This paper presents the concept of unmanned vehicle situation awareness and provides a discussion of how unmanned vehicle situation awareness can be defined based upon human situation awareness. A broadly accepted human situation awareness definition is directly applied to the notion of unmanned vehicle situation awareness. The paper also discusses unique unmanned vehicle aspects that will infl...

This paper explores the relationship between Situation Awareness, Common Operating Pictures and Data Fusion to expose the need for Situation and Impact Assessments. A framework for Situation Assessments is then proposed and illustrated through reference to footage from the movie, “The Hunt for Red October”

1 SUMMARY  There were 20 confirmed cases of Ebola virus disease (EVD) reported in the week to 28 June, the same as the previous week. Weekly case incidence has been between 20 and 27 cases for 5 consecutive weeks. In Guinea, 12 cases were reported from 3 prefectures: Boke, Conakry, and Forecariah. All 3 prefectures reported cases the previous week. In Sierra Leone, 8 cases were reported from t...

1 SUMMARY  In recent weeks, the decline in case incidence and the contraction of the geographic area affected by Ebola virus disease (EVD) transmission that was apparent throughout April and early May has stalled. In total, 31 confirmed cases of EVD were reported in the week ending 7 June: 16 cases in Guinea and 15 in Sierra Leone. This is the second consecutive weekly increase in case inciden...

Towards Autonomous Situation Awareness

The notions of ‘‘situation’’ and ‘‘situation awareness’’ have been formulated by many authors in various contexts. In this paper, we present a formalization of situations that is compatible with the interpretation of situation awareness in terms of human awareness as well as the situation theory of Barwise and Devlin. The purpose of this paper is to capture the situation theory of Barwise in te...

Context-aware computing applications often perform an assessment of similarity between the user’s current situation and the predefined or learned situations in order to trigger appropriate adaptation rules. Because future situations are often not exactly matching with past ones (e.g., time continuously changes), the assessment of similarity between situations is not a straightforward task. This...

The research landscape examining situation models in discourse has been transformed considerably in the last 20 years. Van Dijk and Kintsch (1983) originally included the concept of a situation model to address issues that were problematic for earlier versions of their theory (Kintsch & van Dijk, 1978). Specifically, van Dijk and Kintsch (1983) argued that situation models were necessary to exp...

This paper presents an annotation scheme for a new semantic annotation task with relevance for analysis and computation at both the clause level and the discourse level. More specifically, we label the finite clauses of texts with the type of situation entity (e.g., eventualities, statements about kinds, or statements of belief) they introduce to the discourse, following and extending work by S...

1 SUMMARY  A total of 82 new confirmed cases of Ebola virus disease (EVD) were reported in the week to 29 March, a slight increase compared with 79 cases the previous week. Case incidence in Guinea increased to 57, compared with 45 the previous week. This offset a fourth consecutive weekly fall in case incidence in Sierra Leone, which reported 25 confirmed cases. Liberia reported no confirmed ...
