Classical negation in logic programs and disjunctive databases

by Michael Gelfond, Vladimir Lifschitz - New Generation Computing , 1991
"... An important limitation of traditional logic programming as a knowledge representation tool, in comparison with classical logic, is that logic programming does not allow us to deal directly with incomplete information. In order to overcome this limitation, we extend the class of general logic progra ..."

programs by including classical negation, in addition to negation-as-failure. The semantics of such extended programs is based on the method of stable models. The concept of a disjunctive database can be extended in a similar way. We show that some facts of commonsense knowledge can be represented by logic

The Universal Protein Resource (UniProt): an expanding universe of protein information

by Cathy H. Wu, Rolf Apweiler, Amos Bairoch, Darren A. Natale, Winona C. Barker, Brigitte Boeckmann, Serenella Ferro, Elisabeth Gasteiger, Hongzhan Huang, Rodrigo Lopez, Michele Magrane, Maria J. Martin, Raja Mazumder, Nicole Redaschi, Baris Suzek - Nucleic Acids Res , 2006

VisualNet: Commonsense Knowledgebase for Video and Image Indexing and Retrieval Application

by Amjad A. Altadmri, Amr A. Ahmed
"... Abstract—The rapidly increasing amount of video collections, available on the web or via broadcasting, motivated research towards building intelligent tools for searching, rating, indexing and retrieval purposes. Establishing a semantic representation of visual data, mainly in textual form, is one o ..."

of the important tasks. The time needed for building and maintaining Ontologies and knowledge, especially for wide domain, and the efforts for integrating several approaches emphasize the need for unified generic commonsense knowledgebase for visual applications. In this paper, we propose a novel commonsense

Corpus-based and knowledge-based measures of text semantic similarity

by Rada Mihalcea, Courtney Corley, Carlo Strapparava - IN IPROCEEDINGS OF THE 21ST NATIONAL CONFERENCE ON ARTIFICIAL INTELLIGENCE - VOLUME 1 , 2006
"... This paper presents a method for measuring the semantic similarity of texts, using corpus-based and knowledge-based measures of similarity. Previous work on this problem has focused mainly on either large documents (e.g. text classification, information retrieval) or individual words (e.g. synonymy ..."

Knowledge representation and reasoning

by Ronald J. Brachman, Hector J. Levesque , 2003
"... Knowledge Representation is the area of Artificial Intelligence (AI) concerned with how knowledge can be represented symbolically and manipulated in an automated way by reasoning programs. It is at the very core of a radical idea about how to understand intelligence: instead of trying to understand ..."

or build brains from the bottom up, we try to understand or build intelligent behavior from the top down. In particular, we ask what an agent would need to know in order to behave intelligently, and what computational mechanisms could allow this knowledge to be made available to the agent as required

Collecting Commonsense Experiences

by Push Singh, Barbara Barry , 2003
"... Humans naturally share knowledge by telling stories. This is a form of knowledge exchange we engage in right from early childhood, and over time we learn to recall, order and organize our experiences as stories [1]. In this paper we describe the Open Mind Experience(OMEX) system, a web-based knowled ..."

Commonsense reasoning by distance semantics

by Ofer Arieli - In Proc. TARK’07 , 2007
"... We introduce a uniform distance seman-tics for different paradigms that require nonmonotonic and paraconsistent reason-ing, among which are mediators of inde-pendent data-sources, integrators of pri-oritized knowledge-bases, operators for iterated belief revision, and analytic tools of decision supp ..."

This domainindependent knowledge is provided at different levels of semantics by a fully automated engine
