Ontology for the Annotation of Push-Notifications (APN) Version 0.1. Edited by Beatriz Esteves, Kieran Fraser, and Shridhar Kulkarni. 16 February 2022. https://w3id.org/apn/.

Abstract

The ontology for the Annotation of Push-Notifications (APN) aims to provide a tool that can be used to model different aspects of push-notifications, i.e., communication tools used by apps and services to disseminate information, engage with their users and encourage users to take particular actions. The scope of this ontology is limited to the definition of a set of parameters that can be used to classify push-notification data, in particular its text content, with the end goal of creating a service which pushes more empathetic content to push-notification subscribers.

2. Introduction

2.1 Ontology Requirement Specification Document

Ontology for the Annotation of Push-Notifications
1. Purpose
The purpose of this ontology is to support the annotation and extraction of insights from push-notification data.
2. Scope
The scope of this ontology is limited to the definition of a set of parameters that can be used to classify push-notification data, in particular its text content, with the end goal of creating a service which pushes more empathethic content to push-notification subscribers. Specifically, the notification content will be used to categorize the notification in terms of: (i) its specific call-to-action, (ii) and respective marketing campaign type, (iii) its target audience, (iv) its time sensitiveness and (v) the presence of information that can be used to infer personal data from the subscribers.
3. Implementation Language
RDF
4. Intended End-Users
Organizations with Web or application services which include push-notifications in their communication flow with customers.
5. Intended Uses
Use 1. Creation of multi-label classification models to automatically annotate push-notifications.
Use 2. Generation of push-notification content based on annotations' model.
6. Ontology Requirements
a. Non-Functional Requirements
NFR 1. The ontology shall be published online with standard documentation.
b. Functional Requirements: Groups of Competency Questions
CQG1. Related to push-notification services CQG2. Related to push-notification categorization
CQ1. What is the content of the push-notification?
CQ2. Which service / application pushed the notification?
CQ3. What is the application type in relation to its content? 		CQ4. What is the call-to-action of the notification?
CQ5. Does the notification belong to a specific campaign type?
CQ6. How urgent is the notification?
CQ7. Does the notification have a clear target audience?
CQ8. Does the notification contain features which indicate personalization?
