Struct TPLinker 

pub struct TPLinker { /* private fields */ }

TPLinker backend for joint entity-relation extraction.

When the onnx feature is enabled and a model has been loaded, uses real neural handshaking matrix decoding. Otherwise falls back to a heuristic baseline using StackedNER + trigger matching.

Implementations

impl TPLinker

pub fn new() -> Result<TPLinker, Error>

Create a new TPLinker instance.

Attempts to load the ONNX model from the default cache directory. Falls back to heuristic mode if the model is not available.

pub fn with_thresholds( entity_threshold: f32, relation_threshold: f32, ) -> TPLinker

Create with custom thresholds.

pub fn from_local(dir: &Path) -> Result<TPLinker, Error>

Create from a local model directory (ONNX only).

pub fn is_neural(&self) -> bool

Whether this instance is using the neural ONNX backend.
