Multilanguage Library Search Systems

[摘要] This thesis presents an application of information retrieval in a multilingual environment, by computerising the documents stored in a library. These documents are either in English/French or in Arabic. Some approaches to processing them are discussed; the possibilities to mix the documents are studied and a solution is developed. English and French documents are grouped together and a method for their retrieval is developed. Arabic documents are not considered in their original scripts but are romanised. The proposed method for searching the Arabic documents is based on the reduction of the words into root-pattern pairs which is handled by a morphological study of the Arabic words. The Arabic documents are totally separated from English/French documents. Finally, a user interface and the implementation of the system are developed to realise the aim of this project. The user interface gives possibilities for the user of the library to search documents in either English/French or Arabic. File structures are presented in the context of information retrieval and an evaluation of the system in terms of efficiency is studied.
