Conference Theme:
Cognitive Computing and Data-Driven Business

i-KNOW 2015 aims at advancing research at the intersection of disciplines such as knowledge discovery, semantics, information visualization, visual analytics, social (semantic) and ubiquitous computing. The goal of integrating these approaches is to create cognitive computing systems that will interact naturally with humans, learn from their experiences and generate and evaluate evidence-based hypotheses. That is, we interpret cognitive computing as the convergence of various knowledge technologies research fields. On the other hand, data-driven business represents the business perspective on cognitive computing and takes application specific knowledge (such as semantics) into account.

We are specifically interested in the integration of data-centric and user-centric approaches and welcome contributions from both ends of the spectrum.

Topics of the Main Conference Track include
(but are not limited to):

Knowledge Discovery & Data Analytics

The growing popularity of big data fostered a new type of researcher, the data scientist. Typical responsibilities of this role are associated with the area of knowledge discovery and data analytics. Algorithmic approaches often focus on machine learning, information retrieval and for textual data on natural language processing. In this call for paper we therefore invite all data scientists to submit your exciting work in the area of knowledge discovery and data analytics.

Special Tracks „15 Years i-KNOW“:
From Knowledge Management to Data-driven Business

The i-KNOW conference is celebrating its 15th anniversary! We think this is a great opportunity to reflect how research in the area of Knowledge Management and Knowledge Technologies has changed and developed further as a reaction to new challenges and opportunities.

For this purpose, you are invited to contribute submissions for the i-KNOW anniversary special track series. All tracks have in common that they combine a look at the past with an outlook into future developments. We are delighted to have engaged renowned experts to chair our special track series focusing on the following topics:

Industry 4.0: educating the workforce for smart industries

Chairs: Martin Wolpers, Ralf Klamma

The introduction of smart factories, internet of things and cyber-physical systems (in Germany coined „Industry 4.0“) changes the industrial manufacturing and production workplaces dramatically.
Companies and employees are faced with new requirements regarding the workplace. It is questionable if existing pedagogical and technological concepts address the new emands on the workforce sufficiently and adequately. Today, and in spite of political wishes, industry 4.0 related workplaces are still at the verge of emergence.

This track aims to foster discussions on new learning and training challenges in smart industries where products will „know“ the workforce. Papers are invited that discuss Industry
4.0 related learning scenarios and how they are being addressed.

Topics of interest include, but are not limited to, the following:

  • Collaborative learning
  • Micro-format learning
  • Just-in-time learning
  • Education with/cyber-physical systems
  • Wearables for learning purposes
  • Smart factory learning scenarios
  • Personalization and adaptation
  • Recommendation
  • Learning resource creation and management

Social Knowledge Management: from collections of documents to connections of people and physical objects

Chairs: Ronald Maier, Andreas Schmidt

Although knowledge has always been considered as inherently situated in the heads of people, knowledge management has started out with a technocratic focus on representations of knowledge in documents. The manifold developments of knowledge management since then include aspects of semantics and ontologies, activities and processes, assessment and evaluation, integration and visualization and a focus on the dynamics of knowledge maturing from emergent knowledge created by individuals to standardized knowledge applied by societies at large. With the advent of social software and the recent developments in networking of physical objects, knowledge management has shifted its attention more recently to collaboration and social relationships in collectives of people, from small teams to large crowds, termed social knowledge management, as well as to the inclusion of representations of and the interaction with physical objects, termed the Internet of things.

