"Temporal information in natural language texts is an increasingly important component to the understanding of those texts. ISO 24617-1:2012, SemAF-Time, specifies a formalized XML-based markup language called ISO-TimeML, with a systematic way to extract and represent temporal information, as well as to facilitate the exchange of temporal information, both between operational language processing systems and between different temporal representation schemes. The use of guidelines for temporal annotation has been fully attested with examples from the TimeBank corpus, a collection of 183 documents that have been annotated by TimeML before the current version of ISO-TimeML was formulated." (Abstract, ISO 24617-1:2012)

"ISO 24617-2:2012 provides a set of empirically and theoretically well-motivated concepts for dialogue annotation, a formal language for expressing dialogue annotations -- the dialogue act markup language (DiAML) -- and a method for segmenting a dialogue into semantic units. This allows the manual or automatic annotation of dialogue segments with information about the communicative actions which the participants perform by their contributions to the dialogue. It supports multidimensional annotation, in which units in dialogue are viewed as having multiple communicative functions. The DiAML language has an XML-based representation format and a formal semantics which makes it possible to apply inference to DiAML representations.

ISO 24617-2:2012 specifies data categories for reference sets of communicative functions and dimensions of dialogue analysis and provides principles and guidelines for extending these sets or selecting coherent subsets of them. Additionally, it provides guidelines for annotators and annotated examples. It is applicable to spoken, written and multimodal dialogues involving two or more participants."

"The aim of ISO 24617-4:2014 is to propose a consensual annotation scheme for semantic roles; that is to say, a scheme that indicates the role that a participant plays in an event or state, as described mostly by a verb, and typically providing answers to questions such as "?who' did ?what' to ?whom'", and ?when', ?where', ?why', and ?how'. This includes not only the semantic relations between a verb and its arguments but also those relations that are relevant for other predicative elements such as nominalizations, nouns, adjectives, and predicate modifiers; the predicating role of adverbs and the use of coercion fall outside the scope of ISO 24617-4:2014."

"A discourse is a process of communication. ISO/TS 24617-5:2014 addresses how a discourse is structured in terms of its realization/presentation and content, and shows how its dual structure can be represented in a graph. The current specification focuses on the annotation of discourse structures in text only, but it can be extended to discourses in other modalities." Abstract, ISO/TS 24617-5:2014
