Towards a Welsh Semantic Annotation System (L18-1)
Copied to clipboard
| Challenge: | Automatic semantic annotation of natural language data is an important task in Natural Language Processing. |
| Approach: | They develop a Welsh semantic annotation tool that can be used to analyze Welsh text . it uses Lancaster's USAS semantic classification scheme to tag words with semantic tags . |
| Outcome: | The proposed tool can cover up to 91.78% of words in Welsh text. |
Profiling Medical Journal Articles Using a Gene Ontology Semantic Tagger (L18-1)

| Challenge: | a growing number of scientific publications are based on sub-divisions and sub-communities of expertise becoming disconnected from each other. |
| Approach: | They propose to examine corpora derived from bodies of genetics literature and use it to make comparisons and improve retrieval methods. |
| Outcome: | The proposed methods will help to make comparisons and improve retrieval methods using domain knowledge via an existing gene ontology. |

| Challenge: | a novel infrastructure for biomedical text mining combines NLP and corpus linguistics methods to provide a comprehensive corpus for literature-based discovery. |
| Approach: | They propose a novel pipeline for the collection, annotation, storage, retrieval and analysis of biomedical and life sciences literature . it uses an updatable Gene Ontology Semantic Tagger and a NLP pipeline scheduler to collect and process the corpus. |
| Outcome: | The proposed infrastructure allows for extreme-scale research on the open access PubMed Central archive. |
Metaphorical Expressions in Automatic Arabic Sentiment Analysis (2020.lrec-1)
Copied to clipboard
| Challenge: | Existing algorithms and tools for sentiment analysis are lacking in dealing with Arabic metaphorical expressions. |
| Approach: | They propose to use Arabic metaphors in automatic Arabic sentiment analysis to examine the performance of a state-of-art Arabic sentiment tool on metaphors. |
| Outcome: | The proposed model outperforms the state-of-the-art sentiment analysis tool on metaphors and gain a deeper insight into the issue. |
Survey on Thai NLP Language Resources and Tools (2022.lrec-1)
Copied to clipboard
| Challenge: | Thai language is one of the under-resourced languages in the NLP domain, although it is spoken by approximately 70 million people globally. |
| Approach: | They propose to use Thai language as an example to understand how NLP works and how it can be applied to Thai language. |
| Outcome: | The results show that Thai NLP research has progressed over the past three decades, especially on upstream tasks such as tokenisation, but research on downstream tasks such syntactic parsing and semantic analysis is still limited. |
