Keyword extraction involves identifying the most descriptive words in a document, allowing automatic categorisation and summarisation of large quantities of diverse textual data. Relying on the insight that real-world keyword detection often requires handling of diverse content, we propose a novel supervised keyword extraction approach based on the mixture of experts (MoE) technique. MoE uses a learnable routing sub-network to direct information to specialised experts, allowing them to specialize in distinct regions of the input space. SEKE, a mixture of Specialised Experts for supervised Keyword Extraction, uses DeBERTa as the backbone model and builds on the MoE framework, where experts attend to each token, by integrating it with a recurrent neural network (RNN), to allow successful extraction even on smaller corpora, where specialisation is harder due to lack of training data. The MoE framework also provides an insight into inner workings of individual experts, enhancing the explainability of the approach. We benchmark SEKE on multiple English datasets, achieving state-of-the-art performance compared to strong supervised and unsupervised baselines. Our analysis reveals that depending on data size and type, experts specialize in distinct syntactic and semantic components, such as punctuation, stopwords, parts-of-speech, or named entities.

The unmanned airstrike occurred in the Nangarhar Province of Afghanistan. Initial indications are that we killed the target,

White House correspondent Peter Doocy has the latest on Biden's response to the crisis in Afghanistan on'Special Report' The United States military has carried out a drone strike against an alleged ISIS-K "planner" following a suicide bombing in Kabul that killed 13 American soldiers and at least 70 Afghans. "U.S. military forces conducted an over-the-horizon counterterrorism operation today against an ISIS-K planner," U.S. Central Command Spokesman Captain Bill Urban told Fox News on Friday. "The unmanned airstrike occurred in the Nangarhar Province of Afghanistan. Initial indications are that we killed the target. We know of no civilian casualties."

The autonomous vehicle division of Google's parent company will start hauling cargo using self-driving trucks, capping a busy week for next-generation shipping technology. Waymo, the driverless vehicle unit of Alphabet, announced a pilot programme that will have self-driving big rigs transport cargo to the company's data centres in Georgia. Several companies are vying to dominate the nascent self-driving vehicle industry, believing the technology will reshape how humans and goods travel. Waymo has already extensively tested autonomous cars intended to ferry people around. "Now we're turning our attention to things as well", the company said in a blog post, noting that driverless trucks pose unique tech challenges.

Technology and automotive companies touting self-driving cars as the future of transportation may have some work to convince San Franciscans, who keep attacking the vehicles. A third of traffic collisions involving autonomous vehicles in 2018 so far featured humans physically confronting the cars, according to data released by California. In one case, a taxi driver exited his cab and slapped the front passenger window of a General Motors Cruise parked behind him. No one was hurt, though the car sustained a scratch. In another case, a pedestrian hurtled across an intersection despite a "do not walk" sign, shouting as he went, and rammed his body into a different Cruise's rear bumper.

Michelle Obama took an apparent swipe at Donald Trump's social media habits, saying she uses social media "like a grown-up". "How many kids do you know that the first thing that comes off the top of their head is the first thing they should express? It's like, 'Take a minute. Talk to your crew before you put that [out there] and then spell check and check the grammar,'" the former First Lady said during a panel in New York, according to People. While Ms Obama did not mention the President by name, Mr Trump is known for stream-of-consciousness bursts of tweets that periodically contain grammatical and spelling errors.

U.S. Special Forces killed the head of the Islamic State group in Afghanistan last month, officials confirmed Sunday. Abdul Hasib died in a joint Afghan-U.S. operation in Nangarhar province April 27, Reuters reported. Hasib, who had been leading the faction since predecessor Hafiz Saeed Khan died in a U.S. drone strike last year, was believed the architect of several high-profile attacks, including a March 8 attack on Kabul's main military hospital that left dozens of medical staff and patients dead. Afghan President Ashrab Ghani also has accused Hasib of ordering the beheading of local elders in front of their families and the kidnapping of women and girls, who were forced to marry ISIS fighters. Two U.S. Army Rangers also died in the attack that killed Hasib, part of an operation that included drone strikes that began in March along the border with Pakistan. Last month, the U.S. dropped "the mother of all bombs" on a network of caves, killing 94 fighters.

In the deadliest attack against Indian forces in more than a decade, militants sneaked into an army encampment in the disputed territory of Kashmir early Sunday and opened fire on sleeping soldiers, killing at least 17 and wounding dozens. The four assailants, who also threw grenades that caused tents and temporary shelters to catch fire at the army brigade headquarters at Uri, were killed in a gun battle with security forces that lasted six hours, authorities said. Indian officials blamed the Pakistan-based militant group Jaish-e-Mohammed for the attack, saying it had recovered weapons from the assailants that carried Pakistani markings. Lt. Gen. Ranbir Singh, the director of military operations, said he contacted his Pakistani counterpart to convey "serious concerns." Indian Home Minister Rajnath Singh was more pointed, saying on Twitter: "Pakistan is a terrorist state, and it should be identified and isolated as such."

WASHINGTON/PESHAWAR, PAKISTAN – The leader of the Islamic State group's branch in Afghanistan and Pakistan was killed in a U.S. drone strike on July 26, a Pentagon spokesman said on Friday after the Afghan ambassador to Pakistan announced the news to Reuters. The death of Hafiz Saeed Khan is a blow to efforts by the Islamic State -- also known as ISIS or Daesh -- to expand from its heartlands in Syria and Iraq into Afghanistan and Pakistan, which already are crowded with jihadi movements, including the Taliban and al-Qaida. It is the second U.S. killing of a prominent militant in the region in months. In May, a U.S. drone killed Afghan Taliban leader Mullah Akhtar Mansour in a strike in Pakistan. Despite that, Afghanistan's 15-year-old war grinds on with no clear victory in sight.