We solicit submissions that address the following topics:

  • Knowledge creation and knowledge maturing – from teams to crowds
  • Social collaboration, social networks, social spaces
  • Boundary spanning and the boundaryless organization
  • Connectivity in teams and organizations
  • Role of physical objects in knowledge management
  • Motivational aspects of social knowledge management

Dynamic Capabilities: from knowledge management to continuous organizational change

Chair: Barbara Kump

In increasingly dynamic operating environments, organizations not only have to manage and distribute their strategically relevant knowledge, but they are facing the need for continuous organizational learning and change, in order to remain competitive. Therefore, organizations need to develop certain strategic change capabilities, which all build on organizational knowledge processes. Organizational change capabilities include (i) organizational capabilities to search the environment (e.g., customer needs, technological innovations…), (ii) organizational capabilities to reflect upon existing practices (e.g., inefficient processes or structures), (iii) organizational capabilities to develop and share ideas for business opportunities (e.g., through innovation, absorption), and (iv) organizational capabilities to implement planned changes (e.g., by training their workforce, establishing effective communication structures). While large firms often build such capabilities by establishing dedicated divisions for market research and organization development, small and medium-sized enterprises (SMEs) usually cannot afford such divisions. Novel technologies, such as search and recommendation technologies, sensor technologies, or informal learning technologies, bear great potential to support organizations in general, and SMEs in particular, with developing organizational change capabilities.

This track invites both conceptual and empirical contributions around the question of how novel technologies can support organizational learning and change processes.
Topics of interest include, but are not limited to, the following:

  • Concepts for supporting organizational learning, continuous change, or the development of dynamic capabilities
  • Search and retrieval technologies to track customer needs, market trends etc.
  • Technologies which support reflection/reflective learning and changes in organizational processes and routines
  • Technologies which support the development of ideas for business opportunities
  • Technologies which support change communication
  • Technologies which support learning at work, especially with regard to planned changes

Augmented Reality: from visual assistants to always-on multimodal knowledge access

Chairs: Dieter Schmalstieg, Denis Kalkofen and Eduardo Veas

Technological innovations continuously transform the way we reach for and use knowledge. With augmented reality (AR), interfaces are associated with physical objects and the physical world turns into a user interface, which results in extended possibilities to naturally interact with complex systems. This workshop concentrates on how novel presentation metaphors in AR change the way we experience digital augmentations in the context of the real world for a more immersive, human acceptable experience. The goal is to explore novel techniques that make the perception of AR a more human experience, that foster continuous use without hindering the activities of the user, that put knowledge within reach, so that users, while accessing, gathering, consuming digital knowledge, are not required to interrupt their activities.

We welcome work in progress and contributions on the following general topics:

  • novel visualization metaphors in practice,
  • new unique interfaces and display devices that transform our perception of AR,
  • new multimodal experiences of augmentation (auditory, olfactory, haptics),
  • studies and evaluations of long term use of AR,
  • usability evaluations of AR applications and technology.

The workshop will increase awareness of the state-of-the art in augmented reality as an interface that can be used continuously, as well as open new avenues of research in multimodal interfaces for a more immersive AR experience.

Interactive Data Analysis: from InfoVis and SciVis to visual analytics in Big Data

Chairs: Jörn Kohlhammer, Tobias Schreck and Vedran Sabol

Over the past few decades, the fields of Information Visualisation and Scientific Visualisation have gone a long way in devising how data and information are presented to and interacted with by humans. A variety of general-purpose visualisation applications, such as Spotfire or Tableau, have emerged on the market bringing visualisation to the masses and, in connection with data analytics back-ends, transforming the way people view, explore and analyse data.
This i-Know Special Track invites scientists and practitioners to discuss theoretical and practical aspects of Visual Analytics, explore recent developments, and investigate trends from the following three perspectives: (i) reflecting on the achievements of traditional InfoVis and SciVis approaches and pointing out the advantages arising from advancing them to full-fledged Visual Analytics methods; (ii) reporting on latest results and advancements in Visual Analytics techniques, and on benefits arising from their practical applications; (iii) debating upcoming trends in Visual Analytics and the impact of related hot topics such as augmented reality, mobile computing and big data analytics.

