Abstract: This paper presents a novel approach for web video categorization byleveraging Wikipedia categories WikiCs and open resources describing the samecontent as the video, i.e., content-duplicated open resources CDORs. Notethat current approaches only col-lect CDORs within one or a few media forms andignore CDORs of other forms. We explore all these resources by utilizing WikiCsand commercial search engines. Given a web video, its discrimin-ative Wikipediaconcepts are first identified and classified. Then a textual query isconstructed and from which CDORs are collected. Based on these CDORs, wepropose to categorize web videos in the space spanned by WikiCs rather thanthat spanned by raw tags. Experimental results demonstrate the effectiveness ofboth the proposed CDOR collection method and the WikiC voting catego-rizationalgorithm. In addition, the categorization model built based on both WikiCs andCDORs achieves better performance compared with the models built based on onlyone of them as well as state-of-the-art approach.
