Co—word Analysis Using Original Occurrence Matrices

摘要：

In previous studies,co-occurrence matrices are widely used.In our approach,we propose to use original occurrence matrices directly in co-word analysis,instead of using co-occurrence matrices which are considered to contain less information as they can be derived from the original matrices.Our result shows that the original occurrence matrices perform well in co-word analysis.
