Polish Corpus of Annotated Descriptions of Images

The paper presents a new dataset of image descriptions in Polish. The descriptions are morphosyntactically analysed and the pairs of these descriptions are annotated in terms of semantic relatedness and entailment. All annotations are provided by human annotators with strong linguistic background. The dataset can be used for evaluation of various systems integrating language and vision. It is applicable for evaluation of systems designed to image generation based on provided descriptions (text-to-image generation) or to caption generation based on images (image-to-text generation). Furthermore, as selected images are split into thematic groups, the dataset is also useful for validating image classification approaches.
