Extraction of Hyponymic Relations in French with Knowledge-Pattern-Based Word Sketches (2020.lrec-1)
Copied to clipboard
| Challenge: | Hyponymy is the cornerstone of taxonomies and concept hierarchies. |
| Approach: | They propose a French hyponymic sketch grammar for Sketch Engine based on knowledge patterns. |
| Outcome: | The proposed grammar extracts hyponymic pairs from any user-owned corpus. |
Towards the Inference of Semantic Relations in Complex Nominals: a Pilot Study (L18-1)
Copied to clipboard
| Challenge: | Complex nominals (CNs) show similar external forms but encode different semantic relations because of noun packing. |
| Approach: | They propose to use paraphrases to convey conceptual content of english two-term CNs in the domain of environmental science to disambiguate the semantic relation between constituents of CN. |
| Outcome: | The proposed method disambiguates the semantic relation between constituents of the CN and infers the semantic relations in these multi-word terms. |
Representing Multiword Term Variation in a Terminological Knowledge Base: a Corpus-Based Study (2020.lrec-1)
Copied to clipboard
| Challenge: | Multiword terms are the most frequent type of lexical units in scientific and technical communication. rendering them in another language is not easy due to their cognitive complexity, proliferation of different forms, and their unsystematic representation in terminographic resources. |
| Approach: | They evaluated Spanish translation variants of multiword terms in three parallel corpora, two comparable corporales and two terminological resources. |
| Outcome: | The results show that multiword terms exhibit a significant degree of term variation . the proposed model is based on a set of criteria for determining which variants should be selected . |
Ideological Knowledge Representation: Framing Climate Change in EcoLexicon (2024.lrec-main)
Copied to clipboard
| Challenge: | a method to extract ideological knowledge from corpora is proposed to represent environmental concepts and terms in terminological resources . political discourse is not considered specialized language, but politicians use scientific terms to soften the message . |
| Approach: | They propose to use terminological knowledge bases to represent political discourse on environmental concepts and terms. |
| Outcome: | The proposed method shows how climate change discourse changes across ideological spectrum . it uses spanish and english parliamentary debates to extract ideological knowledge from corpora. |
Manzanilla: An Image Annotation Tool for TKB Building (L18-1)
Copied to clipboard
| Challenge: | Currently, images are stored in the TKB as a whole and are only linked to the concept itself. |
| Approach: | They propose to use images as representations of concepts in EcoLexicon to improve image reusability and consistency. |
| Outcome: | The tool was created to enhance the consistency of knowledge representation through images with the conceptual knowledge in EcoLexicon and to improve image reusability. |
Humanitarian Corpora for English, French and Spanish (2024.lrec-main)
Copied to clipboard
| Challenge: | et al., a leading database of humanitarian documents, compiled with ReliefWeb reports . documents selected with language identification and noise reduction techniques . authors present corpora of English, French and Spanish humanitarian documents . |
| Approach: | They present three corpora of English, French and Spanish humanitarian documents compiled with ReliefWeb reports . documents were tokenized, lemmatized, tagged by part of speech, and enriched with metadata . authors propose a project to develop a humanitarian dictionary with a focus on conceptual variation . |
| Outcome: | The corpora were compiled to satisfy the research needs of the Humanitarian Encyclopedia project with a focus on conceptual variation. |
Evaluating EcoLexiCAT: a Terminology-Enhanced CAT Tool (L18-1)
Copied to clipboard
| Challenge: | EcoLexiCAT is a web-based tool for terminology-enhanced translation of environmental texts . most terminological modules in CAT tools do not go beyond a simple glossary of source and target terms . |
| Approach: | They propose to integrate terminology-enhanced translation into a web-based tool . EcoLexiCAT is a terminology-enriched CAT tool for the English-Spanish-English translation . |
| Outcome: | The EcoLexiCAT tool is an open-source version of the CAT tool MateCat . it enriches a source text with information from a multimodal and multilingual terminological knowledge base on the environment . |
