The topology of a discussion: the #occupy case [PDF]

, 2014
We analyse a large sample of the Twitter activity developed around the social movement 'Occupy Wall Street' to study the complex interactions between the human communication activity and the semantic content of a discussion.

Semantic Community Portals

, 2007
Many virtual communities have surfaced and come together on the World Wide Web. Web-based community portals serve as a one-stop place for all information needs serving a group of users that have common interests. As organizations become highly dynamic and the people that join them become more geographically dispersed, the need for improved ways to ...

Communications Semantics for WSBPEL Processes [PDF]

2008 IEEE International Conference on Web Services, 2008
WSBPEL opens up the possibility of applying a range of formal techniques to the verification of Web service behaviors from two points of view: constraints between activities within the same process and dependencies between activities of different processes.

Advances and challenges in semantic communications: A systematic review

National Science Open, 2023
Inspired by the recent success of machine learning (ML), the concept of semantic communication introduced by Weaver in 1949 has gained significant attention and has become a promising research direction.

Toward Semantic Communications: Deep Learning-Based Image Semantic Coding

IEEE Journal on Selected Areas in Communications, 2023
Semantic communications has received growing interest since it can remarkably reduce the amount of data to be transmitted without missing critical information. Most existing works explore the semantic encoding and transmission for text and apply techniques in Natural Language Processing (NLP) to interpret the meaning of the text.

Analyzing image-text relations for semantic media adaptation and personalization [PDF]

, 2007
Progress in semantic media adaptation and personalisation requires that we know more about how different media types, such as texts and images, work together in multimedia communication.

Bringing communities to the semantic web and the semantic web to communities [PDF]

Proceedings of the 15th international conference on World Wide Web, 2006
In this paper we consider the types of community networks that are most often codified within the Semantic Web. We propose the recognition of a new structure which fulfils the definition of community used outside the Semantic Web. We argue that the properties inherent in a community allow additional processing to be done with the described ...

A survey on semantic communications: Technologies, solutions, applications and challenges

Digital Communications and Networks
Semantic Communication (SC) has emerged as a novel communication paradigm that provides a receiver with meaningful information extracted from the source to maximize information transmission throughput in wireless networks, beyond the theoretical capacity

Coming together to define membrane contact sites. [PDF]

, 2019
Close proximities between organelles have been described for decades. However, only recently a specific field dealing with organelle communication at membrane contact sites has gained wide acceptance, attracting scientists from multiple areas of cell ...

A Unified Approach to Semantic Information and Communication Based on Probabilistic Logic

IEEE Access, 2022
Traditionally, studies on technical communication (TC) are based on stochastic modeling and manipulation. This is not sufficient for semantic communication (SC) where semantic elements are logically connected, rather than stochastically correlated.
