We provide a comprehensive survey of the research literature that applies Information Extraction techniques in Semantic Web setting.Works intersection these two areas can be seen from overlapping perspectives: using resources (languages/ontologies/knowledge-bases/tools) to improve Extraction, and/or populate Web.In more detail, we focus on extraction and linking three elements: entities, concepts relations.Extraction involves identifying (textual) mentions referring such elements given...

Reliably processing and interlinking medical information has been recognized as a critical foundation to the digital transformation of workflows, despite development ontologies, optimization these major bottleneck medicine. The advent large language models brought great excitement, maybe solution medicines' 'communication problem' is in sight, but how can known weaknesses models, such hallucination non-determinism, be tempered? Retrieval Augmented Generation, particularly through knowledge...

The tables embedded in Wikipedia articles contain rich, semi-structured encyclopaedic content. However, the cumulative content of these cannot be queried against. We thus propose methods to recover semantics and, particular, extract facts from them form RDF triples. Our core method uses an existing Linked Data knowledge-base find pre-existing relations between entities tables, suggesting same as holding for other analogous columns on different rows. that such approach extracts triples...

In this article the authors discuss challenges of performing reasoning on large scale RDF datasets from Web. Using ter-Horst’s pD* fragment OWL as a base, compose rule-based framework for application to web data: they argue their decisions using observations undesirable examples taken directly The further temper through consideration “authoritative sources” which counter-acts an observed behaviour term “ontology hijacking”: new ontologies published Web re-defining semantics existing entities...
