LDAC2024 - Linked Data
in Architecture
and Construction
Call for Participation
LDAC presents a forum for technical and applied research on the usage of semantic web, linked data and web of data technologies for architecture and construction (design, engineering, construction, operation).
The workshop aims at gathering researchers, industry stakeholders, and standardization bodies of the broader Linked Building Data (LBD) community. The workshop series has been held yearly since 2012, taking place in numerous locations and venues, sometimes co-located with AEC or web technology conferences and sometimes as independent events. The workshop welcomes industry participation and brings together experts from the AEC field with computer scientists and software developers familiar with (semantic) web technologies.
Three Tracks
In 2024, the workshop will again be organised as a fully stand-alone event, in combination with a summer school and in one single location in Bochum, Germany. As in the past years, the workshop covers work from three perspectives: research, technical discussions and industry developments. In short, LDAC welcomes stakeholders from research and practice and serves as a common communication platform to advance and innovate the use of linked data in architecture and construction.
Semantics Scope
LDAC aims at providing a forum for technical discussion on the topic of handling data in architecture and construction. A large part of the workshop is concerned with the use of (semantic) web technologies. Research is welcomed on the use of ontologies and vocabularies for representing building data, 3D geometry, product data, geospatial data, infrastructure data, HVAC data, sensor data, and so forth.
Call for Papers (PDF)Focus on Data
Additionally, the workshop welcomes work on how to combine these highly semantic datasets with other data sets, which in the case of architecture and construction consist mainly of geometry and sensor data streams. Using different data storage techniques (semantic data stores, time series databases, key-value stores), the purpose of the LDAC workshop is to investigate ways in which data can be combined into a complete and holistic set of available building data.
Industry Practice
Practical techniques of combining datasets in the current web-based and data-driven world are explored: Internet of Things, Machine Learning, Digital Twins, Building Information Modelling. A number of industry cases are invited, presenting interesting ideas, use cases, solutions or experience reports related to practical applications at any stage of construction lifecycle.

Keynote Title
Lessons Learnt from Researching on Semantic Interoperability
Seamless interoperability is still a challenge in the current landscape of information systems, which need to be aware of cross-sectorial information coming not only from other information systems but also from people or diverse entities in the world. This talk presents some lessons learnt from researching and implementing semantic interoperability. On the one hand, it will cover the semantic aspect of interoperability, giving guidelines on the development of ontologies and on their role for sharing consensus. On the other hand, it will deal with the interoperability perspective, giving hints on engineering semantically interoperable systems and presenting challenges in decentralised interoperability, such as the privacy one.

Keynote Title
Overcoming boundaries: How Linked Data and Machine Learning are Transforming Enterprise Software
In a world driven by data, the ability to effectively structure, process and utilize information is more crucial than ever. However, traditional enterprise software and its technological paradigms often reach their limits. In this keynote, we outline how the elevait suite pushes the boundaries of traditional data processing by applying linked data principles and machine learning. Our platform is domain and use case agnostic, but is widely used in the construction industry to automate business processes and increase efficiency. Learn how we use advanced workflows to semantically annotate data, train ML models and generate data according to linked data principles and use it in process automation. We also show how no-code tools are used to define business rules and how automatically generated user interfaces make it easier to interact with this data. Using concrete examples from our platform, we will demonstrate how these technologies are implemented in real-life scenarios to create precise, scalable and efficient solutions. We will also share valuable lessons learned that can help you drive your development and research projects forward.
Program
The LDAC program includes a Workshop with Poster Track and Industry Track, as well as a Summer School.
The LDAC 2024 workshop is organised as a two-day plenary event. This includes keynote presentations, plenary research paper sessions, a poster session, and an industry track.
Summer School
This year, there will again be an LDAC Summer School, directly preceding the workshop, and in the same location. The LDAC Summer School will take place 10-12 June, in Bochum, Germany. This Summer School focuses entirely on the use of linked data and semantic web technologies for the built environment. In this summer school, experts and researchers in the use of these technologies for the AEC industry will share their knowledge and expertise to a limited audience of 40 participants. The summer school targets starting PhD students and starting industry professionals within the AEC industry. Coding experience is highly recommended.
Important: The Summer School participants will present the results of their work on Thursday afternoon, right after the lunch break, and before the poster and industry track!
