Languages, Ambiguity, and Verification

چکیده
This position paper is based on presentations given at the Grand Challenge workshops held at Gresham College in March 2004 and in Newcastle in July 2005. It reports some of our experience from building the SPARK language and its verification tools. We argue that the provision of an unambiguous semantics for a programming language is crucial if the verification framework is to be sound, deep and efficient. Secondly, we offer some reflections on the (mostly non-technical) barriers that we encounter in trying to deploy SPARK within organizations. Finally, we try to set some goals for future work. 1 Design goals for a program verification system A programming language and verification system that aim to meet this Grand Challenge might have the following design goals:

Semantic Priming Effect on Relative Clause Attachment Ambiguity Resolution in L2
This study examined whether processing ambiguous sentences containing relative clauses (RCs) following a complex determiner phrase (DP) by Persian-speaking learners of L2 English with different proficiency and working memory capacities (WMCs) is affected by semantic priming. The semantic relationship studied was one between the subject/verb of the main clause and one of the DPs in the complex D...
متن کاملTask Condition and EFL Learners’ Individual Differences: The Mediation of Tolerance of Ambiguity and Self-efficacy
Drawing on Robinson’s cognition hypothesis, the study attempted to examine how task conditions influence EFL learners’ oral performance and whether learners’ individual differences in terms of tolerance of ambiguity and self-efficacy mediate the effects of such conditions. To this end, 62 Iranian intermediate EFL learners from private language institutes in Tehran performed four dyadic decision...
متن کاملRelative Clause Ambiguity Resolution in L1 and L2: Are Processing Strategies Transferred?
This study aims at investigating whether Persian native speakers highly advanced in English as a second language (L2ers) can switch to optimal processing strategies in the languages they know and whether working memory capacity (WMC) plays a role in this respect. To this end, using a self-paced reading task, we examined the processing strategies 62 Persian speaking proficient L2ers used to read...
متن کاملWeb Service Choreography Verification Using Z Formal Specification
Web Service Choreography Description Language (WS-CDL) describes and orchestrates the services interactions among multiple participants. WS-CDL verification is essential since the interactions would lead to mismatches. Existing works verify the messages ordering, the flow of messages, and the expected results from collaborations. In this paper, we present a Z specification of WS-CDL. Besides ve...
متن کاملLR(K) Parser Construction Using Bottom-Up Formal Analysis
Design and construction of an error-free compiler is a difficult and challenging process. The main functionality of a compiler is to translate a source code to an executable machine code correctly and efficiently. In formal verification of software, semantics of a language has more meanings than the syntax. It means source program verification does not give guarantee the generated code is corre...
