We propose a method for labelling prepositional phrases according to two different semantic role classifications, as contained in the Penn treebank and the CoNLL 2004 Semantic Role Labelling data set. Our results illustrate the difficulties in determining preposition semantics, but also demonstrate the potential for PP semantic role labelling to improve the performance of a holistic semantic ro...

The paper describes the metrological hierarchy established for the dissemination of angle measurements from the “Dimensional Metrology Laboratory” (LAMIN) of the “National Institute of Metrology, Standardisation and Industrial Quality” (INMETRO). It shows the traceability chain from the national standard of length to the reference system, a small angle generator, and then to angle standards and...

Extending a machine learning based coreference resolution system with a feature capturing automatically generated information about semantic roles improves its performance.

We introduce a new approach to unsupervised estimation of feature-rich semantic role labeling models. 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 component: a tensor factorization model which relies on roles to predict argument fillers. When the compo...

One of the main issues in agent organizations is the specification of coordination mechanisms between agents playing roles in a regulated social environment. Both in Organizational Theory as in MAS, the concept of role plays an important role in the specification of coordination. We present a role-based model for organizations that integrates both views. Role hierarchies define the links throug...

A linking theory explains how verbs’ semantic arguments are mapped to their syntactic arguments—the inverse of the semantic role labeling task from the shallow semantic parsing literature. In this paper, we develop the computational linking theory framework as a method for implementing and testing linking theories proposed in the theoretical literature. We deploy this framework to assess two cr...

This paper presents an application of Chinese syntactic knowledge for semantic role labeling (SRL). Besides basic morphological information, syntactic structures are crucial in SRL. However, it is difficult to learn such information from limited, small-scale, manually annotated training data. Instead of manually increasing the size of annotated data, we use a large amount of automatically extra...

The Initiative of establishing Information Technology (IT) and Community Service Centers, later renamed Knowledge Stations (KSs) was launched in 2001. The KSs initiative is intended to implement IT in local communities (LCs) and remote areas in preparation for the E-Government process. This study develops a model that explores KSs’ role as a partnership in E-Government readiness in Jordan throu...

We present results for the leading hadronic contribution to the muon anomalous magnetic moment due to strange quark-connected vacuum polarisation effects. Simulations were performed using RBC–UKQCD’s Nf = 2 + 1 domain wall fermion ensembles with physical light sea quark masses at two lattice spacings. We consider a large number of analysis scenarios in order to obtain solid estimates for residu...

This paper explores Chinese semantic role labeling (SRL) for nominal predicates. Besides those widely used features in verbal SRL, various nominal SRL-specific features are first included. Then, we improve the performance of nominal SRL by integrating useful features derived from a state-of-the-art verbal SRL system. Finally, we address the issue of automatic predicate recognition, which is ess...
