Abstract—As numbers of high-quality, large volume
knowledge graphs appear, information extraction work has
been enriched with more semantic knowledge. However, the
entity relation extraction based on the knowledge graph is still
at a very intuitive early stage, and the key issue it faces is the
relation recognition and classification. In order to break the
shackles of ontology and describe the relationship between the
entities with fine-grained types, we propose a two-step
bottom-up abstraction approach for relation conceptualization
based on conceptual taxonomy that is automatically constructed.
Given an entity relation, we figure out a group of Top-K concept
pairs to abstract the relation, according to the typicality,
diversity and coverage features. Our experimental evaluation
shows that our method performing significantly high precision
and quality for detecting fine-grained relationships.
Index Terms—Knowledge graph, entity relationship,
conceptualization, clustering.
