摘要 随着网络技术不断飞速发展,人们的信息需求也随之增长。用户不再满足基于关键字的检索,而是希望网络能够实现以用户所关心的信息为中心、以用户需求为导向,将所有与中心相关的信息全部汇聚起来,也就是实现语义关联聚焦服务。所以针对语义关联聚焦服务需求,提出构建一种包含语义关联关系的语义覆盖网的方法,即首先将网络节点按照语义相似度组织成聚类,然后计算节点的语义关联度,最后根据语义关联度在聚类之间添加关联链接,最终形成各网络节点的关联语义覆盖网络。 随着网络技术不断飞速发展,人们的信息需求也随之增长。用户不再满足基于关键字的检索,而是希望网络能够实现以用户所关心的信息为中心、以用户需求为导向,将所有与中心相关的信息全部汇聚起来,也就是实现语义关联聚焦服务。所以针对语义关联聚焦服务需求,提出构建一种包含语义关联关系的语义覆盖网的方法,即首先将网络节点按照语义相似度组织成聚类,然后计算节点的语义关联度,最后根据语义关联度在聚类之间添加关联链接,最终形成各网络节点的关联语义覆盖网络。
