Image understanding and the web: a state-of-the-art review

Fariza Fauzi, Mohammed Belkhatir
2014 Journal of Intelligent Information Systems  
The contextual information of Web images is investigated to address the issue of characterizing their content with semantic descriptors and therefore bridge the semantic gap, i.e. the gap between their  ...  Such characterization allows for understanding the image content and is crucial in important Web-based tasks such as image indexing and retrieval.  ...  This feature is similar to the early fused concept-based models that loosely-couple textual and visual features where users can initially submit a text query and go on to select and view other visually  ...

Characterizing Users' Visual Analytic Activity for Insight Provenance

David Gotz, Michelle X. Zhou
2009 Information Visualization  
In turn, the action types can be used as the semantic building blocks for insight provenance.  ...  In addition, we define a taxonomy to categorize actions into three major classes based on their semantic intent.  ...  In this paper, we focus on the action tier, which uniquely bridges the gap between higher-level logical constructs and the lowest-level user interaction events.  ...

An Overview of Cross-media Retrieval: Concepts, Methodologies, Benchmarks and Challenges [article]

Yuxin Peng, Xin Huang, Yunzhen Zhao
2017 arXiv   pre-print
However, the requirements of users are highly flexible, such as retrieving the relevant audio clips with one query of image.  ...  Cross-media retrieval is designed for the scenarios where the queries and retrieval results are of different media types.  ...  feedback analysis is an auxiliary method for providing more information on user intent to promote the performance of retrieval.  ...
