Project Profile

Project abbreviation: MIC 21

Project name: Multilingual Image Corpus 2021

Project coordinator: Prof. Svetla Koeva

Project consortium: Institute for Bulgarian Language “Prof. Lyubomir Andreychin”

Funding: ELG (European Language Grid) Pilot Projects Open Call 2

Project duration: 01.03.2021 - 28.02.2022

Main key words: image dataset, ontology of visual objects

Background of the research topic: One of the processing tasks for large multimodal data streams is automatic image description (image classification, object segmentation and classification). Although the number and the diversity of image datasets is constantly expanding still there is a huge demand for more datasets in terms of variety of domains and object classes covered.

Goal of the project: The goal of the project Multilingual Image Corpus (MIC 21) is to provide a large image dataset with annotated objects and object descriptions in (at least) 20 European languages.

Project abstract: The Multilingual Image Corpus consists of an Ontology of visual objects (based on WordNet) and a collection of thematically related images whose objects are annotated with segmentation masks and labels describing the ontology classes. The dataset is designed both for image classification and object detection and for semantic segmentation. The main contributions of our work are: a) the provision of large collection of high-quality copyright free images; b) the formulation of the Ontology of visual objects based on WordNet noun hierarchies; c) the precise manual correction of automatic object segmentation within the images and the annotation of object classes; and d) the association of objects and images with extended multilingual descriptions based on WordNet inner- and interlingual relations.
