Generating Product Feature Hierarchy from Product Reviews 10th

Generating Product Feature Hierarchy from Product Reviews

引用

10th International Conference on Web information Systems and Technologies (WEBIST)

作者： Tian, Nan Xu, Yue Li, Yuefeng Abdel-Hafez, Ahmad Josang, Audun Queensland Univ Technol Fac Sci & Engn Brisbane Qld 4001 Australia Univ Oslo Dept Informat N-0316 Oslo Norway

User generated information such as product reviews have been booming due to the advent of web 2.0. In particular, rich information associated with reviewed products has been buried in such big data. In order to facilitate identifying useful information from product (e.g., cameras) reviews, opinion mining has been proposed and widely used in recent years. In detail, as the most critical step of opinion mining, feature extraction aims to extract significant product features from review texts. However, most existing approaches only find individual features rather than identifying the hierarchical relationships between the product features. In this paper, we propose an approach which finds both features and feature relationships, structured as a feature hierarchy which is referred to as feature taxonomy in the remainder of the paper. Specifically, by making use of frequent patterns and association rules, we construct the feature taxonomy to profile the product at multiple levels instead of single level, which provides more detailed information about the product. The experiment which has been conducted based upon some real world review datasets shows that our proposed method is capable of identifying product features and relations effectively.

Many software development projects fail due to problems in requirements, scope, and collaboration. This paper presents a case study of the mismatch between the expectations of Product Owners and the outcome of the development in a large distributed Scrum organization. The data was collected in retrospective meetings involving a team of Product Owners and two software development teams. A focused root cause analysis of the problem "Why the expectations of Product Owners do not meet the outcome of development teams?" was conducted. The analysis aimed at explaining why the problem occurred and how the causes were related to one another. The outcomes were analyzed both quantitatively and qualitatively. Our results illustrate the challenges of implementing the Product Owner role in the context of complex, high-variability requirements and distributed development. We highlight the importance of true collaboration, effective requirements specification activities, and sufficient resources for the Product Owner role.

Access control systems are designed to allow or deny access to data according to organizational policies. In many organizations, the access rights of subjects to data objects are determined in consideration of clearance levels of subjects and classification levels of objects. In most formally-defined traditional access control systems, levels are predetermined and policies are rigid. However, in practice organizations need to use flexible methods where the levels are determined dynamically by information flow criteria. In this paper, we develop a method that is both formal and flexible to determine entities' security levels on the basis of access history, which characterizes the data that subjects can know or objects can contain. Our approach is motivated with a number of different examples, showing that the method meets real-life organizational requirements.

Annotation paths are a new method for semantic annotation, which overcomes the limited expressiveness of concept references as defined in the SAWSDL standard. We introduce annotation paths and show how annotation paths can be applied for service matching capturing the semantics of XML schemas and web service descriptions more precisely. We report some experimental evaluation of the feasibility of annotation paths for web service discovery. The experiments suggest that annotation paths appears as a promising approach for improving web service discovery.

Pattern-Based Security Requirements Derivation from Secure Tropos Models 8th

8th IFIP WG 8.1 Working Conference on the Practice of Enterprise Modeling (PoEM)

作者： Rrenja, Atilio Matulevicius, Raimundas Univ Tartu Inst Comp Sci Ulikooli 18 EE-50090 Tartu Estonia

The increasing rates of cyber-attacks have led to the subsequent need to rapidly develop secure information systems (IS). Secure Tropos is an actor and goal-oriented approach to identify security goals and to enable security requirements elicitation. This is achieved by considering system actors, their dependencies and by deriving security constraints that actors need to satisfy. Nevertheless goal-oriented modelling has proven itself to be valid it also contains few shortcomings. One of them is the high granularity of the process, which leads quickly to high complexity models. Security patterns are proven to be reusable solutions that address recurring security problems. In this paper we investigate the integration of a pattern-based security requirements derivation from the Secure Tropos models.