We welcome novel contributions, surveys and work in progress on Visual Analytics including, but not limited to, the following topics:

  • From user-configured charts and algorithms to adaptive, personalised, context-sensitive visual analytics

    • Conveying data quality, accuracy and trustworthiness

Advances in Information Retrieval: from boolean retrieval to knowledge discovery and Big Data

Chairs: Michael Granitzer, Benno Stein

The field of Information Retrieval (IR) shaped the last decade on how humans search and work with information. Global players such as Google demonstrate the enormous impact of retrieval technology on the society its use of information. With the I-Know Special Track on „From Boolean Retrieval to Knowledge Discovery and Big Data“ we want to reflect the achievements in Information Retrieval in terms of research and industrial uptake. We aim to analyse their impact and influence on today’s world and probably extrapolate upcoming trends. We invite researchers to contribute by submitting research papers analysing past developments and an outlook on how they might impact future trends. Following the IR methodology, contributions should be based on a thorough analysis of particular sub-fields in Information Retrieval in terms of already published research or empirical analyses. See the following examples for possible topics to get an idea of a special and interesting contribution that you could provide:

  • From ad-hoc retrieval to question-and-answering
  • From TFIDF to Learning-to-Rank
  • From known-item search to personalisation
  • From mono-lingual to cross-lingual retrieval
  • From Alta-Vista to Google
  • From ELIZA to Watson
  • From LSI to Deep Learning
  • From keywords to Word2Vec
  • From SERPs to straight answers
  • From forming to cluster labeling
  • From Cranfield to living labs

Big Data Analytics: Big Data management and data integration

Chairs: Matthias Hagen and Roman Kern

Big Data started out as a buzz word being used to describe a lot of different aspects. In the mean time Big Data has established itself and has been recognised as a field of Computer Science. This i-KNOW special track tries to bring together researchers working on Big Data problems and applications that go beyond the mere buzz word. We invite papers that contribute to the knowledge in three different areas of Big Data research i) the algorithmic infrastructure, ii) the data management and integration and iii) the analytical part. We particularly encourage papers that will serve as a stepping stone for future research and hint the direction of this young and fast moving research field. We also invite papers that demonstrate the added benefit by combining multiple data sources, especially for real-time applications. Thus topics of this special track focused on Big Data are:

  • Analytics and Data Mining
  • Data Management and Data Integration

  • Data-Sets
  • Evaluation Methodologies
  • Real World Applications
  • (Near) Real-Time Methods

Recommender Systems: from algorithms to Big Data recommendation systems

Chairs: Alexander Felfernig, Elisabeth Lex

Recommender systems combine historical data on user preferences, (user) similarities and past behavior to suggest and predict items a user might be looking for. While they have been proven successful in e.g. e-commerce applications, they can also support organizations in better identifying competences, help engage users in a continuous and dynamic knowledge exchange, and customize dissemination of knowledge as much as possible.

The objective of this special track is to bring together researchers and practitioners involved in developing, testing, and fielding recommender systems, especially in the area of knowledge management. The special track focuses on all aspects of recommender systems and it will provide a forum for discussing current practice and recent research results

Topics include but are not limited to:

  • Personalization and recommendations in knowledge management
  • Recommender algorithms
  • Case studies of real-world implementations

  • Recommendations in TEL
  • Trust and reputation in recommender systems
  • User modelling for recommendations
  • User interfaces for recommender systems
  • Scalability of recommender systems

