BlogForever D2.6: Data Extraction Methodology

This report outlines an inquiry into the area of web data extraction, conducted within the context of blog preservation. The report reviews theoretical advances and practical developments for implementing data extraction. The inquiry is extended through an experiment that demonstrates the effectiveness and feasibility of implementing some of the suggested approaches. More specifically, the report discusses an approach based on unsupervised machine learning that employs the RSS feeds and HTML representations of blogs. It outlines the possibilities of extracting semantics available in blogs and demonstrates the benefits of exploiting available standards such as microformats and microdata. The report proceeds to propose a methodology for extracting and processing blog data to further inform the design and development of the BlogForever platform

Towards E-Government 2.0: An Assessment of Where E-Government 2.0 Is and Where It Is Headed

The aim of electronic government (e-government) is to increase the convenience and accessibility of government services and information. E-government's past emphasized the automation of routine government operations. Modern e-government centers on Web-based delivery of information and services. As the Internet moves away from version 1.0, the author examines the literature for evidence and best practices on the adoption and use to date of Web 2.0 technologies in government. Despite evidence that Web 2.0 technologies have the potential to enhance knowledge management and citizen engagement, there remains a weak body of evidence on its adoption and usage. The essay explores the early evidence and suggests a path towards realization of the promise that e-government 2.0 holds. The path involves support and collaboration from a diverse set of stakeholders to study the impact of, as well as develop best practices for, using Web 2.0 technologies to improve government services and public administration

Automatic Extraction and Assessment of Entities from the Web

The search for information about entities, such as people or movies, plays an increasingly important role on the Web. This information is still scattered across many Web pages, making it more time consuming for a user to find all relevant information about an entity. This thesis describes techniques to extract entities and information about these entities from the Web, such as facts, opinions, questions and answers, interactive multimedia objects, and events. The findings of this thesis are that it is possible to create a large knowledge base automatically using a manually-crafted ontology. The precision of the extracted information was found to be between 75–90 % (facts and entities respectively) after using assessment algorithms. The algorithms from this thesis can be used to create such a knowledge base, which can be used in various research fields, such as question answering, named entity recognition, and information retrieval

Cultural institutions and Web 2.0

This report gives the results of an exploratory survey of the approaches that Australian cultural institutions are implementing to meet Web 2.0 challenges. For the purpose of this study cultural institutions are those organizations open to the general public that house information artefacts representative of national culture, namely galleries, museums, libraries and archives. The aim was to undertake a brief survey of the strategies being implemented by Australian cultural institutions to come to terms with Web 2.0 development, and meet challenges. This has been complemented by some consideration of management and technical issues that have been reported in the literature. The work leads to some findings that should inform both the institutions and the Australian research and development community of issues and opportunities relating to enhanced provision of access to Australian cultural heritage

The genesis and emergence of Web 3.0: a study in the integration of artificial intelligence and the semantic web in knowledge creation

The web as we know it has evolved rapidly over the last decade. We have gone from a phase of rapid growth as seen with the dot.com boom where business was king to the current web 2.0 phase where social networking, Wiki’s, Blogs and other related tools flood the bandwidth of the world wide web. The empowerment of the web user with web 2.0 technologies has led to the exponential growth of data, information and knowledge on the web. With this rapid change, there is a need to logically categorise this information and knowledge so it can be fully utilised by all. It can be argued that the power of the knowledge held on the web is not fully exposed under its current structure and to improve this we need to explore the foundations of the web. This dissertation will explore the evolution of the web from its early days to the present day. It will examine the way web content is stored and discuss the new semantic technologies now available to represent this content. The research aims to demonstrate the possibilities of efficient knowledge extraction from a knowledge portal such as a Wiki or SharePoint portal using these semantic technologies. This generation of dynamic knowledge content within a limited domain will attempt to demonstrate the benefits of semantic web to the knowledge age
