Firstly syntax parsing tools are used to extract context feature of terms, and natural language feature and statistical mutual information measure are integrated to compute relevancy degree of terms,then dynamic role and sememe are used as key to seek the relationship in HowNet semantic relationship framework, and explicit semantic lable is designated to the relationship.

首先通过句法分析提取术语的上下文特征，结合自然语言特征和互信息的方法计算术语之间的相关度，然后使用术语的义原和动态角色作为关键词，在知网语义关系框架中定位关系，并为关系指定明确的语义标签。

First, the character clustering algorithm regards the character as our features and then it can cluster these sentences of our target words to the correct group without any other resources. The average precision is 66.1%. Second, in the concept clustering algorithm of the aggregate computing, we use HowNet as the knowledge base of our feature words and obtain the concepts of these words. We cluster the sentences which have the same or similar concepts of the feature words into the same group. And then we can complement some lacks of the character clustering algorithm. The average precision is 72.3%. Third, regarding the concept clustering algorithm of the sememe distance, we use the sememe distance to compute its concept similarity. It improved similarity measure of the concept clustering algorithm of the aggregate computing. It achieves 81% average precision and gets better cluster quality.

词形分群演算法不受语料资源限制，能将词形相似且词义相近的词汇所属的句子分到同一群，经过人工验证，得到了66.1%的平均正确率；基於集合计算的概念分群演算法使用了知网做为撷取特徵词汇的知识库，透过知网取得词汇的概念，将具相同或相似概念的特徵词汇所属的句子分成同一群，补足词形分群演算法的不足，得到72.3%的平均正确率；基於义原距离的概念分群演算法则利用义原间的距离计算特徵概念的相似度，进一步改善了基於集合计算的概念分群演算法在相似度衡量的问题，得到81%的平均正确率，达到更好的分群效果。

这些限量版车型，功能团体和沙比利，乌木peghead覆盖，铬的硬件和将采用&35&周年制作的脖子之间镶嵌在第11和第12烦恼的。

In our model, we introduce an "appearance feature" to represent features of image patches around the lines, and then the appearance feature is used in a measurement that evaluates saliency of potential lines.

在模型中，我们引入了一个&表征特性&来描述位于图像上的边界线段周围区域的图像特性，然后这个特征被用来定义一个度量图像中线条显著程度的尺度。
