军事分析仿真评估系统模糊知识库研究

指挥员的决策需要大量的军事知识和态势信息,对于军事分析仿真评估系统,建立指挥控制模型更需要有详细的知识支撑,知识库的完备性对指挥控制模型的运行速度和效率具有决定性的影响。但真实的战场决策环境下存在着大量的模糊信息,能否很好地处理模糊信息成为制约知识库进一步发展的关键因素。因此,在深入研究军事分析仿真评估系统知识库的基础上,重点介绍了其模糊拓展的数据模型设计,最后通过实例验证了模型的正确性。     

一种融合实体语义知识的实体集合扩展方法

实体集合扩展是开放式信息抽取的一个重要问题,该问题研究如何从一个语义类的若干实体(称为种子)出发,得到该类别的更多实体。现有实体集合扩展方法主要使用上下文模板或种子在语料中的分布信息进行抽取,其缺点是无法解决种子的歧义问题,而该问题会影响方法的有效性。在该文中,作者提出了一种融合实体语义知识的实体集合扩展方法,通过引入语义知识来解决种子歧义性问题。新方法通过使用Wikipedia实现了语义知识的引入,并把基于语义知识的扩展方法和基于模板的扩展方法相融合。实验表明,与单纯基于上下文方法相比,该文方法在准确率上提升了18.5%,召回率上提升了6.8%,MAP值上提升了22.8%。     

Semantic-based web service discovery and chaining for building an Arctic spatial data infrastructure

Increasing interests in a global environment and climate change have led to studies focused on the changes in the multinational Arctic region. To facilitate Arctic research, a spatial data infrastructure (SDI), where Arctic data, information, and services are shared and integrated in a seamless manner, particularly in light of today's climate change scenarios, is urgently needed. In this paper, we utilize the knowledge-based approach and the spatial web portal technology to prototype an Arctic SDI (ASDI) by proposing (1) a hybrid approach for efficient service discovery from distributed web catalogs and the dynamic Internet; (2) a domain knowledge base to model the latent semantic relationships among scientific data and services; and (3) an intelligent logic reasoning mechanism for (semi-)automatic service selection and chaining. A study of the influence of solid water dynamics to the bio-habitat of the Arctic region is used as an example to demonstrate the prototype.     

Multi‐agent system for knowledge‐based event recognition and composition

This work presents a multi‐agent system for knowledge‐based high‐level event composition, which interprets activities, behaviour and situations semantically in a scenario with multi‐sensory monitoring. A perception agent (plurisensory agent and visual agent)‐based structure is presented. The agents process the sensor information and identify (agent decision system) significant changes in the monitored signals, which they send as simple events to the composition agent that searches for and identifies pre‐defined patterns as higher‐level semantic composed events. The structure has a methodology and a set of tools that facilitate its development and application to different fields without having to start from scratch. This creates an environment to develop knowledge‐based systems generally for event composition. The application task of our work is surveillance, and event composition/inference examples are shown which characterize an alarming situation in the scene and resolve identification and tracking problems of people in the scenario being monitored.
