Paper Title: Analyzing Processes behind Web Service Standards Development

Abstract:
Anticipatory standards such as Web service standards are artifacts ‘designed’ by consortium-based standards development organizations. Intricate processes followed to develop anticipatory standards are not well-understood. Recently, the D-S-N model was developed to explain these processes, and suggested that these processes contain cycles of design (D), sense-making (S), and negotiation (N) activities. In this paper, we provide an initial report of a case study that empirically analyzes archival documents of SOAP standard development. Our findings reveal that the D-S-N model is applicable to the Web service standardization process followed at W3C but this model provides only partial explanation of the process, and that design and sense-making are the core activities of the process. Our findings also show that participants spent most of their time discussing technical issues and identifying action items to be performed, large organizations dominated the process, and negotiation is the least frequent activity.

Paper Title: An Investigation of W3C Standardization Processes Using Rational Discourse

Abstract:
Standards, in particular Web standards, have become critical and complex information technologies as they influence our everyday activities. Standards making is a social practice where in experts engage in discussions to develop standards by weighing various alternative design solutions. Processes followed to develop these standards and how decisions for core features are made is not well understood. In this paper, we drawn on concepts of rational discourse described by Habermas to examine whether processes followed at W3C meets requirements of rational discourse. Our investigation shows that processes followed at W3C do exhibit an approximation of rational discourse, while some concerns exist.

Paper Title: Factors that Persuade and Deter Membership in Professional Computing Associations

Abstract:
A decision to join a professional computing association is, generally, considered a decision to affiliate with a group. The value of a professional association can be measured in terms of services it offers. Professional computing associations play a critical role in advancing professional growth of its members by offering a variety of services such as career development, networking opportunities, and dissemination on current advancements in the profession. In particular, the computing discipline consists of several sub-disciplines each having substantial differences among them, which creates considerable differences among computing professionals. Due to differences among computing professionals, it is important for computing professional associations to identify services that are valuable for its members and help in retaining their membership. Towards that, in this paper, we identify factors that persuade and deter membership in professional computing associations. We present results of a survey conducted with the Association of Information Technology Professionals’ members, with primary focus on qualitative analysis of responses to open-ended questions. Persuading factors identified are networking opportunities, dissemination of technical information and advancement in the field, professional development programs, advocacy opportunities, leadership and community service opportunities, and reputation of the association. Deterring factors are solicitation and unwarranted emails, timing and location constraints of events, lack of a local chapter, and behavior and characteristics of peer members in the association.

Paper Title: Role of Web Server in Capstone Course

Abstract:
Web applications has become commonplace in the information systems curriculum. Much of the discussion about Web development for capstone courses has centered on the scripting tools. Very little has been discussed about different ways of incorporating Web server into Web application development courses. In this paper, three different ways of incorporating Web server are discussed: shared Web server (minimal student control), managed Web server (configuration control), and controlled Web server (full student control). This paper argues that capstone courses oriented towards Web applications development should provide certain amount of Web server control to students as it is an important skill set to acquire.

Paper Title:From Service Conversation Models to WS-CDL

Abstract: Changing business environments are forcing organizations to develop flexible and adaptable enterprise systems. To accomplish this and to solve associated systems integration issues, many are moving towards web service technology. Two key ingredients of web services based solution are service composition and service choreography. While there has been lot of advancement in respect to service composition, service choreography rather largely remains an open problem. WS-CDL specification is considered to be a candidate standard for service choreography; however, consensus on support mechanisms to develop conversation models depicting peer-to-peer interactions are yet to be reached. In this paper, we develop an approach as well required heuristics for identifying service interaction patterns from business process models and using them to develop conversation models. We provide detailed discussion on heuristics, illustrate our approach through an example, as well as indicate how these conversation models can be used for generating WS-CDL specifications.

Paper Title: Information Extraction From Different Data Representation Forms: Charts and Tables

Abstract:
Presenting data in the form of graphs and tables has long been considered as an important tool for decision making. Extracting information from these presentation forms are considered to be cognitively intensive tasks. Prior research works on aspects of presentation forms have produced inconsistent and conflicting results. In this study, we examine effects of tabular and graphical (bar, line, and pie) forms on information extraction. Graphs were examined with solid and textured patterns as well. We conducted a laboratory experiment where in subjects answered set of questions which would require them to extract information from the presentation display. Our study reveals that tables, even though they have higher response rate, produced more accurate results than graphs. Comparison within graphs showed that bar charts had a lower response rate than pie and line charts, while pie charts produced the least accurate results. Comparison of solid and textured patterns in graphs revealed that they are not an influencing factor in regards to information extraction. We also provide detailed comparison of current research findings against to prior research results.

