AnNER: Annotation and Named Entity Review Tool
AnNER is a web-based tool for annotating text with named entities that, beyond basic annotation functionalities, offers a review mode that allows multiple users to review existing annotations and propose corrections or additions. The tool keeps track of the annotation history and exports a semantic representation of the annotation provenance to increase their trustworthiness, which is critical for large-scale knowledge graph construction and other downstream tasks.
This tool was designed and developed in the Spatial Knowledge and Artificial Intelligence (SKAI) lab at University of Maine. This research was supported in part by the U.S. Department of Agriculture through a National Institute of Food and Agriculture (NIFA) grant, Award #2021-67022-34366
