participantsboth

Participantsboth is a label used in some conversational data annotation schemes to indicate that both participants in a dyadic interaction are involved in a given segment. The term is not tied to a single standard; rather it functions as a metadata flag to distinguish dyadic engagement from monologic speech or from data where only one participant is active.

Origins and usage of participantsboth occur in discussions of dialogue corpora and user studies where researchers seek to capture simultaneous or collaborative contribution. It is commonly applied during manual annotation or automated tagging alongside attributes such as overlap, interruption, sentiment, or topic. In practice, participantsboth can flag turns or utterance spans that include contributions from both sides, such as overlapping talk or joint actions.

Properties and interpretation of the label vary by project. In some schemes, participantsboth marks a section in which both participants contribute within a single utterance or response; in others it labels a broader window of dialogue where both participants are jointly responsible for content. It often coexists with binary flags for overlap or joint activity.

Relation to other concepts and examples: related terms include single-participant labels or mutual-activity annotations. Example: in annotating a two-person chat, a message from one participant followed by a tightly coupled reply from the other that shows shared responsibility for content may be tagged as participantsboth to reflect the joint contribution. As a niche term, its precise meaning depends on the annotation framework in use.
