On January 26th, ALI HEALTH's medical AI application "Hydrogen Ion" received a significant version update, introducing a new "Dynamic Evidence Localization" feature. This function can precisely pinpoint the specific sentences in source texts that directly support a given viewpoint, while simultaneously verifying their timeliness, authority, and logical consistency.

In clinical and research decision-making, a doctor's trust in AI is never just about "whether there is a source," but rather "whether this source remains valid at this moment." The core of the Dynamic Evidence Localization feature lies in upgrading the industry-standard "static citation" to an evolvable "living evidence." Traditional solutions rely on static knowledge bases, using keyword matching to retrieve a relevant paragraph, which only addresses the spatial positioning of "where it comes from." However, they fail to assess if the content is outdated, if the evidence is reliable, and struggle to discern whether the basis remains valid and credible.

Hydrogen Ion systematically addresses this industry challenge through its proprietary "Three-Dimensional Evidence-Based Architecture" technological framework. For its intelligent Q&A function, it is the first to integrate timeliness (When) and authority (Quality) into the citation logic. By performing daily tracking and intelligent filtering of global guidelines and literature, it ensures that every answer is consistently based on the latest and most reliable medical evidence.

For example, when a user searches Hydrogen Ion for "What are the primary endpoint data (ORR, PFS, OS) for the Phase II clinical trial of erdafitinib?", the system not only provides structured medical conclusions and analysis but also labels each conclusion with a citation tag. Clicking the tag allows the user to view the original literature cited for that conclusion and the specific sentences supporting it. This enables seamless traceability from conclusion to evidence, ensuring every citation is verifiable and trustworthy.

"The core objective of this technology is to make doctors truly dare to believe and dare to use it," according to a product lead. "The system updates and filters global authoritative guidelines and literature on a daily basis, ensuring the presented content always falls within the valid window of current medical consensus. Simultaneously, we apply authority weighting to billions of global data points to reduce interference from low-quality information at the source. Ultimately, what is presented to the user is not a coarse-grained paragraph citation, but a precise extraction of the key sentences that support the conclusion."
