Description
Interactive Knowledge is an integrating project targeted
at the hundreds of SMEs in Europe, which are providing technology platforms for content and knowledge management to thousands of end user organisations. Downstream, hundred-thousands of corporate end users and millions of content consumers are affected by the quality of service provided through these platforms. The majority of these platforms lack the capability for making use of semantic web enabled, intelligent content, and therefore, lack the capacity for users to interact with the content at the user‘s knowledge level!

The major technological result of the project will be the "Interactive Knowledge Stack", a layered set of software components and specifications which will make traditional content management platforms capable of dealing with the future "Semantic Web".

    Public Deliverable - The objective of this deliverable is to design a benchmark model for Content Management Systems (CMSs) in order to identify relevant requirements for the Interactive Knowledge Stack (IKS). The IKS will be a layered set of software components and specifications with the goal to improve the interaction with knowledge objects of CMSs by using Semantic Web technologies. In contrast to projects that benchmarked rather technical aspects of CMSs, we propose a model that evaluates CMSs consistently from the business perspective down to the technology layer. This approach is based on IT alignment theory that states that higher degrees of fit between business needs and IT result in increased business performance. Accordingly, IT executives of organizations that provide CMSs and IT executives of organizations that use CMSs as well as CMS developers are taken into account covering both business and technical aspects. The deliverable is structured as follows. First, we introduce the IKS project and pose relevant research questions that the IKS benchmark model for CMSs must address. Then, related work on CMS benchmarks, semantic technologies and applications is discussed from which shortcomings of exiting benchmarks are derived and implications for the design of the IKS benchmark model are drawn. Afterwards, we present the IKS benchmark model for CMSs, which describes a study-driven and experiment-driven approach to compare CMSs. Consistent with the model, questionnaire items for the study targeted at IT executives of CMS customer and provider organizations and implementation tasks for the experiment targeted at CMS developers are provided. Finally, we conclude this deliverable by a summary and an outlook on the next steps within the IKS project.

    The intelligent bathroom use case represents a "far out" vision of IKS for direct user interac- tions with embedded contents that are organized by a "Semantic CMS Technology Stack". This case combines advanced content and knowledge management with an ubiquitous com- puting scenario in a place everybody is familiar with - the bathroom. The use case shows how users can interact with contents in physical environments in a way that leaves the di- mension of "small windows to the info sphere" as known by the "monitor paradigm" (Janzen et al., 2010). The objective of D4.1 is to provide guidance for the design, implementation and evaluation of such interactive knowledge-supported ubiquitous environments. In D2.1 (Janzen et al., 2010), a Situational Design Methodology for Information Systems (SiDIS, formerly known as CoDesA) (Maass & Janzen, 2011) was introduced and results from first four tasks of that methodology were presented. In this deliverable, tasks 5 to 8 are applied. Therefore, key re- search challenges for the AmI case will be identified and supported by related work. One of these challenges is the development of a knowledge representation for highly dynamic envi- ronments. So, we started with the conceptual design of such a knowledge representation for the AmI use case; the approach consisting of a contextual and situational part will be intro- duced. We will present our procedure in designing and modelling the knowledge representa- tion by means of Ontology Design Patterns (Gangemi, 2005; Gangemi & Presutti, 2009) that are provided by IKS and that are combined with conceptual models based on SiDIS. Fur- thermore, the development of a logical as well as technical architecture for the AmI case is elaborated. Afterwards, we will focus on the implementation of the technical architecture of the system, especially on the presentation of contents in the bathroom based on the seman- tic knowledge representation. Next, the results of the empirical evaluation of the resulting software integrated in the physical bathroom environment will be presented. Furthermore, the results of the re-iteration phase in T4.1 will be shown, validating the Beta version of IKS in the context of the real-time bathroom environment. D4.1 will be closed by a discussion of ex- periences and lessons learned when developing interactive knowledge-supported ubiquitous information systems by means of IKS.

    The Use of Free and Paid Digital Product Reviews on Mobile Devices in In-Store Purchase Situations
    (Athens University of Economics & Business, 2009-09-27)

    Digital product reviews provided by users and experts are used as purchase decision cues. In contrast to reviews obtained by websites on the desktop, it is open if they are adopted in in-store purchase situations on mobile devices. In addition, it is an open issue to which degree free digital product reviews provided by users or paid digital product reviews provided by experts are adopted and influence consumers' preferences for stores that offer access to them. To answer these questions, a theoretical model is proposed based on Innovation Diffusion Theory (IDT), Technology Acceptance Model (TAM) and Theory of Planned Behaviour (TPB). Then, the model is empirically evaluated by conducting a study with 116 subjects. Analysis of variance (ANOVA), one-sample t-tests and Pearson correlation coefficients are used to examine the data. Results indicate that digital product reviews are adopted on mobile devices in in-store purchase situations, especially when they are provided for free and refer to consumer electronics. On average, consumers are willing to pay 2.9 percent of the product's price for a corresponding review. Based on these findings, new business models for providers of reviews and store managers are conceivable that extend physical products with free or paid digital content through the use of product identification technologies at the point of sale.

