This paper describes a supervised, knowledge-intensive approach to the automatic identification of semantic relations between nominals in English sentences. The system employs different sets of new and previously used lexical, syntactic, and semantic features extracted from various knowledge sources. At SemEval 2007 the system achieved an F-measure of 72.4% and an accuracy of 76.3%.

Many languages, including Modern Standard Arabic (MSA), insert resumptive pronouns in relative clauses, whereas many others, such as English, do not, using empty categories instead. This discrepancy is a source of difficulty when translating between these languages because there are words in one language that correspond to empty categories in the other, and these words must either be inserted o...

Supply chain tracking information has always been an enabler for effective and efficient business operations. In this paper we propose a way to model supply chain tracking information in order to determine its quality with regard to its ability to support business decisions. The analysis provides insights on the way that tracking information accuracy and timeliness affect decision effectiveness...

This paper analyzes profile data and contact patterns of conference participants in a social and ubiquitous conferencing scenario: We investigate user-interaction and community structure of face-to-face contacts during a conference, and examine different roles and their characteristic elements. The analysis is grounded using real-world conference data capturing descriptive profile information a...

Background Monitoring in randomized trials is recommended as part of International Conference on Harmonisation Good Clinical Practice standards. On-site monitoring in multicentre trials is common but is costly and can be inefficient. Central statistical monitoring can be used to detect unusual data patterns, identify intentional or unintentional trial misconduct, and to prioritise on-site visit...

Light verb constructions (LVCs), such as take a walk and make a decision, are a common subclass of multiword expressions (MWEs), whose distinct syntactic and semantic properties call for a special treatment within a computational system. In particular, LVCs are formed semi-productively: often a semantically-general verb (such as take) combines with a number of semantically-similar nouns to form...

been proposed. This paper first compares the strengths and weaknesses of these mechanisms, and evaluates possible impacts of threats to RFID. Subsequently, a track-and-trace anti-counterfeiting system using RFID is proposed. The proposed system is aimed at relatively high-end consumer products, and it helps protect genuine products by maintaining the product pedigree and the supply chain integr...

This case report presents an eight-year-old girl having periauricular swelling and severe pain during mouth opening on the right-side temporomandibular joint (TMJ). CBCT showed extensive destruction of the base of the skull and the roof of the glenoid fossa on the right side. The findings based on CT and MRI images with and without contrast are discussed herein. This report highlights a skull b...

In this paper, we present an approach to the automatic identification and correction of preposition and determiner errors in nonnative (L2) English writing. We show that models of use for these parts of speech can be learned with an accuracy of 70.06% and 92.15% respectively on L1 text, and present first results in an error detection task for L2 writing.
