MARK-OPT marks the lowest structure-modification-operation (SMO) occurrence point during optimistic latch coupling operations, to reduce the cost of SMO compared to the conventional protocols such as ARIES/IM and INC-OPT. The marking reduces the frequency of restarts for spreading the range of X latches, which will clearly improves the system throughput. Moreover, the MARK-OPT is deadlock free and satis- fies the physical consistency requirement for Btrees. These indicate that the MARK-OPT is right and suitable as a concurrency control protocol for Btree structures. This paper also proposes three variations of the protocol, INC-MARKOPT, 2P-INT-MARK-OPT and 2P-REP-MARK-OPT, by focusing on tree structure changes from other transactions. We implement the proposed protocols, the INC-OPT, and the ARIES/IM for the Fat-Btree, a form of parallel Btree, and compare the performance of these protocols using a large-scale blade system. The experimental results indicate that the proposed protocols always improve the system throughput, and the 2P-REP-MARK-OPT is the most useful protocol in a high update environment. Moreover, in the experiment, the low frequency of restarts in the proposed protocols indicates that the marking in the proposed protocols is effective.","PeriodicalId":331953,"journal":{"name":"22nd International Conference on Data Engineering Workshops (ICDEW'06)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2006-04-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131972671","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}

Weikum","doi":"10.1109/ICDEW.2006.110","DOIUrl":"https://doi.org/10.1109/ICDEW.2006.110","url":null,"abstract":"A compelling application of peer-to-peer (P2P) system technology would be distributed Web search, where each peer autonomously runs a search engine on a personalized local corpus (e.g., built from a thematically focused Web crawl) and peers collaborate by routing queries to remote peers that can contribute many or particularly good results for these specific queries. Such systems typically rely on a decentralized directory, e.g., built on top of a distributed hash table (DHT), that holds compact, aggregated statistical metadata about the peers which is used to identify promising peers for a particular query. To support an a-priori unlimited number of peers, it is crucial to keep the load on the distributed directory low. Moreover, each peer should ideally tailor its postings to the directory to reflect its particular strengths, such as rich information about specialized topics that no or only few other peers would also cover. This paper addresses this problem by proposing strategies for peers that identify suitable subsets of the most beneficial statistical metadata. We argue that posting a carefully selected subset of metadata can achieve almost the same result quality as a complete metadata directory, for only the most relevant peers are eventually involved in the execution of a given query. Additionally, asking only relevant peers will result in higher precision, as the noise introduced by poor peers is reduced. We have implemented these strategies in our fully operational P2P Web search prototype Minerva, and present experimental results on real-world Web data that show the viability of the strategies and their gains in terms of high search result quality at low networking costs.","PeriodicalId":331953,"journal":{"name":"22nd International Conference on Data Engineering Workshops (ICDEW'06)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2006-04-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116150075","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}

Hsu, Rahul Singh","doi":"10.1109/ICDEW.2006.11","DOIUrl":"https://doi.org/10.1109/ICDEW.2006.11","url":null,"abstract":"While increasing amounts of complex information are becoming available on the web, there is, beyond keywordbased search and listing of results, a paucity of user interface paradigms and implementations that support interaction, exploration, and assimilation of information. This paper describes our design of a novel framework to address this deficiency. The proposed framework supports both direct search behavior as well as more exploratory search strategies through multiple-perspective visualization and interaction with search results. The approach is developed around the twin themes of supporting data context and facilitating effective interactions between users and data. The system supports data context through determination of semantic correlations between web pages and extraction of the spatio-temporal data contained therein. A multipleperspective environment is then used to display semantic and spatio-temporal relationships as well as to provide intuitive views of the data, specifically through web page thumbnail, map, and timeline modules. The environment supports direct interactions with the data through a reflective interface by which user selections in any one panel highlight the corresponding information in other panels. In this environment, visual cues and explicit facilities to model space and time aid in recognition, querying, and exploration of information as well as in representation and reasoning with complex relationships (such as spatio-temporal, causal, evolutionary) in the data. Experimental studies of a quantitative and qualitative nature demonstrate the efficacy of the system in facilitating both information extraction and discovery.","PeriodicalId":331953,"journal":{"name":"22nd International Conference on Data Engineering Workshops (ICDEW'06)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2006-04-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114298304","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}
