Collapse Button Quick Abstract
With the continuous progress and prosperity of mobile Internet science and technology, relying on it and the operation of Internet finance is also natural, and with its advantages of high transparency, good cooperation, intermediate costs and low cost, quickly occupied China’s financial market. Based on the measurement and analysis of the risk value of Internet finance and commercial banks, this paper studies the risk spillover effect of Internet finance on commercial banks from the macro and micro levels. Based on the principle of minimum AIC, BIC and maximum likelihood, this paper selects the best ArMA-GARCH model for the selected 2 groups of index series and 13 groups of return series, and calculates their risk value and risk spillover value on the basis of fitting (Wang 2021). In the aspect of risk measurement, the value of risk is quantized by calculating the value of risk (Va R), and in the aspect of risk spillover, the risk spillover effect is comprehensively analyzed by calculating the conditional value of risk (Co Va R), its derived index risk spillover value (△Co Va R) and relative risk spillover degree (%Co Va R). The empirical results show that the impact of Internet financial risks makes commercial banks suffer from positive risk spillover, but there is no consistency between macro and micro in the direction of risk spillover (Liu ). On the macro level, the empirical results show that Internet finance has positive risk spillover to commercial banks, but on the micro level, Yu ’ebao has positive and negative risk spillover to 12 commercial banks, and the spillover directions of different commercial banks are not consistent. In terms of overflow intensity, there is no uniform rule for different types of commercial banks.

Collapse Button Quick Abstract
With the prelude of the "people war" in major cities, various settlement policies have attracted numerous talents with higher education to settle in cities and become the population with the city’s household registration, which we can call household migrants. At present, most of the studies on migrants in China focus on the mobile population, and less on this part of people who are screened and left behind by the city as elites. Housing has a certain significance for immigrants, and can be said to be one of the more important issues in the process of urban integration, housing not only solves the major problem of living, more importantly, it contains the sentiment of home. Therefore, owning a set of their own house has become the goal of many immigrants to fight for, and household immigrants, as a member of the immigrant army, are no exception. Household immigrants, as elites screened out by the city, have an advantage in the labor market and an advantage in income, does this mean that they will have a smoother integration process in the city? An analysis of microdata from the General Social Survey verifies that even for household migrants, they may not have an advantage in acquiring housing because urban housing prices have continued to rise over the years and it is increasingly difficult for urban latecomers to obtain housing, coupled with the intergenerational inheritance nature of housing. In other words, for household migrants, there is a situation of housing exclusion in the process of urban integration.

Collapse Button Quick Abstract
We explain a new strategy to model a set of java classes and to abstract a model from them that can be use to study the impact that defects affecting specific classes can have on the whole system. We use the models of the software implementation as an abstraction of the software that can be used for experimentation We used simulation and verification in SPIN but the idea can be applied to implementations in other languages than java and the analysis of defects impact can be done with other verification tools as well.

Collapse Button Quick Abstract
We present an enhanced method for user feedback in an autonomous learning system that includes a spoken dialogue system to manage the interactions between the users and the system. By means of a rule-based natural language understanding module and a state-based dialogue manager we allow the users to update the preferences learnt by the system from the data obtained from different sensors. The design of the dialogue together with the storage of context information (the previous dialogue turns and the current state of the dialogue) ensures highly natural interactions, reducing the number of dialogue turns and making it possible to use complex linguistic constructions instead of isolated commands.

Collapse Button Quick Abstract
Software agents have been designed and implemented to function within limited context-aware capabilities. For an agent to function correctly and efficiently it should contain sufficient knowledge and reasoning resources enabling them to process large quantities of implicit information conveyed through an explicit description. Presented in this position paper is an introduction of the 6Ws agent-based architecture which encompasses key reasoning capabilities which are not adequately supported by existing BDI frameworks but have been recognized as highly relevant for the development of Ambient Intelligent systems.

Collapse Button Quick Abstract
Significant work has been done in the areas of Pervcomp/Ubicomp/Smart Environments with advances on making proactive systems, but those advances have not made these type of systems accurately proactive. On the other hand a great deal is needed to make systems more sensible/sensitive and trustable (both in terms of reliability and privacy). We put forward the thesis that a more integral and social-aware sort of intelligence is needed to effectively interact, decide and act on behalf of people’s interest and that a way to test how effective systems are achieving these desirable behaviour is needed as a consequence. We support our thesis by providing examples on how to measure effectiveness in variety of different environments.

Verification of Smart Homes Specifications which are based on ECA Rules

Author: Juan C. Augusto

Affiliation: School of Computing and Mathematics, University of Ulster at Jordanstown, United Kingdom

Digital Object Identifier: 10.5220/0002574701180120

Proceedings of MSVVEIS 2005/ICEIS, ISBN: 972-8865-22-8

Collapse Button Quick Abstract
Smart homes implementations are usually based on Active Databases (ADBs). A core concept of ADBs is the concept of Event-Condition-Action (ECA) rules allowing the system to react to specific events occurring in contexts of interest and advising on an the actions that should be taken in those situations. Although research in ADBs has been conducted for quite a few years, still no standard verification framework has emerged yet from the area. In this paper we consider some options to verify specifications of Smart Homes based on ADB-related concepts.

DURATIVE EVENTS IN ACTIVE DATABASES

Collapse Button Quick Abstract
Active databases are DBMS which are able to detect certain events in the environment and trigger actions in consequence. Event detection has been subject of much research, and a number of different event specification languages is extant. However, this is far from being a trivial or accomplished task. Most of these languages handle just instantaneous events, but it has been noticed that a number of situations arise where it would be interesting or even necessary to handle durative events. We elaborate on a given specification language which combines instantaneous and durative events, revealing some issues which must be taken into account when the semantics of event composition is defined.

Collapse Button Quick Abstract
Because of their complexity, business transactions are prone to failure in many ways. This paper reports on our experience using a fault-based testing approach. The approach overcomes the limitations of specification-based approaches that derive from the intrinsic incompleteness of the specification, and from the focus of specifications on correct behaviors, rather than potential faults, and hence provides a complementary technique during the testing phase.

Collapse Button Quick Abstract
Query rewriting using views is an important issue in data integration. Several algorithms have been proposed, such as the bucket algorithm, the inverse rules algorithm, the SVB algorithm, and the MiniCon algorithm. These algorithms can be divided into two categories. The algorithms of the first category are based on use of buckets while the ones of the second category are based on use of inverse rules. The bucket-based algorithms have not considered the effects of integrity constraints, such as domain semantics, functional and inclusion dependencies. As a result, they might miss query rewritings or generate redundant query rewritings in the presence of these constraints. A bucket-based algorithm consists of two steps. The first step is called view selection that selects views relevant to a given query and puts the views into the corresponding buckets. The second step is to generate all the possible query rewritings by combining a view from each bucket. In this paper, we consider an improvement of view selection in the bucket-based algorithms using domain semantics. We use the resolution method to generate a pseudo residue for each view given a set of domain semantics. Given a query, the pseudo residue of each view is compared with it and any conflict that exists can be found. As a result, irrelevant views can be removed even before a bucket-based algorithm is used.
