Research on HowNet based on formal concept analysis and concept similarity
知网的形式概念分析及概念相似度研究

A formal concept lattice was implemented which based on HowNet through mapping the concept, sememe and the relationship in HowNet into formal context. On the one hand, the formal concept lattice as a representation transformed all the conceptual relationship in HowNet. In other words, from any node of the lattice, various kinds of related knowledge were accessible. Thus it provided much convenience to information retrieval and knowledge reasoning. On the other hand, a method of calculating the concept similarity was proposed by analyzing the formal concept lattice, which had overcome the some shortcomings of former algorithms and been proved to be effective when applied to analyze speech acts of collaborative learning in experimental result.