Position Paper accepted for publication at the ONISW 2008

noreply@blogger.com (Karthikeyan Umapathy) — Tue, 09 Sep 2008 14:06:00 +0000

Position paper titled "Toward Generic, Immersive, and Collaborative Solutions to the Data Interoperability Problem which Target End-Users" is accepted for publication in the 2nd International workshop on Ontologies and Information Systems for the Semantic Web (ONISW 2008) to held along with the ACM 17th Conference on Information and Knowledge Management in Napa Valley Marriott Hotel & Spa: Napa Valley, California, October 26-30, 2008.

Authors: Arturo J. Sánchez-Ruíz, Karthikeyan Umapathy, and Pat Hayes

Abstract:
In this position paper we describe our vision of a “just-in-time” approach to the Data Interoperability Problem (a.k.a.INTEROP.) It empowers data stakeholders (e.g. data producers and data consumers) with integrated tools to interact and collaborate with each other while directly manipulating visual representations of their data in an immersive environment
(e.g. implemented via Second Life.) The semantics of these visual representations and the operations associated with the data are supported by ontologies defined using the Common Logic Framework (CL). Data operations gestured by the stakeholders, through their avatars, are translated to a variety of generated resources such as multi-language source code, visualizations, web pages, and web services. The generality of the approach is supported by a plug-in architecture which allows expert users to customize tasks such as data admission, data manipulation in the immersive world, and automatic generation of resources. This approach is designed with a mindset aimed at enabling stakeholders from diverse domains to exchange data and generate new knowledge.

Review of Language-Action Perspective (LAP)

noreply@blogger.com (Karthikeyan Umapathy) — Sat, 30 Aug 2008 21:35:00 +0000

Book chapter titled "A Review of the Language-Action Perspective (LAP) Approach in Information Systems Research" is accepted to be published as a book chapter in Handbook of Research on Contemporary Theoretical Models in Information Systems.

ABSTRACT

The Language-Action Perspective (LAP) provides an alternative foundation for analyzing and designing effective information systems. The fundamental principle of the LAP approach is people perform actions through communication; therefore, the role of information systems is to support such communications among people to achieve business goals. Basing on linguistic and communicative theories, the LAP approach provides guidance for researchers to gain understanding on how people use communication to coordinate their activities to achieve common goal. Web services, a leading technology to develop information systems, aims to support communication among services to achieve business goals. The close match between fundamental principles of web services and the LAP approach suggests that researchers can use the LAP approach as a theoretical guidance to analyze and resolve web service problems. This chapter provides a comprehensive starting point for researchers, practitioners, and students to gain understanding of the LAP approach.

Paper Title: Standardizing Web Services: Overcoming ‘Design by Committee’

Abstract:
Web service standards, like several other IT standards, are anticipatory, i.e., they are designed and codified in anticipation of actual adoption and use. As a result, the setting of web service standards takes on properties that resemble the designing of software artifacts. In contrast, the traditional perspective on standards views them as law-like systems that legislate modes of
behavior, product structures or specifications. The two perspectives – ‘design’ and ‘legislation’ – can sometimes be at odds. In the software engineering community, the phrase ‘design by committee’ has come to symbolize designs that are not effective, not elegant and not addressing issues that are core to the original intentions. Current efforts and recent outcomes in web
services standards appear to have overcome this taboo. We demonstrate, with the help of an empirical study, how the participants interact, and the roles they take on to produce web service standards.

Paper Title:
Representing and Accessing Design Knowledge for Service Integration

Abstract:
Process construction from existing services requires use of appropriate design knowledge. For services that are mapped to underlying legacy applications, this takes the form of enterprise integration solutions. Design knowledge in this domain is available in the form of Enterprise Integration Patterns (EIP). These patterns are, however, difficult to understand; they also use primitives that are different from those used for process representation. As a result, accessing EIP based on process requirements remains a cognitively demanding task for designers. In this paper, we describe a knowledge-base that represents the EIPs, infusing them with semantics derived from speech acts; and a set of heuristics, which can be used to retrieve EIPs for a set of requirements. An example serves to illustrate how the two can work in tandem to assist the designer.

Paper Title: Designing Enterprise Integration Solutions - Effectively

Abstract: The design of large and complex enterprise integration solutions is a difficult task because designers must respond not only to the ‘requirements’ from a diverse set of users, but also because a successful design outcome must respond to the ‘constraints’ provided by the current set of legacy applications. The problem, therefore, belongs to a category of problems where design knowledge is difficult to articulate and reuse. In particular, the nature and form of knowledge for conceptual design of systems integration solutions continues to be a concern. In this paper, we investigate whether design knowledge in the form of patterns can be reused to develop systems integration solutions, and whether such reuse leads to more effective design outcomes. The research follows Design Science guidelines in that we describe a research artifact, and evaluate it to assess whether it meets the intended goals. The results indicate that approaches to facilitate reuse of conceptual design knowledge are feasible in the domain of enterprise integration, and that such reuse does, in fact, lead to more effective design solutions.

