实体链接杂记

单实体链接，打分排序模型

源文档AFP_ENG_20090605.036内容：



文档AFP_ENG_20090605.036里有15个待链接实体。



15个待链接实体中，其中有很多同名的，去重过后只有9个待链接实体：



在同一篇文章内，进行待链接实体扩展，扩展如下：

Brown------扩展为--------Gordon Brown

Johnson------扩展为--------Alan Johnson

扩展之后，剩下的待链接实体还有7个：



待链接实体基于文档，进行实体扩展后，可以减少待链接实体

候选集生成：

①字符串匹配查找--------------分数1----------最小编辑距离----

Gordon Brown    2个

Alan Johnson    2个

Sky News    7个

Jacqui Smith    1个

Labour     119个

British   1081个，并且字符匹配找不到答案，一般的做法是基于经验知识，构建同义词字典。所以Britsh可以等价于United Kingdom  United Kingdom在知识库在字符匹配查找可找到272个

LONDON   1114个


②语义查找--------------分数2-----------余弦相似度----

[if !supportLists]1) [endif]构建同义词字典的方法

British   1081个，并且字符匹配找不到答案，一般的做法是基于经验知识，构建同义词字典。所以Britsh可以等价于United Kingdom  United Kingdom在知识库在字符匹配查找可找到272个

2)词向量的方法



假设通过最小编辑距离、词向量余弦相似度等方法，每种方法设定一个阈值，筛选或加入一部分实体进来。（那两篇CNN的论文只对能链接上知识库的实体进行了实验，对于NIL空实体没有考虑，所以保证了每个待链接实体都生成30个候选实体）


假设每个实体保证5个候选集

保留名词的，词袋子相似度计算，使用注意力机制模型，词袋的维度会非常小，且针对每一篇文章有不同的词袋子


关系可以表示一个实体，在哪个关系数量级上，就足以区分出实体与实体之间的区别？？？？假定10个关系


共有的关系都要保留，因为虽然都有这种关系，但是关系的值可能是不一样的，这样就具有消歧作用。且与其他实体构成关系的关系，也要保留。关系留足10个即可。剩余的关系只用关系词来代表这个实体，因为h+r=t，头实体+关系已经可以表示尾实体了。
