We show via a case study how this framework may be used as a basis for a \"possible-worlds\" style approach to epistemic and causal reasoning in a narrative setting. In this framework an agent may gain knowledge about both fluent values and action occurrences through sensing actions, lose knowledge via non-deterministic actions, and represent plans that include conditional actions whose conditions may be initially unknown.<\/jats:p>","DOI":"10.29007\/zswj","type":"proceedings-article","created":{"date-parts":[[2018,1,23]],"date-time":"2018-01-23T18:02:53Z","timestamp":1516730573000},"page":"75-61","source":"Crossref","is-referenced-by-count":3,"title":["An Epistemic Event Calculus for ASP-based Reasoning About Knowledge of the Past, Present and Future"],"prefix":"10.29007","volume":"26","author":[{"given":"Jiefei","family":"Ma","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Rob","family":"Miller","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Leora","family":"Morgenstern","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Theodore","family":"Patkos","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"11545","event":{"name":"LPAR-19. 19th International Conference on Logic for Programming, Artificial Intelligence and Reasoning"},"container-title":["EPiC Series in Computing"],"original-title":[],"deposited":{"date-parts":[[2018,1,23]],"date-time":"2018-01-23T18:04:55Z","timestamp":1516730695000},"score":1,"resource":{"primary":{"URL":"https:\/\/easychair.org\/publications\/paper\/sJ7"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[null]]},"references-count":0,"URL":"https:\/\/doi.org\/10.29007\/zswj","relation":{},"ISSN":["2398-7340"],"issn-type":[{"value":"2398-7340","type":"print"}],"subject":[]}}
