Development and Application of Techniques for Detecting Equivalent Documents. The web is a vast collection of data, such as text and images, but contains large numbers of duplicates - the same document or picture may be present many times. Even personal collections of information, such as the documents and digital photos people keep on their home computers, often have many versions of the same item. However, detecting such duplicates is not straightforward, as they may have been edited, or may, ....Development and Application of Techniques for Detecting Equivalent Documents. The web is a vast collection of data, such as text and images, but contains large numbers of duplicates - the same document or picture may be present many times. Even personal collections of information, such as the documents and digital photos people keep on their home computers, often have many versions of the same item. However, detecting such duplicates is not straightforward, as they may have been edited, or may, for example, be shown in different forms; for example, the quality of a photo may be reduced for display on a mobile phone. In this project we plan to detect such duplicates, and use the results to improve search and management of data.Read moreRead less
Efficient and Effective Interactive Visualization of Large Graphical Information Spaces. The expected outcome will change ways of interacting with and thinking about information processing for all information systems. As Australian companies became larger and more global, the ability to view and analyse the growing amount of company information becomes crucial to aspects as varied as trouble shooting or new ventures and eventually to the very viability of the organization itself. The expected ou ....Efficient and Effective Interactive Visualization of Large Graphical Information Spaces. The expected outcome will change ways of interacting with and thinking about information processing for all information systems. As Australian companies became larger and more global, the ability to view and analyse the growing amount of company information becomes crucial to aspects as varied as trouble shooting or new ventures and eventually to the very viability of the organization itself. The expected outcome will enhance this ability by providing an optimised global view and an effective navigation scheme of large graphical information spaces. This will attract leading international IT companies to use it for developing cutting-age tools, and will enhance significantly the capacity and international standing of Australian IT industry.Read moreRead less

Components for Active Knowledge Portals. Businesses require people to collaborate and share knowledge in their work processes especially when they are in different locations. Such collaboration emerges by dynamically creating parallel and disconnected collaborative tasks that must be coordinated to meet organizational goals. This project will define the semantics of such emerging processes in the context of software digital workspaces that support them. It will then identify ways of constructing ....Components for Active Knowledge Portals. Businesses require people to collaborate and share knowledge in their work processes especially when they are in different locations. Such collaboration emerges by dynamically creating parallel and disconnected collaborative tasks that must be coordinated to meet organizational goals. This project will define the semantics of such emerging processes in the context of software digital workspaces that support them. It will then identify ways of constructing and using workspaces by creating active knowledge portals to support emerging processes. These portals will include software agents that are sensitive to the business context and help coordinate tasks within the emerging process.Read moreRead less

Dynamic Index Maintenance for Text Search Engines. Text retrieval systems such as internet search engines use high-performance indexes to rapidly locate documents that match user queries. In recent years there have been major improvements in query evaluation and index construction techniques. As the data changes, it is necessary to keep the index up to date, but current methods for maintaining indexes are slow and costly. The aim of this project is to develop methods that provide on-the-fly u ....Dynamic Index Maintenance for Text Search Engines. Text retrieval systems such as internet search engines use high-performance indexes to rapidly locate documents that match user queries. In recent years there have been major improvements in query evaluation and index construction techniques. As the data changes, it is necessary to keep the index up to date, but current methods for maintaining indexes are slow and costly. The aim of this project is to develop methods that provide on-the-fly update at much lower cost, thereby improving the performance of text retrieval systems. This work involves both practical development and innovation in fundamental algorithms.Read moreRead less
