On the Quantification of the Mental Image of Visual Concepts for Multi-modal Applications On the Quantification of the Mental Image of Visual Concepts for Multi-modal Applications Marc, A.

It is an yet solved issue for multimedia applications like image captioning, where it is often challenging to select the best fitting wording out of a group of candidates. To create a measurement for the perceived differences between words, this doctoral research proposes the idea of analyzing crawled image data to gain a better semantic understanding of language and vision. Abstract words have a broad mental image due to them being less visually defined, while concrete words with a rather narrow visual feature space are visually easier to grasp. The core goal of this research is to approximate this perceived abstractness of those words as a metric. The thesis proposes two methods, looking at both relative and absolute measurements. For the relative method, a data-driven approach is proposed, while the absolute measurements train a machine-learned model on existing data from Psycholinguistics. Each method is evaluated using crowd-sourced data and compared to related approaches. With this, the thesis presents methods to analyze the mental image of words from different angles, targeting a way to quantify the semantic gap between vision and language.
