How much is a triple? Estimating the cost of knowledge graph creation - 2018
How much is a triple? Estimating the cost of knowledge graph creation (ISWC-2018)
Feb 21, 2019
一句话总结
手动创建一个三元组(triple)的成本大约在 2 到 6 美元左右,而自动创建知识图谱的成本要降低 15 到 250 倍(即一个三元组 1 美分到 15 美分)。
triple: (subject, relation, object). For example, "(cats, play with, yarn)"
概要
这篇文章很短,大致估计了一下创建每条三元组的成本。
用于比较的知识图谱数据库有两大类型,人工创建和自动创建。人工创建指的是通过人力来制作三元组 。自动创建是通过编写代码,通过代码自动从数据中提取三元组。
人工创建(通过投资或时薪来估算)
cost per assertion = total cost / number of assertions
自动创建(通过每小时的lines of code (LOC)和时薪来估算)
另外不仅要看成本,还要看数据的质量
可以看到人工创建的错误率普遍较低。
