This study explores the feasibility of performing Chinese word segmentation (CWS) and POS tagging by deep learning. We try to avoid task-specific feature engineering, and use deep layers of neural networks to discover relevant features to the tasks. We leverage large-scale unlabeled data to improve internal representation of Chinese characters, and use(More)
Trust plays a central role for efficient and secure interactions on the Semantic Web. Nowadays, more and more research has focused on this topic. In this paper, we introduce RCSW, a Reputation-Chain trust model for the Semantic Web. We illustrate the basic definitions and mechanisms of RCSW and present the algorithm to calculate trust ratings through the(More)
Most of today's web content is designed for human consumption, which makes it difficult for software tools to access them readily. Even web content that is automatically generated from back-end databases is usually presented without the original structural information. In this paper, we present an automated information extraction algorithm that can extract(More)
Nowadays, more and more research has focused on the trust management of the Semantic Web. Some mature technologies from many fields such as multi-agent systems, social network analysis and artificial intelligence have been introduced to this field. However, some unique characteristics of the Semantic Web are more or less ignored. In this paper, we try to(More)
The Semantic Web, conceived as a collection of agents, brings new opportunities and challenges to trust research. Enabling trust to ensure more effective and efficient interaction is at the heart of the Semantic Web vision. We propose a composite trust model based on statistical decision theory and Bayesian sequential analysis to balance the costs and(More)
Enabling trust to ensure more effective and efficient agent interaction is at the heart of the Semantic Web vision. We propose a computational trust model based on Bayesian decision theory in this paper. Our trust model combines a variety of sources of information to assist users with making correct decision in choosing the appropriate providers according(More)

Many Semantic Web applications require the integration of data from distributed and autonomous RDF data sources. However, the values in the RDF triples would be frequently recorded simply as the literal, and additional contextual information such as unit and format is often omitted, relying on consistent understanding of the context. In the wider context of(More)
