Dr. David Lewis

Associate Professor (Computer Science)


I am the Director of the Knowledge and Data Engineering Group (KDEG). I have been key the growth and development of this research group, which now totals 9 academics and over 50 postdocs and PhD students. I collaborate closely with other group academics in securing a growing portfolio of funding for the group and I have personally secured €5.4 Million in competitive research funding. I am a PI in CNGL Centre for Global Intelligent Content which is funded from the SFI Centres for Science Engineering and Technology (CSET) programme. CNGL is centred in KDEG and has received SFI funding for TCD and its collaborating institutions of over €50 Million over the last 7 years. I am also a PI in the ADAPT Centre, which is the successor to CNGL, and has just been awarded a further €23 Million funding from the SFI accompanied by €7.5 Million cash funding from industry. I have been active in developing KDEG's internal organisation to efficiently manage the steadily growing cohort of PhD students, post-doctoral researchers and research assistants, including the provision of seminar series, workshops, training, mentoring and commercialisation supports. I have led research teams in 9 EU and 7 Irish funded collaborative projects which involve: close collaboration with other TCD academics and international academic and industrial partners; formation and coordination of research plans; negotiation of and controlling expenditure within agreed budgets; and dealing effectively with sponsors. My research interest is in Management Knowledge, and how it can be captured, modelled, analysed and exchanged in decentralised decision-making settings. I have been responsible for several undergraduate (4ICT12, 3ICT1 and CS3BC2) and postgraduate (CS7009) taught modules and supervision of 6 undergraduate and 23 MSc dissertation projects. I have supervised 5 PhD students to completion, co-supervised 6 more and have 4 PhD student in progress currently.

My research interest is in Management Knowledge, and how it can be captured, modelled, analysed and exchanged in decentralised decision-making settings. I am therefore interested in developing data and knowledge engineering techniques for management knowledge that is used to achieve shared goals in situations where decision-making authority is not centralised, but diffused across multiple individuals or organisations. For such collaborative decision-making, I investigate the use of declarative knowledge techniques, including open data formats, ontological knowledge formats such as description logic and declarative operational instructions such as policy rules, service specifications and workflow models. The effectiveness of employing these techniques is measured through: i) The ease with which software engineers can integrate knowledge sharing models with native data models existing in legacy and proprietary management systems. ii) The additional computational and data retrieval loads imposed by employing declarative, knowledge-based representations of management information, compared to existing solutions with implicit representations. iii) The reduction in cognitive load for human decision makers against their need to compensate for the shortfalls exhibited by automated decision support that from components leveraging explicit management knowledge, e.g. in accuracy of machine-learning and natural language processing (NLP) components and the limits in domain knowledge completeness in reasoning components. iv) The degree to which decision-makers can assimilate knowledge in making accurate and timely management decisions and the impact of personalised and interactive data visualsiation techniques. Application of these techniques and their evaluation has had impact in the following application areas: a) Telecommunications Management: I was an early proponent of the extensible mark-up language for management information exchange and services, highlighting the performance and engineering tradeoffs. This approach is now common place in the telecoms industry, where long value chains are common. I also championed the topic of open semantic knowledge formats and issues of federated management in the research community. b) Smart Building Management: Here we have used open semantic models and 3D interactive data representations to enable building occupants and building managers to reconcile the management of several heterogeneous heating, ventilation and air conditioning systems; location tracking and environmental sensors and electronic access control systems to achieve physical security, comfort and energy efficiency. c) Online Communities: These exhibit a high degree decentralisation in managing the conduct of the community and the creation and sharing of digital resources, here we developed and evaluated a novel set of design considerations for developing community data visualisation tools to assist community decision-making. d) Intelligent Content Processing: This field addresses the application of NLP and personalisation technology to the processing of digital content, primarily in applications aimed at engaging with customers, citizens and leaners online. This is the core topic of CNGL and the new ADAPT Centre. Here I have pioneered the use of open semantic models to monitor the interplay between human language workers (e.g. translators & terminologists) and NLP components, and curating the result to improve those components. I have therefore demonstrated a substantial and sustained research output in decentralised management knowledge applied to a number of domains.
