NATURAL LANGUAGE PROCESSING (NLP) WEEKLY NEWSLETTER

NLP News Cypher U+007C 05.03.20

Freedom

Last week, so much happened. ICLR was a great digital turnout and there were tons of papers/code drops from the NLP community. As a result, this week’s newsletter is loaded to the gills.

And just when you thought we could rest from AI conferences…

Knowledge Graphs Are A’Boomin

Michael Galkin dropped U+1F525U+1F525U+1F525 this week. Per usual, after every major AI conference, Michael sums up the cream of the crop w/r/t graphs and NLP.

His TOC:

  1. Neural Reasoning for Complex QA with KGs
  2. KG-augmented Language Models
  3. KG Embeddings: Temporal and Inductive Inference
  4. Entity Matching with GNNs
  5. Bonus: KGs in Text RPGs!

Meena’s Heart in a Blender

A couple of months ago Google made headlines when they released “the world’s best” chatbot called Meena. Their code was never open-sourced. Well now it’s Facebook’s turn, and they’ve open-sourced their chatbot with 3 model sizes: 90M, 2.7B, and 9.4B. It’s called Blender.

You can try the 90M model here with our Colab of the week:

Google Colaboratory

Text-2-Tabular Data

Google drops BERT on retrieving tabular data with natural language. The takeaway is that instead of using traditional text-2-SQL type queries (which is difficult to scale across various tables), it uses BERT to encode the tables and questions as input. (FYI, rows, columns, and ranks get their own embedding!) This allows for better generalization.

How does it perform?

On the SQA dataset, it takes SOTA from 55.1 to 67.2!

With datasets WIKISQL and WIKITQ, it performs on par with the SOTA.

BLINK

If you’re looking for an entity linking python library you should check out Facebook’s BLINK. This is a two-stage model using first a retrieval bi-encoder to embed candidates' context and entity descriptions and then a cross-encoder in the 2nd stage. The library uses the 2019/08/01 Wikipedia dump as a knowledge base which means it takes up a hell lot of disk space. The codebase is easy to follow and set-up.

A Mosaic

The Allen Institute is doing the most interesting work in the reading comprehension/commonsense regions of NLP. They have great demos and I want to share with you COMeT, their event/commonsense knowledge graph. It’s pretty good, I queried “I went to the doctor’s office” and the graph generated intuitive reasons as to “why” I would go to the office. You should give it a whirl.

Dataset of the Week: HybridQA

What is it?

Dataset allows for multi-hop QA over tabular data. It contains over 70K question-answer pairs based on 13,000 tables, each table is in average linked to 44 passages.
