Our goal in participating in FIRE 2011 evaluation campaign is to analyse and evaluate the retrieval effectiveness of our implemented retrieval system when using Marathi language.

5 · log 7 · 1 is defined as follows while In the DFR-GL2 model Equation 5. 1 1 · 1 is defined as in 8 1 Finally we have also implemented one approach based on language model (LM) [9]. In this case, the underlying paradigm is based on a non-parametric probabilistic model. We have opted the model suggested by Hiemstra [10] using the JelinekMercer smoothing [11] scheme as shown in Equation 9. 30 for all index terms) lc is an estimation of the corpus C length. Stopword List Different words do not have the same importance in describing the semantic content of a document (or a query).

Our evaluation was carried out with title and description fields of test topics, and the Lemur search engine. We used plain unprocessed word index as the baseline, and n-gramming and stemming as competing methods. The evaluation results show 30%, 16% and 70% relative mean average precision improvements for Bengali, Gujarati and Marathi respectively when comparing the FCG method to plain words. The method shows competitive performance in comparison to n-gramming and stemming. 1 Introduction One of the basic problems of full-text retrieval is the variation of word forms that is caused by the morphology of natural languages.
