Dynamic Load Balancing for Systems under Heavy Traffic Demand and High Task Size Variation. Current computer systems cannot cope with extremely heavy traffic demands. A solution to such a difficult problem is to dynamically balance the load across the system's servers. Several solutions have been proposed and demonstrate advances in certain limited conditions (e.g. uniform distribution). However fundamental research work must be undertaken beyond the current way of dealing with the core issues o ....Dynamic Load Balancing for Systems under Heavy Traffic Demand and High Task Size Variation. Current computer systems cannot cope with extremely heavy traffic demands. A solution to such a difficult problem is to dynamically balance the load across the system's servers. Several solutions have been proposed and demonstrate advances in certain limited conditions (e.g. uniform distribution). However fundamental research work must be undertaken beyond the current way of dealing with the core issues of load balancing. Accounting for realistic conditions is a theoretical and practical challenge. This project aims at developing theoretical and computational models for dynamic task distribution for the studied systems. The benefits include substantial improvement of the system response time.Read moreRead less

Summary
The EarthByte software and database system. Earth processes over geological timescales cannot be understood outside of a plate tectonic context. However, no standard tool exists to explore the causes and effects of lithosphere-mantle interaction in accordance with past plate configurations. Our aim is to develop a Palaeo-Geographic Information System called EarthByte that will connect the open source and architecture-independent GPlates and GMT software, and implement XML-based service interfac ....The EarthByte software and database system. Earth processes over geological timescales cannot be understood outside of a plate tectonic context. However, no standard tool exists to explore the causes and effects of lithosphere-mantle interaction in accordance with past plate configurations. Our aim is to develop a Palaeo-Geographic Information System called EarthByte that will connect the open source and architecture-independent GPlates and GMT software, and implement XML-based service interfaces and databases. EarthByte will create the foundation for an e-geoscience framework for grid-based data access and Earth process modelling by linking geological and geophysical observations to palaeogeographic models for constraining mantle convection and lithospheric deformation.Read moreRead less

Linguists will be able to harness the power of natural language processing techniques for their study of the world's languages. A demonstration system will be developed, permitting linguists to locate examples of syntactic constructions in a large database of parsed text, and to explore similarities across different languages. The project will also encompass a selection of minority languages for which only a small amount of data is available.Read moreRead less
Using Past Queries for Fast and Accurate Web Searching. Searching the entire Internet, or a company web site, has become a vital task for modern organisations. While there has been significant research into improving search engines through using web pages themselves, very little attention has been paid to improving web search by exploiting the vast numbers of queries that users submit to search engines each day. This project will use state of the art compression and algorithmic techniques to imp ....Using Past Queries for Fast and Accurate Web Searching. Searching the entire Internet, or a company web site, has become a vital task for modern organisations. While there has been significant research into improving search engines through using web pages themselves, very little attention has been paid to improving web search by exploiting the vast numbers of queries that users submit to search engines each day. This project will use state of the art compression and algorithmic techniques to improve the speed and accuracy of web search using data gleaned from millions of Internet queries (provided under agreement by Microsoft). Improving search engines will have a direct benefit to many Australian industries, and support the government's priority area of "smart information use".Read moreRead less

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
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.

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
