This paper presents a method to identify the topics of documents based on Wikipedia category network. It is to improve the method previously proposed by Schonhofen by taking into account the weights of words in hyperlink texts in Wikipedia articles. The experiments on computing and team sport domains have been carried out and showed that our proposed method outperforms the Schonhofen's one.
We present a set of techniques to perform in-situ refinements on simple geo-referenced models using mobile augmented reality systems. The refinements include affine transformations to the model and surface feature additions, including high detail concave and convex features. The techniques employ pinch gloves and a single-point laser rangefinder augmented with an orientation sensor as input devices...
This paper explores how a wearable computer with an augmented reality interface can provide real time contextual interactions, based on location aware Web 2.0 social network information.
We present a design and implementation of an in-situation menu system for loading and visualising 3D models in a physical world context. The menu system uses 3D objects as menu items, and the whole menu is placed within the context of the augmented environment. The use of 3D objects supports the visualisation and placement of 3D models into the augmented world. The menu system employs techniques for...
The accuracy of the inverse solution that finds the spatial location of the generating sources from averaged scalp-recorded event related potentials (ERPs) relies on assumptions about the ERP signals and the sources. We provide evidence that using independent component analysis (ICA) as a signal decomposition filter prior to applying the inverse solution reveals sources that cannot be detected by...
The sialomucin CD34 is expressed on human and mouse hematopoietic stem cells and is used as an important marker for isolating the hematopoietic stem/progenitor cells. The involvement of hepatic stem cells in liver regeneration under certain conditions in adult rats is now well supported. The objective of the present research was to explore the idea that CD34 might also be expressed on hepatic stem...
