In Korean information retrieval, compound nouns play an important role in improving precision in search experiments. There are two major approaches to compound noun indexing in Korean: statistical and linguistic. Each method, however, has its own shortcomings, such as limitations when indexing diverse types of compound nouns, over-generation of compound nouns, and data sparseness in training. In this paper, we propose a corpus-based learning method, which can index diverse types of compound nouns using rules automatically extracted from a large corpus. The automatic learning method is more portable and requires less human effort, although it exhibits a performance level similar to the manual-linguistic approach. We also present a new filtering method to solve the problems of compound noun over-generation and data sparseness.  相似文献

The FIFA World Cup for men (hereafter referred to as the FIFA World Cup) is possibly the biggest global media event. Winning or losing often gives rise to expressions of collective degrees of national pride or disappointment. But, it is not only the performance of the teams that is of significance in this respect; the devotion of fans to the game and their loyalty to their own national team are also an important vehicle of identity and self-affirmation as a nation. Thus, no country can afford to dispense with the travelling model of the enthusiastic fan as a representative of national identity. Through an ethnographic study of Ghana’s state-financed fan trip to the FIFA World Cup 2010 in South Africa, we will show how the actors involved (government, opposition, fans and media) negotiate national identity and representation.  相似文献

Good community consultation is a powerful tool in developing new museum projects and exhibitions, facilitating a more effective delivery of service to a diverse public. Existing techniques for both user and community consultation are limited with front end evaluation particularly undeveloped in the sector, often providing no meaningful base by which to compare project outcomes. Tension exists between government, which values quantitative data, and researchers who argue qualitative methods are more appropriate for evaluating community projects. This article reports a pilot study using the repertory grid technique to examine a ‘socially excluded’, ethnically diverse local community's perceptions, expectations and previous experiences of similar projects, to provide a benchmark against which to compare outcomes. This research formed part of the front end evaluation for a New Deal for Community's Project run by Sheffield Galleries and Museums Trust. The repertory grid technique was developed in psychological studies as a means of understanding respondents' own world views, and is particularly helpful in working with people with poor language skills. Although this study only used the technique qualitatively, it can be used to combine both quantitative and qualitative data, providing more robust data for evidence-based policy decisions. Using the repertory grid technique, respondents were able to list both perceived and practical barriers to participation in projects. The technique also enabled them to articulate what would motivate them to become involved in future projects. The repertory grid technique has significant potential for use in community consultation and project evaluation as a means of understanding local residents' perceptions and its visual representation means that its findings can be easily understood by participants, policy-makers and practitioners.  相似文献

Across the Western world, membership in the established organized churches is on the decline with a concomitant reduction in the need for churches and church halls. As redundant and unused churches are the focus of vandalism and decay, owners and heritage managers are looking for options to adaptively re-use such buildings. This article reviews the literature on the re-use of churches in the Netherlands, which has long history of innovatively addressing the problems. The options available range from re-use for religious purposes by other denominations or faiths, to community use (multi-purpose, sport, music etc.), and private use, which can be either commercial or residential. The attitudes of the community and the original property owners play a major part in successful adaptive re-use. Because of its long history, the Dutch experience in adaptive re-use of religious buildings has much to offer heritage managers in other countries faced with this emergent management issue.  相似文献

Comparing rankings of search results on the Web   总被引:1,自引:0,他引:1  
The Web has become an information source for professional data gathering. Because of the vast amounts of information on almost all topics, one cannot systematically go over the whole set of results, and therefore must rely on the ordering of the results by the search engine. It is well known that search engines on the Web have low overlap in terms of coverage. In this study we measure how similar are the rankings of search engines on the overlapping results.We compare rankings of results for identical queries retrieved from several search engines. The method is based only on the set of URLs that appear in the answer sets of the engines being compared. For comparing the similarity of rankings of two search engines, the Spearman correlation coefficient is computed. When comparing more than two sets Kendall’s W is used. These are well-known measures and the statistical significance of the results can be computed. The methods are demonstrated on a set of 15 queries that were submitted to four large Web search engines. The findings indicate that the large public search engines on the Web employ considerably different ranking algorithms.  相似文献
