title: User-guided Disambiguation for Semantic-enriched Search

authors: Ren, Xinning

abstract: In this thesis, we develop, implement and evaluate a strategy for user-guided disambiguation for semantic-enriched search. We use the prototype system Capisco that combines some features of traditional text-based search engines and semantic search engines. Unlike many semantic search approaches that require formulating queries in quite complex semantic languages, the Capisco system is a keyword-based search engine. 

In this work, we focus on the user-guided disambiguation which helps to capture the users’ information needs. The user-guided disambiguation developed in this thesis explores the semantic meanings for a user-provided keyword and displays these to the users for selection. We explored three different orderings in which the possible keyword meanings may be shown. Using our newly-developed disambiguation interface, the user selects one or several of these meanings from the list offered. The selected semantic meanings are then transferred to the search engine to identify matching documents. 

This thesis provides an analysis of related work on search interfaces in semantic search, and in methods for semantic disambiguation. We developed the concept of user-guided disambiguation and implemented this concept in a prototype that explored three interface variations. We executed a user study on the three interface alternatives. Finally, we discuss the insights gained during this project, compare our approach to existing literature, and explore possible future work.

title: Chief Amongst The Angels?  International Prosecutors And The Modernist Project

authors: Rogers, Damien Robert

subjects: International Criminal Law

abstract: This thesis argues that three successive generations of prosecutors—each of whom at some moment in time belong to a major institution designed specifically to enforce international criminal law—are best understood as agents of the law, politics and war.  By examining the relevant institutional arrangements, including formal prosecutorial mandates, the thesis recognises that these prosecutors play vital roles in the enforcement of international criminal law.  By critically examining prosecutorial performance during the pre-trial and trial phases this thesis contends, firstly, that these prosecutors are also political actors serving, unwittingly or otherwise, in the interests of economic liberalisation, expressed as neo-capitalism during the middle of the twentieth century or as neoliberalism in the late twentieth century.  By foregrounding the material and ideational conditions giving rise to those major enforcement institutions this thesis contends, secondly, that international prosecutors also help wage a mostly silent and largely unacknowledged war fought by proponents of various utopian movements.  In order to support these two main contentions the thesis situates the development of international criminal law and its major institutions as a significant temporality of a discourse against politico-cruelty, a term used here to refer to cruel acts committed as a means of achieving some substantive end.  It also contextualises the collective prosecutorial efforts within the project of modernity and, more specifically, what is described here as a politico-cultural civil war fought for control over that project.  Using international criminal law as a means of confronting humanity’s worst excesses and curbing modernity’s most violent pathologies, international prosecutors of war crimes, crimes against humanity, crimes of genocide and crimes of aggression might represent the vanguard in the quest for international criminal justice and be regarded by many as featuring among humanity’s better angels.  Indeed, they might well be characterised in world affairs as chief amongst the angels.  But, at the same time, these politico-legal actors, whose mandates are derived from, and re-inscribe, particular configurations of power emerging in the aftermath of global conflict, need to be recognised as the auxiliary combatants of those seeking to maintain their control over the modernist project.

title: Māori social identities in New Zealand and Hawai'i

authors: Nikora, Linda Waimarie

subjects: Maori

abstract: This research is comprised of two narrative interview studies of Māori in two different settings, New Zealand (n=20) and Hawai'i (n=30).  The data was gathered over the 1994-1996 period.  The two settings have some commonalities and differences.  In both settings Māori are required to make decisions about the continuity of their ethnic Māori identities and hereditary cultural identities of iwi, hapu and whanau, and the part that they wish these identities to play in their daily lives.  The focus of this research was about how Māori create meaning in their lives and maintain their social identities across and within those contexts they move through. 

The findings of this research suggest that Māori in New Zealand continue to value and gain meaning and satisfaction from their cultural collectivities and the social identities derived from them.  However, the results tend to suggest that there are changes in the ways that individuals conceptualise these identities and concomitantly, how they see of themselves.
For New Zealand participants, conceptions of hapu and iwi appear to be converging with an increasing focus on the physicality of marae, its environment and symbolism, and the social events and relationships negotiated in that space.  New Zealand participants saw some hapu and iwi maintenance activities as more legitimate than others.  More value was placed on returning to hapu and iwi homelands however irregular these returns were.  In contrast, conceptions of hapu and iwi held by participants in Hawai'i seemed less intense.  There were few opportunities to engage with other hapu or iwi members.  Being Māori had greater meaning and was understood, probed and valued by others in the culturally plural context of Hawai'i.  For New Zealand participants, being Māori was enacted in the context of being a discriminated, negatively constructed minority.  All were aware of the defining effect that the presence of a dominant majority could have and countered these effects by engaging in social justice and in-group solidarity activities.

The changing identity conceptions held by members of Māori social groups will have implications for a sense of community and social cohesion, for tribal asset management, service delivery and crown settlement processes.  If Māori are redefining and renegotiating their social identities to achieve greater meaning and satisfaction then these changes are important to respond to and recognise.
