LinkBERT calculates token-level probabilities through a dedicated local microservice running on loopback port 8006, isolating the 3.3 GB transformer model from the main web process. For input text up to 20,000 characters, the service returns synchronized word tokens, exact character offset spans, and float probabilities ranging from 0.0 to 1.0. Because the entire array of word probabilities is delivered in a single inference request, the user interface can dynamically update confidence threshold sliders in real time without triggering additional server round trips. This enables instant visual grouping of high-scoring adjacent words into natural, candidate anchor phrases directly in the browser.
