The Digital Critical Edition of Fragments : Theoretical Problems and Technical Solutions

The process of creating a digital critical edition of fragmentary texts is also a valuable op- portunity to look at the nature of such texts under a new light. This paper contains some reflections about how the nature of fragments can be more appropriately represented in a digital critical edition and what challenges this task poses

Increased Content Accessibility For Wikis And Blogs

This paper aims to introduce a useful approach on the combined use of template based publishing tools (i.e. for blogs and wikis) and content personalization services. The approach considers that the original developers of web content have limited awareness on accessibility issues, and they are facilitated and guided by the editing interface. The publishing mechanism is responsible for storing web content in a flexible representation, where structured content is separated from the formatting information. Intermediate brokering services (i.e aggregators, mediators or simply the portal software) produce multiple versions of the same content in order to increase content accessibility. Finally, end-users are able to set their preferences on how the content will be presented and get a homogeneous representation of the community content. The different versions may comprise multiple languages, audio and text representations etc and be based on a single version of the original content. The structured nature of content produced by template based tools allows intermediate services to intervene and reproduce the original content in various formats and client tools to filter and present information according to user needs and capabilities. The paper presents the focal points of the suggested approach, details on the underlying architecture and presents the required supporting infrastructure

Recent Developments and Future Trends in Volunteered Geographic Information Research: The Case of OpenStreetMap

User-generated content (UGC) platforms on the Internet have experienced a steep increase in data contributions in recent years. The ubiquitous usage of location-enabled devices, such as smartphones, allows contributors to share their geographic information on a number of selected online portals. The collected information is oftentimes referred to as volunteered geographic information (VGI). One of the most utilized, analyzed and cited VGI-platforms, with an increasing popularity over the past few years, is OpenStreetMap (OSM), whose main goal it is to create a freely available geographic database of the world. This paper presents a comprehensive overview of the latest developments in VGI research, focusing on its collaboratively collected geodata and corresponding contributor patterns. Additionally, trends in the realm of OSM research are discussed, highlighting which aspects need to be investigated more closely in the near future

Cognitive Representation Learning of Self-Media Online Article Quality

The automatic quality assessment of self-media online articles is an urgent and new issue, which is of great value to the online recommendation and search. Different from traditional and well-formed articles, self-media online articles are mainly created by users, which have the appearance characteristics of different text levels and multi-modal hybrid editing, along with the potential characteristics of diverse content, different styles, large semantic spans and good interactive experience requirements. To solve these challenges, we establish a joint model CoQAN in combination with the layout organization, writing characteristics and text semantics, designing different representation learning subnetworks, especially for the feature learning process and interactive reading habits on mobile terminals. It is more consistent with the cognitive style of expressing an expert's evaluation of articles. We have also constructed a large scale real-world assessment dataset. Extensive experimental results show that the proposed framework significantly outperforms state-of-the-art methods, and effectively learns and integrates different factors of the online article quality assessment.Comment: Accepted at the Proceedings of the 28th ACM International Conference on Multimedi

Model-Driven Development of Interactive Multimedia Applications

The development of highly interactive multimedia applications is still a challenging and complex task. In addition to the application logic, multimedia applications typically provide a sophisticated user interface with integrated media objects. As a consequence, the development process involves different experts for software design, user interface design, and media design. There is still a lack of concepts for a systematic development which integrates these aspects. This thesis provides a model-driven development approach addressing this problem. Therefore it introduces the Multimedia Modeling Language (MML), a visual modeling language supporting a design phase in multimedia application development. The language is oriented on well-established software engineering concepts, like UML 2, and integrates concepts from the areas of multimedia development and model-based user interface development. MML allows the generation of code skeletons from the models. Thereby, the core idea is to generate code skeletons which can be directly processed in multimedia authoring tools. In this way, the strengths of both are combined: Authoring tools are used to perform the creative development tasks while models are used to design the overall application structure and to enable a well-coordinated development process. This is demonstrated using the professional authoring tool Adobe Flash. MML is supported by modeling and code generation tools which have been used to validate the approach over several years in various student projects and teaching courses. Additional prototypes have been developed to demonstrate, e.g., the ability to generate code for different target platforms. Finally, it is discussed how models can contribute in general to a better integration of well-structured software development and creative visual design

Automatische Reputationsmessung in der Wikipedia

Die Wikipedia wird im Rahmen ihres offenen Zugangs von Autorenerstellt, die überwiegend anonym oder unter Pseudonym tätigund damit weitgehend unbekannt sind. Daraus resultiert eine Unsicherheitbezüglich der Güte der einzelnen Beiträge. Einen Lösungsansatzbieten automatische Reputationssysteme, die sich inden vergangenen Jahren als eigenständiges Forschungsgebietetabliert haben. Durch diese Reputationssysteme wird die Reputationder Autoren anhand ihrer bisherigen Bearbeitungen automatischberechnet. In der gegenwärtigen Forschung werden die zurReputationsmessung vorgeschlagenen Metriken jedoch nur isoliertbetrachtet und oft unzureichend bewertet, sodass sich derenAussagekraft nur schwer abschätzen lässt. Im vorliegenden Beitragwerden insgesamt zehn Metriken vergleichend bewertet unddurch Kombination anhand einer Diskriminanzanalyse zu einereffizienten Reputationsfunktion zusammengeführt. Die Metrikenwurden der bestehenden Literatur entnommen und um eigeneVorschläge ergänzt. Die Analyse zeigt, dass die neu vorgeschlageneMetrik der Effizienz der Bearbeitungen besonders aussagekräftigist

Monitoring oriented agile based web applications development methodology for small software firms in Jordan

Small software firms (SSF) is vital to the software industry in many countries as they provide substantial growth to their economy. In Jordan, most software companies that are involved with developing Web applications are small firms. However, the extent of applying best Web applications development and management practices in these firms is limited. Besides, the existing software development methods are still lack of monitoring the quality of process and product. As a result, the Web application being developed exceeds deadlines and budget, and not meeting user requirements. Therefore, this research aims to construct a new methodology referred as Monitoring Oriented Agile Based Web Applications Development (MOGWD) Methodology for SSF. This study introduced an Extended Agile Method by extending the Scrum method with Extreme Programming (XP) elements. The Extended Agile Method was improved by combining common steps of Web design method and incorporating the Goal Oriented Monitoring Method (GOMM). The GOMM has defined twenty goals. Each goal has one or more questions. The questions are answered through the defined metrics. There are 101 qualitative metrics for monitoring the process quality, and 37 quantitative metrics for monitoring the process and product quality. Moreover, the proposed MOGWD methodology defines four phases: Plan, Do, Check and Act. The MOGWD methodology was evaluated using expert review and case study. The evaluation results show that the MOGWD methodology has gained SSF practitioners’ satisfaction and found to be practical for the real environment. This study contributes to the field of Agile based development and Web applications measurement. It also provides SSF practitioners a development methodology that monitors the quality of the process and product for Web development