When Requirements Go Bad: Requirements Errors

noreply@blogger.com (Karthikeyan Umapathy) — Wed, 09 Jan 2008 19:12:00 +0000

Yesterday I attended a talk on “When Requirements Go Bad: Requirements Errors - Sources and Avoidance Strategies” by Kurt Bittner. Kurt Bittner has co-authored two books: Managing Iterative Software Development Projects and Use Case Modeling.

Kurt Bittner Bio on InformIT
http://www.informit.com/authors/bio.aspx?a=4B75C773-9B16-4283-88F9-888B641A7058&rl=1

He categorized requirements errors into three categories
1. Misconception errors – user needs misconstrued
2. Specification errors – user needs understood but written ambiguously
3. Implementation errors – communication breakdowns and lack of enough reviews and testing

While above were the core of the talk, he also provided some typical errors and strategies to avoid them. The entire talk was excellent and worth the money, given that I am teaching a requirements management course this spring.

Paper Title: Exploring Alternatives for Representing and Accessing Design Knowledge about Enterprise Integration

Abstract: Enterprise integration refers to solutions that facilitate meaningful interactions among heterogeneous legacy applications. The scale, complexity and specificity of most enterprise integration efforts mean that design knowledge for enterprise integration has resisted codification. Important exceptions to this include: use of Business Process Modeling (BPM) techniques to understand integration requirements; and Enterprise Integration Patterns (EIP), which present designers with abstract descriptions of recurring design tactics for integrating applications. The two, however, can be at odds. BPM encourages the control flow perspective; whereas EIP codifies an operational perspective. Mapping between the two to develop coherent solutions, therefore, tends to be problematic. To bridge the gap, we suggest an alternative that builds on the theory of speech acts. We develop essential components of such an alternative, including a re-representation of EIP as structures of speech acts, a characterization of tasks in BPM with action types, and a mapping between speech acts and action types. The components are accompanied by inference rules that produce a mapping between sets of tasks in a business process, and structures of speech acts as integration patterns. Through a short industry case, we demonstrate usefulness of the proposed alternative.

Paper Title:
A Study of Language-Action Perspective as a Theoretical Framework for Web Services

Abstract
This dissertation contributes to the services science discipline by examining appropriateness of Language-Action Perspective (LAP) as a theoretical framework for web services, the technology component of services science. This research consists of three inter-dependent studies. The first study (completed) investigates whether LAP constructs can describe and explain the web services architecture. Findings from this study indicate that there is a lack of mechanisms to generate conversation specifications that guide interactions among services. Conversation specifications are crucial for developing large-scaled enterprise integration solutions using web services. The second study (work-in-progress) builds on this finding and demonstrates the appropriateness of LAP constructs to access design knowledge to develop web service solutions for enterprise integration. The third study (work-in-progress) evaluates the usefulness of LAP constructs to develop effective web service solutions (artifact developed in the second study).

Paper Title:
Towards A Theoretical Foundation for Web Services – The Language-Action Perspective (LAP) Approach

Abstract:
The purpose of this paper is to stimulate a discourse and search for appropriate theoretical foundations for web services. The complexity of web services technology demands such a foundation. A theoretical foundation can provide adequate guidance not only to accelerate research related to web services, but can also promote their acceptance. Based on an extensive review of prior work in SCC and ICWS, we identify theories implicitly used for web services research, and propose the Language-Action Perspective (LAP) as an important and necessary complement to these. Our proposal follows the observation that there is a close match between the core concerns of web services and the LAP approach. Our ongoing work is aimed at validating appropriateness of LAP as a theoretical framework for web services through empirical research.

Title of the paper:
A theoretical investigation of the emerging standards for web services

Abstract:
Currently, standards for web services are being developed via three different initiatives (W3C, Semantic web services and ebXML). To the best of our knowledge, no theoretical perspectives underlie these standardization efforts. Without the benefit of a strong theoretical basis, the results, within and across these initiatives, have remained piecemeal. We suggest ‘Language–Action Theories’ as a plausible perspective that can effectively define, assess and refine web services standards. In this paper, we first investigate the existing initiatives to identify commonalities that point to theories of ‘Language–Action’ as an appropriate theoretical basis for web services standards. Next, we adapt work from these theories to develop a comprehensive reference framework for understanding web services standards. Finally, we use this reference framework to assess the three initiatives, and analyze the findings to provide insights for future development and refinement of web services standards.
