Struct ExtractionQualityMetrics 

pub struct ExtractionQualityMetrics {
    pub total: usize,
    pub duplicates: usize,
    pub duplication_rate: f64,
    pub noisy: usize,
    pub noise_rate: f64,
}

Lightweight extraction-quality diagnostics inspired by CORE-KG.

These are heuristics. They are useful for monitoring regressions and surfacing obvious quality problems (e.g., repeated identical nodes, garbage spans) but they are not “ground truth” correctness metrics.

Fields

total: usize

Total number of extracted entities.

duplicates: usize

Count of entities considered duplicates under conservative normalization.

duplication_rate: f64

Duplicate rate (duplicates / total).

noisy: usize

Count of entities considered “noisy” spans (punctuation-only, numeric-only, etc.).

noise_rate: f64

Noise rate (noisy / total).

Trait Implementations

impl Clone for ExtractionQualityMetrics

fn clone(&self) -> ExtractionQualityMetrics

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for ExtractionQualityMetrics

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for ExtractionQualityMetrics

fn default() -> ExtractionQualityMetrics

Returns the “default value” for a type.
