In recent years the technological world has grown by incorporating billions of small sensing devices, collecting and sharing real-world information. As the number of such devices grows, it becomes increasingly difficult to manage all these new information sources. There is no uniform way to share, process and understand context information. In previous publications we discussed efficient ways to organize...
Automatic annotating images by equipment is of great interest as it meets one's common need for retrieving image content. Usually image content description with keywords is regarded as a visual-word correlation process. However, in view of the viewer's psychology, image to words is a kind of cognition process, which depends more on the experience for one to understand what's in an image. In this paper,...
Latent Dirichlet allocation (LDA) has been widely used for analyzing large text corpora. In this paper we propose the topic-weak-correlated LDA (TWC-LDA) for topic modeling, which constrains different topics to be weak-correlated. This is technically achieved by placing a special prior over the topic-word distributions. Reducing the overlapping between the topic-word distributions makes the learned...
The calculation of semantic similarity is a key point in Chinese information processing. This paper presents a new method for calculating semantic similarity between two words. Different from previous methods, this paper focuses on the perspective of connotations, trying to highlight the essential attributes of words by which we can get the similarity value in words' conceptual level. Firstly, we...
