Evaluation Protocol

This paper analyzes the varied performance of Matrix Factorization (MF) on the related tasks of relation extraction and knowledge-base completion, which have been unified recently into a single framework of knowledge-base inference (KBI) [Toutanova et al., 2015]. We first propose a new evaluation protocol that makes comparisons between MF and Tensor Factorization (TF) models fair. We find that this results in a steep drop in MF performance. Our analysis attributes this to the high out-of-vocabulary (OOV) rate of entity pairs in test folds of commonly-used datasets. To alleviate this issue, we propose three extensions to MF. Our best model is a TF-augmented MF model. This hybrid model is robust and obtains strong results across various KBI datasets.

Today, six out of ten Americans describe themselves as "active" environmentalists or as "sympathetic" to the movement's concerns. The movement, in turn, reflects this millions-strong support in its diversity, encompassing a wide spectrum of causes, groups, and sometimes conflicting special interests. For far-sighted activists and policy makers, the question is how this diversity affects the ability to achieve key goals in the battle against pollution, erosion, and out-of-control growth. This insightful book offers an overview of the movement -- its past as well as its present -- and issues the most persuasive call yet for a unified approach to solving environmental problems. Focusing on examples from resource use, pollution control, protection of species and habitats, and land use, the author shows how the dynamics of diversity have actually hindered environmentalists in the past, but also how a convergence of these interests around forward-looking policies can be effected, despite variance in value systems espoused. The book is thus not only an assessment of today's movement, but a blueprint for action that can help pull together many different concerns under a common banner. Anyone interested in environmental issues and active approaches to their solution will find the author's observations both astute and creative.
