Part3. Graph Representation Learning

Problem: structural feature engineering over the graph is expensive.
=> Graph Representation Learning aimed to learn latent(潜在的) feature matrix

Representation learning for graph mining?
The goal is to map each node into a latent low-dimensional space such that network structure information is encoded into distributional node representations.

Part1. Introduction and Overview

Part2. Graph Properties and Applications

1. Graph Basics

Degree

Degree in Microsoft Academic Graph(MAG):

• Author collaboration graph(undirected graph)

  Degree represents the number of collaborators each author has.

• Paper citation graph(directed graph)

  In-degree represents the number of citations each paper collects.
  Out-degree represents the number of references each paper covers.

• Institution collaboration graph
• Institution citation graph
• Field-of-study citation graph
• Venue citation graph

NLP(Neuro-linguistic programming) + Information Extraction

Breaking it down

1) Tokenization & Sentence Splitting
2) Tagging the Parts of Speech
3) Detecting Named Entities
4) Dependency Parsing

Part 1 Knowledge Graph Primer

1. What is a Knowledge Graph?

Knowledge Graph = Entities + Relationships + Attributes

Popular Knowledge Graphs(General): Google Knowledge Graph, Microsofy Satori Knowledge Graph
Domain Specific Knowledge Graphs: Microsoft Academic Graph, Linkedin Economic Graph, Common Sense Knowledge Graph

1. Git原理

workspace: 工作区
Index/Stage: 暂存区
Repository：仓库区（或本地仓库）
Remote：远程仓库

声明和使用变量

字符串文本以 $ 字符开头，后接左双引号字符。 $ 符号和引号字符之间不能有空格。 则可以在大括号之间的字符串内包括变量。

如： Console.WriteLine($”Hello {aFriend}”);
Console.WriteLine($”The name {firstFriend} has {firstFriend.Length} letters.”);
