This paper presents a novel approach to the task of semantic role labelling for event nominalisations, which make up a considerable fraction of predicates in running text, but are underrepresented in terms of training data and difficult to model. We propose to address this situation by data expansion. We construct a model for nominal role labelling solely from verbal training data. The best qua...

This paper presents an empirical study on the robustness and generalization of two alternative role sets for semantic role labeling: PropBank numbered roles and VerbNet thematic roles. By testing a state–of–the–art SRL system with the two alternative role annotations, we show that the PropBank role set is more robust to the lack of verb–specific semantic information and generalizes better to in...

Two major problems in constructing data federations (for example, data warehouses and database federations) concern achieving and maintaining consistency and a uniform representation of the data on the global level of the federation. The first step in creating uniform representations of data is known as data extraction, whereas data reconciliation is concerned with resolving data inconsistencie...

This paper shows how to extend RBAC sessions with dynamic aspects to deal with user switch. Users can authenticate using their functions which will create a dynamic session and automatically activate a set of privileges associated with this function. A dynamic session can be joined, leaved, restarted and reused by authorized users. Moreover, a user can switch the session to another user in orde...

car accidents are documented as a growing public health problem in iran as well as other developing countries. generally growing number of population and vehicles are not accompanied by extending road construction programs. these could be result in high death, disability, and economic loss in such country compare to develop one. this mainly affected young person who are economically more active...

The paper describes an annotation scheme for English based on Panini’s concept of karakas. We describe how the scheme handles certain constructions in English. By extending the karaka scheme for a fixed word order language, we hope to bring out its advantages as a concept that incorporates some ‘local semantics’. Our comparison with PTB-II and PropBank brings out its intermediary status between...

An on-chip deformability checker is proposed to improve the velocity–deformation correlation for red blood cell (RBC) evaluation. RBC deformability has been found related to human diseases, and can be evaluated based on RBC velocity through a microfluidic constriction as in conventional approaches. The correlation between transit velocity and amount of deformation provides statistical informati...

This paper investigates an interesting type of existential construction in Tagalog and proposes an analysis of it in terms of Role and Reference Grammar. The construction in question is known as an ‘event existential’ and is exemplified in (1), and it contrasts with a ‘plain’ or ‘nominal’ existential construction in (2). Example (1) is from Aldridge (2011), who presents a Minimalist analysis of...

In this work, we propose a new method to integrate two recent lines of work: unsupervised induction of shallow semantics (e.g., semantic roles) and factorization of relations in text and knowledge bases. Our model consists of two components: (1) an encoding component: a semantic role labeling model which predicts roles given a rich set of syntactic and lexical features; (2) a reconstruction com...
