Cross-lingual information retrieval

We will define the task of Information retrieval (IR) and Cross-lingual (IR) and present its methods and approaches. Then we will present our current research state including: reranking hypotheses of machine-translated queries for better IR results, query expansion based on machine learning, comparison between query-translation and document translation and then the effect of morphological processing(stemming, lemmatization) of both documents and queries on IR results. Finally we present the dataset that we developed for this research.
