Optimizarea regăsirii informaţiilor prin modelarea matematică
The Optimization of Retrieving Information Through Mathematical Modeling

Summary/Abstract: Information Retrieval Systems are software that save and carry out the management of the information contained in documents. Any Information Retrieval System is based on a mathematical model. The main mathematical models on which the Information Retrieval Systems are based on are: the Boolean model, the Vector Space model, the probabilistic model and the linguistic model. In addition to these classical models, in the recent years there have been added the models based on clustering methods, Latent Semantic Indexing and Support Vector Machines. The present article describes the principles underlying these models, the advantages and disadvantages for each model, with a view to clarify the role these models play or may play in the information retrieval process..
