Web principles, access and processing methods, thus shielding users and developers from the underlying complexities.  ...  The Web has long exceeded its original purpose of a distributed hypertext system and has become a global, data sharing and processing platform.  ...  Therefore, the burden of updating the indexes is lifted to enable a much higher throughput of insert and a faster query speed.  ...

State-of-the-art on clustering data streams

Mohammed Ghesmoune, Mustapha Lebbah, Hanene Azzag
2016 Big Data Analytics  
This paper presents a comprehensive survey of the data stream clustering methods and an overview of the most well-known streaming platforms which implement clustering.  ...  In the literature of data stream clustering methods, a large number of algorithms use a two-phase scheme which consists of an online component that processes data stream points and produces summary statistics  ...  All authors read and approved the final manuscript. Competing interests The authors declare that they have no competing interests.  ...

Data synthesis in the Community Land Model for ecosystem simulation

Hongsheng He, Dali Wang, Yang Xu, Jindong Tan
2016 Journal of Computational Science  
Because the relation of variables in the ecosystem depends on sampling time and frequencies, a region of interest (ROI) is determined using a sliding window on time series with a predefined sampling point  ...  Within each ROI, system variables are clustered in accordance with a group of selective features by a combination of Affinity Propagation and k-Nearest-Neighbor.  ...  This paper utilizes machine learning algorithms to better understand the behavior of the geosystem and to bridge the gap between the geosystem simulation and onsite observation.  ...

Improving search in tele-lecturing

Franka Moritz, Maria Siebert, Christoph Meinel
2011 Proceedings of the International Conference on Web Intelligence, Mining and Semantics - WIMS '11  
Tele-teaching, where recorded lectures are streamed via the internet, was identified as the easiest adoptable method to produce large amounts of e-learning content.  ...  Due to the nature of the e-learning material produced, it is lacking searchable data and metadata.  ...  Therefore, we are suggesting a method that leverages keywords that are inserted into our system, either by information retrieval or user participation.  ...

Pattern Matching Techniques for Replacing Missing Sections of Audio Streamed across Wireless Networks

Jonathan Doherty, Kevin Curran, Paul McKevitt
2015 ACM Transactions on Intelligent Systems and Technology  
One method overlooked to date, which can work alongside existing audio compression schemes, is that which takes into account the semantics and natural repetition of music.  ...  Whenever dropouts occur, SoFI swaps audio presented to the listener between a live stream and previous sections of the audio stored locally.  ...  Traditional ARQ [Lin et al. 1984] methods have been improved with the use of gap detection in packets where a large number of packets in sequence are lost.  ...
