Since mobile Internet services are rapidly proliferating, finding and using appropriate services require profound service descriptions. As a consequence, for average mobile users it is nowadays virtually impossible to find the most appropriate service among the many offered. To overcome these difficulties, task navigation systems have been proposed to guide users towards best-fitting services. Our goal is to improve the user experience of such task navigation systems making them context-aware (i.e. to optimize service navigation by taking the user's situation into account). We propose the integration of a situational reasoning engine that applies classification-based inference to qualitative context elements, gathered from multiple sources and represented using ontologies. The extended task navigator enables the delivery of situation-aware recommendations in a proactive way. Initial experiments with the extended system indicate a considerable improvement of the navigator's usability.<\/jats:p>","DOI":"10.1017\/s0269888907001300","type":"journal-article","created":{"date-parts":[[2008,3,18]],"date-time":"2008-03-18T10:08:45Z","timestamp":1205834925000},"page":"7-19","source":"Crossref","is-referenced-by-count":26,"title":["Situational reasoning for task-oriented mobile service recommendation"],"prefix":"10.48130","volume":"23","author":[{"given":"MARKO","family":"LUTHER","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"YUSUKE","family":"FUKAZAWA","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"MATTHIAS","family":"WAGNER","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"SHOJI","family":"KURAKAKE","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"27968","published-online":{"date-parts":[[2008,3,1]]},"reference":[{"key":"S0269888907001300_ref043","doi-asserted-by":"publisher","DOI":"10.1109\/MPRV.2002.1037720"},{"volume-title":"Proceedings of the 2nd International Workshop on Scalable Semantic Web Knowledge Base Systems (SSWS\u201906)","year":"2006","author":"Weith\u00f6ner","key":"S0269888907001300_ref042"},{"volume-title":"Proceedings of the PerCom Workshop on Context Modeling and Reasoning (CoMoRea\u201904)","year":"2004","author":"Wang","key":"S0269888907001300_ref041"},{"volume-title":"Proceedings of the 19th International Conference on Artificial Intelligence (IJCAI\u201905),","year":"2005","author":"Tsarkov","key":"S0269888907001300_ref039"},{"volume-title":"Proceedings of the 10th International Conference on the Principles of Knowledge Representation and Reasoning (KR\u201906)","year":"2006","author":"Sirin","key":"S0269888907001300_ref037"},{"volume-title":"WWW\u201906 Workshop on Reasoning on the Web (RoW\u201906)","year":"2006","author":"Parsia","key":"S0269888907001300_ref036"},{"volume-title":"Proceedings of the 1st Workshop on Context Awareness for Proactive Systems (CAPS\u201905),","year":"2005","author":"Mrohs","key":"S0269888907001300_ref032"},{"key":"S0269888907001300_ref031","doi-asserted-by":"publisher","DOI":"10.1016\/j.websem.2005.05.001"},{"key":"S0269888907001300_ref030","doi-asserted-by":"publisher","DOI":"10.1207\/S15327051HCI16234_01"},{"key":"S0269888907001300_ref029","unstructured":"McGuinness D. and van Harmelen F. 2004 OWL Web Ontology Language overview.
