本体论框架

Ontology Framework

概述本文总结当前主流的语义网络（知识图谱）领域的本体描述框架，包括理论，语言和系统。其中本体论介绍相关理论发展，以及大家对其形而上学的争论；本体工程介绍若干基础和领域的本体概念集；本体语言介绍典型的知识表示语言及其发展过程。最后展望在大语言模型变革下的本体论技术发展趋势。简史符号知识系统的发展，从最初的通用问题解决器GPS 到最近的语义网络和知识图谱，经历了多次的基础理论迭代和系...

What Javascript Surprises Me

背景我比较喜欢研究计算机语言理论。所有的计算机语言来自于历史上诸多计算机学者和工程人员的努力。每种语言都有生而为之的特征。每年都有诸多计算机语言诞生，而追寻每种语言背后的故事以及了解它们的与众不同的特点，很有意思。这是What X surprises me系列文章之一，记录某种语言的设计特点在我的认知中带来某种惊讶或惊喜。有点钟书先生《管锥编》异曲同工之意。这篇有关Javasci...

我站在比特之巅，凝望着知识之渊

Staring Into The Abyss of Knowledge

题记：徘徊在数字的世界里，我有时感觉像个富有的国王，有时又像是暗夜中前行的乞者。我时而站在比特之巅，笑傲群山；时而被逼仄无路，如临深渊… 经过三十多年数字化技术的高速发展，人类积累了巨量的比特数据。如果这句话听起来那么平庸，下面的统计数据会让你有更直观的感受： 2020年人均每秒产生1.7MB数据，每天人类产生2.5EB (1EB=10^9GB) 截至2020年底，整个数字世界...

元数据的可计算化反 III

The Computability of Metadata (Part 3)

一点有关链接数据到图模型映射的思考: Mapping from Linked-Data Model to Labeld Property Graph 仅仅是一些思考片段，省略了很多背景知识，比如关联数据、元数据、知识表示、图计算等等。不求看官解，自娱耳。有兴趣的可以探讨。 OWL/RDFS/RDF是目前为止，普遍被业界接受的一种描述性链接数据范式。其优势在于描述知识的方法灵活，科研和工业...
