Pruning-based identification of domain ontologies

We present a novel approach of extracting a domain ontology from large-scale thesauri. Concepts are identified to be relevant for a domain based on their frequent occurrence in domain texts. The approach allows to bootstrap the ontology engineering process from given legacy thesauri and identifies an initial domain ontology that may easily be refined by experts in a later stage. We present a thorough evaluation of the results obtained in building a biosecurity ontology for the UN FAO AOS project

Invariant-based approach to symmetry class detection

In this paper, the problem of the identification of the symmetry class of a given tensor is asked. Contrary to classical approaches which are based on the spectral properties of the linear operator describing the elasticity, our setting is based on the invariants of the irreducible tensors appearing in the harmonic decomposition of the elasticity tensor [Forte-Vianello, 1996]. To that aim we first introduce a geometrical description of the space of elasticity tensors. This framework is used to derive invariant-based conditions that characterize symmetry classes. For low order symmetry classes, such conditions are given on a triplet of quadratic forms extracted from the harmonic decomposition of the elasticity tensor $C$, meanwhile for higher-order classes conditions are provided in terms of elements of $H^{4}$, the higher irreducible space in the decomposition of $C$. Proceeding in such a way some well known conditions appearing in the Mehrabadi-Cowin theorem for the existence of a symmetry plane are retrieved, and a set of algebraic relations on polynomial invariants characterizing the orthotropic, trigonal, tetragonal, transverse isotropic and cubic symmetry classes are provided. Using a genericity assumption on the elasticity tensor under study, an algorithm to identify the symmetry class of a large set of tensors is finally provided.Comment: 32 page

Realising benefits in primary healthcare infrastructures

Purpose: This paper focuses upon the requirements to manage change, tangible and intangible benefits in a joint approach to deliver outputs on time, to quality and cost without failing to realise the benefits of the change. The aim of the paper is to demonstrate the need for benefits driven programme/project management as well as the importance of identifying the stakeholders’ level of involvement and contribution throughout the process, and manage their expectations. Design/methodology/approach: The methodology used is based on an action research approach, combining findings from a literature review and case studies within UK’s primary healthcare sector. Findings: Findings demonstrate development of a Benefits Realisation (BeReal) approach in healthcare through looking at case studies taking place within UK’s primary and acute healthcare sector Research limitations/implications: The framework development is based upon theoretical evidence and further research is needed to test and validate its robustness. Originality/value: The application of Benefits Realisation and Management in developing and delivering primary healthcare facilities. Keywords: Benefits management, Benefits realisation, healthcare infrastructures, process and LIF
