A knowledge graph is fundamentally defined as a graph structure where nodes represent entities {fact:1, fact:2}, and these entities serve as the core components for semantic relations [1], information retrieval [2], and structural expansion through extraction tasks [3]. Furthermore, the management of these entities is critical to maintaining the efficiency and relevance of the knowledge graph [4].

claimA knowledge graph is a directed graph where nodes indicate entities (real objects or abstract concepts) and edges convey semantic relations between entities.
claimA knowledge graph is a representation of triplets as a graph where edges represent relations and nodes represent entities.
claimKnowledge graph-based information retrieval achieves more accurate retrieval results by analyzing the correlation between queries and documents based on the relations between entities in the knowledge graph, rather than relying solely on similarity matching.

claimRelation extraction (RE) identifies and categorizes relationships between entities in unstructured text to expand knowledge graph structures, while named entity recognition (NER) focuses on recognizing, classifying, and linking entities in text to a knowledge base.

perspectiveRemoving irrelevant entities that do not pertain to the intended domain can be preferable to filling in missing data, as it prevents the knowledge graph from becoming unnecessarily bloated.
