Structured Templates for Authoring Semantically Rich Documents

International audienceStructured documents associate explicit semantics with content, but authoring rigorously structured documents is a very difficult task. We present a new approach to this issue that adds schema-level information to the popular web formats. This makes editing highly structured documents easier, while ensuring that documents are valid. It is also an easy way to publish semantically rich documents on the web. The impact of this approach on authoring tools is discussed and its implementation in the Amaya editor is briefly presented

Authoring XML all the Time, Everywhere and by Everyone

International audienceThis article presents a framework for editing, publishing and sharing XML content directly from within the browser. It comes in two parts: XTiger XML and AXEL. XTiger XML is a document template specification language for creating document models. AXEL is a client-side Javascript library that turns the document template into a document editing application running in the browser. This framework is targeted at non XML speaking end users, since it preserves end users from XML syntax during editing. Its current implementation proposes a pseudo-WYSIWYG user interface where the document template provides a document-oriented editing metaphor, or a more form-oriented metaphor, depending on the template

A Semantics-based User Interface Model for Content Annotation, Authoring and Exploration

The Semantic Web and Linked Data movements with the aim of creating, publishing and interconnecting machine readable information have gained traction in the last years. However, the majority of information still is contained in and exchanged using unstructured documents, such as Web pages, text documents, images and videos. This can also not be expected to change, since text, images and videos are the natural way in which humans interact with information. Semantic structuring of content on the other hand provides a wide range of advantages compared to unstructured information. Semantically-enriched documents facilitate information search and retrieval, presentation, integration, reusability, interoperability and personalization. Looking at the life-cycle of semantic content on the Web of Data, we see quite some progress on the backend side in storing structured content or for linking data and schemata. Nevertheless, the currently least developed aspect of the semantic content life-cycle is from our point of view the user-friendly manual and semi-automatic creation of rich semantic content. In this thesis, we propose a semantics-based user interface model, which aims to reduce the complexity of underlying technologies for semantic enrichment of content by Web users. By surveying existing tools and approaches for semantic content authoring, we extracted a set of guidelines for designing efficient and effective semantic authoring user interfaces. We applied these guidelines to devise a semantics-based user interface model called WYSIWYM (What You See Is What You Mean) which enables integrated authoring, visualization and exploration of unstructured and (semi-)structured content. To assess the applicability of our proposed WYSIWYM model, we incorporated the model into four real-world use cases comprising two general and two domain-specific applications. These use cases address four aspects of the WYSIWYM implementation: 1) Its integration into existing user interfaces, 2) Utilizing it for lightweight text analytics to incentivize users, 3) Dealing with crowdsourcing of semi-structured e-learning content, 4) Incorporating it for authoring of semantic medical prescriptions
