  • Using natural language processing for question answering in closed and open domains 

    Latifi, Majid (Universitat Politècnica de Catalunya, 2018-05-25)
    Tesi
    Accés obert
    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 ...
  • Real-time quality visualization of medical models on commodity and mobile devices

    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 ...
  • Low-rank regularization for high-dimensional sparse conjunctive feature spaces in information extraction 

    Primadhanty, Audi (Universitat Politècnica de Catalunya, 2017-11-17)
    Tesi
    Accés obert
    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 ...
  • Structure discovery techniques for circuit design and process model visualization 

    San Pedro Martín, Javier de (Universitat Politècnica de Catalunya, 2017-10-27)
    Tesi
    Accés obert
    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 

    Sánchez Charles, David (Universitat Politècnica de Catalunya, 2017-09-18)
    Tesi
    Accés obert
    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

    Tesi
    Accés obert
    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 

    Oriol Hilari, Xavier (Universitat Politècnica de Catalunya, 2017-07-11)
    Tesi
    Accés obert
    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
