Standards Development

Scope

This document provides an overview of city knowledge trustworthiness and its evaluation in the context of smart cities, including the following: concepts relevant to city knowledge trustworthiness and its evaluation; characteristics of trustworthiness of city knowledge; and methodology for the evaluation of city knowledge trustworthiness. This document also provides some use cases for city knowledge use in smart cities and some cases for city knowledge trustworthiness evaluation.

Purpose

The comprehensive digital transformation of a city has produced a huge amount of data about the city, which describes a lot of knowledge about the city that we call the city knowledge. This city knowledge can tell us about the history, present and future of the city, how the city has developed, and what the current operating condition is like. Using this knowledge, we can manage the city affairs, solve the problems of urbanization, make more precise and smart decisions, and plan the development and future of the city.

City knowledge refers to abstracted information about objects, events, concepts, or rules, including their relationships and properties within a city. This organized knowledge supports city planning, operation, and stakeholders' activities. To make a city smarter, it is crucial to leverage this knowledge as the foundation for developing more intelligent city operation modes and city services. Furthermore, city services in different areas will also utilize knowledge generated in other service areas.

A knowledge user could be a person, organization, system, product, or service who relies on the acquired knowledge of a city to some extent. For instance, when city planners and planning management departments create and approve city planning schemes, the provided knowledge about the city must be accurate to reflect its current state. This accuracy is crucial to avoid making incorrect decisions and implementing unfeasible policies.

In terms of city knowledge management, ISO/IEC 30145-2:2020 provides a framework for knowledge management, in which knowledge trustworthiness evaluation is an element of the smart city knowledge management platform. City knowledge is crucial in smart cities, but in different scenarios different levels or degrees of trustworthiness are required. There isn't a unified standard for determining trustworthiness, as it depends on various factors such as the environment, user goals, and the organization providing the knowledge. A common evaluation methodology and framework for evaluating the trustworthiness of city knowledge would help city stakeholders make better decisions for city planning and management, operation and service delivery.

This document is the first part of a series of standards for evaluating the trustworthiness of city knowledge. Its purpose is to establish a common understanding of city knowledge, trustworthiness, and the methodology for evaluating knowledge trustworthiness in the context of smart cities. This involves analyzing use cases and practical evaluation methodologies for city knowledge trustworthiness.
