPN will help the communication networks cope with sophisticated and dynamic service demands and provide dynamic and diversified services to general users promptly and effectively with quality of experience assurances.…”

    Graph neural network-based address classification method for account balance model blockchain by Zhiyuan LI, Binglei XU, Yingyi ZHOU

    Published 2023-09-01
    “…To regulate the transactional activities on the public blockchain involving account balance models, it is necessary to conduct research on address classification for transactions on such blockchains.A blockchain address classification method, named AJKGS-ABCM (attention jumping knowledge graph SAGE account-based blockchain classification model), was proposed to categorize blockchain addresses, providing effective support for blockchain transaction tracking.Blockchain transaction data was represented as a graph structure, with addressed as nodes and transactions as edges.The AJK-GraphSAGE algorithm was introduced to learn embedded representations of the graph, where the model’s input required only nodes and their sampled neighboring node sets.Simultaneously, attention mechanisms and skip-connection knowledge integration strategies were incorporated into the model, allowing for adaptive weight allocation across different layers and information sharing between various levels, thereby enhancing training speed and generalization capabilities.Finally, experimental comparisons are conducted, demonstrating superior performance in terms of accuracy, recall, and F1 score compared to other methods.…”

    Cyber security entity recognition method based on residual dilation convolution neural network by Bo XIE, Guowei SHEN, Chun GUO, Yan ZHOU, Miao YU

    Published 2020-10-01
    “…In recent years,cybersecurity threats have increased,and data-driven security intelligence analysis has become a hot research topic in the field of cybersecurity.In particular,the artificial intelligence technology represented by the knowledge graph can provide support for complex cyberattack detection and unknown cyberattack detection in multi-source heterogeneous threat intelligence data.Cybersecurity entity recognition is the basis for the construction of threat intelligence knowledge graphs.The composition of security entities in open network text data is very complex,which makes traditional deep learning methods difficult to identify accurately.Based on the pre-training language model of BERT (pre-training of deep bidirectional transformers),a cybersecurity entity recognition model BERT-RDCNN-CRF based on residual dilation convolutional neural network and conditional random field was proposed.The BERT model was used to train the character-level feature vector representation.Combining the residual convolution and the dilation neural network model to effectively extract the important features of the security entity,and finally obtain the BIO annotation of each character through CRF.Experiments on the large-scale cybersecurity entity annotation dataset constructed show that the proposed method achieves better results than the LSTM-CRF model,the BiLSTM-CRF model and the traditional entity recognition model.…”
