It's been over 25 years since the GIF format was introduced, and we've since then made significant progress in video compression. By converting GIF to video formats, you not only gain the possibility of user interaction, but you also reduce its size significantly without any noticeable loss of quality. The paper will present a way to achieve this using FFmpeg, utilizing commands which has been specifically optimized for the purpose of GIF to HTML5 Video conversion. The average GIF will load 8 times faster after it has been converted to video formats, and users who don't support HTML5 Video will have access to the original GIF. Converting GIF to video formats offer many benefits and little to no drawbacks (as long as the original GIF remains available). It is therefore in the best interest for both businesses and consumers to convert GIF to HTML5 Video, thus optimizing GIF for modern browsers.","PeriodicalId":366169,"journal":{"name":"2014 11th Web Information System and Application Conference","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-09-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127503318","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}

Our paper focuses on finding top-k frequent items on timestamp-based complicated streams, and proposes an approximate solution by sampling. Specifically, we design a multi-treap parallel priority algorithm to maintain uniform sample on timestamp-based sliding windows. The top-k answers are approximated through processing on samples. We also theoretically analyze the relationship between item accuracy and sample size. Through experimental analysis on real data, our method provides flexible sample size to satisfy different accuracy requirements and ensure a good running efficiency.","PeriodicalId":366169,"journal":{"name":"2014 11th Web Information System and Application Conference","volume":"53 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-09-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115931888","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}

This paper focuses on the security standard for 5G network, which is one key component covering whole system. The objective is to provide a general protection scheme for both whole infrastructure and some critical components, without introducing too much overhead. The unified security architecture is presented for 5G in order to meet the increasing security requirement. The architecture is more efficient for new standard to cope with threats from both WLAN (Wireless Local Area Network) and mobile access equipments in a consistent way. Therefore a unified security architecture is proposed which contains differentiated counter-measures for these threats. Specifically, the security architecture integrates six modules: unified authentication, additional authentication, encryption, unified access, additional access, and unified integrated security.","PeriodicalId":366169,"journal":{"name":"2014 11th Web Information System and Application Conference","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-09-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127801000","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 query results are presented in dynamically generated web pages, usually in the form of data records, for human use. The automatical web data extraction is critical in web integration. A number of approaches have been proposed. The early work are most based on the source code or the tag tree of the page. Recent approaches use the visual feature to extract data information, which are better than the previous work. However, these approaches still have inherent limitation. In this paper, we propose a novel approach that make use of visual features to extract data information from web page, including the data records and the data items. The results of this experiment tests on a large set of query result pages in different domain show that the proposed approach is highly effective.","PeriodicalId":366169,"journal":{"name":"2014 11th Web Information System and Application Conference","volume":"46 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-09-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130190269","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}

This paper describes Type, a tool that works for static type annotation and inference for python. It could simulate the built-in modules, transform the Python source code to IR(Intermediate representation) which we design and annotate, infer and reduce the IR into the type system. Type could provide the explicit type information, detect the type errors at compile time and improve the efficiency of development and the accuracy of point-to analysis. By the evaluation of applying Type to a suite of benchmarks, we find that Type can annotate and infer the types with a good precision and coverage in accept time.","PeriodicalId":366169,"journal":{"name":"2014 11th Web Information System and Application Conference","volume":"44 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-09-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134490225","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}

This paper proposes PTEP (the Prediction of Topic Energy Peak) method to model the life cycle of a topic and predicts the time when a hot topic will outbreak. Firstly, taking the number and the authority of followers and the interest of users to a topic into consideration, we design a topic-related user authority (TRUA) algorithm to measure the authority of users. Secondly, we calculate the energy value considering both the tweets and users authority related to the topic. Thirdly, we measure the fluctuation of the energy value based on wavelet transformation. Finally, we present rules to predict topic trend. Experimental results show that our method can effectively predict the peak of a topic in advance with a low omission rate.","PeriodicalId":366169,"journal":{"name":"2014 11th Web Information System and Application Conference","volume":"68 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-09-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128714682","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}
