In 1986, van Rijsbergen promotes a principle in which the matching between a query and a document is founded on a form of uncertain logical inference. His formulation was deliberately abstract, no attempt was made to specify how such a principle might be implemented through an effective logic and under a particular semantics. In classical logics inference which is often associated with logical ...
The integration of different library catalogues into a union catalogue is a desirable goal in order to extend the available information and to ease the user’s access as well as to improve the user friendliness. Such a catalogue integration is no straight forward process because of the diversity and peculiarities of the involved sourcesystems. This article describes some of the problems the auth...
Norms impose obligations, permissions and prohibitions on individual agents operating as part of an organisation. Typically, the purpose of such norms is to ensure that an organisation acts in some socially (or mutually) beneficial manner, possibly at the expense of individual agent utility. In this context, agents are normaware if they are able to reason about which norms are applicable to the...
This paper identifies the main concepts involved in the study of epigraphy and proposes the use of CIDOC CRM to encode epigraphic concepts and to model the scientific process of investigation related to the study of epigraphy. After analysing the existing CIDOC CRM entities and those provided by the CRMsci and CRMarchaeo extensions, we introduce more specific epigraphic classes to be used as th...
Data integration systems provide access to a set of heterogeneous, autonomous data sources through a so-called global, or mediated view. There is a general consensus that the best way to describe the global view is through a conceptual data model, and that there are basically two approaches for designing a data integration system. In the global-as-view approach, one defines the concepts in the ...
The categorical compositional approach to meaning has been successfully applied in natural language processing, outperforming other models in mainstream empirical language processing tasks. We show how this approach can be generalized to conceptual space models of cognition. In order to do this, first we introduce the category of convex relations as a new setting for categorical compositional s...
Is conceptual relativity a genuine phenomenon? If so, how is it properly understood? And if it does occur, does it undermine metaphysical realism? These are the questions we propose to address. We will argue that conceptual relativity is indeed a genuine phenomenon, albeit an extremely puzzling one. We will offer an account of it. And we will argue that it is entirely compatible with metaphysic...
Objectives: Hypertension is a global major health challenge and mechanisms related to the risk factors associated with it are poorly understood. Therefore, we used structural modeling to test a hypothesized model to identify factors associated with hypertension. Methods: A cross-sectional population based survey, was performed and the data related to a random representative sample of 9704 sub...
in this study market orientation of iran commercial banks has been considered as an effective factor on banks' performance and the relationship between them has been surveyed. accordingly a conceptual model has been developed that shows both direct and indirect (through value creation) relationship. the developed conceptual model has been evaluated by bank and marketing experts in the fram...
A method of mapping sets of uninterpreted record or relation schemes into entity-relationship diagrams is described and then applied to two conceptual design problems. First, the method is applied to the design of relational databases. It is shown that the method can be interpreted as a normalization procedure that maps a given relational schema into a new schema that represents an entity-relat...
