A semantic web rule language for geospatial domains

Retrieval of geographically-referenced information on the Internet is now a common activity. The web is increasingly being seen as a medium for the storage and exchange of geographic data sets in the form of maps. The geospatial-semantic web (GeoWeb) is being developed to address the need for access to current and accurate geo-information. The potential applications of the GeoWeb are numerous, ranging from specialised application domains for storing and analysing geo-information to more common applications by casual users for querying and visualising geo-data, e.g. finding locations of services, descriptions of routes, etc. Ontologies are at the heart of W3C's semantic web initiative to provide the necessary machine understanding to the sheer volumes of information contained on the internet. For the GeoWeb to succeed the development of ontologies for the geographic domain are crucial. Semantic web technologies to represent ontologies have been developed and standardised. OWL, the Web Ontology Language, is the most expressive of these enabling a rich form of reasoning, thanks to its formal description logic underpinnings. Building geo-ontologies involves a continuous process of update to the originally modelled data to reflect change over time as well as to allow for ontology expansion by integrating new data sets, possibly from different sources. One of the main challenges in this process is finding means of ensuring the integrity of the geo-ontology and maintaining its consistency upon further evolution. Representing and reasoning with geographic ontologies in OWL is limited. Firstly, OWL is not an integrity checking language due to it's non-unique name and open world assumptions. Secondly, it can not represent spatial datatypes, can not compute information using spatial operators and does not have any form of spatial index. Finally, OWL does not support complex property composition needed to represent qualitative spatial reasoning over spatial concepts. To address OWL's representational inefficiencies, new ontology languages have been proposed based on the intersection or union of OWL (in particular the DL family corresponding to OWL) with logic programs (rule languages). In this work, a new Semantic Web Spatial Rule Language (SWSRL) is proposed, based on the syntactic core of the Description Logic Programs paradigm (DLP), and the semantics of a Logic Program. The language is built to support the expression of geospatial ontological axioms and geospatial integrity and deduction rules. A hybrid framework to integrate both qualitative symbolic information in SWSRL with quantitative, geometric information using spatial datatypes in a spatial database is proposed. Two notable features of SWSRL are 1) the language is based on a prioritised de fault logic that allows the expression of default integrity rules and their exceptions and 2) the implementation of the language uses an interleaved mode of inference for on the fly computation (either qualitative or quantitative) deduction of spatial relations. SWSRL supports an OGC complaint spatial syntax, and a standardised definition of rule meta data. Both features aid the construction, description, identification and categorisation of designed and implemented rules within large rule sets. The language and the developed engine are evaluated using synthetic as well as real data sets in the context of developing geographic ontologies for geographic information retrieval on the Semantic Web. Empirical experiments are also presented to test the scalability and applicability of the developed framework

New Perspectives in Biblical and Rabbinic Hebrew

"Most of the papers in this volume originated as presentations at the conference Biblical Hebrew and Rabbinic Hebrew: New Perspectives in Philology and Linguistics, which was held at the University of Cambridge, 8–10th July, 2019. The aim of the conference was to build bridges between various strands of research in the field of Hebrew language studies that rarely meet, namely philologists working on Biblical Hebrew, philologists working on Rabbinic Hebrew and theoretical linguists. This volume is the published outcome of this initiative. It contains peer-reviewed papers in the fields of Biblical and Rabbinic Hebrew that advance the field by the philological investigation of primary sources and the application of cutting-edge linguistic theory. These include contributions by established scholars and by students and early career researchers.

Moving language: the language geographies of refugees and asylum-seekers in Glasgow

Over the past five years the UK has seen an increased number of refugees and asylum-seekers arriving on its shores as a result of ongoing conflicts happening around the world. Refugees and asylum-seekers make up only a very small percentage of the country’s population, yet immigration concerns regularly make headlines and are a ‘hot topic’ for politicians seeking public support. Glasgow became home for a large number of refugees and asylum-seekers after it signed up to the ‘dispersal’ scheme nearly twenty years ago, and as a result the make-up of communities in the city is everchanging. It has increased multiculturalism and is a decidedly multilingual city. This thesis brings together work in language geographies and migration studies to explore the everyday language geographies of refugees and asylum-seekers in Glasgow. The central aim is to reveal the situated dynamics of ‘talk’; what languages are used, in what combinations, and with what kinds of ‘props’ as people seek to ‘get-by’, make friends and express themselves, all the while considering the implications of the spaces involved. Through the voices of refugees, asylum-seekers and associated professionals, this thesis explores different spaces of multilingualism and the associated emotional geographies of these spaces. Language is conceptualised in this thesis as an object in itself, engendering feelings of belonging (or not), and recognises that language is fluid and mobile, mutually constituted with the space in which it happens. The thesis explores four different sites of language use - journeys to the UK, the body, the classroom, and the community - to investigate the complex geographies of refugees and asylum-seekers as they seek to acquire English and settle in the city of Glasgow. Of importance is the part that language plays in positioning refugees and asylum-seekers in society, often relating to insider-outsider type dichotomies, but also thinking about how these divides may be overcome. Finally, the refugee and asylum-seeker body is conceptualised as the mobile linguistic stranger, simultaneously near and far, and the thesis uncovers how this figure comes to be and the implications of such a conceptualisation
