Reading web pages, news, articles, manuals and users' guides and getting the gist of a test are some of the examples for our daily need to translation. This paper introduces a Persian to English machine translation system, named PEnT2. It uses a transfer based approach and employs the grammatical role of the sentence words as the main clue to perform the translation processes. PEnT2 translates simple Persian sentences into English using a hybrid approach. It exploits the advantages of rule based, knowledge based and corpus based methods in different components of a machine translation system including word sense disambiguation, structural transfer and structure optimization. Experiments show improved results in comparison with other available systems.","PeriodicalId":300287,"journal":{"name":"2009 Fourth International Conference on Digital Information Management","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-12-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122587552","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}

The main problem of text mining is the large amount of zero account in the matrix representation. Recently a document visualization technique incorporating the Zero Inflated Poisson model in the Generative Topographic Mapping algorithm has been proposed. This probabilistic model can be applied as a text document visualization tool. In this work, an algorithm for automatically extracting the clusters in the visualization results is presented. The combination of visualization-cluster extraction algorithms allows to obtain and evaluate document collections. Several results are presented for 20-Newsgroups and Reuters data.","PeriodicalId":300287,"journal":{"name":"2009 Fourth International Conference on Digital Information Management","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-12-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121173484","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}

The normal is sampled in proportion to each polygon's area and then it is calculated by weight average method via angles and interpolated.

Here the development of such product customization requires the adoption of innovative agile manufacturing techniques. To date this innovation has focused on the improved process development between the different stages of manufacturing Product Lifecycle Management (PLM). However in terms of implementing the application, data management techniques have lagged behind often leaving these processes disjointed and lacking in automation. This paper proposes an improved model based on innovation in the manufacturing PLM. Building on existing work in the use of ontologies for knowledge management, the paper applies these techniques to PLM. The implementation has been applied to develop a case study around a Ford production line. The prototype presents an innovative approach to PLM and tested using a state of the art Web Service infrastructure implemented on a Ford Powertrain test rig.","PeriodicalId":300287,"journal":{"name":"2009 Fourth International Conference on Digital Information Management","volume":"85 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-12-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127859964","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 BBS consists of a number of discussion boards, each of which focuses on a particular subject. A discussion on a topic consists of a seed articles followed by some articles responsive to the seed article or other responsive articles. This paper investigates the social community analysis technique to discover the political tendency of users within the boards from discussions. We first extract the social interactions between users, such as \"reply\" and \"advocate\" of posts between users. A social network among users is constructed based on the extracted social interaction. After building the social network, we employ the graph partition, graph coloring, and graph clustering algorithms respectively to discover the social communities. Users of the same community have more potential of political opinion agreement with each other. By using this approach, we are able to partition users into two opposite groups and identify their political tendency effectively without linguistic analysis of discussion content.","PeriodicalId":300287,"journal":{"name":"2009 Fourth International Conference on Digital Information Management","volume":"98 6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-12-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128003259","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, the stringent energy constraints place a hurdle to the continuous functioning of the sensing devices. Clustering a network leads to a lesser number of nodes participating in active transmissions. Data aggregation reduces redundant packet sending. Given that transmission is the primary energy consuming activity for a sensor mote, this paper exploits the joint advantages of clustering and data aggregation in decreasing communication cost. A data centric analysis was performed to justify the use of data aggregation. Experimental results on a realistic platform with MICAz motes running TinyOS embedded system showed 22% energy savings and 13% overhead reduction, confirming the attractive advantages of data aggregation and clustering such as more efficient transmissions.","PeriodicalId":300287,"journal":{"name":"2009 Fourth International Conference on Digital Information Management","volume":"86 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-12-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124953373","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}

It is because the minimum support, the most popular statistical significance measurement, is not capable of reflecting the domain user's interest. This paper presents visual frequent itemset mining (VFIM) as an alternative to the traditional apriori-like frequent itemset mining. VFIM pushes the domain user's cognitive power into the data mining process. To this end, a formal visual data mining model is proposed and a prototype of the model is created. The effectiveness of the proposed model is demonstrated by showing that VFIM generates frequent patterns, by means of user interaction, that are compatible with those generated by traditional apriori-like algorithms without executing them.","PeriodicalId":300287,"journal":{"name":"2009 Fourth International Conference on Digital Information Management","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-12-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128860168","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 consider a schema mapping process in the OO→XML direction based on a detailed analysis of the OO database model concepts. A prototype tool was implemented to validate the process.
