3.4.5 Refining keyword clusters The number of keywords in each keyword cluster is unequal. In the document clustering phase, a keyword cluster with more keywords clusters more documents.
Therefore, not only do the meanings of the keywords in the
keyword clusters affect the results of document clustering,
but the sizes of the keyword clusters also affect the
accuracy. Hence, a criterion is required for refining the
keyword clusters. The component weight of the keyword clusters is
applied to eliminate loosely intra-connected keywords
from the keyword clusters. The component weight is given
by CW = CD(G)*AS(G), where CD(G) denotes the
connected density and AS(G) represents the average
strength of a keyword cluster. The connected density is
computed as ?, where |E(G)| denotes the number of edges in the keyword cluster, and |V(G)| denotes the number of vertices in the keyword cluster. The average strength of each cluster is estimated to

3.4.5 重新寻找关键词的组件。
在每一关键词组件的关键词数目并不相等。在成组句子的文件中,带有更多关键词的关键词祖,组合成更多的文件。因此,在关键词组件内的关键词的意义,不仅影响组建文件的结果,关键词组件的尺寸也影响精度。因而,重新寻找关键词的组件,就要求一判别规范。关键词组件的部件重量,是用来粗略估计从关键词组件来的内部联接的关键词。部件重量有下式给出:CW=CD(G)*AS(G);式中,CD(G) 表示联接密度;AS(G)代表关键词组件的平均长度。(待译)
