Main Research Interests

I'm particularly interested in research themes related to natural language and spatial / spatio-temporal information.

The work builds on a variety of research areas in computer science, including:

  • Artificial Intelligence (e.g., Knowledge Representation, Automated Reasoning, Machine Learning, Natural Language Processing);

  • Advanced Databases;

  • Conceptual Modelling;

The main thread of my research encompasses the following fields:

  • Natural Language Processing applied to different domains.

    • Text mining;

    • Text classification;

    • Dialog Representation.

  • Geospatial Research:

    • Linguistic aspects of space and space-time;

    • Spatial / Spatio-temporal Knowledge Representation & Reasoning;

    • Handling Spatial Vagueness and Uncertainty;

    • Geospatial Ontologies;

    • Commonsense representations of space; cognitive and philosophical aspects of space;

The work is applied to different (broader) fields of research, such as:

  • Volunteered Geographic Information - VGI;

  • Geographic Information Retrieval - GIR (toponym resolution, spatio-temporal indexing, relevance ranking, query formulation and visualisation);

  • Geographic Information Systems - GIS (spatial and spatio-temporal data modelling, user-aware/context-aware systems, user interaction and visualisation, satellite image processing);

  • Modelling Geospatial Semantics (including event/process modelling for dynamic GIS, reasoning over multi-granularities);

  • Intelligent Transportation Systems - ITS;

  • Smart Cities;

  • Robotics, Industrial Automation, Computer Vision (e.g., event detection in video);

Other Research Interests

Many of the fields investigated have characteristics that are independent from space and time. Thus I'm also generally interested in:

  • Everything that involves formal representations of knowledge;

  • Ontology development, semantic integration & interoperability, and semantic technologies in general;

  • Semantic Web in General;

  • Social Network Analysis, Social Media Mining, Text Mining;

  • Information Retrieval in General;

  • Natural Language Processing;

  • Data Modelling and Management;

  • Databases (Multimedia DBs, Distributed DBs, Datawarehouse, Data Mining);

  • Digital Image Processing (with focus on Satellite Image Classification);
