This paper argues that a formal ontology (in our case a description logic knowledge base) should be created in a linguistically motivated way so that it can be queried easily by non-specialists. This can best be achieved by using a strict naming convention that is based on those linguistic expressions that occur in the application domain for which the ontology will be created. We will see that ...

In this article, we describe a number of indexing experiments based on indexing terms other than simple keywords. These experiments were conducted as one step in validating a linguistically-motivated indexing model. The problem is important but not new. What is new in this approach is the variety of schemes evaluated. It is important since it should not only help to overcome the well-known prob...

Linguistic knowledge plays an important role on phrase movement in statistical machine translation. To efficiently incorporate linguistic knowledge into phrase reordering, we propose a new approach: Linguistically Annotated Reordering (LAR). In LAR, we build hard hierarchical skeletons and inject soft linguistic knowledge from source parse trees to nodes of hard skeletons during translation. Th...

We use optical flow to extract reliable kinematics from video for motions of the head, face, torso, and hands during speech and musical performance. Unlike dotand markerbased measures, these markerless measures are non-invasive and require no a priori specification of measurement locations. Reliability is compared with marker tracking data and the method’s utility is demonstrated for data from ...
