Latent Semantic Learning with Structured Sparse Representation for Human Action Recognition

, 2011
This paper proposes a novel latent semantic learning method for extracting high-level features (i.e. latent semantics) from a large vocabulary of abundant mid-level features (i.e.

Image Captioning with multi-level similarity-guided semantic matching

Visual Informatics, 2021
Image Captioning is a cross-modal task that needs to automatically generate coherent natural sentences to describe the image contents. Due to the large gap between vision and language modalities, most of the existing methods have the problem of ...

Cross-Layer Security for Semantic Communications: Metrics and Optimization [PDF]

arXiv
Different from traditional secure communication that focuses on symbolic protection at the physical layer, semantic secure communication requires further attention to semantic-level task performance at the application layer. There is a research gap on how to comprehensively evaluate and optimize the security performance of semantic communication.

Exploring Textual Semantics Diversity for Image Transmission in Semantic Communication Systems using Visual Language Model [PDF]

arXiv
In recent years, the rapid development of machine learning has brought reforms and challenges to traditional communication systems. Semantic communication has appeared as an effective strategy to effectively extract relevant semantic signals semantic segmentation labels and image features for image transmission.

Bridging the Semantic Gap between RDF and SPARQL using Completeness Statements [Extended Version] [PDF]

arXiv, 2014
RDF data is often treated as incomplete, following the Open-World Assumption. On the other hand, SPARQL, the standard query language over RDF, usually follows the Closed-World Assumption, assuming RDF data to be complete. This gives rise to a semantic gap between RDF and SPARQL.
