Definition: 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].

Positive Example 1 -
Input: Este artículo no es un artículo de investigación, ya que sólo muestra cómo programar un robot mediante la herramienta de lógica difusa. Este tema ya ha sido propuesto como solución en navegación de robots.

Positive Example 2 -
Input: I don't think the work reported in this paper is suitable for the SCCC conference. The author should consider reporting this experience on a conference more focused on practice in computer engineering than in CS reserarch. The material presented in the paper could be of interest for practicioners working with Oracle, namely a particular product.
Output: en

Now complete the following example -
Input: This paper proposes the graph convolutional networks, motivated from approximating graph convolutions.  In one propagation step, what the model does can be simplified as, first linearly transform the node representations for each node, and then multiply the transformed node representations with the normalized affinity matrix (with self-connections added), and then pass through nonlinearity.  This model is used for semi-supervised learning on graphs, and in the experiments it demonstrated quite impressive results compared to other baselines, outperforming them by a significant margin.  The evaluation of propagation model is also interesting, where different variants of the model and design decisions are evaluated and compared.  It is surprising that such a simple model works so much better than all the baselines.  Considering that the model used is just a two-layer model in most experiments, this is really surprising as a two-layer model is very local, and the output of a node can only be affected by nodes in a 2-hop neighborhood, and no longer range interactions can play any roles in this.  Since computation is quite efficient (sec. 6.3), I wonder if adding more layers helped anything or not.  Even though motivated from graph convolutions, when simplified as the paper suggests, the operations the model does are quite simple.  Compared to Duvenaud et al. 2015 and Li et al. 2016, the proposed method is simpler and does almost strictly less things.  So how would the proposed GCN compare against these methods?  Overall I think this model is simple, but the connection to graph convolutions is interesting, and the experiment results are quite good.  There are a few questions that still remain, but I feel this paper can be accepted.
