Realcourse is a cooperative Internet video publishing and delivery system used by more than thirty Chinese universities to share course videos. The design of Realcourse bears the following assumptions 1) the system is supposed to consists of hundreds of unreliable but controllable servers where temporal failures are common, permanent failures are rare, 2) videos are concurrently uploaded to local servers but their metadata are broadcasted to all servers, 3) users are connected to and served by local servers but should be able to watch all the videos in the system in a seamless and efficient fashion. Realcourse has gone through two versions. In Realcourse1.0, all servers were treated equal and fully connected by messaging channels. In order to maintain a consistent global directory among servers, each server informs all others of local update operations through the message channels. The fully connected server topology poses a great challenge to system management with respect to failures. To solve this problem, Realcourse2.0 adopts a server topology of multiple overlapping stars by 1) replacing direct broadcast with relayed-broadcast, in which message is first sent to a relay server and then forwarded to all other servers, 2) partitioning the global directory into sub-trees, each sub-tree is then fully replicated to a group of selected servers while groups may overlap with each other. This paper explains why such a change is necessary and how it was done. Realcourse has been operational since December 2003. Today, more than 5000 videos are served. We constantly observe about 10000 unique user IP addresses each day.","PeriodicalId":212445,"journal":{"name":"2009 Fourth ChinaGrid Annual Conference","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-08-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132038048","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 comprises TCM ontology and TCM Databases as data resources and Dart Search, Dart Query etc. as TCM application. This paper reports an ontology engineering component of the TCM Semantic Grid. Although ontology engineering has gained significant progress, ontology construction still mainly depends on manual work and tends to be mistaken prone. In this paper, we introduce a semantic relation verification method based on both domain ontology and domain publications. A modified vector space model is used to extract semantic relations from domain publications, which is particularly useful when the semantic relation cannot be extracted directly. Association rule learning method is used to distinguish significant relations from trivial ones. Further verification method is used to give user recommendations of relation types. We use Traditional Chinese Medicine Language System, domain ontology for Traditional Chinese Medicine, and relevant publications to validate our approach. But our method is not limited to this field. In fact, any data source that can be extracted into relevant instance pairs is applicable.","PeriodicalId":212445,"journal":{"name":"2009 Fourth ChinaGrid Annual Conference","volume":"66 2","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-08-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"120924702","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}
