This paper investigates automatic detection of different types of self-repairs in spontaneous speech under different social contexts, from casual conversations to government hearings. The work shows that a simple CRF-based model is effective for cross-domain training, which is important for contexts where annotated data is not available. The approach explicitly represents common types of disflu...

Within organisations, Information Systems are characterised by heterogeneity. The main management tools are different Relational and Object Oriented DataBase Management Systems. Therefore, variety, complexity and lack of integration make it difficult for casual users to query them. This paper presents WDBQS (Web DataBase Query System); a Web-interface for querying distant Relational and Object ...

In 2013, the World Health Organization (WHO) called for joint surveillance of population salt and iodine intakes using urinary analysis. 24-h urine collection is considered the gold standard for salt intake assessment, but there is an emerging consensus that casual urine sampling can provide comparable information for population-level surveillance. Our review covers the use of the urinary sodiu...

This paper is an exploration on why is it possible to have gameplay experiences that are perceived to be simultaneously engaging and frustrating. Particularly, the paper leverages psychological theories on rewards, frustration, and its neurobiology. In the paper (1) distinct types of (positive) frustration are informally classified. (2) The neurobiology of rewards is explained in the casual gam...

Even casual dialogue contains instances of reasoning. A paradigmatic case is the usage of Why-questions that intuitively elicit a reason for something. We present a thorough analysis of Why-questions in dialogue from a rhetorical perspective. We specify the semantics of Why-questions, i.e., we define what the space of acceptable answers is, how this acceptability is itself up for further negoti...

This paper presents WDBQL, a visual query language intended for casual users. WDBQL is a Web-based query language. It means that WDBQL implements the Web navigational mechanism to query databases. Such a mechanism has two main advantages: (i) the querying process is really easy to use for casual users and (ii) the querying process hides the semantics of the performed operations. WDBQL allows to...

This paper concerns the design of public displays that project casual awareness information, where passerby’s quickly acquire a sense of who in a small group is around and available. After describing what we mean by casual awareness, we present several prototype designs. In particular, we take awareness information garnered from a small group inhabiting a physical environment and abstract it on...

The value of contact tracing in South Glamorgan for the period May 1987 to December 1989 was assessed. Tuberculosis was diagnosed in six (3.5%) of 170 close contacts. All were young and were detected in the initial screening. Tuberculosis was not found among 441 casual contacts. The value of follow up of contacts after the initial screening and of screening casual contacts in districts with a l...

The current research scenario shows considerable work on the fundamental considerations for Cybersecurity. The physical world will fuse with the digital world in the future through enhanced technologies. However, there still exists the problem of radical uncertainty, particularly in the form of information theft. In this project we provide an analysis of the critical factors affecting the secur...

We use a stereo disparity predictor, implemented as layered neural nets in the PILUT architecture, to encode the disparity flow field for the ground plane at various viewing positions over the work space. A deviation of disparity, computed using a correspondence algorithm, from its prediction may then indicate a potential obstacle. A casual bayes net model is used to estimate the probability th...
