Organizational memory: A model based on a heterogeneous network and an automatic information integration process 组织记忆:一个基于异构网络和信息自动集成过程的模型
Jérémy Bascans, M. Chevalier, Patrice Gennero, C. Soulé-Dupuy
Organizational memory is a space where various information circulating in a company are capitalized. From the users' point of view, an organizational memory, which can be seen as an information system component, is very important since it stores the “shared knowledge” of the organization. But, at the same time, the cost of this knowledge is relatively high since users' participation, i.e. to integrate/maintain... the memory is important. The aim of our work is to model an organizational memory through a heterogeneous network on which is based an automatic information integration process to assist users in this task while limiting their effort. We developed a prototype and evaluated through an experiment its ability to integrate new information into an organizational memory based on the proposed model.
组织记忆是公司中流通的各种信息被资本化的空间。从用户的角度来看,组织记忆可以看作是一个信息系统组件,因为它存储了组织的“共享知识”,因此非常重要。但与此同时,由于用户的参与,这些知识的成本相对较高,即集成/维护…记忆很重要。我们工作的目的是通过一个基于自动信息集成过程的异构网络来建立一个组织记忆模型,以帮助用户完成这项任务,同时限制他们的努力。我们开发了一个原型,并通过实验评估了它基于所提出的模型将新信息整合到组织记忆中的能力。

SGAC: A patient-centered access control method SGAC:以患者为中心的访问控制方法
N. Huynh, M. Frappier, Herman Pooda, A. Mammar, Régine Laleau
This paper presents SGAC(Solution de Gestion Automatisée du Consentement, automatised consent management solution), a new healthcare access control model and its support tool, that manages patient wishes regarding access to their electronic health record (EHR). The development of this model has been achieved in the scope of a project with the Sherbrooke University Hospital, and thus has been adapted to take into account laws and regulations applicable in Québec and Canada, as they set bounds to patient wishes: under strictly defined contexts, patient consent can be overridden to protect his/her life. Moreover, since patient wishes and laws can be in conflict, SGAC provides a mechanism to address this problem. Besides, laws do not cover all cases where consent should be overridden to ensure patient safety. To this end, we define a formal model of SGAC which allows for property verification, making it possible to detect these cases. A performance comparison with XACML (WSO2/Balana) is presented and demonstrates the superior performances of SGAC.
本文介绍了SGAC(自动同意管理解决方案),这是一种新的医疗保健访问控制模型及其支持工具,用于管理患者对其电子健康记录(EHR)的访问意愿。这一模式是在与舍布鲁克大学医院合作的一个项目范围内开发的,因此已经进行了调整,以考虑到科威特和加拿大适用的法律和条例,因为这些法律和条例对病人的愿望设定了界限:在严格界定的情况下,可以不考虑病人的同意,以保护他/她的生命。此外,由于患者的愿望和法律可能存在冲突,SGAC提供了一种解决这一问题的机制。此外,法律并没有涵盖所有为了确保病人安全而不考虑同意的情况。为此,我们定义了一个正式的SGAC模型,该模型允许进行属性验证,从而可以检测到这些情况。通过与XACML (WSO2/Balana)的性能比较,证明了SGAC的优越性能。

Process mining for recommender strategies support in news media 新闻媒体推荐策略支持的过程挖掘
Elena V. Epure, Jon Espen Ingvaldsen, R. Deneckère, C. Salinesi
The strategic transition of media organizations to personalized information delivery has urged the need for richer methods to analyze the customers. Though useful in supporting the creation of recommender strategies, the current data mining techniques create complex models requiring often an understanding of techniques in order to interpret the results. This situation together with the recommender technologies deluge and the particularities of the news industry pose challenges to the news organization in making decisions about the most suitable strategy. Therefore, we propose process mining as a high-level, end-to-end solution to provide insights into the consumers' behavior and content dynamics. Specifically, we explore if it allows news organizations to analyze independently and effectively their data in order to support them in defining recommender strategies. The solution was implemented in a case study with the third largest news provider in Norway and yielded preliminary positive results. To our knowledge, this is the first attempt to apply a process mining methodology and adapt the techniques to support media industry with the recommender strategies.
媒体组织向个性化信息传递的战略转变促使人们需要更丰富的分析客户的方法。虽然在支持创建推荐策略方面很有用,但当前的数据挖掘技术创建了复杂的模型,通常需要理解技术才能解释结果。这种情况,再加上推荐技术的泛滥和新闻行业的特殊性,对新闻机构如何选择最合适的策略提出了挑战。因此,我们建议将流程挖掘作为一种高级的端到端解决方案,以提供对消费者行为和内容动态的洞察。具体来说,我们探索它是否允许新闻机构独立有效地分析他们的数据,以支持他们定义推荐策略。该解决方案已在挪威第三大新闻提供商的案例研究中实施,并产生了初步的积极结果。据我们所知,这是第一次尝试应用过程挖掘方法并调整技术以支持媒体行业的推荐策略。

