We propose twenty different classes of shielded base contractions and obtain axiomatic characterizations for each one of them. Additionally we thoroughly investigate the interrelations (in the sense of inclusion) among all those classes.<\/jats:p>","DOI":"10.24963\/ijcai.2019\/889","type":"proceedings-article","created":{"date-parts":[[2019,7,28]],"date-time":"2019-07-28T03:46:05Z","timestamp":1564285565000},"page":"6367-6371","source":"Crossref","is-referenced-by-count":0,"title":["Shielded Base Contraction (Extended Abstract)"],"prefix":"10.24963","author":[{"given":"Marco","family":"Garapa","sequence":"first","affiliation":[{"name":"Faculdade de Ci\u00eancias Exatas e da Engenharia, Universidade da Madeira"},{"name":"CIMA - Centro de Investiga\u00e7\u00e3o em Matem\u00e1tica e Aplica\u00e7\u00f5es"}]},{"given":"Eduardo","family":"Ferm\u00e9","sequence":"additional","affiliation":[{"name":"Faculdade de Ci\u00eancias Exatas e da Engenharia, Universidade da Madeira"},{"name":"NOVA Laboratory for Computer Science and Informatics (NOVA LINCS)"}]},{"given":"Maur\u00edcio D.
