We present an approach for semantic rela- tion extraction between nominals that com- bines shallow and deep syntactic processing and semantic information using kernel meth- ods. Two information sources are …...

This paper proposes a new approach to dynamically determine the tree span for tree kernel-based semantic relation ex- traction. It exploits constituent dependen- cies to keep the nodes and their …...

AbstractIn this work we propose a hybrid unsupervised approach for semantic relation extraction from Italian and English texts. The system takes as input pairs of ""distributionally similar"" terms, possibly involved …...

We present an approach for semantic re- lation extraction between nominals that combines semantic information with shal- low syntactic processing. We propose to use the ResearchCyc knowledge base as a …...

AbstractWe present a gold standard for semantic relation extraction in the food domain for German. The relation types that we address are motivated by scenarios for which IT applications present …...

Recursive neural models, which use syn- tactic parse trees to recursively generate representations bottom-up, are a popular architecture. However there have not been rigorous evaluations showing for exactly which tasks …...

AbstractThis paper describes the first task on semantic relation extraction and classification in scientific paper abstracts at SemEval 2018. The challenge focuses on domain-specific semantic relations and includes three different …...

AbstractMany automatic semantic relation extraction tools extract subject-predicate-object triples from unstructured text. However, a large quantity of these triples merely represent background knowledge. We explore using full texts of biomedical …...

AbstractThis paper is devoted to the extraction of entities and semantic relations between them from scientific texts, where we consider scientific terms as entities. In this paper, we present a …...
