This paper evaluates the CDs framework using established conceptual frameworks for analysing scientific theories. It concludes that while it is a paradigm, it is not scientific according to standards normally applied in scientific research. It also represents the earliest evolutionary form of theory, which is appropriate when no prior theory exists. This paper asks whether such a theory is an appropriate paradigm for VL research after a quarter of a century of research in this field. The CDs framework has performed a valuable role in advancing the analysis of VLs beyond the level of intuition, but should not be seen as the end point for theory development in this field. This paper proposes a more powerful, domain-specific theory (the Physics of Notations) as an alternative paradigm for VL research.","PeriodicalId":258498,"journal":{"name":"2009 IEEE Symposium on Visual Languages and Human-Centric Computing (VL/HCC)","volume":"7 5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-09-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125857876","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}

DSLs' abstract syntax are usually defined by a metamodel. In-place model transformations provide an intuitive way to complement metamod-els with behavioral specifications. In this paper we extend in-place rules with a quantitative model of time and with mechanisms that allow designers to state action properties, facilitating the design of real-time complex systems. This approach avoids making unnatural changes to the DSL metamodels to represent behavioral and time aspects. We present the graphical modeling tool we have built for visually specifying these timed specifications.","PeriodicalId":258498,"journal":{"name":"2009 IEEE Symposium on Visual Languages and Human-Centric Computing (VL/HCC)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-09-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129614224","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}

Addressing this problem requires predicting reusability based on information that exists when a script is created. To provide such a model for web macro scripts, we identified script traits that might plausibly predict reuse, then used IBM CoScripter repository logs to statistically test how well each corresponded to reuse. We then built a machine learning model that combines the useful traits and evaluated how well it can predict four different types of reuse that we saw in the repository logs. Our model was able to predict reuse from a surprisingly small set of traits. It is simple enough to be explained in only 6–11 rules, making it potentially viable for integration in repository search engines for end-user programmers.","PeriodicalId":258498,"journal":{"name":"2009 IEEE Symposium on Visual Languages and Human-Centric Computing (VL/HCC)","volume":"50 1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-09-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128765326","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}

In this paper, we present a study that investigates the types of online information that end users encounter and the types of interactions between information sources that they imagine to be useful. To do this, we examine the first steps of the mashup creation process - data gathering and data integration. Moreover we report on the observations of end users creating a data mashup using an online tool.

The Movie-based Programming Framework allows specification of computations on regular networks of processors, and the visualization of the computation progress as processors are activated. Computations over spatial structures are specified by composing independent views on propagation of control flows and formulae defining local computations. A shape pattern indicates which processors have to be active during a specific phase of the computation. A visit pattern defines the law of propagation for actual processor activation. By combining these types of patterns, we achieve sophisticated forms of specification. In particular, one specifies visitors implementing collective communication schemas widely used in parallel programming: broadcast, gather, scatter and reduction. As a result, automatic generation of visit algorithms adapted to different network configurations is made possible, thus facilitating experimentation with different laws and their visualization.","PeriodicalId":258498,"journal":{"name":"2009 IEEE Symposium on Visual Languages and Human-Centric Computing (VL/HCC)","volume":"51 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-09-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127149970","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 studies have shown that programmers often guessed that certain classes or methods should exist, and looked for these in the API. Jadeite's “placeholders” let users add new “pretend” classes or methods that are displayed in the actual API documentation, and can be annotated with the appropriate APIs to use instead. Since studies showed that programmers had difficulty finding the right classes from long lists in documentation, Jadeite takes advantage of usage statistics to display commonly used classes more prominently. Programmers had difficulty discovering how to instantiate objects, so Jadeite uses a large corpus of sample code to automatically the most common ways to construct an instance of any given class. An evaluation showed that programmers were about three times faster at performing common tasks with Jadeite than with standard Javadoc.","PeriodicalId":258498,"journal":{"name":"2009 IEEE Symposium on Visual Languages and Human-Centric Computing (VL/HCC)","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-09-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133346874","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}
