TripleWave: Spreading RDF Streams on the Web [chapter]

Andrea Mauri, Jean-Paul Calbimonte, Daniele Dell'Aglio, Marco Balduini, Marco Brambilla, Emanuele Della Valle, Karl Aberer
2016 Lecture Notes in Computer Science  
Research in these areas has proposed an ecosystem of solutions to query, reason and perform real-time processing over heterogeneous and distributed data streams on the Web.  ...  Processing data streams is increasingly gaining momentum, given the need to process these flows of information in real-time and at Web scale.  ...  The Semantic Web community has studied the problems associated with the processing of and reasoning over these complex streams of data, leading to the emergence of RDF Stream Processing and Stream Reasoning  ...

Multi-stream portrait of the cosmic web

Nesar S. Ramachandra, Sergei F. Shandarin
2015 Monthly notices of the Royal Astronomical Society  
At the resolution of the simulation i.e. without additional smoothing, the cosmic web represents a hierarchical structure: each halo is embedded in the filamentary framework of the web predominantly at  ...  the filament crossings, and each filament is embedded in the wall like fabric of the web at the wall crossings.  ...  ACKNOWLEDGEMENTS The authors are grateful to Gustavo Yepes and Noam Libeskind for providing the simulations used in this study and the Sir John Templeton Foundation for the support.  ...

Fast topic discovery from web search streams

Di Jiang, Kenneth Wai-Ting Leung, Wilfred Ng
2014 Proceedings of the 23rd international conference on World wide web - WWW '14  
Web search involves voluminous data streams that record millions of users' interactions with the search engine.  ...  Hence, they are increasingly ineffective in the face of the ever-increasing web search data that accumulate in the format of online streams.  ...  [1] presented a scalable parallel framework for efficient inference in latent variable models over streaming web-scale data.  ...

Efficient RDF stream reasoning with graphics processingunits (GPUs)

Chang Liu, Jacopo Urbani, Guilin Qi
2014 Proceedings of the 23rd International Conference on World Wide Web - WWW '14 Companion  
In this paper, we study the problem of stream reasoning and propose a reasoning approach over large amounts of RDF data, which uses graphics processing units (GPU) to improve the performance.  ...  First, we show how the problem of stream reasoning can be reduced to a temporal reasoning problem. Then, we describe a number of algorithms to perform stream reasoning with GPUs.  ...  Acknowledge Guilin Qi is partially supported by the Marie Curie IRSES project SemData 612551.

Two-stream indexing for spoken web search

Jitendra Ajmera, Anupam Joshi, Sougata Mukherjea, Nitendra Rajput, Shrey Sahay, Mayank Shrivastava, Kundan Srivastava
2011 Proceedings of the 20th international conference companion on World wide web - WWW '11  
This paper presents two-stream processing of audio to index the audio content for Spoken Web search. The first stream indexes the meta-data associated with a particular audio document.  ...  The results suggest significant improvement over a meta-data-only or a speech-recognitiononly system, thus justifying the two-stream processing approach.  ...  At a reasonable recall level, however, it is very clear that the two stream processing performs far better than either of the processing technique.  ...

Topical anomaly detection from Twitter stream

Pramod Anantharam, Krishnaprasad Thirunarayan, Amit Sheth
2012 Proceedings of the 3rd Annual ACM Web Science Conference on - WebSci '12  
In this paper, we spot topically anomalous tweets in twitter streams by analyzing the content of the document pointed to by the URLs in the tweets in preference to their textual content.  ...  Specifically, we determine the divergence of claimed topic of a tweet as reflected by the hashtags and the actual topic as reflected by the referenced document content.  ...  ACKNOWLEDGMENTS We thank the twitris team (http://twitris.knoesis.org) for providing data for our evaluations. We thank Wenbo Wang, Lu  ...

A Streaming Real-Time Web Observatory Architecture for Monitoring the Health of Social Machines

Ramine Tinati, Xin Wang, Ian Brown, Thanassis Tiropanis, Wendy Hall
2015 Proceedings of the 24th International Conference on World Wide Web - WWW '15 Companion  
Over the past years, streaming Web services have become popular, with many of the top Web platforms now offering near real-time streams of user and machine activity.  ...  In light of this, Web Observatories now are faced with the challenge of being able to process and republish real-time, big data, Web streams, whilst maintaining access control and data consistency.  ...  We then describe the Web Observatory API and use of OAuth 2.0 as a security mechanism to provide data owners control over who has access to their data.  ...

Thu-Le Pham, Muhammad Intizar Ali, Alessandra Mileo, Daniele Dell'Aglio, Thomas Eiter, Fredrik Heintz, Danh Le Phuoc, Daniele Dell Aglio, Thomas Eiter, Fredrik Heintz, Danh Le Phuoc
2019 Semantic Web Journal  
In this scenario, in order to reduce the amount of data to reason upon at each iteration, we can leverage advances in continuous query processing over Semantic Web streams.  ...  The exponential growth in the availability of streaming data on the Web has seriously hindered the applicability of state-ofthe-art expressive reasoners, limiting their applicability to process streaming  ...  over the logic-based stream reasoner.  ...
