This paper describes a methodology to provide robots with capability of integrative multimedia understanding centered in natural language understanding (NLU) and its recent application to cross-media operation between linguistic and pictorial representations such as town maps and animations of robotic action. The core of the methodology is based on the mental image directed semantic theory (MIDST)...
Recently, in the field of artificial intelligence (AI), special attention has been paid to deep neural networks (DNNs) because of remarkable performance in various pattern-recognition tasks, especially in visual classification problems. However, interesting differences as well have been pointed out between human vision and current DNNs arousing questions about the generality of DNN computer vision,...
When people refer to physical locations in their casual communication, they would employ intuitive spatial relations such as ‘along’, ‘across’ and ‘between’ rather than the global coordinates. These word concepts seem to be human cognitive products, namely mental imagery, about the physical environment. This paper describes an attempt to provide robots with capability of natural language understanding...
The terminology ‘natural language’ surely reminds most people of any ordinary human language that they use to communicate with each other, but as well it alludes to the most convenient way by which ordinary non-expert people can intuitively interact with artifacts such as robots. Therefore, without any doubt, the technology of Natural Language Understanding (NLU) plays a key role at such intuitive...
Natural language can be the most convenient means for ordinary people at their intuitive interaction with home robots and among all its sublanguages, the spatiotemporal (or 4D) language is expected to be the most important when both the entities communicate each other in their casual scenes. As easily imagined, it is quite ordinary for people to understand a 4D expression with the mental image of...
Nowadays, location measurement systems like GPS are widely utilized to acquire locations in the global coordinates system and have already been applied to location-aware systems of practical use such as vehicle-navigation systems. It is, however, not very common for people to refer to these coordinates but intuitive spatial relations such as ‘at’, ‘around’, ‘along’, etc. in their casual communication...
