Measuring without labels: a different approach to information extraction

This is post was originally published on the SpringerOpen blog. Information extraction (IE) is a broad area in both the natural language processing (NLP) and the Web communities. The main goal of IE is to extract useful information from raw documents and webpages. For example, given a product webpage, one might want to extract attributes like the name of the product, its date of production, price and seller. A few decades ago, such extractors were built painstakingly using rules. In the modern artificial intelligence (AI) community, IE is done using machine learning. Supervised machine learning methods take a training...

This dialogue often begins with broad philosophical, cultural, and religious concepts, but, when discussing virginity, invariably turns towards biology, specifically a tiny, membranous tissue at the external vaginal opening with no known biological function: the hymen. The hymen has gained outsized status as the arbiter of virginity. ©...

Yellow fever: The new urban and international epidemics

Yellow fever is a virus transmitted by mosquitoes. It is found in 29 countries of sub-Saharan Africa and 13 in South America, resulting in 200,000 cases and 30,000 deaths in endemic areas. Transmission often occurs when humans encroach jungle borders for work or leisure activities. But recently, urban outbreaks have led to the international transmission of yellow fever outside its usual boundaries. Although in 80–90% of cases, yellow fever is only a mild infection with symptoms of fever, headache, chills, muscle pain, fatigue, loss of appetite, nausea, and vomiting lasting for less than a week, for the remaining ~15%...
