What is ISO 24617‑7 about?
ISO 24617‑7 is part seven of the multi-series standard that provides a framework for encoding a broad range of spatial information and spatiotemporal information relating to motion as expressed in natural language texts.
ISO 24617‑7 includes references to locations, general spatial entities, spatial relations (involving topological, orientational, and metric values), dimensional information, motion events, paths, and event-paths triggered by motions.]
Who is ISO 24617‑7 for?
ISO 24617‑7 on semantic annotation framework- spatial information is useful for:
- Computational linguists
- Artificial intelligence researchers and developers
- Language developers
- Writers
- Books publishers
- Bloggers
Why should you use ISO 24617‑7?
There is a growing demand for such annotated data, particularly in the context of the
semantic web. Moreover, textual data routinely make reference to objects moving through space over time. Integrating such information derived from textual sources into a Geo sensor data system can enhance the overall spatiotemporal representation in changing and evolving situations, such as when tracking objects through space with limited image data.
ISO 24617‑7 provides normative specifications for spatial information and information content in motion and various other types of events in language.
ISO 24617‑7 helps you in-
- Creating a visualization of objects from a verbal description of a scene
- Identifying the spatial relations associated with a sequence of processes and events from a news article
- Determining an object location or tracking a moving object from a verbal description
- Translating viewer-centric verbal descriptions into other relative descriptions or absolute coordinate descriptions
- Constructing a route given a route description
- Constructing a spatial model of an interior or exterior space given a verbal description
- Integrating spatial descriptions with information from other media
ISO 24617‑7 captures complex constructions in text in order to provide an inventory of how spatial information is presented in natural language.
ISO 24617‑7 aims to formulate the requirements for static and dynamic spatial annotation standards.
What’s changed since the last update?
BS ISO 24617‑7:2020 is the second edition that replaces the first edition (ISO 24617-7:2014), which has been technically revised. It aims at satisfying the requirements and recommendations laid down in ISO 24617-6.
The main changes compared to the previous edition are as follows.
- Event-paths (
), which are triggered by motions, are restored as objects of a basic entity type in concrete syntaxes as well as in the abstract syntax. - It focuses on spatial relations only, thus tagging them as
. There are no or as such. Path adjuncts are treated as pathDefining spatial relations, tagged as . - The movement link (
) is very much modified to conform to the general link structure, as specified in ISO 24617-6. This general link structure minimally consists of a relation type and two required arguments, represented by two attribute names, @figure and @ground, which are single entity structures and sets of entity structures, respectively. The addition of optional (implied) attributes such as @trigger (relator) for or @bounds for is allowed. - The measure link (
) is generalized to accommodate not only spatial measures such as distances but temporal or spatio-temporal measures that include durations, time amounts or speeds. The two optional attributes @endPoint1 and @endPoint2 are also generalized to apply to areas (oceans) or borderlines (rivers, mountain ranges) with a new attribute @bounds, replacing those two attributes. - As a result, most of the specifications of the attribute-value assignments to each of the entity types and those of the link types, represented in extended BNF, or XML DTD (data type declarations), are revised. The UML figures representing them are also revised or deleted.
- The list of tags associated with entity structures and link structures is presented in a tabular form to make these structures more comparable in a visual way. This list has been given in Clause 4, Table 1.
- To make the document more compact and less burdensome for the readers, Annex A, Guidelines, has been deleted.
