    Towards a Shared, Conceptual Model-Based Understanding of Proteins and Their Interactions

    [EN] Understanding the human genome is a big research challenge. The huge complexity and amount of genome data require extremely effective and efficient data management policies. A first crucial point is to obtain a shared understanding of the domain, which becomes a very hard task considering the number of different genome data sources. To make things more complicated, those data sources deal with different parts of genome-based information: we not only need to understand them well, but also to integrate and intercommunicate all the relevant information. The protein perspective is a good example: rich, well-known repositories such as UniProt provide a lot of valuable information that it is not easy to interpret and manage when we want to generate useful results. Proteomes and basic information, protein-protein interaction, protein structure, protein processing events, protein function, etc. provide a lot of information is that needs to be conceptually characterized and delimited. To facilitate the essential common understanding of the domain, this paper uses the case of proteins to analyze the data provided by Uniprot in order to make a sound conceptualization work for identifying the relevant domain concepts. A conceptual model of proteins is the result of this conceptualization process, explained in detail in this work. This holistic conceptual model of proteins presented in this paper is the result of achieving a precise ontological commitment. It establishes concepts and their relationships that are significant in order to have a solid basis to efficiently manage relevant genome data related to proteins.This work was supported in part by the Spanish State Research Agency under Grant TIN2016-80811-P, and in part by the Generalidad Valenciana under Grant PROMETEO/2018/176, co-financed with ERDF.León-Palacio, A.; Pastor López, O.

    Conceptual Modeling of Proteins Based on UniProt

    Clinical disease states reflect the interaction of a myriad of genetic and environ-mental contributions. In this context, a major challenge is to develop information systems and algorithms that can describe this complexity to facilitate an under-standing of the disease mechanisms as well as to guide the development and ap-plication of therapies. This work focuses on describing how a shared understand-ing of the domain can be achieved by analyzing the conceptual precision of the main concepts that should constitute the ontological commitment that is strictly required when studying an important area of research: the role that proteins play in the different functions carried out within the cell of any living systems. The contribution of this paper is to show the conceptual complexity of the UniProtKB database, and to let users face and manage that complexity by providing a sound and well-grounded conceptual background to achieve the shared understanding of the domain, a crucial aspect to allow the design of any fruitful data analytics-based strategy. A conceptual model for proteins is carefully developed taking the UniProtKB database as data source, explaining in detail the problems that have been faced together with their corresponding solutions.León Palacio, A.; Pastor López, O.

    Enhancing Precision Medicine: A Big Data-Driven Approach for the Management of Genomic Data

    Full text link
    [EN] The management of the exponential growth of data that Next Generation Sequencing techniques produce has become a challenge for researchers that are forced to delve into an ocean of complex data in order to extract new insights to unravel the secrets of human diseases. Initially, this can be faced as a Big Data-related problem, but the genomic data have particular and relevant challenges that make them different from other Big Data working domains. Genomic data are much more heterogeneous; they are spread in hundreds of repositories, represented in multiple formats, and have different levels of quality. In addition, getting meaningful conclusions from genomic data requires considering all of the relevant surrounding knowledge that is under continuous evolution. In this scenario, the precise identification of what makes Genome Data Management so different is essential in order to provide effective Big Data-based solutions. Genomic projects require dealing with the technological problems associated with data management, nomenclature standards, and quality issues that only robust Information Systems that use Big Data techniques can provide. The main contribution of this paper is to present a Big Data-driven approach for managing genomic data, that is adapted to the particularities of the domain and to show its applicability to improve genetic diagnoses, which is the core of the development of accurate Precision Medicine.This work was supported by the Spanish State Research Agency (grant number TIN2016-80811-P) and the Generalitat Valenciana (grant number PROMETEO/2018/176), and co-financed with ERDF.León-Palacio, A.; Pastor López, O.

    [EN] The objective of this thematic issue is to bring attention to actual research on Business Informatics, as being publicized on the 19th IEEE Conference on Business Informatics (CBI 2017), July 24-27, 2017, in Thessaloniki, Greece. The conference created a productive forum for researchers and practitioners from the fields that contribute to the construction, use and maintenance of information systems and the organisational context in which they are embedded. 10 papers were selected by the Program Chairs Prof. Peri Loucopoulos, Prof. Oscar Pastor and Prof. Jelena Zdravkovic to submit extended versions for a possible publication in Issue 13 of CSIMQ, as well as few external candidate submissions were considered.Zdravkovic, J.; Pastor López, O.; Loucopoulos, P.

    [EN] This study presents MoWebA, a navigational role-centric model driven development (MDD) proposal for web applications development. The approach was conceived considering a previous study of web methods and analysing some open issues. This article presents the fundamentals of the proposal; the methodological aspects for modelling and transformation processes; and the defined notations/techniques for modelling and transformation tasks, including their abstract and concrete syntax definitions. We include a summary of the validation experiences and main results, and a comparison against other related proposals, in order to highlight the main contributions of MoWebA.This research is partially supported by the CONACYT (Paraguay), through the INV-056 Project.González Toñánez, M.; Cernuzzi, L.; Pastor López, O.

    System: A core conceptual modeling construct for capturing complexity

    Get PDF
    [EN] The digitalization of human society continues at a relentless rate. However, to develop modern information technologies, the increasing complexity of the real-world must be modeled, suggest-ing the general need to reconsider how to carry out conceptual modeling. This research proposes that the often-overlooked notion of "system"should be a separate, and core, conceptual modeling construct and argues for incorporating it and related concepts, such as emergence, into existing approaches to conceptual modeling. The work conducts a synthesis of the ontology of systems and general systems theory. These modeling foundations are then used to propose a CESM+ template for conducing systems-grounded conceptual modeling. Several new conceptual modeling notations are introduced. The systemist modeling is then applied to a case study on the development of a citizen science platform. The case demonstrates the potential contributions of the systemist approach and identifies specific implications of explicit modeling with systems for theory and practice. The paper provides recommendations for how to incorporate systems into existing projects and suggests fruitful opportunities for future conceptual modeling research.We wish to thank the editor-in-chief, Carson Woo, and three anonymous reviewers for their exceptionally insightful and developmental comments.
