WebAnno: A Flexible, Web-based and Visually Supported System for Distributed Annotations
نویسندگان
چکیده
We present WebAnno, a general purpose web-based annotation tool for a wide range of linguistic annotations. WebAnno offers annotation project management, freely configurable tagsets and the management of users in different roles. WebAnno uses modern web technology for visualizing and editing annotations in a web browser. It supports arbitrarily large documents, pluggable import/export filters, the curation of annotations across various users, and an interface to farming out annotations to a crowdsourcing platform. Currently WebAnno allows part-ofspeech, named entity, dependency parsing and co-reference chain annotations. The architecture design allows adding additional modes of visualization and editing, when new kinds of annotations are to be supported.

A Web-based Tool for the Integrated Annotation of Semantic and Syntactic Structures
We introduce the third major release of WebAnno, a generic web-based annotation tool for distributed teams. New features in this release focus on semantic annotation tasks (e.g. semantic role labelling or event annotation) and allow the tight integration of semantic annotations with syntactic annotations. In particular, we introduce the concept of slot features, a novel constraint mechanism tha...
متن کاملAutomatic Annotation Suggestions and Custom Annotation Layers in WebAnno
In this paper, we present a flexible approach to the efficient and exhaustive manual annotation of text documents. For this purpose, we extend WebAnno (Yimam et al., 2013) an open-source web-based annotation tool.1 While it was previously limited to specific annotation layers, our extension allows adding and configuring an arbitrary number of layers through a web-based UI. These layers can be a...
متن کاملSeMFIS: A flexible engineering platform for semantic annotations of conceptual models
In this paper, we present SeMFIS – a flexible engineering platform for semantic annotations of conceptual models. Conceptual models have been used in the past for many purposes in the context of information systems’ engineering. These purposes include for example the elicitation of requirements, the simulation of the behavior of future information systems, the generation of code or the interact...
متن کاملWeb Service Discovery in Large Distributed System Incorporating Semantic Annotations
Web services are the new paradigm for distributed computing. A critical factor to the overall utility of Web services is a scalable, flexible and robust discovery mechanism. Traditional centralized indexing scheme can’t scale well with a large distributed system. In this paper, we first use an ontology-based approach to capture real world knowledge for semantic service annotation. Then we use a...
