Advancements in natural language processing have revolutionized the way we can interact with digital information systems, such as databases, making them more accessible. However, challenges persist, especially when accuracy is critical, as in the biomedical domain. A key issue is the hallucination problem, where models generate information unsupported by the underlying data, potentially leading to dangerous misinformation. This paper presents a novel approach designed to bridge this gap by combining Large Language Models (LLM) and Knowledge Graphs (KG) to improve the accuracy and reliability of question-answering systems, on the example of a biomedical KG. Built on the LangChain framework, our method incorporates a query checker that ensures the syntactical and semantic validity of LLM-generated queries, which are then used to extract information from a Knowledge Graph, substantially reducing errors like hallucinations. We evaluated the overall performance using a new benchmark dataset of 50 biomedical questions, testing several LLMs, including GPT-4 Turbo and llama3:70b. Our results indicate that while GPT-4 Turbo outperforms other models in generating accurate queries, open-source models like llama3:70b show promise with appropriate prompt engineering. To make this approach accessible, a user-friendly web-based interface has been developed, allowing users to input natural language queries, view generated and corrected Cypher queries, and verify the resulting paths for accuracy. Overall, this hybrid approach effectively addresses common issues such as data gaps and hallucinations, offering a reliable and intuitive solution for question answering systems.

"Top Gun" producer Jerry Bruckheimer sees the overall benefit of artificial intelligence. "Anything that makes our lives easier that doesn't take jobs away from people that we work with every day is good for everybody. It gives them a better movie experience. We can make things look more real and things like that," he told Fox News Digital. However, he didn't see the technology eliminating important jobs in the industry.

Fox News Flash top headlines are here. Check out what's clicking on Foxnews.com. American technology is scoring big against Iran-backed threats in the Red Sea region, and it's bad news for China. You know the U.S. Navy destroyer USS Carney was in the news again Sunday, shooting down drones launched from Yemen's Houthi rebels against merchant shipping in the Red Sea. This crew has been taking out drones and missiles supplied by Iran for weeks now, and their tally is over two dozen destroyed so far.

Top Gun: Maverick has proven to be a massive success for Tom Cruise, Paramount Pictures, and everyone involved. If you've watched the movie by now, you'll probably agree with most of us that it's an excellent follow-up to the original film from 1986. What you might not know is that Val Kilmer's voice in the movie was brought to life with voice AI. When the original Top Gun was released in 1986, Val Kilmer and Tom Cruise's chemistry on-screen as Iceman and Maverick was an instant hit. Revisiting that story without Kilmer's Iceman would have been disappointing for many fans and even for Kilmer himself.

Maverick's next wingman could be a drone. In the movies, fighter pilots are depicted as highly trained military aviators with the skills and experience to defeat adversaries in thrilling aerial dogfights. New technologies, though, are set to redefine what it means to be a "Top Gun," as algorithms, data and machines take on a bigger role in the cockpit -- changes hinted at in "Top Gun: Maverick." "A lot of people talk about, you know, the way of the future, possibly taking the pilot out of the aircraft," said 1st Lt. Walker Gall, an F-35 pilot with the U.S. 48th Fighter Wing based at RAF Lakenheath in England. "That's definitely not something that any of us look forward to." "I'd like to keep my job as long as possible, but I mean, it's hard to argue with newer and newer technology," he said.

Tom Cruise and Val Kilmer are not the only stars of the hit movie Top Gun: Maverick. Artificial intelligence is right up alongside Maverick and Iceman to make the drama real and compelling for movie goers around the world. Top Gun: Maverick is the sequel to the 1986 iconic movie Top Gun, in which Cruise and Kilmer played rival students at the U.S. Navy's Fighter Weapons School. Between 1986 and 2022, when Top Gun: Maverick was released both Cruise and Kilmer enjoyed high successful film careers. But unfortunately, Kilmer lost the use of his voice after a battle with throat cancer.

After first starring as Lieutenant Tom "Iceman" Kazansky in the 1986 film "Top Gun," Val Kilmer made his triumphant return, 36 years later, in the sequel "Top Gun: Maverick." In the 2022 film, he now plays an admiral. Kilmer, 62, was diagnosed with throat cancer in 2014 according to The New York Times Magazine. After going through several treatments, including a tracheotomy, he lost his voice, the outlet reports. Kilmer publicly confirmed his diagnosis in 2017 after denying reports of his illness.

Scientists helped Kilmer reprise his iconic role as 'Iceman' after he suffered irreparable damage to his voice through throat cancer in 2014.

On July 3rd, Tom Cruise will be sixty years old. The fact that he does not look it, at all, even in IMAX closeups so tight you can study the grain of his tooth enamel, adds a note of cognitive dissonance to "Top Gun: Maverick," the long-aborning sequel in which he's called back to mentor a squad of younger stick-jockeys who address him as Pops and Old-Timer until he wins their respect in the air. Even for a physical performer like Cruise, sixty is no longer an expiration date. Mick Jagger blew by that milestone in 2003, as did Sylvester Stallone in 2006, and, thanks presumably to healthy habits and/or medical technology dreamt of only by science fiction, they're both still out there, doing a version of the kind of thing they've always done. But the level of performance expected of a Rolling Stone or an Expendable is one thing, and the work that Tom Cruise appears to demand of himself is something else entirely.
