Foreground and background text in retrieval

Our hypothesis is that certain clauses have foreground functions in text, while other clauses have background functions and that these functions are expressed or reflected in the syntactic structure of the clause. Presumably these clauses will have differing utility for automatic approaches to text understanding; a summarization system might want to utilize background clauses to capture commonalities between numbers of documents while an indexing system might use foreground clauses in order to capture specific characteristics of a certain document

Community Land Trusts: NEcase studies

Lack of affordable housing is recognised as a problem in most urban and rural areas in the United Kingdom today. It is one of the issues that gives rise to social exclusion of disadvantaged individuals and can contribute to weakening of community cohesion overall within a local community, mainly through people leaving to seek housing elsewhere. Arthurson, K and Jacobs, K (2003) note the concept of social exclusion is a difficult one, as cause and effect of social exclusion are almost impossible to evaluate clearly. The concept does, however, highlight the relativity of the phenomenon as exclusion implies there is something to be excluded from – in this case access to local housing that does not consume an unreasonable proportion of income. There are clearly degrees of social exclusion as Somerville, P (1998) states, expanding to make the point that some may be excluded from rented housing as well as ownership and some may be excluded only from ownership. Fundamentally Somerville puts the case that the effect of exclusion is to deny certain social groups or individuals control over their daily lives, or impairs enjoyment of their wider citizenship rights

The neo-society : realities of new socio-virtual paradigms

Chapter 14Thinking of space as a construct is by no means an easy feat. Transpose that concept from a real environment to a virtual space and blocks are not readily discernible. Th is is a world that has been immersed in digital otherness as far back as the early 1990s since the birth of the world wide web (WWW) proposal. Th ere exist two dichotomies: those pertaining to the younger generation and those to the older ones, where the former are aware of the digital fantastic worlds and the latter know the real haptic worlds, one where they can still remember that there was a time when a map was something one sought from a bookshop as against one that prompts one with the name of the street, the direction to turn, an occasional warning of a speed camera… In such a scenario, the older generation would be expected to know the physical world to a high degree and less that related to immersive technology; on the other hand the younger generation with their instant maps and online access would be expected to have a greater knowledge of their surroundings through the same access.peer-reviewe

Teaching practical science online using GIS: a cautionary tale of coping strategies

Strong demand for GIS and burgeoning cohorts have encouraged the delivery of GIS teaching via online distance education models. This contribution reviews a brief foray (2012–2014) into this field by the Open University, deploying open source GIS software to enable students to perform practical science investigations online. The “Remote observation” topic spanned four science disciplines in 6 weeks – an ambitious remit within an innovative overarching module. Documenting the challenges and strategies involved, this paper uses forum usage and student feedback data to derive insights into the student experience and the pitfalls and pleasures of teaching GIS at a distance

Content management by keywords: An analytical Study

Various methods of content analysis are described with special emphasis to keyword analysis. The paper is based on an analytical study of 97 keywords extracted from titles and abstracts of 70 research articles from INSPEC, taking ten from each year starting from 2000 to 2006, in decreasing order of relevance, on Fermi Liquid, which is a specific subject under Condensed Matter Physics. The keywords beginning with the letters ‗A‘ to ‗F‘ only are considered for this study. The keywords are indexed to critically examine its physical structure that is composed of three fundamental kernels, viz. key phrase, modulator and qualifier. The key phrase reflects the central concept, which is usually post-coordinated by the modulator to amend the central concept in accordance with the relevant context. The qualifier comes after the modulator to describe the particular state of the central concept and/or amended concept. The keywords are further classified in 36 classes on the basis of the 10 parameters, of which 4 parameters are intrinsic, i.e. associativeness, chronological appearance, frequency of occurrence and category; and remaining 6 parameters are extrinsic, i.e. Clarity of meaning, type of meaning, scope of meaning, level of perception, mode of creation and area of occurrence. The number of classes under 4 intrinsic parameters is 16, while the same under 6 extrinsic parameters are 20. A new taxonomy of keywords has been proposed here that will help to analyze research-trend of a subject and also identify potential research-areas under its scope

A Survey of Volunteered Open Geo-Knowledge Bases in the Semantic Web

Over the past decade, rapid advances in web technologies, coupled with innovative models of spatial data collection and consumption, have generated a robust growth in geo-referenced information, resulting in spatial information overload. Increasing 'geographic intelligence' in traditional text-based information retrieval has become a prominent approach to respond to this issue and to fulfill users' spatial information needs. Numerous efforts in the Semantic Geospatial Web, Volunteered Geographic Information (VGI), and the Linking Open Data initiative have converged in a constellation of open knowledge bases, freely available online. In this article, we survey these open knowledge bases, focusing on their geospatial dimension. Particular attention is devoted to the crucial issue of the quality of geo-knowledge bases, as well as of crowdsourced data. A new knowledge base, the OpenStreetMap Semantic Network, is outlined as our contribution to this area. Research directions in information integration and Geographic Information Retrieval (GIR) are then reviewed, with a critical discussion of their current limitations and future prospects

Institutional Challenges to Romania’a Regional Policy in the Perspective of Accession to the European Union

Starting with 1998, when the process of Romania’s accession to the EU was officially launched, the legal and institutional framework for regional development policy has been created, followed by the elaboration of the National Development Plan. As the programming document that builds up Romania’s access to the structural-type funds in the pre-accession period and to the structural and cohesion ones after accession to the EU, the NDP responds to both ‘internal necessities’ and ‘external requirements’, revealing the philosophy of the EU support via pre-accession instruments, which has a twofold significance: on the one hand the financial aid is viewed as a way of reducing economic and social disparities between the candidate and the EU member countries; on the other hand, working with pre-accession instruments, creating the institutional framework for measures implementation, action monitoring and impact evaluation allow the candidate countries’ authorities to get used to European Commission’s procedures and, thus, to be prepared for the administration of the much higher amounted financial funds after accession to the EU. Though, in the case of Romania the institutional framework for regional development policy has suffered a lot of changes since 1998, with negative consequences on the absorption capacity of EU funds, serving as a good example for explaining why so many times Romania has been severely criticised by EU for institutional instability and delays in institutional reform. This paper proposes an analysis of Romania’s regional development policy in the perspective of accession to the European Union, with a particular emphasis on the institutional transformations and future challenges, especially those referring to the post-accession period. The author’s contribution to a recent study on Romania’s capacity to absorb the EU funds (developed under the auspices of the European Institute of Romania) will be presented, offering an evaluation of the components that characterise the administrative capacity of absorption in programming field.
