Struct WikipediaKnowledgeStore 

pub struct WikipediaKnowledgeStore {
    pub entity_types: HashMap<String, WikidataNERType>,
    pub outlinks: HashMap<String, HashSet<String>>,
    pub categories: HashMap<String, Vec<String>>,
    pub dictionary: Option<Arc<WikidataDictionary>>,
}

Store of Wikipedia/Wikidata knowledge for joint inference.

Provides semantic information about entities:

• Type mappings (Q5 → Person, Q43229 → Organization)
• Outgoing links (for relatedness computation)
• Categories

Fields

entity_types: HashMap<String, WikidataNERType>

Entity types by KB ID

outlinks: HashMap<String, HashSet<String>>

Outgoing links by KB ID

categories: HashMap<String, Vec<String>>

Categories by KB ID

dictionary: Option<Arc<WikidataDictionary>>

Wikidata dictionary for type lookups

Implementations

impl WikipediaKnowledgeStore

pub fn new() -> Self

Create a new empty store.

pub fn from_dictionary(dict: WikidataDictionary) -> Self

Create from a Wikidata dictionary.

pub fn get_type(&self, kb_id: &str) -> Option<WikidataNERType>

Get the entity type for a KB ID.

pub fn add_type(&mut self, kb_id: &str, ner_type: WikidataNERType)

Add a type mapping.

pub fn add_outlinks( &mut self, kb_id: &str, links: impl IntoIterator<Item = String>, )

Add outgoing links for an entity.

pub fn shared_outlinks(&self, kb_id_a: &str, kb_id_b: &str) -> usize

Check if two entities share outlinks.

pub fn has_link(&self, from: &str, to: &str) -> bool

Check if one entity links to another.

pub fn mutual_link(&self, kb_id_a: &str, kb_id_b: &str) -> bool

Check if entities mutually link to each other.

pub fn relatedness(&self, kb_id_a: &str, kb_id_b: &str) -> f64

Compute relatedness score between two entities.

Based on Wikipedia link structure (Milne & Witten 2008 style).
