One is to show that the dynamic knowledge representation paradigm introduced in [ALP+00] and the associated language LUPS, defined in [APPP99], constitute natural, powerful and expressive tools for representing dynamically changing knowledge. We do so by demonstrating the applicability of the dynamic knowledge representation paradigm and the language LUPS to several broad knowledge representation domains, for each of which we provide an illustrative example. Our second objective is to extend our approach to allow proper handling of conflicting updates. So far, our research on knowledge updates was restricted to a two-valued semantics, which, in the presence of conflicting updates, leads to an inconsistent update, even though the updated knowledge base does not necessarily contain any truly contradictory information. By extending our approach to the three-valued semantics we gain the added expressiveness allowing us to express undefined or noncommittal updates.DI - Departamento de InformáticaCENTRIA – Centro de Inteligência ArtificialRUNAlferes, José Júlio AlvesPereira, L.M.Przymusinska, HPrzymusinski, Teodor C.Quaresma, Paulo2019-06-12T22:14:24Z2000-01-012000-01-01T00:00:00Zconference objectinfo:eu-repo/semantics/publishedVersion10application/pdfhttp://hdl.handle.net/10362/72468eng3-540-41044-9PURE: 104474http://www.scopus.com/record/display.uri?eid=2-s2.0-84947921593&origin=resultslist&sort=plf-f&src=s&st1https://doi.org/10.1007/3-540-45331-8_1info:eu-repo/semantics/openAccessreponame:Repositório Científico de Acesso Aberto de Portugal (Repositórios Cientìficos)instname:Agência para a Sociedade do Conhecimento (UMIC) - FCT - Sociedade da Informaçãoinstacron:RCAAP2024-05-22T17:39:56Zoai:run.unl.pt:10362/72468Portal AgregadorONGhttps://www.rcaap.pt/oai/openairemluisa.alvim@gmail.comopendoar:71602024-05-22T17:39:56Repositório Científico de Acesso Aberto de Portugal (Repositórios Cientìficos) - Agência para a Sociedade do Conhecimento (UMIC) - FCT - Sociedade da Informaçãofalse
