Will Graph Data Management Techniques Contribute to the Successful Large-Scale Deployment of Semantic Web Technologies?
Found in: 2012 IEEE International Conference on Data Engineering Workshops (ICDEW)
By Philippe Cudre-Mauroux
Issue Date:April 2012
pp. 213-215
The Semantic Web vision ambitions to create a large-scale, interconnected Web of machine-processable data in addition to the current Web of documents currently available online. Its most recent and visible incarnation -- the Linked Data movement1 -- is bas...
Probabilistic Message Passing in Peer Data Management Systems
Found in: Data Engineering, International Conference on
By Philippe Cudre-Mauroux, Karl Aberer, Andras Feher
Issue Date:April 2006
pp. 41
Until recently, most data integration techniques involved central components, e.g., global schemas, to enable transparent access to heterogeneous databases. Today, however, with the democratization of tools facilitating knowledge elicitation in machine-pro...
Scalable Anomaly Detection for Smart City Infrastructure Networks
Found in: IEEE Internet Computing
By Djellel Eddine Difallah,Philippe Cudre-Mauroux,Sean A. McKenna
Issue Date:November 2013
pp. 39-47
Dynamically detecting anomalies can be difficult in very large-scale infrastructure networks. The authors' approach addresses spatiotemporal anomaly detection in a smarter city context with large numbers of sensors deployed. They propose a scalable, hybrid...
GridVine: An Infrastructure for Peer Information Management
Found in: IEEE Internet Computing
By Philippe Cudré-Mauroux, Suchit Agarwal, Karl Aberer
Issue Date:September 2007
pp. 36-44
GridVine is a semantic overlay infrastructure based on a peer-to-peer (P2P) access structure. Built following the principle of data independence, it separates a logical layer—in which data, schemas, and schema mappings are managed—from ...
Efficient Versioning for Scientific Array Databases
Found in: Data Engineering, International Conference on
By Adam Seering,Philippe Cudre-Mauroux,Samuel Madden,Michael Stonebraker
Issue Date:April 2012
pp. 1013-1024
In this paper, we describe a versioned database storage manager we are developing for the SciDB scientific database. The system is designed to efficiently store and retrieve array-oriented data, exposing a ``no-overwrite'' storage model in which each updat...
TrajStore: An adaptive storage system for very large trajectory data sets
Found in: Data Engineering, International Conference on
By Philippe Cudre-Mauroux, Eugene Wu, Samuel Madden
Issue Date:March 2010
pp. 109-120
The rise of GPS and broadband-speed wireless devices has led to tremendous excitement about a range of applications broadly characterized as “location based services”. Current database storage systems, however, are inadequate for manipulating the very larg...
Hybrid graph and relational query processing in main memory
Found in: 2013 IEEE 29th International Conference on Data Engineering Workshops (ICDEW)
By Martin Grund,Philippe Cudre-Mauroux,Jens Krueger,Hasso Plattner
Issue Date:April 2013
pp. 23-24
Modern enterprise applications are a challenge for traditional database systems. In the recent years, enterprise workloads evolved from simple lookups and updates to complex queries integrating both analytical and transactional data. In addition, graph str...
Benchmarking OLTP/web databases in the cloud: the OLTP-bench framework
Found in: Proceedings of the fourth international workshop on Cloud data management (CloudDB '12)
By Andrew Pavlo, Carlo A. Curino, Djellel E. Difallah, Philippe Cudre-Mauroux
Issue Date:October 2012
pp. 17-20
Benchmarking is a key activity in building and tuning data management systems, but the lack of reference workloads and a common platform makes it a time consuming and painful task. The need for such a tool is heightened with the advent of cloud computing--...
ZenCrowd: leveraging probabilistic reasoning and crowdsourcing techniques for large-scale entity linking
Found in: Proceedings of the 21st international conference on World Wide Web (WWW '12)
By Philippe Cudre-Mauroux, Djellel Eddine Difallah, Gianluca Demartini
Issue Date:April 2012
pp. 469-478
We tackle the problem of entity linking for large collections of online pages; Our system, ZenCrowd, identifies entities from natural language text using state of the art techniques and automatically connects them to the Linked Open Data cloud. We show how...
To tag or not to tag -: harvesting adjacent metadata in large-scale tagging systems
Found in: Proceedings of the 31st annual international ACM SIGIR conference on Research and development in information retrieval (SIGIR '08)
By Adriana Budura, Karl Aberer, Philippe Cudre-Mauroux, Sebastian Michel
Issue Date:July 2008
pp. 2-2
We present HAMLET, a suite of principles, scoring models and algorithms to automatically propagate metadata along edges in a document neighborhood. As a showcase scenario we consider tag prediction in community-based Web 2.0 tagging applications. Experimen...
The chatty web: emergent semantics through gossiping
Found in: Proceedings of the twelfth international conference on World Wide Web (WWW '03)
By Karl Aberer, Manfred Hauswirth, Philippe Cudre-Mauroux
Issue Date:May 2003
pp. 197-206
This paper describes a novel approach for obtaining semantic interoperability among data sources in a bottom-up, semi-automatic manner without relying on pre-existing, global semantic models. We assume that large amounts of data exist that have been organi...
