Abstract
Purpose
Web services composition engineering (WSCE) is a big challenge because of the increasing complexity, openness and extensibility of services based on the information system (IS). In the absence of an adequate framework for IS engineering, the authors assume that the overall problem is consequently no longer easy to resolve. This paper aims to explore some of the issues underlying WSCE through a framework, which is built based on the state of the art. The proposed framework is structured around five views that mainly highlight aspects of personalization and security concerns. The main objectives of this framework are: to help understand and clarify the basics of the WSCE domain; to evaluate web services composition (WSC) methods; to analyze and compare existing personalization, secure methods and identify new research axes; and to identify the main criteria of the ongoing approach for the design of a secure IS based on personalized WSC.
Design/methodology/approach
This work develops a framework that is used as an analytical study to compare the existing WSCE methods and come up with research issues. Then, the proposed framework is considered as an abstract model for the new WSCE approach.
Findings
A set of criteria that the proposed framework should consider when developing a new approach to a secure IS based on personalized WSs composition.
Research limitations/implications
The paper has theoretical implications as the personalization and security issues provide a research roadmap toward the realization of an approach for the design of a secure IS based on personalized WSs composition.
Practical implications
As proof, the authors are interested in a web services repository of a real mall. To do this, the authors deployed the application in a cloud environment and observed the results of personalization and security concepts in WSCE.
Originality/value
None of the existing comparison frameworks has raised both personalization and security issues in WSs composition, while personalization and security must be present in the whole composition process.

Abstract
Purpose
Team composition research considers how configurations (e.g., team-level diversity) of team members’ attributes (e.g., personality, values, demographics) influence important outcomes. Our chapter describes key issues in understanding and effectively managing team composition over time.
Methodology/approach
We discuss how context shapes team composition. We review empirical research that examined relationships between team composition, and team processes and emergent properties over multiple time points. We review research that examined how composition can be effectively managed over the lifecycle of a team.
Findings
Context shapes the nature of team composition itself (e.g., dynamic composition). To the extent that membership change, fluid boundaries, and multiple team membership are present should be accounted for in research and practice. The research we reviewed indicated no, or fleeting effects for surface-level (e.g., demographics) composition on the development of team processes and emergent properties over time, although there were exceptions. Conversely, deep-level composition affected team processes and emergent properties early in a team’s lifespan as well as later. Team composition information can be used in staffing; it can also inform how to best leverage training, leadership, rewards, tasks, and technology to promote team effectiveness.
Social implications
Teams are the building blocks of contemporary organizations. Understanding and effectively managing team composition over time can increase the likelihood of team.
Originality/value
Our chapter provides novel insights into key issues in understanding and effectively managing team composition over time.

Abstract
Purpose
Web services play vital role in the development of emerging technologies such as Cloud computing and Internet of Things. Although, there is a close relationship among the discovery, selection and composition tasks of Web services, research community has treated these challenges at individual level rather to focus on them collectively for developing efficient solution, which is the purpose of this work. This paper aims to propose an approach to integrate the service discovery, selection and composition of Semantic Web services on runtime basis.
Design/methodology/approach
The proposed approach defined as a quality of service (QoS)-aware approach is based on QoS model to perform discovery, selection and composition tasks at runtime to enhance the user satisfaction and quality guarantee by incorporating non-functional parameters such as response time and throughput with the Web services and user request. In this paper, the proposed approach is based on ontology for semantic description of Web services, which provides interoperability and automation in the Web services tasks.
Findings
This work proposed an integrated framework of Web service discovery, selection and composition which supports end user to search, select and compose the Web services at runtime using semantic description and non-functional requirements. The proposed approach is evaluated by various data sets from the Web Service Challenge 2009 (WSC-2009) to show the efficiency of this work. A use case scenario of Healthcare Information System is implemented using proposed work to demonstrate the usability and requirement the proposed approach.
Originality/value
The main contribution of this paper is to develop an integrated approach of Semantic Web services discovery, selection and composition by using the non-functional requirements.

