Semantic Relation Classification: Task Formalisation and Refinement
This work addresses the problem of improving semantic relation classification for domain-specific applications in NLP, though it appears incremental as it refines existing ontology-based approaches.
The paper critiques existing abstract relations for semantic relation classification, particularly their applicability to domain-specific corpora, and proposes a new model based on extending the DOLCE ontology to better capture a wide range of relations.
The identification of semantic relations between terms within texts is a fundamental task in Natural Language Processing which can support applications requiring a lightweight semantic interpretation model. Currently, semantic relation classification concentrates on relations which are evaluated over open-domain data. This work provides a critique on the set of abstract relations used for semantic relation classification with regard to their ability to express relationships between terms which are found in a domain-specific corpora. Based on this analysis, this work proposes an alternative semantic relation model based on reusing and extending the set of abstract relations present in the DOLCE ontology. The resulting set of relations is well grounded, allows to capture a wide range of relations and could thus be used as a foundation for automatic classification of semantic relations.
