A hybrid approach for item collection recommendations : an application to automatic playlist continuation
Current recommender systems aim mainly to generate accurate item recommendations, without properly evaluating the multiple dimensions of the recommendation problem. However, in many domains, like in music, where items are ...
Analysis of class C G-protein coupled receptors using supervised classification methods
G protein-coupled receptors (GPCRs) are cell membrane proteins with a key role in regulating the function of cells. This is the result of their ability to transmit extracellular signals, which makes them relevant for ...
Human-smart rollator interaction for gait analysis and fall prevention using learning methods and the i-Walker
The ability to walk is typically related to several bio-mechanical components that are involved in the gait cycle (or stride), including free mobility of joints, particularly in the legs; coordination of muscle activity ...
Realistic reconstruction and rendering of detailed 3D scenarios from multiple data sources
During the last years, we have witnessed significant improvements in digital terrain modeling, mainly through photogrammetric techniques based on satellite and aerial photography, as well as laser scanning. These techniques ...
A soft computing decision support framework for e-learning
Supported by technological development and its impact on everyday activities, e-Learning and b-Learning (Blended Learning) have experienced rapid growth mainly in higher education and training. Its inherent ability to break ...
Using natural language processing for question answering in closed and open domains
With regard to the growth in the amount of social, environmental, and biomedical information available digitally, there is a growing need for Question Answering (QA) systems that can empower users to master this new wealth ...
Real-time quality visualization of medical models on commodity and mobile devices
This thesis concerns the specific field of visualization of medical models using commodity and mobile devices. Mechanisms for medical imaging acquisition such as MRI, CT, and micro-CT scanners are continuously evolving, ...
Algebraic dependency grammar
We propose a mathematical formalism called Algebraic Dependency Grammar with applications to formal linguistics and to formal language theory. Regarding formal linguistics we aim to address the problem of grammaticality ...
Open source software ecosystems quality analysis from data sources
Background: Open source software (OSS) and software ecosystems (SECOs) are two consolidated research areas in software engineering. The adoption of OSS by firms, governments, researchers and practitioners has been increasing ...
Low-rank regularization for high-dimensional sparse conjunctive feature spaces in information extraction
One of the challenges in Natural Language Processing (NLP) is the unstructured nature of texts, in which useful information is not easily identifiable. Information Extraction (IE) aims to alleviate it by enabling automatic ...
Knowledge-based and data-driven approaches for geographical information access
Geographical Information Access (GeoIA) can be defined as a way of retrieving information from textual collections that includes the automatic analysis and interpretation of the geographical constraints and terms present ...
Structure discovery techniques for circuit design and process model visualization
Graphs are one of the most used abstractions in many knowledge fields because of the easy and flexibility by which graphs can represent relationships between objects. The pervasiveness of graphs in many disciplines means ...
Supporting decentralized collaborative processes in the digital transformation
Crowdsourcing, the art of involving several individuals in the decentralized execution of business activities, is being positioned as the replacement of outsourcing, as it allows organization to reach a capable workforce ...
Efficient approximate string matching techniques for sequence alignment
One of the outstanding milestones achieved in recent years in the field of biotechnology research has been the development of high-throughput sequencing (HTS). Due to the fact that at the moment it is technically impossible ...
A computational intelligence analysis of G proteincoupled receptor sequinces for pharmacoproteomic applications
Arguably, drug research has contributed more to the progress of medicine during the past decades than any other scientific factor. One of the main areas of drug research is related to the analysis of proteins. The world ...
Incremental checking and maintenance of UML/OCL integrity constraints
Ensuring the data correctness of some information system is a crucial task. So, software engineers specify sets of integrity constraints that should be satisfied by the system's data. These constraints, however, can be ...
Exploiting word embeddings for modeling bilexical relations
There has been an exponential surge of text data in the recent years. As a consequence, unsupervised methods that make use of this data have been steadily growing in the field of natural language processing (NLP). Word ...
Advanced inspection techniques for molecular simulations
Molecular dynamics simulations are computer simulations of the physical movements of atoms and molecules, and the interactions between them. In the particular cases we focus on (pharmaceutical drug design and enzymatic ...
Supporting the context life cycle in service-oriented computing
Current software community players like academy and industry have been changing the traditional paradigms of software engineering towards context-awareness and distributed computing. Nowadays, service-oriented computing ...
Algorithms and methodologies for interconnect reliability analysis of integrated circuits
The phenomenal progress of computing devices has been largely made possible by the sustained efforts of semiconductor industry in innovating techniques for extremely large-scale integration. Indeed, gigantically integrated ...
