kNowledge Intensive Computing for Healthcare Enterprises (NICHE)

The NICHE (kNowledge Intensive Computing for Healthcare Enterprises) Research Group conducts research in advancing knowledge technologies and developing innovative knowledge-intensive solutions, in particular for healthcare enterprises.

The NICHE group both promotes and pursues inter-disciplinary research whereby the group's investigations span from the abstract epistemological orientations of knowledge to the capture and representation of knowledge to practical operationalization of knowledge via intelligent systems.

Research Areas and
Projects:

The wide spectrum of activities conducted in NICHE group falls in the realm of four inter-related research areas:
1. Knowledge Management and Semantic Web
2. Health Informatics
3. Intelligent Information and Services Personalization
4. Health Data Mining

NICHE researchers work across a cross-section of the above-mentioned themes, developing both novel knowledge-centric methods and applying these methods in knowledge-intensive tools. Currently, the researchers are working towards the development of a knowledge creation, morphing and sharing framework for capturing and operationalizing heterogeneous knowledge modalities present within an enterprise; the development and application of intelligent techniques to customize web-based services and information content as per a user-model; the formal computerization of healthcare knowledge artifacts to offer point-of-care decision support services; and the application of knowledge and data-driven intelligent systems to provide innovative healthcare services for both practitioners and patients. Details of individual projects can be found at the individual researcher's websites. Our research projects are largely funded by government agencies, private organizations and industry.

Funding: The NICHE projects have been funded by CANARIE, National Sciences and Engineering Research Council of Canada (NSERC), Canadian Foundation of Innovation (CFI), Nova Scotia Health Research Foundation (NSHRF), Green Shield Foundation Canada and Agfa Healthcare Canada.

MALNIS

Combining textual content and link information for describing, classifying, clustering and visualizing networked information spaces formed by large collections of documents are the focal tasks of the MALNIS lab.  The core methodology involves the application of machine learning, graph theory and natural language processing to problems in networked information spaces, i.e. large document collections which have the form of a graph, where nodes are occupied by documents and links represent relations between documents (hyperlinks or citations). Specific research problems addressed include similarity and clustering based on both content and link information, low-dimensional representations of special text corpora based on knowledge resources such as Wikipedia and word, term and document embeddings, document summarization, and interactive visualization of document corpora to support high-recall interactive information retrieval and sense-making tasks for the subject matter expert. Networked information spaces of particular interest include the scientific and medical research literature, list servers of communities of experts, social media data streams, and grey literature. To address the computational requirements of these tasks, we have been using cloud computing resources provided by Compute Canada.

The MALNIS lab has active collaborations with the following universities:

  • University of São Paulo (Universidade de São Paulo), Sao Carlos, Brazil (Professors , , )

  • Universidade Federal de São Paulo (UNIFESP) (Prof. )

  • National University of the South (Universidad Nacional del Sur) & CONICET, Bahia Blanca, Argentina (Drs and )

  • Universidad Técnica Federico Santa María, Santiago, Chile ()

Students interested in doing a thesis with the MALNIS lab are encouraged to take as many of the following courses as possible as part of their course requirement towards their degree:

  • CSCI 4152/6509: Natural Language Processing
  • CSCI 6515: Machine Learning for Big Data
