提出了一种自动构造特定领域本体的方法，该方法应用术语抽取和多重聚类技术。在术语抽取阶段，通过术语在专业语料与背景语料中出现概率的对比，采用LLR公式对术语进行评分，取得了更好的抽取效果。在层级关系发现过程中，采用上下文共现信息结合HowNet中词语的语义相似度，进行术语间相似度度量，力求获得术语间最合理的相关状况。同时改进了k-medoids聚类算法，更准确地发现术语的层级关系，进而构造出特定领域的本体。(This paper presents an approach to mining domain-dependent ontologies using term extraction and relationship discovery technology.There are two main innovations in the approach. One is extracting terms using log-likelihood ratio, which is based on the contrastive probabilityofterm occurrence in domain corpus and background corpus. The other is fusing together information from multiple knowledge sources as evidencesfor discovering particular semantic relationships among terms. In the experiment, traditional k-mediods algorithm is improved for multi-levelclustering. The approach to produce an ontology for the domain of computer science is applied and promising results are obtained.)

空间矢量异步电机变频器-
我们设计的异步电机变频调速器以TMS320F28035芯片为控制核心，通过输出三相PWM波控制智能功率模块IPM驱动三相异步电机。我们使用空间矢量SVPWM算法，并对其进行了优化。采用异步电机无传感器测速算法省去了昂贵的光电编码器，大大节省了成本。同时开创性的研发了自动根据运行环境调节的自适应变频算法，使我们的变频调速器可以在电网条件恶劣的乡村山区工作，由此该变频器已被一家民用水泵生产企业预订。(We design the asynchronous motor frequency conversion governor with TMS320F28035 chip as the control core, and output three-phase PWM wave to control the intelligent power module IPM to drive the three-phase asynchronous motor. We use space vector SVPWM algorithm and optimize it. The sensorless speed measurement algorithm of asynchronous motor eliminates the expensive photoelectric encoder and greatly saves the cost. At the same time, pioneering research automatic conversion algorithm based on adaptive adjustment of the operating environment, we can make VVVF in power grid conditions of rural area, thus the inverter has been a civil pump manufacturer reservation.)
