Semantic Annotation is a basic technology for intelligent content and is beneficial in a wide range of contentoriented intelligent applications. In this paper we present our work in ontology-based semantic annotation, which is embedded in a scenario of a knowledge portal application. Starting with seemingly good and bad manual semantic annotation, we describe our experiences made within the KA ...

Annotation, the process of adding extra virtual information to an object, is one of the most common uses for augmented reality. Although annotation is widely used in augmented reality, there is no general agreed-upon definition of what precisely constitutes an annotation in this context. In this paper, we propose a taxonomy of annotation, describing what constitutes an annotation and outlining ...

We present a VerbNet-based annotation scheme for semantic roles which we explore in an annotation study on German language data that combines word sense and semantic role annotation. We reannotate a substantial portion of the SALSA corpus with GermaNet senses and a revised scheme of VerbNet roles. We provide a detailed evaluation of the interaction between sense and role annotation. The resulti...

The shortage of emotion-annotated video datasets suitable for training and validating machine learning models facial expression-based emotion recognition stems primarily from the significant effort cost required manual annotation. In this paper, we present AffecTube as a comprehensive solution that leverages crowdsourcing to annotate videos directly on YouTube platform, resulting in ready-to-us...

The exponential growth of the amount subjective information on Web 2.0. has caused an increasing interest from researchers willing to develop methods extract emotion data these new sources. One most important challenges in textual detection is gathering with labels because subjectivity assigning labels. Basing this rationale, main objective our research contribute resolution challenge. This tac...

Treebank Annotation Issue: Multiple Levels of Annotation • Annotation not on the source text, but more abstract representation • How to maintain annotation consistency and relation between different levels? • How to make available the multiple levels of representation for the user? Arabic Treebank as a case study: • Mapping between two levels of annotation: • Morphological analysis of source te...

Annotation ergonomics – Design guidelines for linguistic annotation tools The paper discusses the chasm between the actual usability qualities of linguistic annotation tools and the requirements of current usability engineering standards and practices. A usability study of three selected annotation tools illustrates typical usability problems. A collection of 28 design guidelines for annotation...

We describe a novel hybrid consistency framework that maintains consistency among Distributed Annotation Records kept at various web-based annotation tools. There are issues in semantics of annotation tools. Each annotation tool stores different metadata, has different rules for tags, and does not provide timing information for the updated records. As a result of these, documents can be updated...
