Human-Level Performance on Word Analogy Questions by Latent Relational Analysis
Peter D. Turney
This paper introduces Latent Relational Analysis (LRA), a method for measuring relational similarity. LRA has potential applications in many areas, including information extraction…
Word Sense Disambiguation by Web Mining for Word Co-occurrence Probabilities
Peter D. Turney
This paper describes the National Research Council (NRC) Word Sense Disambiguation (WSD) system, as applied to the English Lexical Sample (ELS) task in Senseval-3. The NRC system a…
Destruction of Stellar Disks by Photoevaporation
D. Johnstone, I. Matsuyama, I. G. McCarthy +1
Photoevaporation may provide an explanation for the short lifetimes of disks around young stars. With the exception of neutral oxygen lines, the observed low-velocity forbidden lin…
Molecular electronics exploiting sharp structure in the electrode density-of-states. Negative differential resistance and Resonant Tunneling in a poled molecular layer on Al/LiF electrodes
Z. H. Lu, M. W. C. Dharma-wardana, R. S. Khangura +2
Density-functional calculations are used to clarify the role of an ultrathin LiF layer on Al electrodes used in molecular electronics. The LiF layer creates a sharp density of stat…
