Struct SemanticBoost

pub struct SemanticBoost {
    pub distance_factor: f32,
    pub phrase: String,
}

SemanticBoost : Distance phrase is useful for moving the embedding vector of the chunk in the direction of the distance phrase. I.e. you can push a chunk with a chunk_html of "iphone" 25% closer to the term "flagship" by using the distance phrase "flagship" and a distance factor of 0.25. Conceptually it’s drawing a line (euclidean/L2 distance) between the vector for the innerText of the chunk_html and distance_phrase then moving the vector of the chunk_html distance_factor*L2Distance closer to or away from the distance_phrase point along the line between the two points.

Fields

distance_factor: f32

Arbitrary float (positive or negative) specifying the multiplicate factor to apply before summing the phrase vector with the chunk_html embedding vector

phrase: String

Terms to embed in order to create the vector which is weighted summed with the chunk_html embedding vector

Implementations

impl SemanticBoost

pub fn new(distance_factor: f32, phrase: String) -> SemanticBoost

Trait Implementations

impl Clone for SemanticBoost

fn clone(&self) -> SemanticBoost

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SemanticBoost

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

Formats the value using the given formatter.

impl Default for SemanticBoost

fn default() -> SemanticBoost

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for SemanticBoost

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for SemanticBoost

fn eq(&self, other: &SemanticBoost) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for SemanticBoost

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
