Experiments in Graph-Based Semi-Supervised Learning Methods for Class-Instance Acquisition
Graph-based semi-supervised learning (SSL) algorithms have been successfully used to extract class-instance pairs from large unstructured and structured text collections. However,...

Relative Performance of Geometric Search Algorithms for Interpolating Unstructured Mesh Data
Abstract. Interpolation of field data from unstructured meshes requires the potentially expensive identification of the finite element or volume within which the interpolating poin...

The Half-Edge Tree: A Compact Data Structure for Level-of-Detail Tetrahedral Meshes
We propose a new data structure for the compact encoding of a Level-Of-Detail (LOD) model of a threedimensional scalar field based on unstructured tetrahedral meshes. Such data s...