Conversational agent for mobile-learning: A review and a proposal of a multilanguage text-to-speech agent, “MobiSpeech” 面向移动学习的会话代理:多语言文本到语音代理“mobisspeech”的回顾与建议
Mouna Abdelkefi, I. Kallel
The new Information, communication, and mobile technologies empower the users to learn anywhere and anytime. They also need conversational systems that could be aware of their mobile context in order to adjust it dynamically. The actual research field is focusing on adaptive conversational systems, especially in the case of Mobile-learning. This paper presents a comparative study of some related works. Then, it proposes an M-learning architecture based on hybrid cooperative agents (mobile, conversational, cognitive), with the possibility integrating Multi-Language ontology for the development of a Conversational Agent (CA) speaking Multi-Language especially Arabic language. A prototype of text-to-speech mobile agent (MobiSpeech) is presented and discussed. MobiSpeech is intended for mobile users, and provide all services to read any text and any text file extension for the user while considering the existing context-awareness.
新的信息、通信和移动技术使用户能够随时随地学习。他们还需要能够意识到移动环境的对话系统,以便动态调整它。实际的研究领域集中在自适应会话系统,特别是在移动学习的情况下。本文对相关著作进行了比较研究。然后,提出了一种基于混合协作代理(移动、会话、认知)的移动学习体系结构,并集成了多语言本体,用于开发多语言(特别是阿拉伯语)会话代理(CA)。提出并讨论了文本转语音移动代理(MobiSpeech)的原型。MobiSpeech面向移动用户,在考虑现有上下文感知的情况下,为用户提供读取任意文本和任意文本文件扩展名的所有服务。

Building a rationale diagram for evaluating user story sets 为评估用户故事集构建一个基本原理图
Yves Wautelet, Samedi Heng, Manuel Kolp, I. Mirbel, S. Poelmans
Requirements representation in agile methods is often done on the basis of User Stories (US) which are short sentences relating a WHO, WHAT and (possibly) WHY dimension. They are by nature very operational and simple to understand thus very efficient. Previous research allowed to build a unified model for US templates associating semantics to a set of keywords based on templates collected over the web and scientific literature. Since the semantic associated to these keywords is mostly issued of the i* framework we overview in this paper how to build a custom rationale diagram on the basis of a US set tagged using that unified template. The rationale diagram is strictly speaking not an i* strategic rationale diagram but uses parts of its constructs and visual notation to build various trees of relating US elements in a single project. Indeed, the benefits of editing such a rationale diagram is to identify depending US, identifying EPIC ones and group them around common Themes. The paper shows the feasibility of building the rationale diagram, then points to the use of these consistent sets of US for iteration content planning. To ensure the US set and the rationale diagram constitute a consistent and not concurrent whole, an integrated Computer-Aided Software Engineering (CASE) tool supports the approach.
敏捷方法中的需求表示通常是在用户故事(US)的基础上完成的,用户故事是与WHO、WHAT和(可能)WHY维度相关的短句。它们本质上是非常可操作的,易于理解,因此非常有效。先前的研究允许为美国模板建立一个统一的模型,该模型将语义与一组基于从网络和科学文献中收集的模板的关键字关联起来。由于与这些关键字相关的语义主要是由i*框架发布的,我们在本文中概述了如何在使用统一模板标记的美国集合的基础上构建自定义的基本原理图。严格来说,基本原理图不是i*战略基本原理图,而是使用其部分结构和可视化符号来构建单个项目中相关元素的各种树。事实上,编辑这样一个基本原理图的好处是识别不同的US,识别EPIC,并将它们围绕共同的主题进行分组。本文展示了构建基本原理图的可行性,然后指出使用这些一致的US集进行迭代内容规划。为了确保US集和基本原理图构成一个一致的而不是并发的整体,一个集成的计算机辅助软件工程(CASE)工具支持该方法。

