Model Driven Development of Social Media Environmental Monitoring Applications

Marco Brambilla, Andrea Mauri, Eric Umuhoza

Introduction

• Social media content analysis being used in very different scenarios– Moreover user generated content has been successfully used

for environmental monitoring

• Issues:– understanding the specific API of each platform;– data integration;

Proposed Solution

• Define a model-driven approach for the development of social media environment monitoring applications– Extension of the Interaction Flow Modeling (IFML) standard

Model Driven Development

• Model-driven development is a development paradigm that uses models as the primary artifact of the development process– Allows abstraction from specific implementation– Improves portability of software to new and changing

technologies– Improves interoperability between different platforms– Enables automatic code generation

IFML

An OMG standard designed for expressing: • Content visualized in the user interfaces• User events and interaction, and • Control behavior of the front-end of SW applications

IFML by Example

Event View Component

Action

Navigation Flow

Requirements• Different type of data sources:

– Ad hoc sensors– User devices

Furthermore people usually use smartphones to share their activities on social media

Requirements

In particular, our aim is to cover two types of applications:• Sensor applications: applications that use smartphone

to gather information regarding the environment and interact with the social networks.

• Analysis applications: applications that gather information from different sources and allow the user to perform complex analysis.

IFML Extensions

• Social Components• IOT Interaction Components• Complex Visualization Components
