Existing systems require the user either to add new data manually to a collection, or to have programming knowledge in order to use existing application programming interfaces (APIs) in order to automate scheduled collection updates. We incorporate a scheduling module into the Greenstone digital library software, which allows the user to set up scheduled and automated building of a collection at periodic intervals. This module interacts with the task scheduler on the host platform, such as Linux. Windows and Mac OS X, thereby making it a simple yet powerful tool for scheduled collection maintenance.","PeriodicalId":198626,"journal":{"name":"2007 2nd International Conference on Digital Information Management","volume":"738 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131762585","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We argue that the social aspect, which is missing from today’s peer-to-peer (p2p) systems, should be seen both as a goal and a means for self-organized virtual communities to be built and fostered. Hence, we propose that the ongoing research efforts for designing effective incentive mechanisms in p2p systems, based on principles from game theory, should be directed towards a more sociological/psychological approach. We also provide some possible first steps towards this direction.","PeriodicalId":198626,"journal":{"name":"2007 2nd International Conference on Digital Information Management","volume":"37 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131560457","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We propose a novel model that considers the user's interests as sources of evidence in order to tune the accuracy of documents returned in response to the user query. The model's fundation comes from influence diagrams which are extension of Bayesian graphs, dedicated to decision-making problems. Hence, query evaluation is carried out as an inference process that aims to computing an aggregated utility of a document by considering its relevance to the query but also the corresponding utility with regard to the user's topics of interest. Experimental results using enhanced TREC collections indicate that our personalized retrieval model is effective.","PeriodicalId":198626,"journal":{"name":"2007 2nd International Conference on Digital Information Management","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134314041","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This work presents the development, implementation and application of an adaptive apriori algorithm for mining large datasets focusing on extracting interesting associations rules for less frequent item sets. The relevance of the adaptive apriori algorithm has been studied with respect to the set of data that was obtained by applying the transitive closure property among objects obtained from the biomedical scientific literature where both frequent and infrequent events need to be detected. Three adaptive apriori association rule mining methods, the weight induced apriori association rule mining (WIAARM), weight and significance induced apriori association rule mining (WSIAARM) and significance induced apriori association rule mining (SIAARM) are presented to effectively prune and extract meaningful association rules. These rules were applied on a large set of biological entity-entity association records and the results indicated that both WIAARM and WSIAARM were able to discover item sets with low and high frequency.","PeriodicalId":198626,"journal":{"name":"2007 2nd International Conference on Digital Information Management","volume":"51 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116526935","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this paper, the behavior of the TCP Congestion Window is observed and the performance of the system is evaluated when iSCSI access through multiple connections is performed using a multi-routing function of a VPN router. Furthermore, we have examined the iSCSI access method with mutiple connections on VPN when a parallel storage system is used as Target of network storage.","PeriodicalId":198626,"journal":{"name":"2007 2nd International Conference on Digital Information Management","volume":"90 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125002330","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

When performing query processing on large scale XML data, XML storage schemes on secondary storage and their access methods greatly affect the entire performance. For this reason, we developed an XQuery processing scheme in which an XML document is internally represented as a set of DTM blocks and can be directly stored on secondary storage. Our scheme is tailored for read-oriented workloads, and an XML document is stored on disks as arrays of nodes. We analyzed the actual data access patterns to DTM appeared in processing XML queries, and employed the combination of informed prefetching and scan-resistant buffer management based on the analysis. Our experimental results showed that our storage scheme outperforms competing schemes with respect to I/O-intensive workloads, and our sophisticated prefetching and caching increase overall throughput without significant drawbacks.","PeriodicalId":198626,"journal":{"name":"2007 2nd International Conference on Digital Information Management","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122047773","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Many third level institutions utilise thin client and remote access protocols, and as the use of portable storage devices continues to increase, there is a strong case for the development of such a tool. Several existing thin client implementations lack the ability' to manipulate client side file systems when working on the server side, and consequently restrict users productivity. By modifying the existing thin client computing model and creating a supplemental package for existing thin client protocols, we can eliminate these barriers, and support redirection of local peripheral devices from the client to the server. While existing support for local peripheral redirection is often platform or protocol dependent, our approach is independent of either. Moreover, we demonstrate that our approach improves on existing implementations in certain aspects of performance.","PeriodicalId":198626,"journal":{"name":"2007 2nd International Conference on Digital Information Management","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129107910","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
