Most coreference resolution models determine
if two mentions are coreferent using a single
function over a set of constraints or features.
This approach can lead to incorrect decisions
as lower precision features often overwhelm
the smaller number of high precision ones. To
overcome this problem, we propose a simple
coreference architecture based on a sieve that
applies tiers of deterministic coreference models
one at a time from highest to lowest precision.
Each tier builds on the previous tier’s entity cluster output. Further, our model propagates global information by sharing attributes (e.g., gender and number) across mentions in the same cluster. This cautious sieve guarantees that stronger features are given precedence over weaker ones and that each decision is made using all of the information available
at the time. The framework is highly modular: new coreference modules can be plugged in without any change to the other modules. In spite of its simplicity, our approach outperforms many state-of-the-art supervised and unsupervised models on several
standard corpora. This suggests that sieve based approaches could be applied to other NLP tasks.

Unlike most accounts of the origins of Silicon Valley, this essay insists that the valley today is rooted in the Gold Rush, and only through understanding this can scholars fully comprehend the roots of the innovation process that so characterizes the region today. The Gold Rush began a long gestation period in the region’s technical sciences that, with its physical, economic and geographic characteristics, comprised a petri dish in which innovations flourished. Early on communities of interest emerged among the original Argonauts around hydraulic engineering and among later adventurers around hydroelectric power, electric-power transmission, radio technology and microwave electronics. Over the years their members included mechanics, inventors, engineers, academics and entrepreneurs, and they found like-minded souls in San Francisco Bay Area technical and scientific organizations, social clubs and educational institutions, where they all overlapped with each other and created the foundations for the modern Silicon Valley.

Documentos de archivo, noticias en prensa y retratos pictó-ricos y fotográficos permiten reconstruir el origen y el singular devenir histórico del aderezo de diamantes y esmeraldas fabricado en 1862 por Félix Samper para la reina Isabel II, cuya magnificencia fue elogiada y premiada en la época.

Many policies governing biobanks revolve around ownership and control of the materials and information in them. Those who manage biobanks may be tempted to seek the broadest legal rights possible over material and data. However, we suggest that even if ownership and control were clearly defined by the law and readily obtained by biobanks, how legal rights are used in practice matters as much or more than the rules for ownership. We draw lessons from the stories of genetic testing for Canavan disease and inherited breast and ovarian cancers. In both cases, the use or assertion of legal rights led to preventable controversy and suboptimal outcomes. The attempt to acquire and exercise intellectual property rights antagonized and alienated stakeholders, whom we define broadly to include the donors, patients, doctors, research institutions, health care providers, governments, and citizens with an interest in research and its outcomes. By analogy, even if biobanks could acquire expansive ...
