One-line Tree in Python

Using Python's built-in defaultdict we can easily define a tree data structure:

def tree(): return defaultdict(tree)

That's it!

System Design Cheatsheet

Picking the right architecture = Picking the right battles + Managing trade-offs

Basic Steps

1. Clarify and agree on the scope of the system

• User cases (description of sequences of events that, taken together, lead to a system doing something useful)
  • Who is going to use it?
  • How are they going to use it?

Question Answering with Subgraph Embeddings

Introduction

• Open-domain Question Answering (Open QA) - efficiently querying large-scale knowledge base(KB) using natural language.
• Two main approaches:
  • Information Retrieval
    • Transform question (in natural language) into a valid query(in terms of KB) to get a broad set of candidate answers.
    • Perform fine-grained detection on candidate answers.
• Semantic Parsing
