The Multimedia and Information Systems group at the Knowledge Media Institute of the Open University participated in the Expert Search and Document Search tasks of the Enterprise Track in TREC 2007. In both the document and expert search tasks, we have studied the effect of anchor texts in addition to document contents, document authority, url length, query expansion, and relevance feedback in ...

People provide information on their thoughts, perceptions, and activities through a wide range of channels, including social media. The acceptance media results in vast volume valuable data, variety format as well veracity. Analysis such ‘big data’ allows organizations analysts to make better faster decisions. However, this data had be quantified has extracted, which can very challenging becaus...

AI language models are a key component of natural processing (NLP), field artificial intelligence (AI) focused on enabling computers to understand and generate human language. Language other NLP approaches involve developing algorithms that can process, analyse text or speech trained vast amounts data using techniques ranging from rule-based statistical deep learning. The application is diverse...

Networking and collaboration in clinical care are increasingly entailing new requirements on supporting medical processes. The information technology (IT) in public health accordingly earns strategic relevance and encounters new potentials as well as challenging demands. The application of conceptual models in health care domain is almost entirely restricted to documentation tasks. Approaches l...

Currently, modelling of systems in the process industry requires the use of different specification languages for the specification of the discrete-event and continuous-time subsystems. In this way, models are restricted to individual subsystems of either a continuous-time or discrete-event nature. It is our aim to integrate such models, by using one language for the specification of complete p...
