In this paper, we focus on a relatively new approach whose foundations rely on the works of A. Kolmogorov. The main idea is to give a formal meaning to \"information content\" and to use it to measure in some sense the deviation with regard to standard behaviour. We apply this kind of method to delect spam email, which is a well-known disease for mail client. To validate our approach, we have implemented a k-nearest neighbors algorithm which could easily become a plug-in for an open source mail client. Despite its strong theoretical basis, Kolmogorov's works give rise to very simple practical applications, easy to implement and with surprisingly accurate results.","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":"130538537","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}

A decrease in the learning accuracy likely reduces the context prediction quality. We study the impact of context pre-processing on the learning efficiency of context prediction schemes.

These e-Labs enable learners to train on remote real or virtual systems. They represent essential components in e-learning environments, especially in scientific and technical disciplines. In this context, AIP-Primeca RAO is a pool of resources and competencies for industrial topics for many universities in Rhone. Due to the constraints of using heavy and shared resources, AIP is setting up new laboratories related to automation as both local and distant resources.

However, these applications suffer from the unavailability of underlying data sources. In the presence of unavailable data sources, various techniques exist. Worst solutions simply ignore the problem, or generate an error, which is relatively frustrating for the user. Other works consider partial answers or mutant query plans to delay the querying of unavailable sources. Despite of their efficiency, those works are not order sensitive. It means that the data order in the final result does not reflect the underlying data source order and the order defined by the query. In this paper, we propose an order sensitive approach for the evaluation of queries when data sources are unavailable.","PeriodicalId":198626,"journal":{"name":"2007 2nd International Conference on Digital Information Management","volume":"34 4","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114022424","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}

On one hand we explain important rules to be followed during the design of the information system itself, e.g. the data supply process. On the other hand we introduce different categories for potential geographic web services and analyze these categories according to several properties. From some of those properties rules can be extracted on how well every kind of service is suited for commercial use and which technical context (e.g. security) has to be observed to be able to offer it. The whole article is based on a case study and prototype where we implemented a geographic database and geographic web services from each of the different categories in the domain of hydrology.","PeriodicalId":198626,"journal":{"name":"2007 2nd International Conference on Digital Information Management","volume":"15 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":"115362349","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}

A data integration system provides a unified view for users to submit queries over multiple autonomous data sources. The queries are processed over a global schema that offers an integrated view of the data sources. Much work has been done on query processing and choosing plans under cost criteria. However, not so much is known about incorporating information quality analysis into data integration systems, particularly in the integrated schema. In this work we present an approach of information quality analysis of schemas in data integration environments. We discuss the evaluation of schema quality focusing in the minimality aspect and define some schema transformations to be applied in order to improve schema design.","PeriodicalId":198626,"journal":{"name":"2007 2nd International Conference on Digital Information Management","volume":"68 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":"124942049","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}

Veltman","doi":"10.1109/ICDIM.2007.4444246","DOIUrl":"https://doi.org/10.1109/ICDIM.2007.4444246","url":null,"abstract":"Providing solutions to problems associated with methodical creation, management and information search in an annotation archive is the core of this study. Information archives grow at a relatively slow space but annotations associated with archives grow geometrically because of the diversity of reflections on documents emanating from different authors and with time. Information annotation by users of document is generally connected to a definite document, specific individuals or a precise time. Annotation can be seen as an informal way for individuals who do not freely have initial rights for a document to \"publish\" their thoughts on a subject of interest. Publishing one's thoughts using annotations does not involve publication protocols such as copyright issues. Where there is freedom of expression through annotation, the flexibility and frequencies of \"publishing\" one's views on a subject are bound to increase. This flexibility and simplicity in expression entails a systematic management of an annotation archive. The creation of an annotation database is often seen as the human activity that can embed the function of its creator (who is also a document user), the original document and time. It means that a database of annotations based on three parameters (creator, document and time) may include divergent annotations as a result of multiple documents and human factors. With participation of diverse users, there can be divergent interpretations of subjects of interest based on varying thoughts of users. With change of time, a user's opinion on a subject can change. The question that quickly comes to mind is how can a database growing geometrically, with divergent reflections (annotations), by divergent users with considerable length of time be created and searched effectively in a collaborative environment? We consider creation and the exploration of an annotation database by combining the concept of semantic technology with the topic maps data model. Each word used by users in annotation creation benefits from the potential of semantic technology based on topic maps to resolve the difficulty in management. More precisely, our attention in this study is the creation and exploitation of annotation databases to improve information research. Our TMSUMS platform benefits of combining the SUMS-based semantic logical model with the topic maps-based semantic physical data model. As one of the key issues, we brought to light, the problem related to annotation creation in a collaborative environment. Thereafter, we introduce scenarios of information search in an annotation database constructed on specific parameters. We demonstrate how difficult it to search for meaningful information from such an annotation archive/database in a normal situation. Our proposal is a search through such a database with the concepts of semantic technology and topic maps data model to demonstrate how such a search can be improved.
