Using Arabic Wordnet for semantic indexation in information retrieval system
This work addresses the challenge of enhancing Arabic information retrieval systems for users, but it is incremental as it applies an existing method to a specific domain.
The paper tackled the problem of improving Arabic information retrieval by using Arabic WordNet for semantic indexing, resulting in a global improvement in system performance.
In the context of arabic Information Retrieval Systems (IRS) guided by arabic ontology and to enable those systems to better respond to user requirements, this paper aims to representing documents and queries by the best concepts extracted from Arabic Wordnet. Identified concepts belonging to Arabic WordNet synsets are extracted from documents and queries, and those having a single sense are expanded. The expanded query is then used by the IRS to retrieve the relevant documents searched. Our experiments are based primarily on a medium size corpus of arabic text. The results obtained shown us that there are a global improvement in the performance of the arabic IRS.
