# QA Readings
## [Memory Networks][memNet]

* Training
* Supervised by giving outputs for max function in 'O' and 'R'
* Train embedding matrices using SGD and margin loss ranking

## [End-to-End Memory Networks][EToEMemNet]

### [**Source Code][EToEMemNetSource]

## [Towards AI-Complete QA: A set of Prerequisite Toy Tasks][toyTasks]

* Dataset is self contained.
* Tasks come with both training and evaluation data
* These tasks can be generated by source code found [here](https://research.facebook.com/research/babi/)

## [Large-scale Simple QA with Memory Networks][largeScale]

* Training on multiple datasets had no negative results. Only improved performance
* Datasets:
* [Freebase](http://www.freebase.com)
* [WebQuestions](http://nlp.stanford.edu/software/sempre/)
* [Reverb](reverb.cs.washing.edu)
* This site includes source code
* [SimpleQuestions](https://research.facebook.com/research/babi)
* New dataset contributed by this paper

## [Ask Me Anything: Dynamic Memory Networking for NLP][AMA]

* Datasets
* Used the [toy tasks](https://research.facebook.com/research/babi/) mentioned above
* Concluded that Dynamic Memory Networks did well for general NLP structure

## [Key-Value Memory Networks for Directly Reading Documents][Key-Value]

* New approach of Key-Value MemNetworks made reading documents more viable
* Datasets:
* [MovieQA](https://research.facebook.com/research/babi/) ~ 100k questions in movie domain
* Knowledge Base formed from data available on [OmbdApi](http://omdbapi.com/)

## [Semantic Parsing via Staged Query Graph Generation][semanticGraph]

* Datasets
* [WebQuestions](http://nlp.stanford.edu/software/sempre/) mentioned above
* Evaluated results with the [SEMPRE](http://www-nlp.stanford.edu/software/sempre/)
* Semantic parsing is reduced to graph query generation, formulated as a staged search problem
* Leverages KB at an early stage to prune search space

## [The Value of Semantic Parse Labeling for KBQA][semanticValue]

* Datasets
* [WebQuestionsSP](https://www.microsoft.com/en-us/download/details.aspx?id=52763)
* Learning from labeled semantic parses significantly improves overall performance
* Can obtain semantic parses with high accuracy and at a cost comparable to obtaining just the answers

## [QA with Subgraph Enbeddings][subgraph]

* Datasets
* Trained with [FreeBase](http://www.freebase.com)
* Tested on [WebQuestions](http://nlp.stanford.edu/software/sempre/)
* Very weak performance, peaked at 41.8 F1 score, but the best (so far) with no human interaction.

## [Open QA with Weakly Supervised Embedding Models][openWeak]

* Databases
* [DBPedia](http://wiki.dbpedia.org/)
* [WebQuestions](http://nlp.stanford.edu/software/sempre/)
* Learn to map questions to vectorial feature representations
* Allows use of any KB without a required lexicon or grammar
* All variations greatly improved upon [Paralex](http://www.aclweb.org/anthology/P13-1158)
