Karen Spärck Jones is one of the major figures of 20th century and early 21st Century computing and information processing. Her ideas have had an important influence on the development of Internet Search Engines. Her contribution has been recognized by awards from the natural language processing, information retrieval and artificial intelligence communities, including being asked to present the prestigious Grace Hopper lecture. She continues to be an active and influential researcher. Her contribution to the scientific evaluation of the effectiveness of such computer systems has been quite outstanding. This book celebrates the life and work of Karen Spärck Jones in her seventieth year. It consists of fifteen new and original chapters written by leading international authorities reviewing the state of the art and her influence in the areas in which Karen Spärck Jones has been active. Although she has a publication record which goes back over forty years, it is clear even the very early work reviewed in the book can be read with profit by those working on recent developments in information processing like bioinformatics and the semantic web.

The ?fth campaign of the Cross-Language Evaluation Forum (CLEF) for Eu- pean languages was held from January to September 2004. Participation in the CLEF campaigns has increased each year and CLEF 2004 was no exception: 55 groups submitted results for one or more of the di?erent tracks compared with 42 groups in the previous year. CLEF 2004 also marked a breaking point with respect to previous campaigns. The focus was no longer mainly concentrated on multilingual document retrieval as in previous years but was diversi?ed to include di?erent kinds of text retrieval across languages (e. g. , exact answers in the question-answering track) and retrieval on di?erent kinds of media (i. e. , not just plain text but collections containing image and speech as well). In ad- tion, increasing attention was given to issues that regard system usability and user satisfaction with tasks to measure the e?ectiveness of interactive systems or system components being included in both the cross-language question - swering and image retrieval tasks with the collaboration of the coordinators of the interactive track. The campaign culminated in a two-and-a-half-day workshop held in Bath, UK, 15–17 September, immediately following the 8th European Conference on Digital Libraries. The workshop was attended by nearly 100 researchers and s- tem developers.

The second evaluation campaign of the Cross Language Evaluation Forum (CLEF) for European languages was held from January to September 2001. This campaign proved a great success, and showed an increase in participation of around 70% com pared with CLEF 2000. It culminated in a two day workshop in Darmstadt, Germany, 3–4 September, in conjunction with the 5th European Conference on Digital Libraries (ECDL 2001). On the first day of the workshop, the results of the CLEF 2001 evalua tion campaign were reported and discussed in paper and poster sessions. The second day focused on the current needs of cross language systems and how evaluation cam paigns in the future can best be designed to stimulate progress. The workshop was attended by nearly 50 researchers and system developers from both academia and in dustry. It provided an important opportunity for researchers working in the same area to get together and exchange ideas and experiences. Copies of all the presentations are available on the CLEF web site at http://www. clef campaign. org. This volume con tains thoroughly revised and expanded versions of the papers presented at the work shop and provides an exhaustive record of the CLEF 2001 campaign. CLEF 2001 was conducted as an activity of the DELOS Network of Excellence for Digital Libraries, funded by the EC Information Society Technologies program to further research in digital library technologies. The activity was organized in collabo ration with the US National Institute of Standards and Technology (NIST).

This book investigates the dynamics and challenges of ethnicity and elite politics in Nigeria.

Drawing on original fieldwork in Nigeria, Portia Roelofs argues for an innovative re-conceptualisation of good governance. Contributing to debates around technocracy, populism and the survival of democracy amidst conditions of inequality and mistrust, Roelofs offers a new account of what it means for leaders to be accountable and transparent. Centred on the rise of the 'Lagos Model' in the Yoruba south-west, this book places the voices of roadside traders and small-time market leaders alongside those of local government officials, political godfathers and technocrats. In doing so, it theorises 'socially-embedded' good governance. Roelofs demonstrates the value of fieldwork for political theory and the associated possibilities for decolonising the study of politics. Challenging the long-held assumptions of the World Bank and other international institutions that African political systems are pathologically dysfunctional, Roelofs demonstrates that politics in Nigeria has much to teach us about good governance.

This volume deftly undertakes both a theoretical deconstruction of the concept of civil society (and related themes, including civility) and an empirical analysis of the radicalization process in Southern Nigeria .

Elections have been central to regime collapse in Nigeria because they neither passed the test of citizens' acceptability nor electoral neutrality. They always pushed the country to a dangerous brink which she has often survived after serious constitutional and political bruises. The general election of 1964 rocked the delicate balance of the country resulting in the military coup of January 15, 1966 and a thirty month civil war. The subsequent effort of the military at restructuring the country did not go far enough to win the civic confidence of the people. The military availed itself of another opportunity of tinkering with the system in 1993. However, it demonstrated that it was not immune to civic dishonesty when it annulled the widely acclaimed free and fair presidential election in June 12, 1993. By fits and starts, Nigeria held another election in 1999 which was tolerated only because of citizens' fatigue of military rule. The elections of 2003 and 2007 were classic examples of make-belief democracy. The feeding of inequity and, if you will, domination, persisted. A combination of fortune, trickery and arm twisting produced a power shift in favour of Dr. Goodluck Ebele Azikwe Jonathan in April 2011. The subsequent attempt by the north to create a strategic consensus did not save it from being pushed into fringe politics forcing some of its spokespersons to vow that they will make governance impossible. The election was better than the worst but much still remains to be done.
