In this task, you are given a paper review. Based on the review, your job is to identify language and generate "en" if the review is in English or generate "es" if the review is in Spanish. Note that URLs in the text have been replaced with [Link].

This paper introduces a new approach to semantic parsing in which the model is equipped with a neural sequence to sequence (seq2seq) model (referred to as the “programmer”) which encodes a natural language question and produces a program. The programmer is also equipped with a ‘key variable’ memory component which stores (a) entities in the questions (b) values of intermediate variables formed during execution of intermediate programs. These variables are referred to further build the program.                    The model is also equipped with certain discrete operations (such as argmax or 'hop to next edges in a KB'). A separate component ("interpreter/computer") executes these operations and stores intermediate values (as explained before). Since the ‘programmer' is inherently a seq2seq model, the "interpreter/computer” also acts as a syntax/type checker only allowing the decoder to generate valid tokens. For example, the second argument to the “hop” operation has to be a KB predicate. Finally the model is trained with weak supervision and directly optimizes the metric which is used to evaluate the performance (F score). Because of the discrete operations and the non differentiable reward functions, the model is trained with policy gradients (REINFORCE). Since gradients obtained through REINFORCE have high variance, it is common to first pretrain the model with a max-likelihood objective or find some good sequences of actions trained through some auxiliary objective. This paper takes a latter approach in which it finds good sequences via an iterative maximum likelihood approach. The results and discussion sections are presented in a very nice way and the model achieves SOTA results on the WebQuestions dataset when compared to other weakly supervised model.  The paper is written clearly and is very easy to follow.  This paper presents a new and exciting direction and there is scope for a lot of future research in this direction. I would definitely love to see this presented in the conference.  Questions for the authors (important ones first)  1. Another alternative way of training the model would be to bootstrap the parameters (\theta) from the iterative ML method instead of adding pseudo gold programs in the beam (Line 510 would be deleted). Did you try that and if so why do you think it didn’t work? 2. What was the baseline model in REINFORCE. Did you have a separate network which predicts the value function. This must be discussed in the paper in detail. 3. Were there programs which required multiple hop operations? Or were they limited to single hops. If there were, can you provide an example? (I will understand if you are bound by word limit of the response) 4. Can you give an example where the filter operation would be used? 5. I did not follow the motivation behind replacing the entities in the question with special ENT symbol  Minor comments: Line 161 describe -> describing Line 318 decoder reads ‘)’ -> decoder generates ‘)'

Es un artículo que presenta un tema novedoso en el área de la Ingeniería de Software. El artículo está muy bien documentado y fundamentado. Las tecnologías utilizadas en el desarrollo del prototipo son de interés actual.  Como lo describe el artículo, se trata de un primer paso en una línea de investigación y del desarrollo de un prototipo de una aplicación meta-case. Queda es este sentido, poco clara cual es el nivel de madurez actual, tanto de la investigación como de la aplicación desarrollada.

-          Ambicioso en el título, logros expuestos en el artículo más bien moderados.  -          Referencia de TOGAF es cuestionable en el tenor del artículo.  -          Cómo se seleccionaron los modelos de referencia??? Qué otros modelos existen y no fueron considerados??
