| Abstract(in English) | In this paper, we propose Web video search re-ranking using tag vector. In the proposed method, we first construct a graph whose nodes and edges respectively correspond to user’s select videos and their similarities. Next, we obtain a re-ranking list by evaluating relevance of each video from the structure of the graph. In particular, we focus on the fact that multiple tags are used to represent video content. Specifically, by vectorizing multiple tags associated with videos based on the Word2Vec algorithm, we calculate the new tag feature vector. Then, we formulate the re-ranking process as the optimization problem whose regularization terms measure the relevance from both the video and tag features. Experimental results on a real-word which contains multiple word sense show the effectiveness of the proposed method. |
