Node classification is a substantial problem in graph-based fraud detection. Many existing works adopt Graph Neural Networks (GNNs) to enhance detectors. While promising, currently most GNN-based detectors fail generalize the low homophily setting. Besides, label utilization has been proved be significant factor for node problem. But we find they are less effective detection tasks due graphs. In this work, propose GAGA, novel Group AGgregation enhanced TrAnsformer, tackle above challenges....

Recently, graph query is widely adopted for querying knowledge graphs. Given a G <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">Q</sub> , the finds subgraphs in that exactly or approximately match . We face two challenges on query: (1) structural gap between and predefined schema causes mismatch with graph, (2) users cannot view answers until terminates, leading to longer system response time (SRT). In this paper, we propose semantic-guided...

Iodine assays hold paramount significance in clinical diagnostics, thyroid hormone synthesis, and pharmaceutical advancements. DNA-based optical fiber biosensors have emerged as a pivotal platform for ion detection, leveraging their biocompatibility, specificity, remarkable sensitivity. Due to the unique bonding characteristics of its bases, DNA probes can only form specific coordination structures with cations, posing challenges anion detection. Based on principle ion-competition binding...

Analysis of range queries on spatial (multidimensional) data is both important and challenging. Most previous analysis attempts have made certain simplifying assumptions about the sets and/or to keep tractable. As a result, they may no be universally applicable. This paper proposes set five techniques estimate selectivity number index nodes accessed in serving query. The underlying philosophy behind these maintain an auxiliary structure called density file, whose creation one-time cost,...

Billions of lightweight Internet Things (IoT) devices have been deployed for various applications nowadays. Most them first collect interested data and then process in some degree according to application requirements. Transparent computing (TC) is a promising technique that makes such suitable even large-size applications. The advantage TC separate code storage from its execution, allowing IoT load blocks nearby server on demand. Distinct existing work, this paper allows the offload tasks...

Recent developments in networking have spurred the emergence of time-sensitive applications such as Web search, social networks, and Industrial Internet. TCP, core protocol, implements reliable packet delivery for these applications. However, TCP isn't specifically optimized timely delivery, so it has poor performance scenarios. To counter this, network research community worked extensively on standards reducing TCP's latency. Explicit Congestion Notification (ECN) is an extension to TCP/IP...

A knowledge graph (KG) manages large-scale and real-world facts as a big in schema-flexible manner. Aggregate query is fundamental over KGs, e.g., "what the average price of cars produced Germany?". Despite its importance, answering aggregate queries on KGs has received little attention literature. can be supported based factoid queries, "find all Germany", by applying an additional operation queries' answers. However, this straightforward method challenging because both accuracy efficiency...

Fraud detection on multi-relation graphs aims to identify fraudsters in graphs. Graph Neural Network (GNN) models leverage graph structures pass messages from neighbors the target nodes, thereby enriching representations of those nodes. However, feature and structural inconsistency graph, owing fraudsters' camouflage behaviors, diminish suspiciousness fraud nodes which hinders effectiveness GNN-based models. In this work, we propose DiG-In-GNN, Discriminative Feature Guided GNN against...
