brat: a Web-based Tool for NLP-Assisted Text Annotation
نویسندگان
چکیده
We introduce the brat rapid annotation tool (BRAT), an intuitive web-based tool for text annotation supported by Natural Language Processing (NLP) technology. BRAT has been developed for rich structured annotation for a variety of NLP tasks and aims to support manual curation efforts and increase annotator productivity using NLP techniques. We discuss several case studies of real-world annotation projects using pre-release versions of BRAT and present an evaluation of annotation assisted by semantic class disambiguation on a multicategory entity mention annotation task, showing a 15% decrease in total annotation time. BRAT is available under an opensource license from: http://brat.nlplab.org

GraPAT: a Tool for Graph Annotations
We introduce GraPAT, a web-based annotation tool for building graph structures over text. Graphs have been demonstrated to be relevant in a variety of quite diverse annotation efforts and in different NLP applications, and they serve to model annotators’ intuitions quite closely. In particular, in this paper we discuss the implementation of graph annotations for sentiment analysis, argumentatio...
متن کاملDjangology: A Light-weight Web-based Tool for Distributed Collaborative Text Annotation
Manual text annotation is a resource-consuming endeavor necessary for NLP systems when they target new tasks or domains for which there are no existing annotated corpora. Distributing the annotation work across multiple contributors is a natural solution to reduce and manage the effort required. Although there are a few publicly available tools which support distributed collaborative text annot...

متن کاملNLP Web Services for Slovene and English: Morphosyntactic Tagging, Lemmatisation and Definition Extraction
This paper presents a web service for automatic linguistic annotation of Slovene and English texts. The web service enables text up-loading in a number of different input formats, and then converts, tokenises, tags and lemmatises the text, and returns the annotated text. The paper presents the ToTrTaLe annotation tool, and the implementation of the annotation workflow in two workflow constructi...
متن کاملAnnotation Process Management Revisited
Proper annotation process management is crucial to the construction of corpora, which are indispensable to the data-driven techniques that have come to the forefront in NLP during the last two decades. This paper first raises a list of 10 needs that any general purpose annotation system should address, such as user & role management, delegation & monitoring of work, diffing annotators’ work, ve...
