Abstract:Oil is undoubtedly the most important, and at the same time, the most politico-economic commodity in today’s world. As the most important source of economic and political power, oil has constantly played a significant role for Iranian governments both before and after the revolution [1979], and has served as a major fuel for their economic power. However, historical experience in...

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...

The purpose of this paper is control of simply supported flexible core sandwich beam's linear vibration equipped with piezoelectric patches under different loads. The effects of external forces imposed on sandwich beam can be reached to a minimum value by designing an appropriate controller and control the beam's vibration. Three-layer sandwich beam theory is used for analytical modeling of san...

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...
