摘要:

知识库是人工智能的一个重要方面。KB构造面临的一个重大挑战是它包含许多噪声,这妨碍了其有效使用。尽管已经提出了一些知识库清洗算法,但它们关注的是知识图谱的结构,而忽略了概念之间的关系,这可能有助于发现知识库中的错误关系。受此启发,我们衡量的关系,两个概念之间的距离,其相应的实例和检测的冲突概念集的交集内的错误。为了高效和有效的知识库清洗,我们首先应用基于距离的模型来确定冲突的概念集使用两种不同的方法。然后,我们提出并分析了几种算法如何检测和修复错误的基础上,我们使用哈希方法的一种有效的方法来计算距离。实验结果表明,该方法能够有效地清洗知识库。

英文摘要:

Knowledge base (KB) is an important aspect in artificial intelligence. One significant challenge faced by KB construction is that it contains many noises, which prevents its effective usage. Even though some KB cleansing algorithms have been proposed, they focus on the structure of the knowledge graph and neglect the relation between the concepts, which could be helpful to discover wrong relations in KB. Motived by this, we measure the relation of two concepts by the distance between their corresponding instances and detect errors within the intersection of the conflicting concept sets. For efficient and effective knowledge base cleansing, we first apply a distance-based Model to determine the conflicting concept sets using two different methods. Then, we propose and analyze several algorithms on how to detect and repairing the errors based on our model, where we use hash method for an efficient way to calculate distance. Experimental results demonstrate that the proposed approaches could cleanse the knowledge bases efficiently and effectively.
