An ontology-based mining approach for user search intent discovery

Discovering proper search intents is a vi- tal process to return desired results. It is constantly a hot research topic regarding information retrieval in recent years. Existing methods are mainly limited by utilizing context-based mining, query expansion, and user profiling techniques, which are still suffering from the issue of ambiguity in search queries. In this pa- per, we introduce a novel ontology-based approach in terms of a world knowledge base in order to construct personalized ontologies for identifying adequate con- cept levels for matching user search intents. An iter- ative mining algorithm is designed for evaluating po- tential intents level by level until meeting the best re- sult. The propose-to-attempt approach is evaluated in a large volume RCV1 data set, and experimental results indicate a distinct improvement on top precision after compared with baseline models.

Criação de uma Lista de Cabeçalhos de Assunto para a Documentação da Biblioteca Universitária João Paulo II

O aspecto fulcral desta dissertação centra-se-à volta do desafio de procurar facilitar o acesso à informação contida na base de dados bibliográfica da Biblioteca Universitária João Paulo II (BUJPII) da Universidade Católica Portuguesa (UCP) cujo conteúdo temático tem sido até agora representado pela Classificação Decimal Universal (CDU), linguagem documental pouco acessível a grande parte dos nossos utilizadores, na sua maioria estudantes universitários que a consideram um instrumento de pesquisa pouco amigável porque estão muito pouco ou nada familiarizados com este tipo de classificação numérica preferindo o uso de palavras-chave no acesso ao conteúdo temático das obras. Com este objectivo em vista, propusemo-nos levar a cabo este trabalho de investigação fazendo a harmonização (correspondência) entre as notações da CDU, usada na classificação da colecção de fundos da BUJPII e uma lista simplificada de Cabeçalhos de Assunto da Biblioteca do Congresso, com o propósito de iniciar um processo de atribuição de cabeçalhos de assunto, mapeados a partir das notações da CDU, a parte dos referidos fundos, cuja recuperação de conteúdo tem sido feita até agora através da Classificação Decimal Universal. O estudo incidiu experimentalmente numa amostragem de monografias de áreas não indexadas mas já classificadas, cujos registos bibliográficos se encontram na base de dados da Biblioteca Universitária João Paulo II. O projecto consistiu na atribuição de cabeçalhos de assunto, traduzidos manualmente para português a partir da lista em inglês dos Cabeçalhos de Assunto da Biblioteca do Congresso (LCSH). Procurou-se que estivessem semanticamente tão próximos quanto possível dos assuntos que correspondiam às notações da Classificação Decimal Universal (CDU) com as quais as monografias tinham sido anteriormente classificadas. O trabalho foi primeiro elaborado de forma manual e depois “carregado” no software Horizon, dado ser este o sistema informático de gestão integrada em uso na Biblioteca Universitária João Paulo II, sendo o objectivo futuro a indexação de todas as áreas do seu acervo bibliográfico, como forma complementar privilegiada no acesso à informação.

Theories of international relations

This collection of essays demonstrates the continuing importance of the work of Michael Polanyi for the understanding, not only of the great events of the 20th century, but also of the problems that face us in the 21st century. Polanyi moved liberalism away from a negative, sceptical and rationalist basis towards an acceptance of trust, tradition and faith in transcendent values. His conception of the free society is not one merely of doing as one pleases nor vacuously 'open', but one of individual and communal self-dedication to those values and ideals.These essays, authored by a distinguished international and interdisciplinary panel of invited contributors, examine Polanyi's specific insights in the theory of knowledge, the nature and source of social order and the philosophy of economics and science and draw relevant comparisons between Polanyi and related thinkers such as Popper, Hayek and Mises. This book shows the sources of Polanyi's ideas and his distinctive contribution to philosophy generally, to social and political thought and to economics.

Tags in the Catalogue: Insights From a Usability Study of LibraryThing for Libraries

Library of Congress Subject Headings (LCSH), the standard subject language used in library catalogues, are often criticized for their lack of currency, biased language, and atypical syndetic structure. Conversely, folksonomies (or tags), which rely on the natural language of their users, offer a flexibility often lacking in controlled vocabularies and may offer a means of augmenting more rigid controlled vocabularies such as LCSH. Content analysis studies have demonstrated the potential for folksonomies to be used as a means of enhancing subject access to materials, and libraries are beginning to integrate tagging systems into their catalogues. This study examines the utility of tags as a means of enhancing subject access to materials in library online public access catalogues (OPACs) through usability testing with the LibraryThing for Libraries catalogue enhancements. Findings indicate that while they cannot replace LCSH, tags do show promise for aiding information seeking in OPACs. In the context of information systems design, the study revealed that while folksonomies have the potential to enhance subject access to materials, that potential is severely limited by the current inability of catalogue interfaces to support tag-based searches alongside standard catalogue searches.

