This paper proposes a first attempt to include real semantic information into the process of handwriting recognition. We take advantage of the fact that the main topic of handwritten notes is often known beforehand like in annotation or reviewing tasks. Using state-of-the-art technologies from the knowledge management research area it is possible to store a semantic representation of the user’s knowledge in a Personal Information Model (PIMO). This PIMO stores the relations between semantic concepts and documents on the computer. In this paper we extract texts from related documents and concepts of the PIMO. The vocabulary of these texts is then used to aid the recognizer. In our multi-writer experiments, a significant improvement of the recognition accuracy by 8% on the text line level has been achieved.
