Table 3: Information of elements in the requirement mapping model. Figure 3: Assessment results of contribution rates. According to the assessment process of node importance in Section 3.3, the eigenvector centrality vector of the sub-network in the article layer \(x\) was calculated. Then, the authors assigned the values of two diffusion strength factors \(\alpha=\beta=1\) and integrated the adjacency matrix of the universal citation network \(A^{u}\). Finally, the assessment results were computed with the parameter conditions of \(s=0.85\) and \(k=100\) using the proposed algorithm. The top 10 articles and patents with the highest importance values are displayed in Table 4. The nodes with higher scores in knowledge diffusion analysis can be considered as innovation sources and the knowledge chunks which contain more innovation sources should be paid more attention in assessing development potential [18].