Abstract
The characteristics of individual members and how the members are assembled in a group are critical foundations for various group processes and outcomes and often determine important staffing and hiring decisions in organizations. This chapter offers an overview of the history of group composition research across multiple disciplines and identifies three distinct approaches to studying group composition with an emphasis on the role of communication. Scholars treat group composition as a cause that leads to group outcomes, a consequence that results from social and psychological processes, or a process in response to dynamic team environments. A synthesis of previous research reveals that studying group composition as a cause has dominated the field and that the role of communication in group composition has gained little attention. The chapter concludes with a set of future research directions targeting the new digital environment, the role of communication, and research methodologies with special attention to the consequence- and process-oriented approaches.

Abstract
Purpose
This paper aims to explore the feasible mining and proper selection of QoS‐aware services for a P2P‐based business process enactment framework, and enhance the relevant workflow prototype. Design/methodology/approach – Through observing and analysing unpredictable dynamic changes that commonly exist in e‐service workflow, a set of QoS specifications and monitoring mechanisms in a P2P workflow framework is proposed. These specifications are an evolving extension of services' description with semantic web facilitators for P2P‐based e‐services.
Findings
It has been demonstrated that the QoS‐OWL approach can be effectively used to describe and exploit e‐services, particularly in a decentralised environment. QoS‐OWL is also able to provide the deliberation of geographic information for e‐services, and facilitates the peers' effective cooperation and automates business processes. It is recommended that the approach be adopted in the dynamic online information system environment to increase efficiency and reduce costs in running e‐services.
Practical implications
The QoS attributes discussed in this paper are relatively typical for benchmarking purposes, so the extension of the QoS metrics specifications and related protocols need to be discussed in future work.
Originality/value
The authors propose an approach to dynamically selecting appropriate service‐oriented peers in a P2P network, where the composition of e‐services in a business process can be enhanced significantly. The approach is based on ontology and QoS perspectives, and the descriptions of services have rich semantic features in an attempt to make the service selection more intelligent and reliable. Therefore the proposal offers e‐service providers innovative initiatives to re‐engineer their business services.

Abstract
Purpose
The purpose of this paper is to identify information governance (IG) requirements in the context of dynamic business networking (BN).
Design/methodology/approach
For the identification of IG requirements a systematic literature review is conducted. The practical significance of identified IG requirements is evaluated through a case study.
Findings
A comprehensive list of IG requirements in dynamic BN is identified. These requirements are classified in information quality, information security, and metadata domains. The conducted case study demonstrates information exchange issues in a real world dynamic BN that reflects the practical significance of the identified IG requirements.
Research limitations/implications
Exploiting emerging market opportunities through a dynamic BN necessitates the realization of a comprehensive IG program within the network. Otherwise, information exchange related risks can interrupt the operations in a BN. In this research the authors concentrate on interactions between parties within a BN. The interactions with customers for the co-creation of value are not addressed directly. Although the conducted case study reflects the practical significance of the identified IG requirements clearly, more empirical study is needed for prioritizing these IG requirements.
Practical implications
The governor of a BN needs to balance between the value obtained from dynamic networked interactions and the risk evolving from the dynamic inter-organizational information exchange.
Originality/value
The comprehensive list of IG requirements that are identified in this research can be used to develop an IG program that enables high quality and secure information exchange in a dynamic BN.

