As of January, 2007, the Japanese language editors of the Reading Tutor Web Dictionary (http://marmot.chuta.jp/) have completed the entries for 8,000 words which include 25,000 example sentences. Words used in the example sentences have been limited to words up through level 2 of the Japanese Language Proficiency Test. To make more effective use of the data in the dictionary for both learning and for materials development, a search system has been created for example sentences. This system enables the user to not only look for the meaning of the word and its example sentences, but to also search for other sentences in the dictionary which contain the word in question. Furthermore, the system links the user to a translated version of the example sentences and the head words of words in the sentence. It is hoped that users can make use of the system to deepen their understanding of compound words and collocations.
