Towards Semantically-Interlinked Online Communities
This work presents the SIOC ontology which combines terms from vocabularies that already exist with new terms needed to describe the relationships between concepts in the realm of online community sites. Expand
Optimized transformer design: inclusive of high-frequency effects
Switching circuits, operating at high frequencies, have led to considerable reductions in the size of magnetic components and power supplies. Nonsinusoidal voltage and current waveforms andExpand
Optimizing the AC resistance of multilayer transformer windings with arbitrary current waveforms
AC losses due to nonsinusoidal current waveforms have been found by calculating the losses at harmonic frequencies when the Fourier coefficients are known. An optimized foil or layer thickness in aExpand
Crowdsourcing, citizen sensing and sensor web technologies for public and environmental health surveillance and crisis management: trends, OGC standards and application examples
An in-depth review of the key issues and trends in these areas, the challenges faced when reasoning and making decisions with real-time crowdsourced data, the core technologies and Open Geospatial Consortium standards involved (Sensor Web Enablement and Open GeoSMS), as well as a few outstanding project implementation examples from around the world.

A Hierarchical Model of Reviews for Aspect-based Sentiment Analysis
It is shown that the hierarchical model outperforms two non-hierarchical baselines, obtains results competitive with the state-of-the-art, and outperforms the state of the art on five multilingual, multi-domain datasets without any hand-engineered features or external resources. Expand
Understanding how Twitter is used to spread scientific messages
To understand how Twitter is practically used for spreading scientic messages, tweets containing the ocial hashtags of #scientic messages were captured in order to understand how the social network is used for spread information. Expand
The Future of Social Networks on the Internet: The Need for Semantics
This paper argues that the semantic Web is a useful platform for linking and for performing operations on diverse person-and object-related data gathered from heterogeneous social networking sites, and that object-centered networks can serve as rich data sources for semantic Web applications. Expand
Interlinking the Social Web with Semantics
This paper deals with applying semantic Web technologies to the social Web can lead to a social semantic Web, creating a network of interlinked and semantically rich knowledge. One of the mostExpand
Online Social and Business Networking Communities
A classification schema for the main types of social networking sites is suggested and an evaluation in terms of features and functionality is conducted. Expand
Opinion Mining and Sentiment Polarity on Twitter and Correlation between Events and Sentiment
A positive or negative sentiment on Twitter posts is provided using a well-known machine learning method for text categorization using manually labeled (positive/negative) tweets to build a trained method to accomplish a task. Expand
