We introduce a novel logic-based system for reasoning over data streams, which relies on a framework enabling a tight, fine-tuned interaction between Apache Flink and the I^2-DLV system. The architecture allows to take advantage from both the powerful distributed stream processing capabilities of Flink and the incremental reasoning capabilities of I^2-DLV based on overgrounding techniques. Besides the system architecture, we illustrate the supported input language and its modeling capabilities, and discuss the results of an experimental activity aimed at assessing the viability of the approach. This paper is under consideration in Theory and Practice of Logic Programming (TPLP).
DLV是一个高效的逻辑编程和非单调推理(LPNMR)系统,具有先进的知识表示机制和经典关系数据库系统的接口。它的核心语言是具有完整性约束的答案集语义(Answer Set Semantics)下的析取数据库(无函数析取逻辑编程),包括默认和强(或显式)否定以及查询。还支持算术运算和各种内置谓词。此外,DLV有几个前端,即勇敢和谨慎的推理,溯因诊断,基于一致性的诊断,SQL 3的一个子集,使用动作语言进行规划,以及使用继承进行逻辑编程。

魔术集是一种数据到数据的重写技术,用于优化查询应答。重写的程序集中在输入程序的稳定模型的一部分,这足以回答给定的查询。然而,重写可能会引入新的递归定义,甚至可能涉及否定和聚合,并可能减慢程序评估。本文通过防止在重写程序中创建(新的)递归定义来增强魔集技术。结果表明,新版本的幻集对于具有分层否定和聚合的Datastron程序是封闭的,这对于获得重写程序的稳定模型的有效计算是非常方便的.此外,重写的程序被进一步优化,通过消除所包含的规则和有效处理的情况下,绑定传播丢失。这项研究是由挑战刺激的利用Datasheet/ \textsc{dlv}高效推理的大型本体。因此,所有提出的技术已在\textsc{dlv}系统中实现,并进行本体推理测试,确认其有效性。《逻辑程序设计理论与实践》(Theory and Practice of Logic Programming)

本文考虑了大量(可能是分布式的)数据的推理问题。目前,现有的建议显示出一些局限性:{ \em(i)}由于推理通常在主存中进行的事实,可以同时处理的数据的量是有限的; { \em(ii)}与外部的交互(和独立的)DBMS不是微不足道的,在某些情况下,根本不允许;{ \em(iii)}当前实现的效率对于它们在涉及大量数据的复杂推理任务中的利用仍然是不够的。本文提供了在这种情况下的贡献,它提出了一个新的系统,称为DLV $^{DB}$,旨在解决这些问题。此外,本文报告了一个彻底的实验分析的结果,我们已经进行了比较我们的系统与几个国家的最先进的系统(包括逻辑和数据库)的一些经典的演绎问题;其他测试系统是:LDL++,XSB,Smodels和三个顶级的商业DBMS。DLV $^{DB}$在递归查询上的性能甚至明显优于商业数据库系统。逻辑程序设计理论与实践(Theory and Practice of Logic Programming,TPLP)
