題名: | Mining Temporal Co-orientation Pattern from Spatio-temporal Databases | 作者: | Shan, Man-kwan;Wei, Ling-yin 沈錳坤 |

In this paper, we introduce temporal co-orientation pattern mining which is the problem of temporal aspects of spatial co-orientation patterns. A temporal co- orientation pattern represents how spatial co-orientation patterns change over time. Temporal co-orientation pattern mining is useful for discovering tactics from play sequences of sports video data, because the most tactic patterns of basketball competition are constituted of such spatial co-orientation patterns in time order. We propose the three-stage approach, which transforms the problem into sequential pattern mining, for mining temporal co-orientation patterns. We experimentally evaluate the performance of the proposed algorithm and analysis the effect of these stages. | 關聯: | Pacific-Asia Conference on Knowledge Discovery and Data Mining - PAKDD , pp. 895-903 | 資料類型: | article | DOI: | http://dx.doi.org/10.1007/978-3-540-71701-0_100 |
