We define variants of the state/event based logic UCTL* along with two example applications to demonstrate this approach, and then look at a distributed, rich Internet application, proving properties about the information it stores and disseminates. Our approach enables us to justify proofs about abstract properties that are preserved in the face of concurrent, networked inputs by proofs about concrete properties in an Internet setting. We conclude that our approach makes it possible to reason about the programs and protocols that comprise the Internet's application layer with reliability and generality.","PeriodicalId":233765,"journal":{"name":"International Workshop on Automated Specification and Verification of Web Sites","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133288207","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We provide an introduction to the Web of Linked Data from the perspective of a Web developer that would like to build an application using Linked Data. We identify a weakness in the development stack as being a lack of domain specific scripting languages for designing background processes that consume Linked Data. To address this weakness, we design a scripting language with a simple but appropriate type system. In our proposed architecture some data is consumed from sources outside of the control of the system and some data is held locally. Stronger type assumptions can be made about the local data than external data, hence our type system mixes static and dynamic typing. Throughout, we relate our work to the W3C recommendations that drive Linked Data, so our syntax is accessible to Web developers.","PeriodicalId":233765,"journal":{"name":"International Workshop on Automated Specification and Verification of Web Sites","volume":"72 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-07-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127669778","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this paper we study how to adapt the XPath query language to GML documents. With this aim, we have defined a semantic based XPath language which is not based on the (tree-based) syntactic structure of GML documents, instead it is based on the “semantic structure” of GML documents. In other words, the proposed XPath language is based on the GML schema. We have developed a system called UALGIS, in order to implement the approach. Such system stores GML documents by means of the PostGIS RDBMS. In order to execute semantic-based XPath queries we have defined a translation of the queries into SQL. Such translation takes into account the GML schema. Finally, the system allows to visualize the result. With this aim, the result of a query is exported to the Keyhole Markup Language (KML) format.","PeriodicalId":233765,"journal":{"name":"International Workshop on Automated Specification and Verification of Web Sites","volume":"52 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-07-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126507859","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Freitag","doi":"10.29007/dclv","DOIUrl":"https://doi.org/10.29007/dclv","url":null,"abstract":"Digital text, in particular hypertext, can be represented as a temporal structure based on the concept of narrative paths. Using computation tree logic (CTL) as a formal basis, consistency constraints about the document can then be expressed as temporal properties. These in turn can be verified against the document model by model checking. Unfortunately, the average user can not be assumed to be familiar with temporal logics. Therefore, as an approach to fill the gap between formality and usability, we present a novel user-friendly highlevel approach to the specification of temporal properties supporting an incremental construction of commonly used consistency criteria for web documents.","PeriodicalId":233765,"journal":{"name":"International Workshop on Automated Specification and Verification of Web Sites","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-07-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126835595","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Answer Set Programming in a Nutshell 简而言之，答案集编程

{"title":"Answer Set Programming in a Nutshell","authors":"Thomas Eiter","doi":"10.29007/tmt3","DOIUrl":"https://doi.org/10.29007/tmt3","url":null,"abstract":"Answer Set Programming (ASP) has emerged in the recent years as a powerful paradigm for declarative problem solving, which has its roots in knowledge representation and nonmonotonic logic programming. Similar to SAT solving, the basic idea is to encode solutions to a problem in the models of a non-monotonic logic program, which can be computed by reasoning engines off the shelf. ASP is particularly well-suited for modeling and solving problems which involve common sense reasoning or transitive closure, and has been fruitfully applied to a growing range of applications. Among the latter are also problems in testing and verfication, for which efficient core fragments of ASP that embrace Datalog haven been exploited. This talk gives a brief introduction to ASP, covering the basic concepts, some of its properties and features, and solvers. It further addresses some applications in the context of verification and recent developments in ASP, which bring evaluation closer to other formalisms and logics. L. Kovacs, T.

In this framework, a hyperdocument is dened via its abstract syntax, which is a variablefree term of a suitable constructor-based signature. Both the representation in a markup language and the graphical presentation on the screen as well as further representations are elements of particular algebraic interpretations of the same signature. This technique allows the application of well-known methods from the eld of compiler construction to the development of hyperdocument systems. Ideas for its implementation in the functional language Haskell are roughly drafted. It is shown how XML-based markup languages with schemas and stylesheets can be dened in terms of this framework and how this framework can be extended so that it can deal with partially specied documents, called semi documents. These semi documents can be automatically adapted to the users’ needs, which e.g. is helpful to ensure accessibility.","PeriodicalId":233765,"journal":{"name":"International Workshop on Automated Specification and Verification of Web Sites","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-07-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130614829","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Our work aims at fully automatic testing of web services: ideally the user only specifies properties that the web service is expected to satisfy, in the form of input-output relations, and the system handles all the rest. In this paper we present in detail the component which lies at the heart of this system: how the WSDL specification of a web service is used to automatically create test case generators that can be fed to PropEr, a property-based testing tool, to create structurally valid random test cases for its operations and check its responses. Although the process is fully automatic, our tool optionally allows the user to easily modify its output to either add semantic information to the generators or write properties that test for more involved functionality of the web services.","PeriodicalId":233765,"journal":{"name":"International Workshop on Automated Specification and Verification of Web Sites","volume":"30 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-10-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127985460","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
