Query: Multi-Modal Interaction Graph Convolutional Network for Temporal
  Language Localization in Videos   This paper focuses on tackling the problem of temporal language localization
in videos, which aims to identify the start and end points of a moment
described by a natural language sentence in an untrimmed video. However, it is
non-trivial since it requires not only the comprehensive understanding of the
video and sentence query, but also the accurate semantic correspondence capture
between them. Existing efforts are mainly centered on exploring the sequential
relation among video clips and query words to reason the video and sentence
query, neglecting the other intra-modal relations (e.g., semantic similarity
among video clips and syntactic dependency among the query words). Towards this
end, in this work, we propose a Multi-modal Interaction Graph Convolutional
Network (MIGCN), which jointly explores the complex intra-modal relations and
inter-modal interactions residing in the video and sentence query to facilitate
the understanding and semantic correspondence capture of the video and sentence
query. In addition, we devise an adaptive context-aware localization method,
where the context information is taken into the candidate moments and the
multi-scale fully connected layers are designed to rank and adjust the boundary
of the generated coarse candidate moments with different lengths. Extensive
experiments on Charades-STA and ActivityNet datasets demonstrate the promising
performance and superior efficiency of our model.
