A challenge to this issue is to substitute an unsupported access point with others, so that the most similar semantics to the original access point can be obtained. In this paper, we describe the Bib-1 access points semantics of the Z39.50 protocol using the RDF Schema language, based on the official semantics specification of the Z39.50 Bib-1 attribute set. Moreover, we suggest two algorithms for the substitution of unsupported access point exploiting semantics information from the RDFS graph. The algorithms produce the set of access points, the proper combination of which produces semantics similar to the original access point. Then, we optimize the resulting set of access points by producing the minimal set of them with the closest semantics to the original one. Finally, we present an implementation where Z39.50 searches could be done using our access point substitution algorithms.","PeriodicalId":198626,"journal":{"name":"2007 2nd International Conference on Digital Information Management","volume":"35 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":"126929525","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}

Given the limited bandwidth between replicas, these systems suffer from long repair times after a hard disk crash, making them vulnerable to data loss when several replicas fail within a short period of time. Recent work has suggested that the probability of data loss can be predicted by modeling the number of live replicas using a Markov chain. This, in turn, can then be used to determine the number of replicas necessary to keep the loss probability under a given desired value. Previous authors have suggested that the model parameters can be estimated using an expression that is constant or linear on the number of replicas. Our simulations, however, show that neither is correct, as these parameter values grow sublinearly with the number of replicas. Moreover, we show that using a linear expression will result in the probability of data loss being underestimated, while the constant expression will produce a significant overestimation. Finally, we provide an empirical expression that yields a good approximation of the sublinear parameter values. Our work can be viewed as a first step towards finding more accurate models to predict the durability of this type of systems.","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":"121746305","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}

Several applications in the context of information systems are based on its use: electronic publishing, technical documentation, digital libraries, web, etc. An XML document is mainly hierarchical. But, in some applications, several concurrent hierarchical structures could be associated to the same textual data. This paper presents an XML environment dedicated to the representation and the querying of such documents that we call multistructured textual documents. Our work aims at proposing a method for a compact representation of multiple trees over a single text based on segmentation. Segmentation encoding allows querying overlap/containment relations of markups belonging to different structures. This paper particularly focuses on the architecture of the XML environment implementing our proposals.","PeriodicalId":198626,"journal":{"name":"2007 2nd International Conference on Digital Information Management","volume":"38 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":"115839867","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}

Several key pre-distribution schemes have been proposed for use in PANs. but these schemes only support key management within a PAN. In a ubiquitous environment, however, users with multiple personal wireless devices are likely to form mobile ad hoc networks, requiring key management between PANs. Moreover, PANs cannot rely on the universal accessibility of an online TTP, and PAN users are unlikely to delegate security operations to an external trusted party for privacy reasons. We thus propose a provably secure self-organising key pre-distribution scheme for use both within and between PANs.","PeriodicalId":198626,"journal":{"name":"2007 2nd International Conference on Digital Information Management","volume":"48 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":"124600740","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}

However, extracting such bibliographic data from printed documents requires human intervention; it is therefore not cost-effective, even using various document image-processing techniques such as optical character recognition (OCR). In this paper, we describe an automatic authors' names extraction method for academic articles scanned with OCR mark-up. The proposed method first extracts authors' blocks, which include assumed author/delimiter characters based on layout analysis, and then uses a specifically designed hidden Markov model (HMM) for labeling the unsegmented character strings in the block as those of either an author or a delimiter. We applied the proposed method to Japanese academic articles. Results of these experiments showed that the proposed method correctly extracted more than 99%, of authors' blocks with manual tuning; the proposed HMM correctly labeled more than 95% of the author name strings.","PeriodicalId":198626,"journal":{"name":"2007 2nd International Conference on Digital Information Management","volume":"57 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":"132554857","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}
