To tag or not to tag -

Adriana Budura, Sebastian Michel, Philippe Cudré-Mauroux, Karl Aberer
2008 Proceedings of the 31st annual international ACM SIGIR conference on Research and development in information retrieval - SIGIR '08  
To the best of our knowledge, HAMLET is the first system to promote an efficient and precise reuse of shared metadata in highly dynamic, large-scale Web 2.0 tagging systems.  ...  Experiments using real-world data demonstrate the viability of our approach in large-scale environments where tags are scarce.  ...  We put forward HAMLET (Harvesting Adjacent Metadata in Large-ScalE Tagging Systems), a suite of principles, scoring models and algorithms for metadata propagation.  ...

Harvesting social knowledge from folksonomies

Harris Wu, Mohammad Zubair, Kurt Maly
2006 Proceedings of the seventeenth conference on Hypertext and hypermedia - HYPERTEXT '06  
Collaborative tagging systems, or folksonomies, have the potential of becoming technological infrastructure to support knowledge management activities in an organization or a society.  ...  This paper presents designs that enhance collaborative tagging systems to meet some key challenges: community identification, ontology generation, user and document recommendation.  ...  The tags in some large tagging systems have become non-navigable and not even searchable due to the sheer volume of the tags/documents and the low quality of the tags.  ...

Beyond Pixels: Image Provenance Analysis Leveraging Metadata [article]

Aparna Bharati, Daniel Moreira, Joel Brogan, Patricia Hale, Kevin W. Bowyer, Patrick J. Flynn, Anderson Rocha, Walter J. Scheirer
2019 arXiv   pre-print
Creative works, whether paintings or memes, follow unique journeys that result in their final form.  ...  Most current works seek to build provenance graphs based on the shared content between images or videos.  ...  In addition to that, most of them only consider two images to form a composite, thereby limiting the solutions for large-scale general applicability.  ...

Improving Discovery of Open Civic Data

Sara Lafia, Andrew Turner, Werner Kuhn, Michael Wagner
2018 International Conference Geographic Information Science  
Metadata about civic data (such as thematic categories, user-generated tags, geo-references, or attribute schemata) primarily rely on technical vocabularies that reflect scientific or organizational hierarchies  ...  In similar situations, it has been beneficial to augment official metadata with semantic annotations that expand the discoverability and relevance recommendations of data, supporting more inclusive access  ...  Section 4 discusses the method developed to enrich tags during metadata harvesting. Section 5 describes the resulting implementation.  ...

Automated Annotation of Landmark Images Using Community Contributed Datasets and Web Resources [chapter]

Gareth J. F. Jones, Daragh Byrne, Mark Hughes, Noel E. O'Connor, Andrew Salway
2011 Lecture Notes in Computer Science  
The system then takes advantage of the information written about landmarks available on the web at large to extract a fact about the landmark in the image.  ...  Given an image with GPS data of its location of capture, our system returns a semantically-rich annotation comprising tags which both identify the landmark in the image, and provide an interesting fact  ...  Acknowledgement The research reported in this paper is part of the project TRIPOD supported by the European commission under contract No. 045335.  ...

Neighborhood-Based Tag Prediction [chapter]

Adriana Budura, Sebastian Michel, Philippe Cudré-Mauroux, Karl Aberer
2009 Lecture Notes in Computer Science  
Experiments using real-world data demonstrate the viability of our approach in large-scale environments where tags are scarce.  ...  We consider the problem of tag prediction in collaborative tagging systems where users share and annotate resources on the Web.  ...  We put forward HAMLET (Harvesting Adjacent Metadata in Large-ScalE Tagging Systems), a suite of principles, scoring models and algorithms for metadata propagation.  ...

Exploring place through user-generated content: Using Flickr to describe city cores

Ross Purves, Livia Hollenstein
2010 Journal of Spatial Information Science  
Here, we explore such language by harvesting georeferenced and tagged metadata associated with 8 million Flickr images and thus consider how large numbers of people name city core areas.  ...  Terms used to describe city centers, such as Downtown, are key concepts in everyday or vernacular language.  ...  Jo Wood, David Mark, Clair Davies, and Alistair Edwardes are thanked for useful suggestions with respect to this research.  ...

Serendip: Topic model-driven visual exploration of text corpora

Eric Alexander, Joe Kohlmann, Robin Valenza, Michael Witmore, Michael Gleicher
2014 2014 IEEE Conference on Visual Analytics Science and Technology (VAST)  
In implementing this approach into a tool called Serendip, we incorporate topic model data and metadata into a highly reorderable matrix to expose corpus level trends; extend encodings of tagged text to  ...  Abstract-Exploration and discovery in a large text corpus requires investigation at multiple levels of abstraction, from a zoomed-out view of the entire corpus down to close-ups of individual passages  ...  A system needs to scale to large numbers of large documents (e.g. books and plays).  ...

2009 Proceedings of the 7th international conference on Mobile systems, applications, and services - Mobisys '09  
Furthermore, deployments that support pervasive computing raise additional issues related to user acceptance and system utility.  ...  Users need expert guidance to effectively mount their tags and are encouraged by compelling applications to wear tags more frequently.  ...  ACKNOWLEDGEMENTS We like to thank Garret Cole, Sam Raymer, and Julia Schwarz for their excellent work in support of the RFID Ecosystem project and its applications.  ...

The Changing Ocean and the Impact of Technology: The Role of the Ocean Tracking Network [chapter]

Frederick Whoriskey
2019 The Future of Ocean Governance and Capacity Development  
Repeated small-scale oil spills occurred,2 fouling beaches and having undocumented consequences for the area's ecology. Plastic waste began to pile up on the shore, and the ocean began warming.  ...  Within ten years, most of these species were gone, and the few that remained were greatly reduced in numbers, most probably falling victim to overharvesting.  ...  However, the ocean story is not one of total gloom and loss. The environmental movement that developed in the wake of large-scale environmental damage changed public policy and regulatory regimes.  ...

of music auto-tagging by 7% in a real-world setting.  ...  Researchers typically obtain music tags from the Internet and use them to construct machine learning models. Nevertheless, such tags are usually noisy and sparse.  ...  ACKNOWLEDGMENTS The authors would like to thank the anonymous reviewers for valuable comments that improved the quality of this paper.  ...

In addition, we detail design patterns for tangibles of varying complexity and interactive capabilities, including the ability to sense orientation on the mat, harvest power, provide additional input and  ...  Different tag designs can be used to determine rotation (d), stack objects (e), provide I/O (f), and extend sensing outside the bounds of the Mat (g).  ...  Both processes result in a material which is flexible, but not stretchable-this is not a problem as this layer does not need to stretch or compress, as long as other layers around it are able to do so.  ...
