The blockchain cross-chain is a significant technology for inter-chain interconnection and value transfer among different networks. Cross-chain overcomes the "information island" problem of closed network increasingly applied to multiple critical areas such as finance internet things (IoT). Blockchain can be divided into three main categories networks: public blockchains, private consortium blockchains. However, there are differences in block structures, consensus mechanisms, complex working...
With the rapid development of blockchain technology, its applications have been extended to various fields such as supply chains, internet things, and finance. However, different blockchains cannot directly interconnect due discrepancies in architecture, resulting data islands. Cross-chain technologies are services that provide interoperability for blockchains, enabling them exchange transfer assets. This paper summarizes analyzes cross-chain notary schemes, hash-locking, relays. We find may...
Blockchain technology has been widely used in digital currency, Internet of Things, and other important fields because its decentralization, nontampering, anonymity. The vigorous development blockchain cannot be separated from the security guarantee. However, there are various threats within that have shown past to cause huge financial losses. This paper aims at studying multi-level existing Ethereum blockchain, exploring protection schemes under multiple attack scenarios. There ten...
Usage-based insurance (UBI) provides reasonable vehicle premiums based on usage and driving behavior. In general, there are three major issues in realizing intelligent UBI systems. First, evaluation mechanisms not auditable to drivers. Insurers may thus deliberately adjust the premiums. Second, process of collecting data by insurers lead serious privacy breaches. Third, forging safer for reducing cause economic losses insurers. To address these challenges, this study, we propose CCUBI, a...
“Social sensors” refer to those who provide opinions through electronic communication channels such as social networks. There are two major issues in current models of sentiment analysis sensor First, most existing only analyzed the within text but did not analyze users, which led experimental results difficult explain. Second, few studies extract specific users. Only analyzing emotional tendencies or aspect-level emotions users brings difficulties opinion evolution public emergencies. To...
Abstract Aspect-based sentiment analysis is a subclass of tasks, focusing on judging the tendency entities or attributes, and has received extensive attention due to fine-grained results. The current research mostly summarizes from single point aspect extraction classification, lacks methods problems in aspect-based overall perspective. By using method literature investigation, an in-depth overview typical solutions given field three aspects: information extraction, classification joint...
Abstract Intelligent electric shovels are being developed for intelligent mining in open‐pit mines. Complex environment detection and target recognition based on image technology prerequisites achieving shovel operation. However, there is a large amount of sand–dust mines, which can lead to low visibility color shift the during data collection, resulting low‐quality images. The images collected environmental perception seriously affect scene segmentation capabilities shovels. Therefore,...
With the increasing development of social technology, image data on Internet shows an explosive growth. In a large number complex and different databases, how to make better use features achieve simple efficient real-time retrieval is new challenge we face. recent years, has begun develop towards multi-feature fusion specific application scenarios, but addition most text relies annotation information, uses tags or description semantics for retrieval. this way, information not mentioned in...
