As the number of systems which offer annotations on digital documents increases, robust anchoring of annotations is a key challenge. It is especially important if the annotator lacks write-access to the document being annotated. For example, if someone makes an annotation on a web page today and the web page changes tomorrow, what happens to the annotation? One approach is simply to “orphan” th...

This paper introduces gain-cost classi…cation matrix for targeting customer groups. A real life application was realized on a customer database of CCF Bank containing more than 400,000 instances. Results shows that scoring is almost insensitive to di¤erent cost-gain hypothesis; on the other hand, the optimal targeted group size and the expected global bene…t rely to cost-gain hypothesis. Keywor...

To spot keywords on handwritten documents, we present a hybrid keyword spotting system, based on features extracted with Convolutional Deep Belief Networks and using Dynamic Time Warping for word scoring. Features are learned from word images, in an unsupervised manner, using a sliding window to extract horizontal patches. For two single writer historical data sets, it is shown that the propose...
