Argument-based mixed recommenders and their application to movie suggestion
Cristian E. Briguez,Maximiliano Celmo David Budán,Cristhian A. D. Deagustini,Ana Gabriela Maguitman,Marcela Capobianco,Guillermo Ricardo Simari +5 more
TL;DR: A novel perspective on movie recommendation that combines a basic quantitative method with a qualitative approach, resulting in a family of mixed character recommender systems, and is evaluated obtaining very positive results.

Assumption-free semantics for ordered logic programs: on the relationship between well-founded and stable partial models
Els Laenens,Dirk Vermeir +1 more
TL;DR: The central issue of this paper is the definition of a new unifying semantics for ordered logic programs, called assumption-free semantics, capable of capturing different interesting semantics such as the well-founded and stable (partial model) semantics.

Relational databases as a massive information source for defeasible argumentation
Cristhian A. D. Deagustini,Santiago E. Fulladoza Dalibón,Sebastián Gottifredi,Marcelo Alejandro Falappa,Carlos Iván Chesñevar,Guillermo Ricardo Simari +5 more
TL;DR: This paper presents a novel approach to compute arguments from premises obtained from relational databases, identifying several relevant aspects and contends that this proposal is significant for developing new architectures for knowledge-based applications, such as Decision Support Systems and Recommender Systems, using argumentation as the underlying inference model.

Well-founded semantics and stratification for ordered logic programs
Nicola Leone,G. Rossi +1 more
TL;DR: An extension of traditional logic programming, called ordered logic (OL) programming, is presented to support classical negation as well as constructs from the object-oriented paradigm to cope with the notions of object, multiple inheritance and non-monotonic reasoning.

The basic query machine of the KIWIS system
TL;DR: The basic implementation principles as well as the integrated architecture of the Basic Query Machine (BQM) — the module of KIWIS in charge of implementing the bottom-up model of execution of a class of LOCO programs, are described.

Implementation techniques for main memory database systems
David J. DeWitt,Randy H. Katz,Frank Olken,Leonard D. Shapiro,Michael Stonebraker,Darien Wood +5 more
TL;DR: This paper considers the changes necessary to permit a relational database system to take advantage of large amounts of main memory, and evaluates AVL vs B+-tree access methods, hash-based query processing strategies vs sort-merge, and study recovery issues when most or all of the database fits in main memory.

A federated architecture for information management
Dennis Heimbigner,Dennis McLeod +1 more
TL;DR: An approach to the coordinated sharing and interchange of computerized information is described emphasizing partial, controlled sharing among autonomous databases.

User Interface Management Systems
TL;DR: In this paper, the authors proposed a DEVICE-DEVICE DEVC DEVICE DEVICE (Device-Device-Device Discrete Controller) for autonomous driving systems and demonstrated its performance.

The architecture of the EXODUS extensible DBMS
Michael J. Carey,David J. DeWitt,Daniel Frank,M. Muralikrishna,Goetz Graefe,Joel E. Richardson,Eugene J. Shekita +6 more
TL;DR: EXODUS as discussed by the authors is an extensible database system that will facilitate the fast development of high-performance, application-specific database systems, including a versatile storage manager and a type manager.
