Advanced Features of Collaborative Semantic Annotators — The 4A System
Pavel Smrž, Jaroslav Dytrych · The Florida AI Research Society · 2015
This paper deals with collaborative knowledge engineering, particularly focusing on collective editing and semantic annotation of hypertext. It discusses state-of-the-art functions of the 4A (Annotations Anywhere, Annotations Anytime) system that has been recently extended to be applicable in a broad range of annotation contexts. We introduce advanced features and recent improvements that make the tool unique in many aspects. A special attention is paid to the social way of semantic tagging ‐ complex annotations can be created by a single click and immediately shared with other interested users or reused by external systems. We also compare the 4A system to similar software solutions and show their similarities and differences.
