(Press-News.org) Imagine reading a long article or a thick legal contract and knowing, with confidence, exactly which lines prove that an event happened—or did not happen. That is now possible thanks to a research team at Soochow University. They have built a new neural network that not only determines if an event described in a document is real but also highlights the exact sentences that led it to that conclusion. In head-to-head comparisons with earlier approaches, this new model improved overall fact-checking accuracy by 2.5 points and exact-match accuracy by almost 5 points on a standard benchmark.
“We aimed to open the black box of AI decision-making,” says Prof. Zhong Qian, the lead researcher. “By showing exactly which sentences support our model’s verdict, we make its reasoning as clear as stepping through a well-explained proof.”
Why This Makes a Difference
In our fast-paced digital world, false or misleading claims can spread rapidly. Journalists racing to cover breaking stories need tools that do not simply raise a flag but also explain their reasoning. Legal teams reviewing lengthy contracts cannot afford to miss a single misleading clause. This model’s ability to pinpoint the precise text that supports—or contradicts—an event’s truth helps professionals across fields see exactly why a claim stands or falls. It is a step toward AI systems that feel less like inscrutable black boxes and more like transparent partners.
A Tool for Many Fields
This innovation goes far beyond the newsroom. In the media, it could slash the time needed to verify eyewitness accounts or viral online claims by highlighting the most telling sentences. In law, it could breeze through pages of dense text to mark where a statement is grounded in fact or where it may be speculative. Even scientists and developers of future AI systems will benefit from a clear example of how to strike a balance between accuracy and interpretability. In every case, the result is greater trust and faster, more reliable decision-making.
What the Tests Showed
When the team applied their model to an English corpus used by researchers worldwide, it achieved a factual-accuracy score of 66.9%—up from 64.4%—while exact matches rose to 42.9%, nearly five points higher than the previous best pipeline approach. The gains were most dramatic in cases involving speculative language or outright negatives—areas where earlier models often struggled. The model even maintained its edge when tested on a Chinese version of the same dataset, demonstrating its ability to adapt across languages.
How It Comes Together
At the heart of the new approach is a method of examining a document from multiple angles simultaneously. The system builds a web of connections among words, sentences, and special cues such as “not” or “perhaps.” It then homes in on the exact stretch of text that carries the weight of the truth decision. Finally, it blends those pinpointed clues with the overall story of the document to arrive at a final verdict. The result is both precise and coherent, with no loose ends.
This work appears in the June 2025 issue of Frontiers of Computer Science. The authors plan to share their code and detailed annotations, allowing others to build upon their outcomes. As AI becomes a crucial part of our daily lives, innovations like this one promise to keep machines honest, transparent, and valuable—whether we are checking the latest news, reviewing a contract, or simply reading for pleasure.

Efficient carbon integration of CO₂ in propane aromatization over acidic zeolites
2025-07-02
Aromatics, as extremely crucial basic chemicals in the modern industrial system, are widely used in many fields such as energy, medicine, materials and the daily chemical industry. However, the traditional petroleum-based production routes, such as naphtha cracking and catalytic reforming, are facing the dual pressures of tight petroleum resources and carbon emissions. Meanwhile, CO2, as a typical greenhouse gas, its efficient and value-added utilization offers dual benefits in both environment and economic development, but is limited by its thermodynamic stability, and there are still challenges in producing aromatics with high selectivity through hydrogenation pathways. Propane, as a major ...
FPGA-accelerated AI for demultiplexing multimode fiber towards next-generation communications
2025-07-02
With the exponential growth of global data traffic driven by AI, big-data analytics, and cloud computing, today’s single-mode fiber (SMF) networks are edging toward their Shannon-capacity limits. Space-division multiplexing (SDM) in multimode fiber (MMF) has emerged as a leading candidate for the next-generation bandwidth breakthrough because a single MMF can carry many orthogonal transverse modes in parallel. However, random mode coupling during propagation mixes these modes into complex speckle patterns, severely complicating signal recovery. Although conventional digital signal ...
Vitamin D3 nanoemulsion significantly improves core symptoms in children with autism: A clinical trial
2025-07-02
This study investigates the effectiveness of a vitamin D3-loaded nanoemulsion in improving the core symptoms of autism spectrum disorder (ASD) in children. Children with ASD often have low vitamin D3 levels, which are linked to delays in language development, adaptive behavior, and fine motor skills. While traditional vitamin D3 supplementation has shown mixed results in past studies, this research evaluates whether a nanoemulsion form—engineered to enhance absorption and bioavailability—might produce better outcomes.
Eighty children between the ages of 3 and 6 with diagnosed ASD were randomly assigned into two groups: one receiving the ...
Microfluidic point-of-care device accurately measures bilirubin in blood serum: A pilot study
2025-07-02
This pilot study evaluates a newly developed point-of-care (PoC) device designed to measure bilirubin levels in human blood serum using a microfluidic cartridge and optoelectronic sensing module. Accurate bilirubin measurement is critical for assessing liver function and diagnosing conditions such as jaundice and neonatal hyperbilirubinemia. Traditional laboratory methods are accurate but not suitable for rapid or resource-limited settings due to their complexity. The goal of this study was to determine if the new portable PoC device could deliver comparable accuracy and clinical utility.
Serum samples from 20 patients with bilirubin concentrations ranging ...
Amygdalin shows strong binding and stabilizing effects on HER2 receptor: A computational study for breast cancer therapy
2025-07-02
This study investigates the potential of amygdalin, a natural compound found in almonds, peaches, and apples, as a therapeutic agent for HER2-positive breast cancer. HER2 (human epidermal growth factor receptor 2) is overexpressed in a significant percentage of aggressive breast cancer cases and is associated with poor prognosis. The researchers aimed to explore whether amygdalin could effectively bind to and stabilize the HER2 protein, which could suppress its cancer-promoting activity.
To do this, the study employed a variety of computational tools. Molecular docking was used to determine how strongly amygdalin could bind to HER2, and results showed favorable binding ...

A unified bond stress–slip ...
Milky Way-like galaxy M83 consumes high-speed clouds
2025-07-02
Researchers discover high-velocity clouds in the nearby spiral galaxy M83. These clouds are moving at speeds significantly different to the galaxy’s overall speed of rotation. The findings suggest that these clouds likely originated outside the galaxy, offering new insights into how galaxies acquire fresh gas and sustain star formation over billions of years. This hints at how our own galaxy evolved and may evolve in the future.

Damage from smoke and respiratory viruses mitigated in mice via a common signaling pathway
2025-07-02
A rare cell in the lining of lungs is fundamental to the organwide response necessary to repair damage from toxins like those in wildfire smoke or respiratory viruses, Stanford Medicine researchers and their colleagues have found. A similar process occurs in the pancreas, where the cells, called neuroendocrine cells, initiate a biological cascade that protects insulin-producing pancreatic islet cells from damage.
Treating the airways of mice with an experimental drug that activates the repair pathway protected their airways from damage after infection with influenza or ...
