referentssuch

Referentssuch is a term used to describe the process of identifying the entity or concept to which a linguistic expression refers. It covers tasks in which a speaker, listener, or computational system must determine the intended referent of pronouns, noun phrases, deictic terms, or other referring expressions based on linguistic cues and contextual information.

The concept spans multiple disciplines including linguistics, cognitive science, artificial intelligence, and information retrieval. In linguistics it overlaps with coreference and anaphora resolution; in AI it aligns with entity linking and referent resolution in dialogue systems. Methods applied to referentssuch range from rule-based heuristics grounded in syntax and discourse structure to statistical and neural models that exploit large annotated corpora and contextual embeddings.

Common challenges include lexical ambiguity, sparse contextual cues, shifting discourse focus, and reliance on world knowledge or intent inference. Practical applications include machine translation, conversational agents, automated summarization, and knowledge-base population, where accurate identification of referents is essential for coherence and correctness.

The term is often used descriptively rather than as a formal technical standard; related notions include coreference resolution, anaphora resolution, and entity disambiguation. Progress in the field has been driven by advances in contextual language models, but persistent difficulties remain when referent identification requires commonsense reasoning or multimodal context.
