“…It is our belief that IVEA can demonstrate that it provides immediate benefits by taking advantage of the defined personal ontology to provide the users with a personal lens to look at text collections from different perspectives. Furthermore, we proposed in [23] the use of the PIMO (Personal Information Model) ontology [17], which serves as a formal representation of concepts and structures within a user's mental model, to minimize the cost of creating a personal ontology. The users only need to extend this readily built ontology with concepts and instances of interest to them.…”

In this paper, we present an interactive matrix-based multi-dimensional visualization component which enables the users to explore a text collection along different conceptual dimensions. Of importance in our approach are the tight coupling of the users' personal ontologies representing their spheres of interest with the visualization component and the application of barycenter heuristic for edge crossing minimization to enhance its visual display. We also discuss how IVEA, the information visualization tool containing the proposed component, can address the commonly perceived constraints of building a personal ontology from scratch for IVEA to work.

“…were the main focus of this research: its methodology, its finances and its safeguards. The study began with an exploratory review (Thai et al 2008) of a range of documents (Table 1) so as to identify actors involved in designing REDD?. Actors included States and non-State organisations and groups (Keeley and Scoones 2003) who have An in-depth iterative content analysis of documents was then undertaken to explore actor roles in designing REDD?…”

Emerging climate change regimes, such as the mechanism for reducing emissions from deforestation and forest degradation (REDD?), are increasingly aiming to engage developing countries such as those in Africa, in sustainable development through carbon markets. The contribution of African countries to global climate negotiations determines how compatible the negotiated rules could be with the existing socioeconomic and policy circumstances of African countries. The aim of this paper is to explore the agency of Africa (African States) in the global climate change negotiations and discuss possible implications for implementing these rules using REDD? as a case study. Drawing on document analysis and semi-structured expert interviews, our findings suggest that although African countries are extensively involved in the implementation of REDD? interventions, the continent has a weak agency on the design of the global REDD? architecture. This weak agency results from a number of factors including the inability of African countries to send large and diverse delegations to the negotiations as well lack of capacity to generate and transmit research evidence to the global platform. African countries also perceive themselves as victims of climate change who should be eligible for support rather than sources of technological solutions. Again, Africa's position is & Joanes Odiwuor Atela fragmented across negotiation coalitions which weakens the continent's collective influence on the REDD? agenda. This paper discusses a number of implementation deficits which could result from this weak agency. These include concerns about implementation capacity and a potential lack of coherence between REDD? rules and existing policies in African countries. These findings call for a rethink of pathways to enhancing Africa's strategies in engaging in multilateral climate change negotiations, especially if climate change regimes specifically targeted at developing countries are to be effective.

“…For example, an ontology-based visualization tool, AutoFocus, was proposed to display search results for documents on the desktop as clusters of populated concepts. Thai, Handschuh, and Decker (2008) presented IVEA (Information Visualization for Exploratory Document Collection Analysis), a visualization tool that employs the PIMO (personal information model) ontology to provide knowledge workers with an interactive interface, allowing them to browse for information in a personalized manner. Differing from existing ontologybased visualization tools' focus on information visualization, Clonto focuses on identifying key concepts, exploiting their relationships using WordNet, and visualizing the documents through those key concepts.…”

Exploiting corpus‐related ontologies for conceptualizing document corpora

As a greater volume of information becomes increasingly available across all disciplines, many approaches, such as document clustering and information visualization, have been proposed to help users manage information easily. However, most of these methods do not directly extract key concepts and their semantic relationships from document corpora, which could help better illuminate the conceptual structures within given information. To address this issue, we propose an approach called "Clonto" to process a document corpus, identify the key concepts, and automatically generate ontologies based on these concepts for the purpose of conceptualization. For a given document corpus, Clonto applies latent semantic analysis to identify key concepts, allocates documents based on these concepts, and utilizes WordNet to automatically generate a corpus-related ontology. The documents are linked to the ontology through the key concepts. Based on two test collections, the experimental results show that Clonto is able to identify key concepts, and outperforms four other clustering algorithms. Moreover, the ontologies generated by Clonto show significant informative conceptual structures.
