摘要

用帮助算法信息理论阐述和解释了人类与数字宇宙之间越来越大的语义差距问题。我们使用数字宇宙不仅是最大的信息集合,而且因为它是任何时候最接近通用参考机的。我们在一个简单的模型中演示了如何在数据库内容已知的情况下估计查询和答案的信息量。此外,我们还可以估计数据库增长对查询和答案长度的影响。通过对大数据炒作的一些评论,解决了“什么”、“在哪里”和“何时”的问题。

The digital universe - an information theoretical analyses
The problem of the growing semantic gap between mankind and the Digital Universe is formulated and explained by the help algorithmic information theory. We use The Digital Universe as not only the largest collection of information but as it is the anytime best approximation of the Universal Reference Machine. We demonstrate in a simple model how the information quantity of queries and answers can be estimated under the condition that the content of the database is known. Also, we can estimate the effect of database growth on the length of queries and answers. The problem of "What", Where" and "When" is addressed with some remarks on Big Data hype.
