Good Neighbors Make Good Senses: Exploiting Distributional Similarity for Unsupervised WSD
We present an automatic method for senselabeling of text in an unsupervised manner. The method makes use of distributionally similar words to derive an automatically labeled training set, which is then used to train a standard supervised classifier for distinguishing word senses. Experimental results on the Senseval-2 and Senseval-3 datasets show that our approach yields significant improvement...

By employing a difference-in-difference Poisson panel regression framework, as well as group-based trajectory analyses, these authors examine the High ...
متن کاملWater filling may not good neighbors make
Abstract— Consider a wireless system with multiple and independent user-base pairings over some region. Each user tries to greedily optimize its performance, and eventually a simultaneous water-filling fixed point is reached. Here we seek to analytically understand properties of different water-filling fixed points. In so doing we show that water-filling alone does not generally result in optim...
متن کاملGood Fences Make Good Neighbors: a Longitudinal Analysis of an Industry Self-regulatory Institution
We extend theories of self-regulation of physical commons to analyze self-regulation of intangible commons in modern industry. We posit that when the action of one firm can cause “spillover” harm to others, firms share a type of commons. We theorize that the need to protect this commons can motivate the formation of a self-regulatory institution. Using data from the U.S. chemical industry, we f...
متن کاملGood Fences Make Good Neighbors: Values of Digital Objects in FarmVille2
This paper describes the findings of a textual and structural analysis of the free-to-play social networking game FarmVille 2 (FV2) with a focus on the values (social, economic, etc.) available to players for digital objects within the game. FV2 is purportedly a social game, which might suggest that findings regarding the social values of objects from the study of material culture could play ou...
