Corpusdialogs

Corpusdialogs is a term used in corpus linguistics and natural language processing to refer to the practice of creating and analyzing dialog-centered corpora—large collections of transcribed conversations and associated metadata. Such corpora capture conversational interactions across genres, languages, and modalities, and they are used for linguistic analysis as well as for building and evaluating dialogue systems.

A typical corpus dialogs dataset includes transcripts of spoken or written dialogues, speaker labels, turn boundaries, timestamps, and annotation layers such as dialogue acts, topic segments, sentiment, and coreference. Data may come from telephone conversations, meetings, customer service chats, or scripted media, and is often accompanied by audio, alignment, and metadata about participants and setting. Ethical and legal considerations, including privacy and licensing, guide collection and release.

Annotation schemes vary; common formats encode who spoke what, when, and what the speaker intends. Dialogue-act taxonomies, intent labels, and discourse markers help researchers examine interaction patterns, repair sequences, and backchannel behavior. Interoperability is aided by standard schemas and data formats, though diversity remains a challenge for cross-corpus research.

Applications include training and evaluating conversational agents, building dialogue managers, and supporting linguistic research in turn-taking, reference resolution, and pragmatics. Corpus dialogs also enable empirical studies of speech recognition and sentiment in natural conversations and facilitate cross-linguistic comparisons.

Challenges include ensuring representative coverage, addressing privacy, navigating copyright, and achieving annotation consistency. Reproducibility and comparability across corpora are ongoing concerns in the field. Notable related resources include established dialogue corpora such as the Switchboard and AMI corpora, which serve as benchmarks for methods developed from corpus dialogs.
