Topic distillation via sub-site retrieval

Topic distillation is one of the main information needs when users search the Web. Previous approaches for topic distillation treat single page as the basic searching unit, which has not fully utilized the structure information of the Web. In this paper, we propose a novel concept for topic distillation, named sub-site retrieval, in which the basic searching unit is sub-site instead of single page. A sub-site is the subset of a website, consisting of a structural collection of pages. The key of sub-site retrieval includes (1) extracting effective features for the representation of a sub-site using both the content and structure information, (2) delivering the sub-site-based retrieval results with a friendly and informative user interface. For the first point, we propose Punished Integration algorithm, which is based on the modeling of the growth of websites. For the second point, we design a user interface to better illustrate the search results of sub-site retrieval. Testing on the topic distillation task of TREC 2003 and 2004, sub-site retrieval leads to significant improvement of retrieval performance over the previous methods based on single pages. Furthermore, time complexity analysis shows that sub-site retrieval can be integrated into the index component of search engines.

Using government websites to enhance democratic E-governance: A conceptual model for evaluation

The last few decades have witnessed unprecedented transformations in every sector of society, resulting from the explosive advancement of information and communication technologies. This drastic development has raised the hopes of citizens for better lives, in both developing and advanced countries, urging innovation in government to make it more competent. Due to e-business revolutions, governments around the world have applied similar principles and technologies to government by opening their websites for more efficient publication of information and more effective delivery of public services. While a government website is an important venue for citizens to participate in public affairs and decision-making processes, early e-government practices tended to overlook democratic purposes by focusing on the features of e-business and information systems. There have been increasing criticisms that e-government system design has focused mainly on the provider's perspectives. Reflecting on the theoretical implications of this, we argue that a government website should facilitate democratic processes involving not only information sharing and delivery of better public services, but also deliberation and coproduction. The purpose of this study is to probe into multidimensional features that enable government websites to fulfill their promises. Developing an integrative model for evaluating a government website, namely the Democratic E-governance Website Evaluation Model, we conducted a qualitative meta-analysis of four strands of literature: information systems, business, public administration, and democratic theory. Our study contributes to the literature by extending the purview of e-government website analysis beyond the question of citizens' acceptance and towards the issue of their engagement, bringing a stimulating view of citizens as active agents in governance, and it provides a holistic model for public authorities to improve their websites to facilitate democratic e-governance that helps to create more effective public outcomes.
