From reproductive rights to climate change to Big Tech, The Independent is on the ground when the story is developing. Whether it's investigating the financials of Elon Musk's pro-Trump PAC or producing our latest documentary, 'The A Word', which shines a light on the American women fighting for reproductive rights, we know how important it is to parse out the facts from the messaging.
At such a critical moment in US history, we need reporters on the ground. Your donation allows us to keep sending journalists to speak to both sides of the story.
The Independent is trusted by Americans across the entire political spectrum. And unlike many other quality news outlets, we choose not to lock Americans out of our reporting and analysis with paywalls. We believe quality journalism should be available to everyone, paid for by those who can afford it.
Your support makes all the difference.Artificial intelligence researchers at IBM have introduced a major upgrade to the famed Watson computer, allowing it to understand idioms and colloquialisms for the first time.
IBM says the update makes it the first commercial AI system capable of identifying, understanding and analysing some of the most challenging aspects of the English language.
Phrases like "hardly helpful" and "hot under the collar" are tricky for algorithms to spot, meaning AI is unable to debate complex topics or have nuanced conversations with humans.
"Language is a tool for expressing thought and opinion, as much as it is a tool for information," said Rob Thomas, a general manager at IBM Data and AI.
"This is why we believe that advancing our ability to capture, analyse, and understand more from language with NLP will help transform how businesses utilise their intellectual capital that is codified in data."
IBM announced the advancement as part of a new suite of Watson technologies focussed on Natural Language Processing (NLP), which will be implemented from its Project Debater AI system.
It marks the first commercialisation of key NLP capabilities and will mean Watson is "the only AI system capable of debating humans on complex topics," according to IBM.
The new "advanced sentiment analysis" feature will mean AI will not get tripped up over phrases like "I feel over the moon," instead understanding through context that a person is excited.
This new level of understanding will have immediate use in areas such as customer care, where the frequent use of casual language has made accurate understanding, classification and fine-grained analysis difficult.
IBM's Watson rose to prominence in 2011 when it took on and defeated human champions at the US game show Jeopardy!, making it the first computer capable of understanding the unique question-answer format used in the popular show.
Watson has since been used in everything from lung cancer treatment, to weather forecasting.
