Codes, according to Knight (2011: 197-198) are ‘physical forms of discourse-level annotations which mark specific semantic, pragmatic, and/or functional characteristics of discourse in a corpus. These are often used as a point of entry for analysing specific features of corpora.’ Though many coding schemes have been implemented and some of these are adaptable to other projects, there remains an absence of a standard coding scheme that can be universally adopted. As coding for multiple modes of behaviours (and across multiple speakers) can be time-consuming, it is recommended that a coding scheme be set from the outset that is tailored to the needs of a given research project. Variation in schemes is dependent on a number of factors, including:
- The specific modes and non-verbal behaviours that are intended to be analysed.
- The system of annotation used and the tools used to facilitate this from annotations embedded into transcripts to sophisticated use of multi-modal tools that represent levels of co-occurrence on tiers.
- The level of detail that the researcher intends to analyse. This will place a scheme on a spectrum of broad to fine-grained (Yang et al. 2022). For example, some researchers may be interested in phases of behaviour, while others may be interested only in instances.
The degree to which automaticity is integrated into the system of annotation using tools such as the SPeeding Up the Detection of Non-iconic and Iconic Gestures (SPUDNIG) tool which aims to speed up the annotation of hand gestures in ELAN. This list is not intended to be definitive or exhaustive but rather to be a document of examples of a variety of approaches to coding which others may use a starting point or reference for how to undertake the creation or adaption of a bespoke coding scheme. This is a list of notable projects that have either created multi-modal datasets and/or bespoke and replicable coding schemes.
Project/corpus: Video-mediated English as a Lingua Franca Conversations (ViMELF)

Link: https://varieng.helsinki.fi/CoRD/corpora/ViMELF/
System: Annotations integrated into textual transcription
Research focus: The analysis of multi-modal features of communication using English as a lingua franca in virtual meetings.
Description: Consists of 55 Non-Verbal Elements (NVEs). Nine are associated with facial expressions, four with the head, including gaze features, three with physical stance and two with the speakers’ background. 39 features are associated with hand or body movement; these include movement, but also actions such as standing up, walking, or camera movements that force a shift of perspective.
Project/corpus: MUMIN – A Nordic Network for MUltiModal Interfaces

System: Annotations on tiers using Anvil multi-modal corpus tool
Research focus: Originally created to experiment with annotation of multimodal communication in short clips from movies and in video clips of interviews taken from Swedish, Finnish and Danish television broadcasting but also intends to be a general instrument for the study of gestures and facial displays in interpersonal communication, in particular the role played by multimodal expressions for feedback, turn management and sequencing.
Description: This coding scheme works on two levels: form and function.
Form is tagged depending on the feature. Hand forms are tagged for ‘handedness’ i.e. both or single and trajectory i.e. up, down, sideways, complex, other.
The functions relate to feedback, turn management and sequencing. Each of these have sub-categories and short tags. For example, ‘sequencing’ is categorised as opening, continuing and closing tagged as S-open, S-continue and S-close respectively. Semiotic types are categorised as Indexical Deictic, Indexical Nondeictic, Iconic and Symbolic.

The pragmatic categories are: Referential, Operational, Modal, Performative, Discourse Marking, and Interactional.

Link: CLARIN blog post
Research focus: To investigate the nature and temporal alignment of verbal and nonverbal features of spontaneous speech as well as to compare the characteristics of formal and informal communication in Hungarian to improve human-machine communication applications (like chatbots) by empowering them with a comprehensive set of knowledge about human-human communicative behaviour.
System: Tiers in ELAN
Description: Annotations carried out based on either one mode (audio only or video only) or two modes (audio and video). The corpus also includes syntactic, prosodic and pragmatic annotation. The syntactic annotation was restricted to the identification and classification of clauses and sentences.
The pragmatic annotation was carried out on two separate levels, multimodal (based on both audio and video) and unimodal (based on video only). Multimodal pragmatic annotation codes communicative functions and speaker intentions.
