Vector-space techniques can be used for extracting semantically similar words from the co-occurrence statistics of words in large text data. We have used a technique called Random Indexing to accumulate context vectors for Swedish, French and Italian. We have then used the context vectors to perform automatic query expansion. In this paper, we report on our CLEF 2002 experiments on Swedish, French and Italian monolingual query expansion.
