Kurzfassung
We address the task of labeling image-sentence pair at large-scale
with varied concepts representing connotations. That is for any
given query image-sentence, we aim to annotate them with the
connotations that capture intrinsic intension. To achieve it, we pro-
pose a Connotation multimodal embedding model (CMEM) with a
novel loss function. Its unique characteristics over previous models
include (i) can leverage multimodal data as opposed to only visual
information, (ii) robust to outlier labels in a multi-label scenario
and (iii) works well with large-scale weakly supervised data. 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 images
with connotation labels, our byproduct of the model inherently
supports cross-modal retrieval.
