- AKA: TRET.
- It can be supported by: Semantic Parsing from Text, Relation Mention Recognition, Relation Mention Classification, ...
- It can be solved by a Semantic Relation Mention Extraction System (that implements a semantic relation mention extraction algorithm).
- It can range from being a Manual Semantic Relation Extraction Task to being an Automated Semantic Relation Extraction Task.
- It can range from being a Heuristic Relation Mention Extraction Task to being a Data-Driven Relation Mention Extraction Task (such as a supervised relation mention extraction).
- It can range from being a Single-Sentence Textual Relation Extraction Task to being a Multi-Sentence Textual Relation Extraction Task.
- It can range from being a Domain-Specific Textual Relation Extraction Task to being a Common Knowledge-based Textual Relation Extraction Task.

- Relation extraction is the task of discovering semantic connections between entities. In text, this usually amounts to examining pairs of entities in a document and determining (from local language cues) whether a relation exists between them. Common approaches to this problem include pattern matching (Brin, 1998; Agichtein and Gravano, 2000), kernel methods (Zelenko et al., 2003; Culotta and Sorensen, 2004; Bunescu and Mooney, 2006), logistic regression (Kambhatla, 2004), and augmented parsing (Miller et al., 2000).
