Challenges


Introduction

Semantic Content Authoring (SCA) is cumbersome!

There is a lack of approaches, technologies and tools to facilitate collaboration.

There is a lack of incentives and instant gratification for users to adopt SCA.

There is a lack of standardization of UI technologies in the domain of SCA.

Research Questions


Introduction

How can we enable user-friendly manual and semi-automatic creation of rich semantic content?

What are existing approaches for user-friendly semantic content authoring? How to classify existing approaches for semantic content authoring? What types of user interfaces are used by each approach? What are the features supported by the proposed user interfaces? What types of users are targeted in each approach? How is the user interface evaluated?

How can we bind user interface elements to semantic representation data models? How can we integrate semantic content authoring features into the current authoring tools on the Social Web?

How can we exploit semantically-enriched content for content analysis? Can we utilize semantic content benefits to incentivize users contributing to the process of manual semantic content authoring?

How can we apply crowdsourcing & collaborative content authoring techniques to the process of semantic content authoring?

How can we apply semantic content authoring to a domain-specific use case for achieving content interoperability?
