We present a new approach for the representation of search results in a graphical user interface that allows navigating and exploring these results. An interactive matrix display is used for showing the hyperlinks of a site search or other search queries in different hierarchical category systems. The results of a site search are not only shown as a list, but also classified in an ontology-based category system. So the user has the possibility to explore and navigate within the results of his query. The system offers a flexible way to refine the query by drilling down in the hierarchical structured categories. The user can explore the results in one category with the so called List Browser or in two categories at the same time with the so called Matrix Browser (Ziegler et al. 2002). A familiar and well known interactive tree widget is used for the presentation of the categories and located hyperlinks, so the handling of the system is very intuitive.
我们提出了一种在图形用户界面中表示搜索结果的新方法，该方法允许导航和探索这些结果。交互式矩阵显示用于在不同的层次分类系统中显示站点搜索或其他搜索查询的超链接。站点搜索的结果不仅以列表的形式显示，而且还在基于本体的分类系统中进行分类。这样用户就有可能在他的查询结果中进行探索和导航。该系统提供了一种灵活的方式，通过向下钻取分层结构类别来细化查询。用户可以使用所谓的列表浏览器在一个类别中浏览结果，也可以使用所谓的矩阵浏览器同时在两个类别中浏览结果(Ziegler et al. 2002)。一个熟悉且众所周知的交互式树小部件用于表示类别和定位的超链接，因此系统的处理非常直观。

This paper describes New Zealand E-government activities supporting the discovery of services through the use of Dublin Core-based New Zealand Government Locator Service (NZGLS) metadata. It notes the issues faced in collecting service metadata from agencies to populate a new whole-of-government portal. The paper then considers the adequacy of the metadata schema for service description, and identifies a difficulty in applying definitions which refer to the content of the resource to a process-like resource such as a service. Three approaches to this challenge are suggested: creating a surrogate description to provide a source of content; treating the information exchanged in conducting the service as the content; and using additional contextual metadata. The adequacy of the schema for covering all the users' needs for discovering and using a service is examined, and the need for metadata about specific service delivery points and conditions is noted. Finally, it is observed that future stages of e-government will require more sophisticated descriptions of services to support processes beyond discovery.

This paper presents our ongoing work in establishing a multilingual domain ontology for a biosecurity portal. As a prototypical approach, this project is embedded into the bigger context of the Agricultural Ontology Service (AOS) project of the Food and Agriculture Organization (FAO) of the UN. The AOS will act as a reference tool for ontology creation assistance and herewith enable the transfer of the agricultural domain towards the Semantic Web. The paper focuses on introducing a comprehensive, reusable framework for the process of semi-automatically supported ontology evolvement, which aims to be used in follow-up projects and can eventually be applied to any other domain. Within the multinational context of the FAO, multilingual aspects play a crucial role and therefore an extendable layered ontology modelling approach will be described within the framework. The paper will present the project milestones achieved so far: the creation of a core ontology, the semiautomatic extension of this ontology using a heuristic toolset, and the representation of the resulting ontology in a multilingual web portal. The reader will be provided with a practical example for the creation of a specific domain ontology, which can be applied to any possible domain. Future projects, including automatic text classification, and ontology facilitated search opportunities, will be addressed at the end of the paper.

Accessibility metadata is simply metadata that describes the accessibility of resources and services, usually those on, or available through, the web. Awareness of widespread web content inaccessibility led to work being done to develop guidelines for authors and others to make sure that content would be more accessible to those with special access needs, especially those with disabilities who were being disenfranchised by their lack of access to the web. Currently, work is being done to find ways of signalling the degree of accessibility of resources, and ways of matching resources to searches and people. In addition, accessibility metadata could be used to repair some inaccessibility problems on the fly. This paper describes some of the work being done and the problems that have contributed to make the progress comparatively slow.
