中文摘要 | 近年來,專利資訊的數量呈現明顯的增長,然而企業基於專利策略考量,在提出專利申請文件時,有時會迴避關鍵字使用,或者搜尋專利不在檢索者預期的分類號中等等因素,這都可能使得研發人員無法正確地檢索到真正相關的專利。藉由專利共被引用及叢集分析可以有效地將相關專利予以群集一起,然而一般專利共被引用分析並未考慮專利年齡,因而失去平等比較的基準。本研究在考慮專利年齡之時間差異下,結合專利共被引用網路及叢集分析,將相關性高的專利予以叢集歸類,其研究結果可作為專利檢索的輔助工具,進而提供企業專利分析之參考依據。 |
英文摘要 | Patents are rich sources of technical and commercial information. Patent co-citation analysis (PCA) has been widely used in bibliometrics as an analytical method in analyzing the intellectual structure of patents studies. However, such analysis method does not consider the difference of age of patents. In this paper, we propose a mining process to cluster those similar patents with time-variant of co-citation analysis. The mining process uses agglomerative hierarchical clustering (AHC) as the mining technique for patent clustering. The clustering results can help companies as a map for tracking the technology trajectory. |
