In this paper, we attempt to collate a list of software testing job responsibilities by applying three different social research methodologies to collect information from different sources. We found that “test” specific responsibilities are divided into several unit tasks including test suite generation, execution of test plans, and so on. We also found that along with test specific responsibilities, software testers must perform a number of other tasks common to other IT professionals in order to carry out their roles.","PeriodicalId":165006,"journal":{"name":"2014 IEEE Symposium on Visual Languages and Human-Centric Computing (VL/HCC)","volume":"74 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-08-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126096151","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}

As in textual languages, comments can make diagrams easier to understand. In the absence of an explicit attachment between comments and the diagram elements they relate to, that relationship is usually given implicitly by the manual placement of comments near the related elements. While algorithms for the automatic layout of diagrams can make working with diagrams more effective, they usually fail to preserve implicit attachments by placing comments at arbitrary positions. In this paper, we propose a comment attachment algorithm that extracts implicit attachments and makes them accessible to layout algorithms. We implemented the algorithm in an application for browsing Ptolemy diagrams and achieved success rates, i. e. attachments as intended by the user, of up to 90 %.","PeriodicalId":165006,"journal":{"name":"2014 IEEE Symposium on Visual Languages and Human-Centric Computing (VL/HCC)","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-08-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114888700","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}

Existing methods which combine both Euler diagrams and graphs such as Bubble Sets and Euler View provide somewhat limited results with suboptimal layout. In particular, they do not produce diagrams that are known to be most effective for performing user-driven tasks. That said, our knowledge is rather limited about what constitutes an effective layout for Euler diagrams and graphs in combination. Our ultimate aim is to automatically visualise large networks in an effective manner. To produce effective layouts, we need to identify properties that may correlate with effective layouts of Euler diagrams combined with graphs. Such properties are considered in this paper. In future, empirical studies will be conducted to inform and validate the combined properties.","PeriodicalId":165006,"journal":{"name":"2014 IEEE Symposium on Visual Languages and Human-Centric Computing (VL/HCC)","volume":"59 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-08-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116592450","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 applies not just to scientists, but also to consumers who are gaining unprecedented access to data from their cars, homes, phones, and other devices. Meanwhile, visualization has emerged as an effective tool for exploring and gathering insight from large quantities of data. However, constructing effective visualizations is often difficult, and current tools often lack either the flexibility to extend to custom problem domains or else require low-level graphics programming expertise to generate even simple visualizations. Furthermore, most solutions are ad hoc, preventing users from transforming and evolving visualizations, instead forcing them into a rigid, linear workflow. One possible approach to solving these problems is through the definition of a domain-specific language (DSL). This approach offers a number of potential advantages, the most immediate being flexibility. A visualization DSL could support multiple levels of abstraction at once, each of which could be targeted at different user needs and expertise levels. This, in turn, could allow users with varying levels of expertise to make use of the abstraction layers they find most appropriate, and support the creation of simple and common visualizations without sacrificing the option for more detailed control when necessary. This layering could also allow implementation details to be hidden when desired. Pixel position information, for example, could be hidden behind a scalable and unitless environment which would allow the user to place and size visualization components in relation to one another.","PeriodicalId":165006,"journal":{"name":"2014 IEEE Symposium on Visual Languages and Human-Centric Computing (VL/HCC)","volume":"34 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-08-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132438372","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}

Previous research suggests that 88% of manually-composed queries retrieve no relevant results. Many searches fail because existing search tools depend solely on string matching with a manually-composed query, which cannot find semantically-related code. To solve this problem, researchers proposed query recommendation techniques to help developers compose queries without the extensive knowledge of the codebase under search. However, few of these techniques are empirically evaluated by the usage data from real-world developers. To fill this gap, we studied several query recommendation techniques by extending Sando and conducting a longitudinal field study. Our study shows that over 30% of all queries were adopted from recommendation; and recommended queries retrieved results 7% more often than manual queries.","PeriodicalId":165006,"journal":{"name":"2014 IEEE Symposium on Visual Languages and Human-Centric Computing (VL/HCC)","volume":"105 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-08-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122219357","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}