Taking into account the evolution of users social profile: Experiments on Twitter and some learned lessons 考虑到用户社交资料的演变:在Twitter上的实验和一些经验教训
Sirinya On-at, A. Quirin, A. Péninou, Nadine Baptiste-Jessel, Marie-Françoise Canut, F. Sèdes
Incorporating user interests evolution over time is a crucial problem in user profiling. We particularly focus on social profiling process that uses information shared on user social network to extract his/her interests. In this work, we apply our existing time-aware social profiling method on Twitter. The aim of this study is to measure the effectiveness of our approach on this kind of social network platform, which has different characteristics from those of other social networking sites. Although the improvement compared to the time-agnostic baseline method is still low, the experiments using a parametric study showed us the benefit of applying a time-aware social profiling process on Twitter. We also found that our method performs well on sparse networks and that the information dynamic influences more the quality of our proposed time-aware method than the relationships dynamic while building the social profile on Twitter. This observation will lead us to a more complex study to find out meaningful factors to incorporate user interests evolution on social profiling process in such a network.
结合用户兴趣随时间的演变是用户分析中的关键问题。我们特别关注社会分析过程,利用用户在社交网络上共享的信息提取他/她的兴趣。在这项工作中,我们在Twitter上应用了现有的时间感知社交分析方法。本研究的目的是衡量我们的方法在这类社交网络平台上的有效性,这类社交网络平台与其他社交网站具有不同的特点。虽然与时间无关的基线方法相比,改进仍然很低,但使用参数研究的实验表明,在Twitter上应用时间敏感的社会分析过程有好处。我们还发现,我们的方法在稀疏网络上表现良好,并且在Twitter上建立社交档案时,信息动态比动态关系对我们提出的时间感知方法的质量影响更大。这一观察结果将引导我们进行更复杂的研究,以找出有意义的因素,将用户兴趣演变纳入这种网络的社会概况过程。

An example of empirical approach for bibliographic record linkage 书目记录联动的实证方法实例
A. Knyazeva, O. Kolobov, I. Turchanovsky
The record linkage problem in application to a bibliographic and authority data is considered. The problem is common in the situation of merging data from several libraries. The two approaches based on empirical analysis of data are tested. Both of them involve an indirect information about a person. The proposed variant of the decision tree method allows us to deal with inconsistent bibliographic data and to use particular rules one by one for improving of record linkage quality. The study was performed on data of several Russian libraries. The data we deal with are in RUSMARC format which is a variant of UNIMARC popular in Russia.
研究了书目与权威数据应用中的记录联动问题。在合并来自多个库的数据的情况下,这个问题很常见。基于数据的实证分析对两种方法进行了检验。它们都涉及一个人的间接信息。本文提出的决策树方法的变体允许我们处理不一致的书目数据,并逐个使用特定的规则来提高记录链接的质量。这项研究是根据几个俄罗斯图书馆的数据进行的。我们处理的数据是RUSMARC格式,这是俄罗斯流行的UNIMARC的一种变体。

Personalized information retrieval models integrating the user's profile 集成用户配置文件的个性化信息检索模型
Chahrazed Bouhini, M. Géry, C. Largeron
Personalized Information Retrieval (PIR) exploits the user's data in order to refine the retrieval, like for instance when users with different backgrounds may express different information needs with the same query. However, this additional source of information is not supported by the classical Information Retrieval (IR) process. In order to overcome this limit, we propose to generate the user profile out from his profile and social data. Then, we introduce several Personalized Information Retrieval models which integrate this profile at the querying step, allowing to personalize the search results. We study several combinations of the initial user's query with his profile. Furthermore, we present a PIR test collection that we built from the social bookmarking network Delicious, in order to evaluate our PIR models. Our experiments showed that the PIR models improve the retrieval results.
个性化信息检索(PIR)利用用户的数据来优化检索,例如当不同背景的用户可能对同一查询表达不同的信息需求时。然而,经典的信息检索(information Retrieval, IR)过程不支持这种额外的信息源。为了克服这一限制,我们建议从他的个人资料和社交数据中生成用户的个人资料。然后,我们引入了几个个性化信息检索模型,这些模型在查询步骤中集成了该配置文件,允许对搜索结果进行个性化。我们研究了初始用户查询与其个人资料的几种组合。此外,为了评估我们的PIR模型,我们展示了从社交书签网络Delicious构建的PIR测试集。我们的实验表明,PIR模型提高了检索结果。