Significant progress in ontology engineering during the last decade resulted in a growing interest in using ontologies for industrial applications. This paper presents lessons learned and recommendations for ontology engineering projects with focus on industrial applications. The research is based on the analysis of a number of case studies in different industrial domains. Based on the case studies the paper presents experiences from ontology development and gives recommendations for industrial ontology construction projects. The recommendations concern (1) selection of development methods, (2) perspectives on generalisation/specialisation strategy, (3) aspects of user participation in ontology construction and (4) effects on knowledge management in organizations.

8th IFIP WG 8.1 Working Conference on the Practice of Enterprise Modeling (PoEM)

Nowadays enterprises are searching the efficient compliance management method. Being compliant could potentially help capturing the most important information, using practice and existing process solutions;thus reducing the management effort and cost. When it comes to the security compliance management, it means treating and reducing the security risks to the acceptable level and employing the validated and cost effective security countermeasures. However, the typical question that small and medium enterprises face, is on how to achieve the security compliance in the efficient way. In this paper we report on our experience to use the security risk-oriented patterns to improve business processes of the insurance brokerage. The analysed case showed the major steps to apply the regulatory standard to check compliance, as well as the major procedures needed to improve the business process compliance. The lessons learnt highlight some method guidelines toward compliance management and suggest needed improvement directions for the application of the security risk-oriented patterns.

Introducing a Socio-Technical Perspective on business Processes into Enterprise Interoperability Frameworks 6

6th International IFIP Working Conference on Enterprise Interoperability (IWEI)

ISBN: (纸本)9783662471579;9783662471562

This paper looks at enterprise interoperability (EI), specifically process-level interoperability, and suggests that the inherent non-determinacy of human-centred business processes introduces another ingredient into the EI puzzle that has thus far been understated in EIF ontologies. A conceptualisation of business process based on socio-technical concepts is presented. It is argued that this provides a better way to accommodate human agency factors, and under the influence of these factors, how business processes inevitably evolve over time, potentially affecting their interoperability. We suggest the extant body of knowledge on the theory of dynamic capabilities is relevant to understanding how organisations can control this potentially undirected process evolution and thereby sustain interoperability. Some initial observations are made concerning how this new ontological element could be accommodated into existing EIFs. The paper aims to stimulate discussion in this area and make a contribution to the EI body of knowledge.

Change requests are inevitable in every phase of the Software Development Life Cycle (SDLC), and responding to a change request without jeopardizing the project success remains a challenge for software developers/managers. Expressing functional changes in terms of COSMIC Function Point units can be helpful in identifying changes leading to a potential impact on the software functional size;this latter can be used as a means to plan the project activities. This paper proposes to analyze the impact of functional changes on the size of UML activity diagrams, one artifact type produced early in the SDLC. The proposed analysis handles directly as well as indirectly affected elements in both modelling levels of the activity diagrams.

12th International Conference on business Process Management (BPM)

Today, essentially all industry sectors are developing and applying "big data analytics" to gain new business insights and new operational efficiencies. Essentially two forms of analytics processing support these business-targeted applications: (i) "analytics explorations" that search for business-relevant insights in support of description, prediction, and prescription;and (ii) "analytics flows" that are deployed and executed repeatedly to apply such insights to support reporting and enhance existing business processes. The human environment that surrounds business-targeted analytics involves a multitude of stake-holder roles, and a number of distinct processes are required for the development, deployment, maintanence, and governance of these analytics. This short paper presents preliminary work on a framework for Analytics Process Management (APM), a new branch of business Process Management (BPM) that is intended to address the central challenges managing analytics flows at scale. APM is focused on the processes that manage the overall lifecycle of analytics flows and their executions, and their integration into "operational" business processes that have been the traditional domain of BPM. The paper identifies key meta-data that should be maintained for analytics flows and their executions, and identifies the core business processes that are needed to create, apply, compare, and maintain such flows. The paper also raises key research questions that need to be addressed in the emerging area of APM.
