Effective and Efficient Retrieval of Structured Entities

Summary: Introduces a hierarchy-smooth function to aggregate term scores across nested structured entities, mitigating parent–child containment in retrieval. Learns aggregation coefficients from entity families; works with BOW or word embeddings; enables efficient, accurate retrieval across heterogeneous structures on real data.
