Real bird dataset with imprecise and uncertain values

本数据集名为‘Real bird dataset with imprecise and uncertain values’，由法国的研究机构通过众包方式创建。数据集包含5000条数据，主要来源于众包活动中人类贡献者对鸟类照片的标注。数据集的创建过程中，贡献者被要求在识别鸟类时提供其答案的不确定性程度。该数据集主要用于信念函数理论的研究，旨在解决数据不确定性和非精确性问题，特别是在机器学习和数据融合领域。

This dataset is named 'Real bird dataset with imprecise and uncertain values', which was created by a French research institution via crowdsourcing. It contains 5,000 data entries, primarily sourced from the bird photo annotations provided by human contributors during crowdsourcing activities. During the dataset's creation, contributors were required to provide the uncertainty degree of their answers when identifying bird species. This dataset is mainly used for research on belief function theory, aiming to address issues of data uncertainty and imprecision, especially in the fields of machine learning and data fusion.
