Research on multi-record matching strategy benefits to the quality of assessment results on complex information system skills. This paper takes ERP software as an example and studies the multi-record matching strategy. It firstly designs and implements five record-matching methods, depending on the keywords, the local optimal accuracy, the local optimal scores, the global optimal accuracy and the global optimal scores, and then carries on the comparison to the effect of them. The keywords matching means that all the scoring fields in one record are matched, then the whole record is deemed to be matched. The optimal method refers to selecting the record with the maximum accuracy or scores as the matched record. The local way of matching relies on the order of the records, whereas the global one considers all the possible matches for the determination of the result. When using the accuracy as the optimal selection basis, the number of matching fields in one record must be counted. At the time if the scores are the criteria, the scores of matched fields need to be calculated before working out the final matched records. The paper is aim to help carry out the study in skills assessment and the practical work of complex information system.","PeriodicalId":350703,"journal":{"name":"2020 15th International Conference on Computer Science & Education (ICCSE)","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115667205","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}

Recently some eye-tracking based approaches have been proposed to analyze students’ cognitive process in programming, but few of them focused on the performance assessment in programming courses. In our previous work, an eye-tracking assisted framework was proposed to assess the overall performance of one student in a web-based error-find test. Aiming to provide individual diagnostics, we extend that work in this paper, and study 15 students’ performance in different phases of the online test. For each student, his performance is analyzed in two phases, i.e. the code overview phase and the subsequent phase. In the first phase, the behavior of first-time code browsing and first-time error finding is studied and compared. We find that the performance of first error-finding action has obvious correlation with the final test score. In the subsequent phase, the students’ performances are examined in activity sequence separated by the click events. We propose a new metric, namely matched ratio of program execution, to describe the proportion of gaze path matching with the program execution. Data analysis results show that, it is more helpful in interpreting students’ behavior and describing the students’ working efficiency in the test.","PeriodicalId":350703,"journal":{"name":"2020 15th International Conference on Computer Science & Education (ICCSE)","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123877190","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}

Because the documents have almost the same contents, it is impossible to discover copied ones by reading and comparing their contents in detail. However, copied documents will have similar or even the same file properties to the original ones. That makes it possible to identify the suspicious copied documents with similar file properties. We develop a tool software to process the comparisons automatically. It is based on an open source third-party library, and is developed in .NET as a Windows Form application. It simply reads the file properties, and calculates the hash strings from them. It is not necessary to compare every pair of hash strings. It is just needed to sort all the files by their hash strings, then the files with the same hash strings will be put together. The tool software is named iSchood, which means Identifying Suspicious Copied HOmewOrk Documents. By this software, the suspicious copied documents can be identified in a fast and lightweight way.","PeriodicalId":350703,"journal":{"name":"2020 15th International Conference on Computer Science & Education (ICCSE)","volume":"53 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122943223","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}

With the performance improvement, the maturity of virtualization technology and many open-source network projects (such as DPDK), the general-purpose multi-core processors (multi-core CPU) have been widely used in network field. Network operators are migrating network functions to multi-core CPU for flexible development and dynamic deployment. Network programming interfaces on multi-core CPU not only provide general packet processing services but also shield the complex implementation of software and hardware for developers. Both network application requirements and implementation mechanisms of the underlying platform have significant influences on the development of network programming interfaces. In this paper, we first review the development of network programming interfaces and classify programming interfaces by information model, resource management mode, and development model. We then analyze the programming interfaces provided by Click, VPP, and mOS, respectively. Because 5G and data center networks require high programmability and performance, and software/hardware co-processing become popular packet processing architectures, we also propose future research directions, including application-defined semantics of control blocks, software/hardware dynamical reconfiguration, and multi-dimensional event management.","PeriodicalId":350703,"journal":{"name":"2020 15th International Conference on Computer Science & Education (ICCSE)","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129635977","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 construction capability has been enhanced steadily, while the number and quality of digital education resources has witnessed substantial improvement. Given the wide coverage of our external learning centers (311 off-campus learning centers in over 20 provinces, including municipalities and autonomous regions, and over 100 Aopeng off-campus learning centers), some centers, with limited funding, is facing problems like high software development costs and maintenance and upgrading difficulties. On-line software service based on SaaS is a newly-emerged software application mode and also one of the three cloud computing modes. In this thesis, the on-line learning platform based on SaaS mode, being practical, universally-applicable, flexible and extendable, transformed educational software from traditional products into service, which could greatly reduce software and hardware and thereby better serve the remote continuing education in our school.","PeriodicalId":350703,"journal":{"name":"2020 15th International Conference on Computer Science & Education (ICCSE)","volume":"37 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125709370","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}
