Growth of multimodal content on the web and social media has generated abundant weakly aligned image-sentence pairs. However, it is hard to interpret them directly due to intrinsic "intension". In this paper, we aim to annotate such image-sentence pairs with connotations as labels to capture the intrinsic "intension". We achieve it with a connotation multimodal embedding model (CMEM) using a novel loss function. It's unique characteristics over previous models include: (i) the exploitation of

With extensive quantitative evaluation, we exhibit the effectiveness of CMEM for detection of multiple labels over other state-of-the-art approaches. Also, we show that in addition to annotation of image-sentence pairs with connotation labels, byproduct of our model inherently supports cross-modal retrieval i.e. image query -sentence retrieval.
