Knowledge map construction for question and answer archives
作者：
Highlights：
• A novel knowledge map for question and answer archives is constructed.
• A novel growing hierarchical 2-dimensional self-organizing map is proposed.
• Extracting typical Q&A pairs is proposed to help users quickly grasp main contents.
• A merging mechanism is proposed during vertical expansion to avoid parsing.
• Experimental results show that the knowledge map is feasible and performs well.
