We quantitatively describe the main events that led to Terra project's failure in May 2022. first review, a systematic way, news from heterogeneous social media sources; we discuss fragility of project and its vicious dependence on Anchor protocol. hence identify crash's trigger events, analysing hourly transaction data for Bitcoin, Luna, TerraUSD. Finally, using state-of-the-art techniques net...

The article introduces the basic ideas and investigates the probabilistic version of rough set theory. It relies on both classification knowledge and probabilistic knowledge in analysis of rules and attributes. Rough approximation evaluative measures and one-way and two-way inter-set dependency measures are proposed and adopted to probabilistic rule evaluation. A new probabilistic dependency me...

Understanding chemical-disease relations (CDR) from biomedical literature is important for biomedical research and chemical discovery. This paper uses a k-max pooling convolutional neural network (CNN) to exploit word sequences and dependency structures for CDR extraction. Furthermore, an effective weighted context method is proposed to capture semantic information of word sequences. Our system...

Constructing scalable high-performance applications on commodity hardware running the Unix operating system is a problem that must be addressed in several application domains. We relate our experience in achieving transaction scaleup on Unix for a high-performance OLTP system intended for Service Control Points (SCPs) in a telephone switching network. We view the requirements of SCPs as prototy...

Natural language processing (NLP) annotation projects employ guidelines to maximize inter-annotator agreement (IAA), and models are estimated assuming that there is one single ground truth. However, not all disagreement is noise, and in fact some of it may contain valuable linguistic information. We integrate such information in the training of a cost-sensitive dependency parser. We introduce f...

This paper presents a method for pricing multi-variate options using non-recombining trees. The trees are generated using a moment-based approach, so no distributional assumptions are needed. To apply the method, the user has to know the properties (moments and correlations) of the risk-neutral distributions of returns of all the assets the options depend on. European options are priced on sing...

Purpose – Business process outsourcing (BPO) has become so prevalent that a new term, the extended enterprise, has arisen to describe this approach to structuring an organization. The purpose of this article is to integrate the information systems and the interfirm governance literatures to develop a framework for the role of trust in the governance of extended enterprises. Design/methodology/a...

This paper develops a research model on the roles of transaction cost reduction and explicit coordination in mediating the impacts of inter-organizational information systems (IOS) use on buyer benefits. Empirical tests find that both the transaction costs reduction and explicit coordination are significantly impacted by IOS use. However, it is found that the impacts of IOS use on buyer benefit...

This project describes the composition and goals of the Multisession Audio Research Project (MARP) corpus and some initial experimental findings. The MARP corpus is a three year longitudinal collect of 21 sessions and more than 60 participants. This study was undertaken to test the impact of various factors on speaker recognition, such as inter-session variability, intonation, aging, whispering...
