Software verification is known to be a notoriously difficult application area for automated theorem provers. Consequently, this is the domain of interactive systems, such as KIV [Reif et al., 1997], HOL [Gordon and Melham, 1993], Isabelle [Nipkow and Paulson, 1992] and PVS [Owre et al., 1992]. The work described here aims to demonstrate that automated theorem provers (ATPs) can be successfully ...

The deployment of Next-Generation Networks (NGN) is a challenge that requires integrating heterogeneous services into a global system of All-IP telecommunications. These networks carry voice, data, and multimedia traffic over the Internet, providing users with the information they want in any format, amount, device, place or moment. Still, there are certain issues, such as the emerging security...

This is a proposal for a next generation of CHR called CHR2. It combines the best features of language extensions proposed in earlier work and offers a solution to their main drawbacks. We introduce several novel language features, designed to allow the flexible, high-level specification of readable, efficient programs. Moreover, CHR2 is backwards compatible, such that existing programs can mak...

Extractive summarization is the strategy of concatenating extracts taken from a corpus into a summary, while abstractive summarization involves paraphrasing the corpus using novel sentences. We define a novel measure of corpus controversiality of opinions contained in evaluative text, and report the results of a user study comparing extractive and NLG-based abstractive summarization at differen...

Effective theorem provers are essential for automatic verification and generation of programs. The conventional resolution strategies, albeit complete, are inefficient. On the other hand, special purpose methods, such as term rewriting systems for solving word problems, are relatively efficient but applicable to only limited classes of problems. In this paper, a simple canonical set of rewrite ...

Rule-based formalisms are ubiquitous in computer science. However, a difficulty that arises frequently when specifying or programming the rules is to determine which effects should be propagated by these rules. In this paper, we present a tool called ARM (Automatic Rule Miner) that generates rules for relations over finite domains. ARM offers a rich functionality to provide the user with the po...

Maintaining consistency between design and implementation is a fundamental issue in software evolution. Although existing tools and techniques provide support for correcting inconsistencies, they target generally-applicable design rules. Unfortunately, in addition to these common design rules, any software system has an abundance of custom design rules that are very specific to the system at ha...
