Abstract
this paper, we only considered the pairs formed by two nouns or one adjective followed by a noun. A detailed description of the method can be found in [Evans & Zhai 96]. To test the effect of lexical atoms for any particular configuration of the system, we add the lexical atoms to the CLARIT lexicon, and specify that they should be treated as a non-separable indexing unit. The database and the queries are then processed using the extended lexicon to prevent lexical atoms from being decomposed. The results can be compared with a baseline obtained by using the standard CLARIT lexicon
