Dataset: Relevance and usability evaluation in a data portal for biodiversity research

Supplementary material for a relevance and usability evaluation in a data portal for biodiversity research.

Data portal: GFBio (https://www.gfbio.org)

Evaluation time: February 2016 (at that time the search index consisted of ~ 2 Mio datasets)

Eight domain experts rated the Top25 search results of 16 provided search questions on a 7-point-Likert scale from 0 (irrelevant) to 6 (highly relevant). Afterwards, we asked the users to provide and rate up to two own queries.

The users also rated 28 statements in a subsequent usability evaluation on a 5-point Likert scale from 'completely disagree' to 'highly agree'. For some statements, only binary ratings were given.

本数据集为面向生物多样性研究的数据门户开展相关性与可用性评估的补充材料。
数据门户：GFBio（https://www.gfbio.org）
评估时间：2016年2月（当时该门户的搜索索引包含约200万个数据集）
八位领域专家针对16个指定搜索问题返回的前25条搜索结果，采用0（完全无关）至6（高度相关）的7点李克特量表（Likert scale）进行评分。随后，要求参与者提交并评分至多两条自定义查询语句。
在后续的可用性评估环节中，参与者还需针对28条陈述，采用从‘完全不同意’至‘高度同意’的5点李克特量表进行评分；部分陈述仅需进行二元评分。
