The complex nature of the software development context and the importance of the problem has led the research community to develop several techniques, tools, and processes to assist software architects in making better decisions. Despite these effort, the adoption of such systematic approaches appears to be quite limited in practice. In addition, the practitioners are also facing new challenges as different software development methods suggest different approaches for architecture design. In this paper, we study the current software architecture decision-making practices in the industry using a case study conducted among professional software architects in three different companies in Europe. As a result, we identified different software architecture decision-making practices followed by the software teams as well as their reasons for following them, the challenges associated with them, and the possible improvements from the software architects' point of view. Based on that, we recognized that improving software architecture knowledge management can address most of the identified challenges and would result in better software architecture decision-making.","PeriodicalId":310799,"journal":{"name":"2015 24th Australasian Software Engineering Conference","volume":"37 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-09-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128957417","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 describe the UNISON middleware architecture, which seeks to provide such functionality in the form of loosely-coupled, distributed publish/subscribe messaging, distributed key-value data persistence, and basic local component control. Taken in isolation, the individual parts of UNISON encompass features already present in existing systems and infrastructures, however, UNISON combines these into a consistent whole, providing data storage/distribution and messaging/control in a simple, light-weight and unified fashion. We have prototyped UNISON as a self-standing middleware platform, and have used the resulting prototype to support a (similarly prototypical) generic, autonomous cyber defence system from DST Group's HINDER project. We discuss our experiences with UNISON in the context of this system. As the UNISON architecture is still work in progress, our aim in this paper is to describe its current state, with the belief that the underlying design decisions will provide valuable insight when attempting to design related software infrastructures for supporting cyber defence systems.","PeriodicalId":310799,"journal":{"name":"2015 24th Australasian Software Engineering Conference","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-09-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130286131","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}

An Empirical Investigation to the Capture-Recapture Method","authors":"Guoping Rong, He Zhang, Dong Shao","doi":"10.1109/ASWEC.2015.35","DOIUrl":"https://doi.org/10.1109/ASWEC.2015.35","url":null,"abstract":"Capture-recapture method is a promising technique to estimate post-inspection residual defects in the inspected software artifacts. Since decisions such as whether a re-inspection is required usually rely on the estimated number of undiscovered defects, accuracy of the capture-recapture estimates hence become one of the critical factors impacting the decisions. Among many attempts to improve the accuracy of the capture-recapture estimates, most believe (implicitly or explicitly) that an effective approach to improve the estimation accuracy is to increase inspectors' capability to detect more defects. However, few empirical evidence has been reported to support this claim. For most capture-recapture estimators, the correlation is not crystal clear between the number of detected defects and the estimation accuracy. Therefore, it is necessary to empirically evaluate this claim so as to support the rationale that inspectors improve their capability on detecting more defects in order to achieve a higher estimation accuracy. We carried out an empirical study to investigate the relationship between the estimation accuracy (represented by Relative Error) and the percentage of the number of unique defects to the total number of seeded defects (denoted by Detection Rate). Results indicate that the above claim can be safely accepted in most cases, which supports the attempts to increasing capture-recapture estimation accuracy by improving inspectors' detection capability. However, there still could be chances that the strategy to improve estimation accuracy may fail, which implies that more strategies should be explored to improvement the application of the capture-recapture method.","PeriodicalId":310799,"journal":{"name":"2015 24th Australasian Software Engineering Conference","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-09-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132021941","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}

To express static program analysis frameworks concisely, it is advantageous to employ a domain-specific language. In the last two decades, Data log has emerged as a domain-specific language for static program analysis. However, existing Data log systems have problems solving large scale code with millions of program variables. This work reports on techniques that translate a Data log program to SQL queries, which are executed on a relational database system. The advantage of a relational database system as an execution platform is the effective use of memory and disks. Further, we can also use an off-the shelf tool to execute the SQL queries. In order to achieve performance, we explore some of the design choices for a source-to-source translation from Data log to SQL that implement stratified negations, totally ordered domains, and comparisons. For each design point, we explain how Data log can be efficiently translated to SQL using the semi-naive evaluation approach. We report the results of our experiments using large data-sets including the OpenJDK7-b147 dataset for points-to, which guided us in the design of our translation schemes.","PeriodicalId":310799,"journal":{"name":"2015 24th Australasian Software Engineering Conference","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-09-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128697479","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 benefits of PEGs are twofold. First, parsing expression grammars replace unordered choice between alternatives by prioritized choice, which naturally solves the ubiquitous \"dangling else\" problem in grammar definitions. Second, PEGs employ \"character-level syntax\" specifications that eliminate the need to separate the lexical and hierarchical components of a language specification. However, there is \"no free lunch\" in PEGs. PEGs capture only syntactic relationships, but many language constructs cannot be parsed without additional semantic information. Moreover, character-level specifications can become unwieldy, as every aspect of the language, including spacing, has to be accounted for. To overcome these issues, we extend the original PEG formalism to incorporate semantic predicates that yield a programmatic means for state-based token recognition control. Furthermore, rather than requiring a single complete specification, we capture lexical components as PEG closures that provide a self-contained token recognition mechanism to reduce the clutter associated with purely character-level PEGs. To test the effectiveness of our approach, we use it for the construction of a Delphi language front-end and practically confirm that Ford's theoretical linear-time result also holds for PEG closures.","PeriodicalId":310799,"journal":{"name":"2015 24th Australasian Software Engineering Conference","volume":"51 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-09-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121083473","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 is mainly with regards to its ability to distinguish between a series of plans through a tailored plan selection function such that the plan most suitable to the current situation is selected. Since BDI agents were first proposed however, their creation process has mainly been entirely functional. This means that in order to properly implement them, specific expertise and knowledge is required. In sight of this, we propose in this paper an entirely model-driven approach based on the Extended Non-Functional Requirements framework. This approach allows agents to be directly derived from an accompanying extended NFR-framework model. The developer therefore only requires knowledge and expertise in this specific framework, which is significantly easier to understand. This derived agent can then select plans from the model's entities with respect to their hierarchy, and influenced by any contributions that they may make, selecting plans which exhibit the highest benefit to the overall system. This model-driven approach is focused on operating within a dynamic environment, which to our knowledge, is the first of its kind. This approach is evaluated experimentally.","PeriodicalId":310799,"journal":{"name":"2015 24th Australasian Software Engineering Conference","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-09-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128332947","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}

Their role in these activities is especially prominent in online application distribution platforms (OADPs), where software is developed for many potential users, and for which the traditional processes of requirements gathering and negotiation with a single group of end-users do not apply. With such vast access to end-users, however, comes the challenge of how to prioritize competing requirements in order to satisfy previously unknown user groups, especially with early releases of a product. One highly successful product that has managed to overcome this challenge is the Android Operating System (OS). While the requirements of early versions of the Android OS likely benefited from market research, new features in subsequent releases appear to have benefitted extensively from user reviews. Thus, lessons learned about how Android developers have managed to satisfy the user community over time could usefully inform other software products. We have used data mining and natural language processing (NLP) techniques to investigate the issues that were logged by the Android community, and how Google's remedial efforts correlated with users' requests. We found very strong alignment between end-users' top feature requests and Android developers' responses, particularly for the more recent Android releases. Our findings suggest that effort spent responding to end-users' loudest calls may be integral to software systems' survival, and a product's overall success.","PeriodicalId":310799,"journal":{"name":"2015 24th Australasian Software Engineering Conference","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-09-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122954065","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}
