Abstract |
This paper discusses the automatic concept hierarchy generation process for specific knowledge network. Traditional concept hierarchy generation uses hierarchical clustering to group similar terms, but the result hierarchy is usually not satisfactory for human recognition. Human-provided knowledge network presents strong semantic features, but the generation process is both labor-intensive and inconsistent in a large scale hierarchy. The method proposed in this paper combines the results of specific knowledge network generation and automatic concept hierarchy generation to produce a human-readable, semantic-oriented hierarchy. This generation process can efficiently reduce the efforts of manual classification, an exhausting task for human beings. An evaluation method is also proposed in this paper to verify the quality of the result hierarchy.
