Abstract Social media can be a double-edged sword for society, either as convenient channel exchanging ideas or an unexpected conduit circulating fake news through large population. While existing studies of focus on theoretical modeling propagation identification methods based machine learning, it is important to understand the realistic mechanisms between models and black-box methods. Here we track databases real in both, Weibo China Twitter Japan from different cultures, which include...
Social media can be a double-edged sword for society, either as convenient channel exchanging ideas or an unexpected conduit circulating fake news through large population.

Here we track databases real in both, Weibo China Twitter Japan from different culture, which include their...
Given that the important information of technological innovation contained in outlier patents can provide first-hand data for enterprises to carry out activities efficiently, we rely on multi-dimensional map construct a path identify opportunities based patents. [Methods]Firstly, BERT-LOF algorithm (Local Outlier Factor) is used extract candidate patents, and entropy weight method assign weights indicators novelty, scope application, development capability calculate comprehensive assessment...
Fake news causes an adverse effect on the regular public order and has become easier to propagate with popularity of online social networks. The threat fake propagation makes it important explore vital nodes, which are defined as nodes large branch sizes hence generating a wider influence than others in this work. Previous studies about identifying mainly from single networks, do not consider that users may participate different Here we identify feature named Ck-value combines structural...
Rumor spreading on online social media is presenting a significant threat to society of post-truth epoch. Extensive efforts have been devoted rumor identification and debunking, assuming that specific propagation single event network neglecting possible interdependence between different cascades. Here we study the collective multiple rumors, surprisingly find users repeatedly participate in Though these repetitive demonstrate minor difference at level network, they are found form...
Fake news has permeated into people's daily life especially with the help of popularity online social networks. Hence containment fake propagation becomes a vital issue for modern society. While previous research mainly focused on game theory and information diffusion models single network, little attention was paid to realistic networks as well multi-networks. Our finding concentrates tests effect re-posting silence volume control quantitatively. Furthermore, multi-network, these two...
In recent years, social networks such as Twitter and Weibo have developed rapidly. At the same time, false harmful information has spread rapidly in online like a plague caused great negative impact on people who don't know truth. We found that fake news turns to different structural features of their propagation compared with real news. With careful analysis, we reveal is by self-loop (one user reposts its own re-posting) some degree. This abnormal pattern could be feature identification...
Entertainment news caters to people's desires for leisure and gossip. Recently, with the Internet popularization, online social network has become a convenient platform netizens receive spread entertainment news. Previous study efforts of focused on analyzing psychological background economic significance However, little attention was paid realistic propagation structure features news, which reflect essential mechanisms. This research analyzes different types in network, other are compared...
The Internet of Things (IoT) leads the era interconnection, where numerous sensors and devices are being introduced interconnected. To support such an amount data traffic, wireless communication technologies have to overcome available spectrum shortage complex fading channels. transform domain system (TDCS) is a cognitive anti-interference with low probability detection dynamic sensing accessing. However, non-continuous asymmetric brings new challenges traditional TDCS block-type pilot,...
Fake news and real are different in many aspects. Many scholars analyze from the perspective of text, users so on. This paper compares analyzes these two types information aspect network structure: community detection. We found that number participating networks is larger fake news, participation multi-network stronger, size more average. abnormal spread pattern could be a feature identification motivate future studies this direction.
Unknown time-varying interference is a common and practical problem for communication system. An end-to-end learning system with transform domain suppression proposed in this paper to suppress the real-time autoencoder(AE) neural networks. The basic idea dynamical shape waveform at both AE transmitter receiver avoid interfered spectral regions. simulation shows that method can save 2dB Eb/N0 bit error ratio 10 <sup xmlns:mml="http://www.w3.org/1998/Math/MathML"...
