什么是知识图谱---Overall Title: 知识图谱的应用 (Applications of Knowledge Graphs) **Section 1: 个性化学习路径 (Personalized Learning Path)** * **Top Metrics and Chart:** * Knowledge Point: 复杂分子知识点 (Complex Molecular Knowledge Point) * Metric 1: 达成率 (Achievement Rate) 100% * Metric 2: 平均耗时 (Average Time Spent) 18.07% * Rank for both metrics: 排名: 1/共1人 (Rank: 1/Total 1 person) * Chart: Bar Chart titled 考试成绩 (Exam Score). Y-axis scale from 0 to 100. A bar for 考试成绩 shows a value of 18.07%. * Tabs: 相关任务详情 (Related Task Details), 资源推荐 (Resource Recommendation), 学习路径 (Learning Path) * **Knowledge Graph Diagram:** * Type: Node-link diagram representing a knowledge graph. * Elements: Nodes (circles) represent knowledge points, labeled with text such as: 复杂分子知识点, 原子轨道, 分子结构, 原子, 分子, 知识点子级, 知识点父级, 知识点子级 (上). Edges (arrows) connect nodes, indicating relationships or path direction. * Legend: Color scale indicating learning status based on percentage. * 80% - 100% (Green) * 60% - 79% (Yellow-Green) * 40% - 59% (Orange) * 20% - 39% (Red-Orange) * 0% - 19% (Red) * Legend Annotation: 代表当前知识点学习情况 (Represents current knowledge point learning status) * Explanation: 说明: 知识点颜色深浅代表学习情况, 颜色越绿学习情况越好。 (Explanation: The depth of knowledge point color represents learning status, the greener the color, the better the learning status.) **Section 2: 资源智能推荐 (Intelligent Resource Recommendation)** * **Top Metrics and Chart:** * Knowledge Point: 燃点 (Flash Point) * Metric: 掌握率 (Mastery Rate) 85% * Chart: Bar Chart titled 平均掌握率 (Average Mastery Rate). X-axis labels include 本班平均掌握率 (This class average mastery rate), 校级平均掌握率 (School level average mastery rate), etc. Bars show values like 85%, 75%, 80%, etc. * Tabs: 学生掌握详情 (Student Mastery Details), 相关任务详情 (Related Task Details), 资源推荐 (Resource Recommendation), 资源详情 (Resource Details) * **Knowledge Point Description:** * Title: 燃点 (Flash Point) * Text Description: 燃点是指易燃液体表面可燃气体与空气形成的混合物，在遇到火源时发生闪燃所需的最低温度。易燃液体的闪点越低，其危险性越大。不同的易燃液体具有不同的闪点。它们通常在常温常压下就能挥发出一定量的可燃蒸气。遇火即可引燃，闪点越低，越容易引燃。代表物有：酒精、汽油、乙醚等易燃液体。 (Flash point refers to the minimum temperature required for the mixture of flammable gas and air on the surface of a flammable liquid to flash when encountering a fire source. The lower the flash point of a flammable liquid, the greater its danger. Different flammable liquids have different flash points. They usually can volatile a certain amount of flammable vapor at normal temperature and pressure. When encountering fire, it can be ignited. The lower the flash point, the easier it is to ignite. Representative materials include: alcohol, gasoline, ether and other flammable liquids.) * **Related Knowledge Graph Diagram:** * Type: Node-link diagram. * Elements: Nodes (circles) labeled 燃点子级 (Flash Point Sub-level), 燃点 (Flash Point), 燃点父级 (Flash Point Parent level), and 燃点相关 (Related to Flash Point). Arrows connect the nodes. * **Resource Lists:** * Title: 本校推荐资源 (School Recommended Resources) * List of resources (likely files): * 4.2多晶硅的提纯.pdf (4.2 Purification of Polycrystalline Silicon.pdf) * 4.2多晶硅的提纯.pdf (4.2 Purification of Polycrystalline Silicon.pdf) * 4.3多晶硅的提纯.pdf (4.3 Purification of Polycrystalline Silicon.pdf) * 4.2多晶硅的提纯.pdf (4.2 Purification of Polycrystalline Silicon.pdf) * 4.2多晶硅的提纯.pdf (4.2 Purification of Polycrystalline Silicon.pdf) * Title: 相关知识点资源 (Related Knowledge Point Resources) * Resource Entry (Example): * [期刊] 基于知识图谱的化学燃烧知识点资源推送研究 (Journal) Research on Knowledge Point Resource Push of Chemical Combustion Based on Knowledge Graph * 作者 (Author): 许晓，吴晓亮，蒋文海 (Xu Xiao, Wu Xiaoliang, Jiang Wenhai) * 出处 (Source): 浙江理工大学学报(自然科学版), 2018(04): 462-470+516-516 (Journal of Zhejiang Sci-Tech University (Natural Science Edition), 2018(04): 462-470+516-516) * 关键词 (Keywords): 知识图谱; 资源推荐; 化学燃烧知识; 数据结构; 关联规则挖掘; 在线学习; 智能推送; (Knowledge graph; Resource recommendation; Chemical combustion knowledge; Data structure; Association rule mining; Online learning; Intelligent push;) * 摘要 (Abstract): [Textual abstract snippet, partially obscured] **Section 3: 精准化辅助线上教学 (Precision-assisted Online Teaching)** * **Top Tabs:** 按知识点统计 (Statistics by Knowledge Point), 按人统计 (Statistics by Person) * **Table: 按知识点统计 (Statistics by Knowledge Point)** * Headers: 知识点名称 (Knowledge Point Name), 平均完成率 (Average Completion Rate), 平均掌握率 (Average Mastery Rate), 课程资料人均阅读次数 (Average Number of Course Material Reads per Person), 操作 (Operation) * Rows: * 春秋战国 (Spring and Autumn Period and Warring States Period) * Data: 98%, 100%, 15, 查看 (View) * 百家争鸣 (Contention of a Hundred Schools of Thought) * Data: 98%, 100%, 15, 查看 (View) * Sub-item: 形成儒家、墨家、道家、法家 (Formation of Confucianism, Mohism, Taoism, Legalism) * Data: 98%, 100%, 15, 查看 (View) * Sub-item: 春秋: 孔子创立儒学 (Spring and Autumn: Confucius Founded Confucianism) * Data: 98%, 100%, 15, 查看 (View) * Annotation within table: 知识点最多支持6级 (Knowledge points support up to 6 levels) * 西汉时期 (Western Han Period) * Data: 98%, 100%, 15, 查看 (View) * 百家争鸣 (Contention of a Hundred Schools of Thought) * Data: 98%, 100%, 15, 查看 (View) * Sub-item: 形成儒家、墨家、道家、法家 (Formation of Confucianism, Mohism, Taoism, Legalism) * Data: 98%, 100%, 15, 查看 (View) * 宋朝时期 (Song Dynasty) * Data: 98%, 100%, 15, 查看 (View) * 明清时期 (Ming and Qing Dynasties) * Data: 98%, 100%, 15, 查看 (View)