Trading exploits online: A preliminary case study 在线交易漏洞:初步案例研究
Jukka Ruohonen, S. Hyrynsalmi, V. Leppänen
A software defect that exposes a software system to a cyber security attack is known as a software vulnerability. A software security exploit is an engineered software solution that successfully exploits the vulnerability. Exploits are used to break into computer systems, but exploits are currently used also for security testing, security analytics, intrusion detection, consultation, and other legitimate and legal purposes. A well-established market emerged in the 2000s for software vulnerabilities. The current market segments populated by small and medium-sized companies exhibit signals that may eventually lead to a similar industrialization of software exploits. To these ends and against these industry trends, this paper observes the first online market place for trading exploits between buyers and sellers. The paper adopts three different perspectives to study the case. The paper (a) portrays the studied exploit market place against the historical background in the software security industry. A qualitative assessment is made to (b) evaluate the case against the common characteristics of traditional online market places. The qualitative observations are used in the quantitative part (c) for predicting the price of exploits with partial least squares regression. The results show that (i) the case is unique from a historical perspective, although (ii) the online market place characteristics are familiar. The regression estimates also indicate that (iii) the pricing of exploits is only partially dependent on such factors as the targeted platform, the date of disclosure of the exploited vulnerability, and the quality assurance service provided by the market place provider. The results allow to contemplate (iv) practical means for enhancing the market place.
使软件系统暴露于网络安全攻击的软件缺陷被称为软件漏洞。软件安全漏洞是成功利用漏洞的工程软件解决方案。漏洞利用通常用于入侵计算机系统,但目前也用于安全测试、安全分析、入侵检测、咨询和其他合法目的。2000年代,一个成熟的软件漏洞市场出现了。目前由中小型公司组成的细分市场显示出可能最终导致类似的软件利用工业化的信号。为了达到这些目的,并针对这些行业趋势,本文观察了买方和卖方之间交易漏洞的第一个在线市场。本文采用三种不同的视角来研究这个案例。本文(a)在软件安全行业的历史背景下描绘了所研究的开发市场。进行定性评估,以(b)根据传统在线市场的共同特征评估案例。定性观察结果用于定量部分(c),用偏最小二乘回归预测漏洞的价格。结果表明:(i)从历史角度来看,该案例是独一无二的,尽管(ii)在线市场特征是熟悉的。回归估计还表明(iii)漏洞的定价仅部分取决于目标平台、被利用漏洞的披露日期以及市场提供商提供的质量保证服务等因素。研究结果可让我们思考(iv)改善市场环境的实际方法。

The current market segments populated by small and medium-sized companies exhibit signals that may eventually lead to a similar industrialization of software exploits. To these ends and against these industry trends, this paper observes the first online market place for trading exploits between buyers and sellers. The paper adopts three different perspectives to study the case. The paper (a) portrays the studied exploit market place against the historical background in the software security industry. A qualitative assessment is made to (b) evaluate the case against the common characteristics of traditional online market places. The qualitative observations are used in the quantitative part (c) for predicting the price of exploits with partial least squares regression. The results show that (i) the case is unique from a historical perspective, although (ii) the online market place characteristics are familiar. The regression estimates also indicate that (iii) the pricing of exploits is only partially dependent on such factors as the targeted platform, the date of disclosure of the exploited vulnerability, and the quality assurance service provided by the market place provider. The results allow to contemplate (iv) practical means for enhancing the market place.","PeriodicalId":344289,"journal":{"name":"2016 IEEE Tenth International Conference on Research Challenges in Information Science (RCIS)","volume":"113 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124317893","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}

Developing web applications for different architectures: The MoWebA approach 为不同的架构开发web应用程序:MoWebA方法
Magalí González, L. Cernuzzi, Nathalie Aquino, Ó. Pastor
This study presents the Architecture Specific Model (ASM) defined by the MoWebA approach to improve the development of web applications for different architectures. MoWebA is a model-driven approach to web applications development. The article presents a general overview of MoWebA, including the methodological aspects related to its modeling and transformation processes, the process of defining the ASM, and an example of an ASM model. We finally present a preliminary validation experience and its main results. The experience was structured according to the proposal of Runeson et al. for case studies.
