Most traditional text clustering methods are based on “bag of words” representation. However, since topics in closed captions are very short, it is difficult to supply enough “bag of words” information. In this paper, we present a new approach for topic clustering on closed captions. First, we clustered one-year closed captions manually, and discovered that topics categorized into “accidents” or “disasters” shows particular cluster- and time- distributions. Therefore we proposed un-supervised clustering method using temporal information adding to conventional word vector distance. Furthermore, the accuracy was improved by changing the linkage criteria as the clustering process progresses. Our experimental results show the effectiveness of combination of time and word information. |
