Efficient Identification of Implicit Facts in Incomplete OWL2-EL Knowledge Bases
Integrating incomplete and possibly inconsistent data from various sources is a challenge that arises in several application areas, especially in the management of scientific data. A rising trend for data integration is to model the data as axioms in the Web Ontology Language (OWL) and use inference rules to identify new facts. Although there are several approaches that employ OWL for data inte...
متن کاملQuery Rewriting under Linear EL Knowledge Bases
With the adoption of the recent SPARQL 1.1 standard, RDF databases are capable of directly answering more expressive queries than simple conjunctive queries. We exploit such capabilities to answer conjunctive queries (CQs) under ontologies expressed in the description logic called linear EL , a restricted form of EL. In particular, we show a query answering algorithm that rewrites a given CQ in...
متن کاملPairwise Tensor Factorization for learning new facts in Knowledge Bases
Knowledge bases provide with the benefit of organizing knowledge in the relational form but suffer from incompleteness of new entities and relationships. Prior work on relation extraction has been focused on supervised learning techniques which are quite expensive. An alternative approach based on distant supervision has been of significant interest where one aligns database records with senten...
متن کاملEfficient Reasoning in Multiagent Knowledge Bases
In many applications, agents must reason about what other agents know, whether to coordinate with them or to come out on top in a competitive situation. However in general, reasoning in a multiagent epistemic logic such as Kn has high complexity. In this paper, we look at a restricted class of knowledge bases that are sets of modal literals. We call these proper epistemic knowledge bases (PEKBs...
متن کاملBrain, a Library for the OWL2 EL profile
Brain is a Java library facilitating the interaction with OWL2 EL ontologies. The library aims at bridging the gap between graphical user interfaces such as Protege and the OWL-API: It provides a series of convenience methods to create and query knowledge bases using the Manchester syntax. The library is useful to develop web applications and particularly suited for the biomedical domain. Brain...