Abstract
Purpose
The goal of the study is to underline “Cinematic Architecture” as another source of architectural thinking and research. This study is also a response to the shortage in empirical research on architecture in the cinema. Moreover, the study introduces the architectural components that qualify the cinematic spaces to be influential cinematic experience. This is in addition to investigating the impact of these components on the viewers' cognitive and emotional experience of films.
Design/methodology/approach
In the reported study, an empirical experiment examined scenes from three different movies as experienced by a selected group of audience of movies fans (architects and laypersons). The audience was asked to report feelings the audience had about each scene using a questionnaire that was designed for this purpose, and the audience was asked to write down the aspects that affected the audience's emotions. The experiment evaluated selected emotional states and could specify the architectural features and/or objects that significantly contributed in inducing these emotions.
Findings
This study's findings concluded that emotions, which exist in the positive margin of the emotions “circumplex model,” were influenced by architectural components that were different from those that influenced emotions which lie in the negative margin of the model.
Research limitations/implications
As for filmmakers, the study contributes in developing filmmakers' knowledge about the role of architecture in scenic creation and thus how that knowledge enhances filmmakers' film narrative and the narrative's spatial imagery. As for academia, this study contributes in developing the knowledge about film cognition as related to architectural semiotics. In the context of behavioral approach to architectural design, a behavior setting which is the basic element in environmental design can be dramatized by applying a cinematic narrative to a human activity system within a milieu of architectural design elements.
Practical implications
This study is important for architects, as the study provides architects with an alternative tool for fictional experience and for testing architectural ideas through cinematic architecture. This study also helps in developing new venues for the practice of architecture into the world of fiction. This study also contributes in developing the trend that architectural design thinking can learn from cinematic thinking and practice.
Originality/value
This study introduces an empirical approach to evaluate architectural entities as part of cinematic experience. This study also comes as a response to the shortage in empirical research on architecture in the cinema.

Abstract
Purpose
Service composition phenomenon based on non-scenario aspects are become the latest issues in enterprise software applications of the multi-cloud environment due to the phenomenal increase in a number of Web services. The traditional service composition patterns are hard to support the dynamic, flexible and autonomous service composition in the inter-cloud platform. To address this problem, this paper aims to describe a dynamic service composition framework (SCF) that is enriched with various structural and functional aspects of composition patterns in a cloud computing environment. The proposed methodology helps to integrate various heterogeneous cloud services dynamically to acquire an optimal and novel enterprise solution for delivering the service to the end-users automatically.
Design/methodology/approach
SCF and different composition patterns have been used to compose the services present in the inter-cloud architecture of the multi-agent-based system. Further, the proposed dynamic service composition algorithm is illustrated using a hybrid approach, where service are chosen according to various needs of quality of service parameters. Besides, a priority-based service scheduling algorithm is proposed that facilitates the automation of delivering cloud service optimally.
Findings
The proposed framework is capable of composing the heterogeneous service and facilitate the structural and functional aspects of service composition process in enterprise cloud-based applications in terms of flexibility, scalability, integrity and dynamicity of the cloud bus. The advantage of the proposed algorithm is that it helps to minimize the execution cost, processing time and get better success rate in delivering the service as per customer’s need.
Originality/value
The novelty of the proposed architecture coordinates cloud participants, automate service discovery pattern, reconfigure scheduled services and focus on aggregating a composite services in inter-cloud environments. Besides, the proposed framework supported several non-functional characteristics such as robustness, flexibility, dynamicity, scalability and reliability of the system.

Abstract
Purpose
Most of the existing studies on the evolution of emergency topics in social media focused on the emergency information demand of fixed user type in emergency while ignoring the changing roles of stakeholders during the emergency. Thus in this study, a three-dimensional dynamic topic evolution model is proposed, in which fine grained division of time, dynamic identification of stakeholders in the emergency, and emergency topic evolution based on both timeline and stakeholder's type are all considered.
Design/methodology/approach
Particularly the relevance between the tweets posted and the topic of emergency, the influence on the social network, and the attention of emergency topic are as well taken into account to quantitatively calculate the weight and ranking of stakeholders at different stages of the emergency. To verify the proposed model, an experimental demonstration was carried out under an emergency event posted on social media.
Findings
The results show that (1) based on the three-dimensional dynamic topic evolution model, the composition and ranking of stakeholders have obvious differences at different stages; (2) the emergency information needs and the sharing behavior of stakeholders on emergency information also indicate different preferences where the topic concerns of stakeholders at different stages have a strong relationship with their weight ranking; (3) the emergency topic evolution considering both the dynamics of emergency stakeholders and emergency information demand could more accurately reflect the changing regularity of social media users' attention to information in emergency events.
Originality/value
This study is one of first to investigate the emergency topic evaluation on social media by considering the dynamic changes of various stakeholders in emergency. It could not only theoretically provide more accurate method to understand how users share and search emergency information in social media, but also practically signify an information recommendation way in social media for emergency tracking.
