摘要:受知识图谱广泛应用和教育领域日益增长的需求的推动,我们提出了一个名为 KnowEdu 的系统,用于自动构建教育知识图谱。通过利用教育领域的异构数据(例如教学数据和学习评估数据),该系统首先提取科目或课程的概念,然后识别概念之间的教育关系。更具体地说,它对教学数据采用神经序列标记算法来提取教学概念,并对学习评估数...
Firstly, learners build the subgraphs to acquire knowledge through the crowd-sourcing task; secondly, we put forward the fusion strategy of knowledge subgraph, in which knowledge graph is converted into the adjacency matrix, and the weight of the knowledge relation is calculated by matrix operations...
Knowledge graph is a kind of semantic network for information retrieval. How to construct a knowledge graph that can serve the power system based on the behavior data of dispatchers is a hot research topic in the area of electric power artificial intelligence. In this paper, we propose a meth...
1.3. Knowledge: Definition: Organized information that forms a coherent understanding or a set of rules. Role in ACS: Informs the system's reasoning capabilities, allowing it to apply logic and previous experiences to new situations. 1.4. Wisdom: Definition: The ability to apply knowledge effective...

Note: the covering relation is utilized in the covering graph which is a convenient way to graphically represent a poset. Next we introduce two ways to ‘add’ two partial orders, namely parallel addition and serial addition. Definition 2 If (P1,≤1) and (P2,≤2) are two partial orders ...

Shown are the predictions for six of the eleven predictors we tested: fixed parameter value-guided construal modification obstacle probability (VGC, our model); trajectory-based heuristic search obstacle hit score (Traj HS); graph-based heuristic search obstacle hit score (Graph HS); distance to ...
Constructing Dynamic Brain Functional Networks via Hyper-Graph Manifold Regularization for Mild Cognitive Impairment Classification. Brain functional networks (BFNs) constructed via manifold regularization (MR) have emerged as a powerful tool in finding new biomarkers for brain disease d... Y Ji,Y Zhang...