Web Science: emerging knowledge flows in the web

Chairs: Claudia Müller-Birn, Denis Helic

The scale and the rate of the Web’s growth as well as the Web’s impact on our society is unparalleled by any other technology. The Web’s rapid development resulted in a socio-technological system that is increasingly challenging to analyze, understand, or modify. Over the last years, a number of crowdsourcing systems emerged in which humans and machines collaborative to build for example structured and unstructured knowledge bases. Understanding the dynamics and evolution of knowledge flows within these systems, as they depend on inherent social and informational structures, is of particular interest, because it is the dynamics of human and algorithmic participation that determines their final success or failure. In order to analyze such socio-technological systems an interplay between aspects of computer science with social science and psychology is required. Various lines of research lead to a new interdisciplinary field, called Web Science which promises to answer existing scientific and engineering challenges in this context. .Although Web Science studies people, organizations, and policies that shape and are shaped by the Web, it is also concerned with the Web’s engineering aspects such as the analysis and design of the architecture, protocols, data and applications, or algorithms. Thus, Web Science adopts approaches from network science to study the Web as a network of people, and it also adopts methods from the statistics, machine learning and data mining to examine the digital traces of user interactions with the Web’s content.

This special track focuses on all aspects of Web Science. As Web Science is an interdisciplinary field combining research from disciplines such as mathematics, computer science, economics, social science, sociology, history, or psychology papers should preferably demonstrate interdisciplinary work contributing new models, algorithms, data analysis, frameworks and applications relevance to any aspect of the Web Science.

Topics include but are not limited to:

  • Theory and methodology of Web Science
  • Analysis of human behavior using digital traces
  • Network analysis of the Web and of Web-based data
  • Web Mining
  • Web architecture
  • Web Data
  • Web practices and communities
  • Knowledge and education on the Web
  • Humanities on the Web
  • Collective intelligence and collaborative production
  • Social Media analytics
  • Web economics, social entrepreneurship and innovation
  • Intellectual property and the commons
  • Case studies of crowdsourcing systems such as Wikipedia, Facebook, Twitter, World of Warcraft, open source software as well as empirical findings in related applications

Data-Driven Business: privacy and security perspective

Chairs: Herbert Leitold, Reinhard Posch

Data-driven business carries great potential and opportunities, but also risks: Invasion of privacy and security are concerns when utilising increasing amounts of data. With paradigms like cloud computing or big data this has an international dimension, spanning various legislations and a multitude of organisations providing or processing data. Such an environment asks for novel security paradigms, as well as a proper legal framework. The session aims to bring to together researchers to discuss security and privacy challenges in data-driven business. Both legal and technical contributions are sought to discuss on areas like:

  • Privacy-preserving technologies
  • Anonymity and pseudonymity
  • Auditing, assessment, and compliance
  • Authentication and Identification
  • Context-aware encryption or data masking
  • Legal barriers in a global, data-driven economy
  • Legislation-aware computing
  • Mobile and smart devices security
  • Searchable, attribute-based, identity based, or homomorphic encryption
  • Security and Trust Management
  • Security policy enforcement in multi-organisational environments
  • Trust-enhancing and trust-enabling technologies

The Future of (Knowledge) Management: in data-driven businesses

Chair: Klaus North

The ever increasing amount and variety of data and information can be a source of inspiration or confusion. As data are on the lowest level of the knowledge ladder they require to be associated with meaning to become information, which needs skillful interpretation in a specific context as a basis for decision making. This track invites contributors to explore and discuss critical challenges, developments and solutions for management in general and knowledge management in particular in data-driven businesses. We invite conceptional as well as empirical papers on issues such as:

  • Can data drive businesses or is it knowledge and competence that drives business?
  • What are the mental models behind “data-driven” businesses and how do they differ regarding “knowledge-driven” businesses?
  • Which knowledge is needed to interpret huge amounts of data?
  • Which role does domain knowledge play in the interpretation of data?
  • What are the implications for decision making based on data or based on intuition?
  • How will work and leadership of knowledge workers change?
  • How does innovation happen in data-driven businesses?
  • What will be the role of explicit data/information and tacit knowledge?
  • What will be the role of communities and networks?
  • How do organizations learn based on big data?
Submitted papers will go through a regular review procedure. All accepted papers of the main track and all special tracks will be published in ACM ICPS. In addition, selected papers of all special tracks will be invited for publishing extended versions in a Special Issue on “15 Years Knowledge Management” in the Journal of Universal Computer Science (
