Artificial intelligence (AI) is front and center in the data-driven revolution that has been taking place in the last couple of years with the increasing availability of large amounts of data (“big data”) in virtually every domain. The now dominant paradigm of data-driven AI, powered by sophisticated machine learning algorithms, employs big data to build intelligent applications and support fact-based decision making. The focus of data-driven AI is on learning (domain) models and keeping those models up-to-date by using statistical methods over big data, in contrast to the manual modeling approach prevalent in traditional, knowledge-based AI.
While data-driven AI has led to significant breakthroughs, it also comes with a number of disadvantages. First, models generated by machine learning algorithms often cannot be inspected and understood by a human being, thus lacking explainability. Furthermore, integration of preexisting domain knowledge into learned models – prior to or after learning – is difficult. Finally, correct application of data-driven AI depends on the domain, problem, and organizational context while considering human aspects as well. Conceptual modeling can be the key to applying data-driven AI in a meaningful, correct, and time-efficient way while improving maintainability, usability, and explainability.
While we welcome all kinds of contributions that bring together approaches from conceptual modeling and data-driven AI, we wish to put an emphasis on the following key areas:
1. Augmenting Data-Driven AI with Conceptual Modeling for Explainable AI
Data-driven AI generates models that may be either symbolic (e.g. rules, decision trees) or sub-symbolic (neural networks). These models will then be used in application systems to implement specific functions and/or behavior, e.g., object detection in images, scene understanding in videos, medical diagnoses, interpreting sensor data. Typically, these models cannot be inspected and understood by a human being. Models of a symbolic nature tend to be too complex, whereas sub-symbolic models do not contain structural elements that can be understood by humans. In many application scenarios, however, this is an important requirement. Various approaches to explainability, model testing and verification are based on integrating data-driven AI with approaches from conceptual modeling.
2. Supporting Data-Driven Decision Making with Conceptual Modeling
Business intelligence (BI) and analytics projects require domain experts, business people, data scientists, and engineers to communicate with each other in a common language. Stakeholders must collaborate in various ways in order to gain a common understanding of the problem as well as to decide on the appropriate data model, architecture, algorithms, user interfaces, etc. Yet, BI and analytics projects often involve low-level, ad hoc data wrangling and programming, which increases development effort and reduces usability of BI and analytics solutions. Furthermore, data analytics and machine learning techniques are often misapplied, adversely affecting the validity of analysis results in practice. A conceptual perspective on data-driven decision making ensures that analysts employ algorithms in the correct context and use the appropriate systems to process the available data in a meaningful way. Conceptual modeling allows to move data-driven decision making onto a higher level of abstraction, facilitating implementation and use of data analytics solutions while allowing stakeholders with different skills to communicate with each other.
3. Using Data-Driven Model Generation for Conceptual Modeling
Conceptual modeling is not necessarily a (purely) manual undertaking but can benefit from approaches to model generation. For example, a first draft of a conceptual model might be generated from existing data which will then be extended and refined manually. Furthermore, individual parts of a conceptual model may be generated automatically whereas other parts are handcrafted. Existing models might be (semi-)automatically improved based on regularities derived from newly available data, which may form the basis for self-tuning and self-repairing systems.
