Text categorization and clustering methods. We build algorithms and tools for the identification of stylistically homogeneous categories.
Writing style representation. We study the effectiveness of several features that capture stylistic properties of documents including low-level features like character n-grams and more elaborated features using the output of natural language processing tools.
Intelligent information retrieval. We are interested in measuring document similarity based on stylistic criteria and identifying parts of a single document with distinct writing styles.
Text and web-page genre detection
Bayesian networks: We emphasize on reasoning under conditions of uncertainty in complex, changing environments.
Text Mining: We endeavor to use ontologies with standard linear algebra and pattern recognition techniques to reveal significant text patterns.
Inforainment Data Mining: We focus on creating intelligent, interactive games and other entertaining environments by analysing user behavior during gameplay activity,.
Privacy-Preserving data mining: We focus on keeping sensitive information hidden from mining tasks without deteriorating the mining performance.
High-scale, parallel data mining: We emphasize on dealing with high-dimensionality problems in an effective and efficient manner.

Image Processing and Computer Vision
Interactive Systems. We build tools appropriate to improve the image processing performance by using human feedback.
Historical Document Processing. We use intelligent systems in combination with classical document processing techniques intending to face common problems of historical in order to extract useful information from them.
We investigate the field of word spotting by the use of image matching techniques in order to face the failure of OCR and perform information retrieval in difficult cases of Document Images, e.g Historical Documents.
We investigate the field of Image Binarization. We have proposed appropriate techniques for Document Images. We have built appropriate databases and we suggested objective ways for the evaluation of binarization algorithms.

IoT / Pervasive Computing
End User Development. We build conceptual models and tools that empower end-users to create IoT applications.
Pervasive Computing Frameworks. We study software engineering approaches and develop components and services that enable the dynamic adaptation of applications in pervasive computing environments.
Ambient Assisted Living. We study the use of serious games, machine learning techniques and ontologies to build platforms for enhancing the well-being and cognitive functions of older adults in ambient assisted living environments.
Smart education. We study IoT and other technologies like mobile and ubiquitous computing for enhancing learning practices on the basis of establishing communities of practice in the context of educational scenarios that incorporate such technologies.
