CSIRO stands for Commonwealth Scientific and Industrial Research Organization. It is the Australian Government’s main research body. This is the first year CSIRO is taking part in TREC. We got involved in textual information retrieval research as a part of our activities in Resource Discovery Unit at the Research Data Network Co-operative Research Centre. The primary aim of our research in IR i...

Content based retrieval from distributed libraries raises new and challenging issues with respect to retrieval from a single repository. In particular, an effective management of distributed libraries develops upon three main processes: resource description (extraction of descriptors that qualify the content of a given archive), resource selection (given a user query, select the resources that ...

The mobility characteristic brings new challenges for research of P2P computing over the wireless mobile networking environment. Peers’ movements in wireless mobile network change the routing path which affects the file retrieval performance. Thus, how to improve the resource discovery and retrieval for P2P file sharing applications in wireless mobile networks becomes a critical issue. In this ...

Browsing the web involves two main tasks: finding the right web page and then making sense of its content. A significant amount of research has gone into supporting the task of finding web resources through ‘standard’ information retrieval mechanisms, or semantics-enhanced search. Much less attention has been paid to the second problem. In this paper we describe Magpie, a tool which supports th...

In the latest years, the offering of Enterprise Resource Planning systems (ERPs) started to target in part the Public Administrations (PA's) and, above all, the Small / Medium Enterprises (SMEs), both by software multinational corporations and by local software houses. The introduction of ERPs into SMEs cannot be based on a sheer reproduction of the experiences with larger companies and represe...

The seeking of teaching resources on the web is a very common practice among instructors. Some on-line systems aim to support instructors in this complex and delicate task. In fact, quality of teaching is without doubt an important factor for learning, and an important aspect of teaching is the delivery of quality learning material to students. Remarkable results have been achieved in the reuse...

When searching multiple sources of information it is crucial to select only relevant sources for a given query, thus filtering out nonrelevant content. This task is known as resource selection and is used in many areas of information retrieval such as federated and aggregated search, blog distillation, etc. Resource selection often operates with limited and incomplete data and, therefore, is as...

This paper examines the problem of Internet resource discovery from the point of view of Information retrieval. It firstly discusses the traditional Information Retrieval task, and then considers current approaches to Internet Information Retrieval. These approaches give rise to problems such as Information Burial, which are defined and discussed. Finally, a model is proposed that partially cir...

An open problem for Distributed Information Retrieval is how to represent large document repositories (known as resources) efficiently. To facilitate resource selection, estimated descriptions of each resource are required, especially when faced with non-cooperative distributed environments[1]. Accurate and efficient Resource description estimation is required as this can have an affect on reso...

This paper adopts Hadoop to build and test the storage retrieval platform for painting resources. as MapReduce computing framework uses Distributed Filesystem (HDFS) distributed file system store massive log data, which solves problem of data. According business requirements system, this designs according process web text mining, mainly divided into data preprocessing module, analysis visualiza...
