... (CLUTO toolkit) 3 is used to divide it into different cohesive subtypes, each of which only contains the entities of the same background. For instance, the Air entities will be divided into ... entity. After establishing the vector space model (VSM) for each entity mention of the type, we adopt a clustering toolkit (CLUTO) to further divide the mentions into different subtypes. F...
