topicindicating

Topicindicating is a term used in linguistics and information science to describe signals that mark the topic of a clause or discourse segment. In information-structure theory, the topic is the element that the rest of the sentence is about, as distinct from the focus or comment. Topicindicating signals thus guide listeners toward the intended anchor of discourse and contribute to coherence and referential continuity.

The set of topicindicating mechanisms is broad. It includes pronouns and determiners that re-mention a topic, demonstratives, and language-specific topic markers, as well as prosodic cues and discourse markers. In practice, a speaker may use phrases like “as for X” or “speaking of X” to shift or signal a topic in English. Some languages employ explicit topic markers, such as the Japanese particle wa (は) or the Korean topic markers nu/neun, while others rely more on word order and intonation to signal topic. Across languages, topicindicating devices work together with other information-structuring tools to establish what is already known, what is new, and what the main comment is about.

In computational linguistics and natural language processing, topicindicating cues are used to improve discourse parsing, summarization, and dialogue management. Algorithms may target discourse markers, pronoun resolution, or topical particles to segment text into coherent topics and to maintain topical continuity across sentences or turns.
