Abstract: This article offers a approach to the automatic discovery
of semantic concepts and links in the domain of Oil Exploration
and Production (E&P). Machine learning methods combined with
textual pre-processing techniques were used to detect local patterns in
texts and, thus, generate new concepts and new semantic links. Even
using more specific vocabularies within the oil domain, our approach
has achieved satisfactory results, suggesting that the proposal can
be applied in other domains and languages, requiring only minor
adjustments.
Abstract: This proposal aims for semantic enrichment between
glossaries using the Simple Knowledge Organization System (SKOS)
vocabulary to discover synonyms, hyponyms and hyperonyms
semiautomatically, in Brazilian Portuguese, generating new semantic
relationships based on WordNet. To evaluate the quality of this
proposed model, experiments were performed by the use of two sets
containing new relations, being one generated automatically and the
other manually mapped by the domain expert. The applied evaluation
metrics were precision, recall, f-score, and confidence interval. The
results obtained demonstrate that the applied method in the field of
Oil Production and Extraction (E&P) is effective, which suggests that
it can be used to improve the quality of terminological mappings.
The procedure, although adding complexity in its elaboration, can be
reproduced in others domains.
