Because our manipulated descriptions form minimal pairs with the reference descriptions, we are able to assess the impact of different kinds of errors on the perceived quality of the descriptions.
Human assessment remains the most trusted form of evaluation in NLG, but highly diverse approaches and a proliferation of different quality criteria used by researchers make it difficult to compare results and draw conclusions across papers, with adverse implications for meta-evaluation and reproducibility.
While useful, these evaluations do not tell us anything about the kinds of image descriptions that systems are able to produce.
NLG researchers often use uncontrolled corpora to train and evaluate their systems, using textual similarity metrics, such as BLEU.

We observe a severe under-reporting of the different kinds of errors that Natural Language Generation systems make.
By applying this framework to the GEM generation benchmark, we propose an evaluation suite made of 80 challenge sets, demonstrate the kinds of analyses that it enables and shed light onto the limits of current generation models.

We introduce GEM, a living benchmark for natural language Generation (NLG), its Evaluation, and Metrics.

Automatic image description systems are commonly trained and evaluated using crowdsourced, human-generated image descriptions.
Task effects in NLG corpus elicitation recently started to receive more attention, but are usually not modeled statistically.
Currently, there is little agreement as to how Natural Language Generation (NLG) systems should be evaluated.
In contrast, recent neural models for data-to-text generation have been proposed as end-to-end approaches, where the non-linguistic input is rendered in natural language with much less explicit intermediate representations in-between.

This taxonomy serves as a reference point to think about how other people should be described, and can be used to classify and compute statistics about labels applied to people.
We present a corpus of spoken Dutch image descriptions, paired with two sets of eye-tracking data: Free viewing, where participants look at images without any particular purpose, and Description viewing, where we track eye movements while participants produce spoken descriptions of the images they are viewing.
Automatic image description systems typically produce generic sentences that only make use of a small subset of the vocabulary available to them.
This paper discusses the need for a dictionary of affixal negations and regular antonyms to facilitate their automatic detection in text.
We provide a qualitative analysis of the descriptions containing negations (no, not, n't, nobody, etc) in the Flickr30K corpus, and a categorization of negation uses.
An untested assumption behind the crowdsourced descriptions of the images in the Flickr30K dataset (Young et al., 2014) is that they "focus only on the information that can be obtained from the image alone" (Hodosh et al., 2013, p. 859).
The main goal of this study is to find out (i) whether it is feasible to collect keywords for a large collection of sounds through crowdsourcing, and (ii) how people talk about sounds, and what information they can infer from hearing a sound in isolation.