    IKS Deliverable - D6.4: End User Perception of Semantic CMS Applications

    Public EU Deliverable of the IKS project - This deliverable develops and tests a user-oriented content-support acceptance model (CSAM) which helps to better understand the phenomena of content service adoption. Additional, it provides recommendations on how to improve existing IKS-related content services. In this regard, a literature review on adoption constructs is conducted from which then CSAM is developed. The major advantage of CSAM is its flexibility to incorporate various empirical constructs and dimensions such as content service characteristics (e.g. interactivity, relevancy, perceived ease of use), service utility (e.g. perceived usefulness) or service utilization (e.g. likeliness of reuse) that can be particularly applied to the evaluation of concrete CMS applications. This flexibility will be shown in this report by applying CSAM to a traditional CMS application in a business situation (i.e. the IKS Tourism use case) as well as to a ubiquitous CMS application in a private situation (i.e. the IKS AmI use case). Results show, that CSAM is supported by the empirical data and that informed decision can be derived for a revision of existing IKS-related content services.

    Public EU Deliverable of the IKS project - This report provides an evaluation of the impact that IKS and its related projects had on the CMS community. Impact metrics have been selected from online analytics tools (i.e. website visits, unique visitors, page views, page views per visit, average visit duration, bounce rate and percentage of new visits) as well as EU assessment guidelines, feedback from the third EU review meeting and Information Systems research (i.e. technology impact, business impact, research impact, educational impact, impact on CMS community, sustainability of project results and on going activities beyond 2012, benefits of semantic-enhanced CMS). Data used for this impact evaluation was taken from online access to websites relevant to IKS and the IKS Impact Assessment Survey 2012 conducted at the end of 2012. Results indicate that IKS and its related projects have generated almost 360 000 page views over the course of the last six months in 2012. This together with the graduation of Apache Stanbol from its incubator status in 2012 can be interpreted as a remarkable impact of the project. Moreover, results of the IKS Impact Assessment Survey 2012 indicate that the combination of semantic technologies and CMS are able to provide several benefits such that semantic-enhanced CMS are recommended to a high degree. Additionally, technological impact, business impact and educational impact of IKS results are rated at a notable degree, too. All in all, it can be therefore concluded that IKS was a successful EU project.

    Confidential Deliverable - The objective of this deliverable is to provide requirements for the development of knowledge-based interaction with Content Management Systems (CMS) and to identify interaction patterns for the communication between users and systems as well as between system components on different devices. Furthermore, we present a formal description of a model of content-oriented interaction. In order to consolidate the requirements, we had brainstorming discussions with the industrial partners to refine requirements that were extracted beforehand from selected publications and reports. Furthermore, studies from standardization consortia, active in the field of semantic interaction have been taken into account.

    Confidential Deliverable - The objective of this deliverable is to describe the results of the exercise which is executed to benchmark the industrial software capabilities as one aspect of the requirements capturing process for the Interactive Knowledge Stack. The theoretical foundation and the underlying model which are used for the benchmarking approach have been designed in (Kowatsch et al. 2009, IKS D1.1 Design of the Semantic Benchmark Experiment). Combining business-driven requirements and technical aspects the benchmark model provides a two-fold approach addressing IT executives of CMS providers and customers on the one hand and CMS developers and architects on the other hand. The experiment includes interviews and development tasks ("semantic challenges") to evaluate business needs and technological capabilities.

    Confidential Deliverable - Deliverable 1.3 of the IKS Project is a non-public report describing in some detail, the results of the following research activities: 1. An empirical study concerning perceived business needs in relation with content management. This study generated more than 170 individual statements of needs and was based on a survey done with two populations: (a) senior executives from CMS technology providers and (b) senior executives from CMS user organisations. 2. The detailed qualitative analysis of an experiment in which six CMS technology providers had been asked to 3. (a) develop prototype solutions for seven "semantically rich" CMS tasks and where they were subsequently asked to (b) provide a self assessment of their current ability to provide the above semantically rich services to customers. A detailed comparison of 12 high level business needs as perceived by: (a) CMS technology providers (based on the above empirical study) (b) CMS customer organisations (based on the above empirical study) (c) CMS intermediaries and consultants (using their benchmarking criteria) (d) Researchers into CMS and Semantic technologies (based on the semantically rich CMS tasks and their implicit rating of technical difficulty). The tangible outcomes of the work presented here are the 170+ business needs, ranked and prioritized according to stakeholder's opinions and aggregated into 12 high level requirements. In addition, the document provides a basis for aligning and harmonising various exist- ing benchmarking methods and criteria lists for assessing CMS technology. By linking benchmark criteria to business needs, the report makes an important contribution to the field of IT Alignment, specifically for advanced content management applications.

    Public EU Deliverable of the IKS project - On this report, results of IKS Task 6.2 "Validation of IKS through industrial use case application developers" are reported. The overall objective of this task is described in the Description of Work (p. 76) as follows: "To produce a robust and scalable architecture, the reference implementation of the Interactive Knowledge Stack will be tested through large scale real life field studies. In order to guarantee that an industry-strength Semantic CMS Stack is created, the IKS components will be tested and validated through industrial use case applications. The use cases will be selected among the ones which can be operated by knowledge workers with clear organizational needs and goals but without sophisticated knowledge of advanced formalisms or technologies."
