Target estimation method for a udio-visual recorders based on users´ operation history

This paper proposes a target estimation method based on users´ operation history in which the operation history is assumed to be based on the label-following strategy. The proposed method is applied for AV appliances, and the effectiveness of the method is assessed. A target function is estimated from the semantic similarity between the collection of words of the menu items and labels of remote controller buttons selected by the user. Experimental results show that the average rank of the estimated order of finding the target function from all the selection history data was 8.7.