Zerbrochene Spiegel /1

Der Beitrag beschreibt eine doppelte, verfremdete und letztendlich tragische Spiegelung in der Wahrnehmung von Architektur zwischen Europa und Indien: zwischen 1780 und 1856 entstanden in der nordindischen Stadt Lucknow mehrere große Baukomplexe, die von den indisch-islamischen Herrschern der Stadt in europäisch-klassizistischen Formen gestaltet wurden. Nach dem indischen Aufstand, der in den Jahren 1857 und 1858 gegen die britische Herrschaft in Lucknow losbrach, wurden diese Bauten zum Gegenstand einer scharfen europäischen Architekturkritik. Der erste Abschnitt – "Das Eigene und das Fremde" – betrachtet die westliche Rezeption dieser europäisch-klassizistischen Bauten, die über Jahrzehnte durch ein Negativurteil bestimmt war, das sich aus der politischen Interpretation des indischen Aufstands erklärt. Der zweite Abschnitt – "Kopie und Synthese" – geht auf die Suche nach den Zusammenhängen für die positive Europarezeption in Lucknow und für die negative Kritik dieser Bauten in Europa. Es erweist sich, dass die Praxis von Architekturkopie und die Wahrnehmung europäischer Stilformen bei der Übernahme klassizistischer Motive in Indien deutlich anders war als das exakte und moralisch überhöhte Verständnis von Stilformen im Europa nach 1850.

Igbo Nationalism and Biafra

When I was living in Igboland in 1993 and from 1994 to 1996, there was not much talk about Biafra, the secessionist republic that had been defeated by the Nigerian army in 1970. Not one Igbo politician suggested that his or her people in the southeast of Nigeria should secede again and proclaim a second Biafra. Since 1984, Nigeria had been ruled by the military, and political hopes focused on a return to democracy. Democracy did come in 1999, but it proved a big disappointment. It did not end the marginalisation of the Igbo but led to an increase in the number of ethnic and religious clashes, with Igbo 'migrants' in northern Nigeria as the main victims. It was Nigeria's fourth transition to democracy, and the Igbo lost out again. When I returned to Igboland for brief visits between 2000 and 2007, the option of a new Biafra was widely discussed. Many of my former colleagues at the University of Nsukka seemed to be in favour of the secession project. I talked to supporters of the main separatist organisation, Movement for the Actualisation of a Sovereign State of Biafra (MASSOB), and I discussed the project with members of Ohanaeze, a loose association of Igbo politicians, most of whom had distanced themselves from radical secessionism. In order to learn more about the resurgence of Igbo nationalism, I collected Igbo periodicals. A few of them, such as the New Republic, resembled newspapers; others, like News Round, Eastern Sunset or Weekly Hammer (with eight pages in A4 size), looked more like political pamphlets. Street vendors used back issues as wrapping paper, so they were easy to get. Most of them had been edited not in Igboland, but in Lagos, Nigeria's commercial centre and former capital which is home to a huge Igbo diaspora. Though written in English, these publications are addressed exclusively to an Igbo readership, discussing global and domestic affairs from a nationalist point of view. Articles printed here, no matter their topic, are nationalist in the sense that they assess things from the standpoint of Igbo interests. The same is true of many articles on Igbo websites and of some books and brochures written for an Igbo audience. Another source of information on Igbo nationalism are statements by Igbo governors, ministers, members of parliament and other professional politicians who are quoted in newspapers, such as Vanguard or Guardian, and in weekly magazines such as Newswatch, Tell or The News – all with a Nigeria-wide circulation and a multi-ethnic readership. Nigeria's papers and magazines are among the best in Africa. They try to be balanced in their coverage of ethnic conflicts, and they give reliable information. The same cannot be said of periodicals produced by Igbo nationalists. They provide space for Igbo all over the world to voice their opinions, and they tolerate much controversy, but they are not accurate when reporting facts.

The sociolinguistic situation of ǂHoan, a moribund 'Khoisan' language of Botswana

In 2010, we conducted a sociolinguistic survey on the moribund 'Khoisan' language ǂHoan (Ju-ǂHoan), spoken in Botswana at the fringe of the Kalahari Desert. The survey aimed at investigating language use, degrees of multilingualism and language attitude among the ǂHoan speakers. Data collection was done on the basis of a questionnaire. We found that the positive language attitude of individuals towards ǂHoan often conflicts with the community's attitude towards this language, resulting in a split of actual language use between the family and more formal situations. All ǂHoan speakers are at least bilingual speaking the local lingua franca Kgalagadi (Bantu) besides ǂHoan. Most of them are in fact even trilingual, speaking Gǀui (Khoe-Kwadi) in addition to ǂHoan and Kgalagadi. Most of our results stand in line with an earlier sociolinguistic survey on ǂHoan by Batibo (2005a) which was carried out in 2003. In comparing Batibo's results to ours, changes in the sociolinguistic situation of ǂHoan as well as differences between the different villages will be pointed out.
