Automatic annotation of bioinformatics workflows with biomedical ontologies
Legacy scientific workflows, and the services within them, often present
scarce and unstructured (i.e. textual) descriptions. This makes it difficult to
find, share and reuse them, thus dramatically reducing their value to the
community. This paper presents an approach to annotating workflows and their
subcomponents with ontology terms, in an attempt to describe these artifacts in
a structured way. Despite a dearth of even textual descriptions, we
automatically annotated 530 myExperiment bioinformatics-related workflows,
including more than 2600 workflow-associated services, with relevant
ontological terms. Quantitative evaluation of the Information Content of these
terms suggests that, in cases where annotation was possible at all, the
annotation quality was comparable to manually curated bioinformatics resources.Comment: 6th International Symposium on Leveraging Applications (ISoLA 2014

Km4City Ontology Building vs Data Harvesting and Cleaning for Smart-city Services
Presently, a very large number of public and private data sets are available
from local governments. In most cases, they are not semantically interoperable
and a huge human effort would be needed to create integrated ontologies and
knowledge base for smart city. Smart City ontology is not yet standardized, and
a lot of research work is needed to identify models that can easily support the
data reconciliation, the management of the complexity, to allow the data
reasoning. In this paper, a system for data ingestion and reconciliation of
smart cities related aspects as road graph, services available on the roads,
traffic sensors etc., is proposed. The system allows managing a big data volume
of data coming from a variety of sources considering both static and dynamic
data. These data are mapped to a smart-city ontology, called KM4City (Knowledge
Model for City), and stored into an RDF-Store where they are available for
applications via SPARQL queries to provide new services to the users via
specific applications of public administration and enterprises. The paper
presents the process adopted to produce the ontology and the big data
architecture for the knowledge base feeding on the basis of open and private
data, and the mechanisms adopted for the data verification, reconciliation and
validation. Some examples about the possible usage of the coherent big data
knowledge base produced are also offered and are accessible from the RDF-Store
and related services. The article also presented the work performed about
reconciliation algorithms and their comparative assessment and selection
Relation Ontology II
Conceived as follow-up to recent efforts destined to supply .owl ontologies with relational tools of greater complexity, the present article focuses on four main paths, all of them consisting in providing biomedical ontologies with formal means to express (1) deviations from normality, (2) topological connectedness, (3) inherence and (4) causality and function
On Pain and the Privation Theory of Evil
The paper argues that pain is not a good counter-example to the privation theory of evil. Objectors to the privation thesis see pain as too real to be accounted for in privative terms. However, the properties for which pain is intuitively thought of as real, i.e. its localised nature, intensity, and quality are features of the senso-somatic aspect of pain. This is a problem for the objectors because, as findings of modern science clearly demonstrate, the senso-somatic aspect of pain is neurologically and clinically separate from the emotional-psychological aspect of suffering. The intuition that what seems so real in pain is also the source of pain’s negative value thus falls apart. As far as the affective aspect of pain, i.e. ”painfulness’ is concerned, it cannot refute the privation thesis either. For even if this is indeed the source of pain’s badness, the affective aspect is best accounted for in privative terms of loss and negation. The same holds for the effect of pain on the aching person
Creating Intelligent Computational Edge through Semantic Mediation
This research proposes semantic mediation based on reasoning and the first order logic for mediating the best possible configuration of Computational Edge, relevant for software applications which may benefit for running computations with proximity to their data sources. The mediation considers the context in which these applications exist and exploits the semantic of that context for decision making on where computational elements should reside and which data they should use. The application of semantic mediation could address the initiative to accommodate algorithms from predictive and learning technologies, push AI towards computational edges and potentially contribute towards creating a computing continuum
Extension of Ontologies Assisted by Automated Reasoning Systems
A method to extend ontologies with the assistance of automated
reasoning systems and preserving a kind of completeness with
respect to their associate conceptualizations is presented. The use of such
systems makes feasible the ontological insertion of new concepts, but it
is necessary to re-interpret the older ones with respect to new ontological
commitments.We illustrate the method extending a well-known ontology
about spatial relationships, the called Region Connection Calculus.Ministerio de Educación y Ciencia TIN2004-0388
Intellectual Property, Globalization, and Left-Libertarianism
Intellectual property has become the apple of discord in today’s moral and political debates. Although it has been approached from many different perspectives, a final conclusion has not been reached. In this paper I will offer a new way of thinking about intellectual property rights (IPRs), from a left-libertarian perspective. My thesis is that IPRs are not (natural) original rights, aprioric rights, as it is usually argued. They are derived rights hence any claim for intellectual property is weaker than the correlative duties attached to self-ownership and world-ownership rights, which are of crucial importance in any left-libertarian view. Moreover, IPRs lack priority in front of these two original rights and should be overridden by stronger claims of justice. Thus, as derived rights, IPRs should not benefit of strong enforcement like any original rights especially if it could be in the latters’ detriment
