A semantic approach for the requirement-driven discovery of web resources in the Life Sciences

Abstract: Abstract. Research in the Life Sciences depends on the integration of large, distributed and heterogeneous web resources (e.g. data sources and web services). The discovery of which of these resources are the most appropriate to solve a given task is a complex research question, since there are many candidate resources and there is little, mostly unstructured, metadata to be able to decide among them.In this paper we contribute with a semi-automatic approach, based on semantic techniques, to assist researchers… Show more

“…To be able to exploit this contextual information, our approach is based on a topic-based ranking model described in [35]. Using this topic-based model, we can estimate the conditional probabilities of each concept c under a pre-defined set of topics t k (1≤ k ≤ n ) (where n is the number of topics) which roughly corresponds to bioinformatics generic tasks [36], such as sequence analysis, protein identification, etc.…”

“…Compared to other annotation alternatives, this tool offers a clean and simple approach and shows a good trade-off between performance and scalability. The tool has been successfully used in other scenarios, such us in [37], where they annotate the textual descriptions provided by catalogues of Life Science Web Services and align them with the user requirements. It is worth mentioning that this tool does not disambiguate annotations and can make errors.…”

“…Nevertheless, metadata should characterize and describe objects in a relevant manner, which is sometimes (websites in particular) not the case (Ardo 2010). In case of web resources, the data are also very often unstructured and heterogeneous (Perez-Catalan et al 2013). …”
