This paper argues that the ongoing debate around which of these paradigms is better suited to undertake IS research has created confusion amongst IS researchers, particularly between those who are relatively inexperienced (e.g. PhD researchers). Inexperienced researchers tend to place emphasis on the justification of their research approaches in the context of existing paradigms without offering a clear description of how the chosen methods and paradigms are applied in the context of their own research, a key issue to assess and understand any research output. This paper does not attempt to give any suggestions as to which research methods/paradigms should be used for IS research, but to raise the awareness that the way we currently communicate our thoughts in the research methods domain may not be very effective. We argue that an initial step to undertake this challenge could be to take a more "practical" approach by focusing on the process of thinking and planning the research activity rather than focusing on the justification of the use of one or many research methods usually "loaned" from other disciplines.

As a result, several researchers have investigated the means of improving the business/IT relationship. They focus on behaviors of business and IT groups and attempt to develop change management programs as a vehicle for obtaining desired behaviors from business and IT groups in order to improve the ' relationship'. However research shows that such attempts have a low success rate in attaining an effective ' relationship'. This paper argues that the reason for this is that most researchers tend to focus on behaviors of people without an in-depth understanding of their cognition, which influences those behaviors. Consequently the paper proposes a cognitive approach and explores the application of Personal Construct Theory (PCT) to understand the ' relationship' and means to improve it.

Therefore, this article aims to critically survey the existing literature in order to assess the kind of research that has been performed over the years, analyze the nature of the research contributions and establish its current state of the art by positioning, evaluating and interpreting relevant research to date that is related to ODCM. To understand and identify any gaps and research opportunities, our literature study is composed of both a systematic mapping study and a systematic review study. The mapping study aims at structuring and classifying the area that is being investigated in order to give a general overview of the research that has been performed in the field. A review study on the other hand is a more thorough and rigorous inquiry and provides recommendations based on the strength of the found evidence. Our results indicate that there are several research gaps that should be addressed and we further composed several research opportunities that are possible areas for future research.

Expert representatives of major foundational ontologies have been invited to discuss and compare their meta-ontological choices within the context of a common case study. The workshop is aimed at exploring the ways in which different meta- ontological choices impact conceptual modelling in information systems.

However, as the closed-worlds of ES are opened to Internet scale data sources, there is an emerging need to better understand the semantics of such data and how they can be integrated. Foundational ontologies can help establish this understanding and therefore, there is a need to investigate how such ontologies can be applied to underpin practical ES integration solutions. This paper describes research undertaken to assess the effectiveness of such an approach through the development and application of the 4D-Semantic Extract Transform Load (4D-SETL) framework. 4D-SETL was employed to integrate a number of large scale datasets and to persist the resultant ontology within a prototype warehouse based on a graph database. The advantages of the approach included the ability to combine foundational, domain and instance level ontological objects within a single coherent system. Furthermore, the approach provided a clear means of establishing and maintaining the identity of domain objects as their constituent spatiotemporal parts unfolded over time, enabling process and static data to be combined within a single model.

Web services provide the means to modularize software in a way that functionality can be described, discovered and deployed in a platform independent manner over a network (e.g., intranets, extranets and the Internet). The representation of web services by current industrial practice is predominantly syntactic in nature lacking the fundamental semantic underpinnings required to fulfill the goals of the emerging Semantic Web. This paper proposes a framework aimed at (1) modeling the semantics of syntactically defined web services through a process of interpretation, (2) scoping the derived concepts within domain ontologies, and (3) harmonizing the semantic web services with the domain ontologies. The framework was validated through its application to web services developed for a large financial system. The worked example presented in this paper is extracted from the semantic modeling of these financial web services.

This paper combines text-mining, feature selection and Bayesian Networks to analyze and extract sentiments from stock-related micro-blogging messages called "StockTwits". Here, we investigate whether the power of the collective sentiments of StockTwits might be predicted and how these predicted sentiments might help investors and their peers to make profitable investment decisions in the stock market. Specifically, we build Bayesian Networks from terms identified in the tweets that are selected using wrapper feature selection. We then used textual visualization to provide a better understanding of the predicted relationships among sentiments and their related features.

Grid services have come to represent the synthesis of web services and grid computing paradigms. ... more Grid services have come to represent the synthesis of web services and grid computing paradigms. Web services provide the means to modularize software, enabling loosely coupled and novel synthesis. Grid computing removes the binding between functional software components and specific hosting hardware, enabling software to be deployed dynamically over a network (e.g. intra-, extra-or inter-net). Applying the constructs of grid computing to the service orientation of enterprise software will allow business service networks to utilize more specialized services. An upper service ontology that enables business grid services to be described and then related to the grid hosting platform is presented. Explicit knowledge is required for enterprise software, hosting servers and the domain that can then be utilized by both SLA and reservation systems. The ontology presented is derived from and validated using a collection of web services taken from leading investment banks.

Folksonomies, a Web 2.0 technology, represent such an example. Folksonomies result from individuals freely tagging resources available to them on a computer network. In a library environment folksonomies have the potential of overcoming certain limitations of traditional classification systems such as the Library of Congress Subject Headings (LCSH). Typical limitations of this type of classification systems include, for example, the rigidity of the underlying taxonomical structures and the difficulty of introducing change in the categories. Folksonomies represent a supporting technology to existing classification systems helping to describe library resources more flexibly, dynamically and openly. As a review of the current literature shows, the adoption of folksonomies in libraries is novel and limited research has been carried out in the area. This paper presents research into the adoption of folksonomies for a University library. A Web 2.0 system was developed, based on the requirements collected from library stakeholders, and integrated with the existing library computer system. An evaluation of the work was carried out in the form of a survey in order to understand the possible reactions of users to folksonomies as well as the effects on their behavior. The broad conclusion of this work is that folksonomies seem to have a beneficial effect on users' involvement as active library participants as well as encourage users to browse the catalogue in more depth.
