Natural languages are full of collocations, recurrent combinations of words that co-occur more often than expected by chance and that correspond to arbitrary word usages. Recent work in lexicography indicates that collocations are pervasive in English; apparently, they are common in all types of writing, including both technical and nontechnical genres.(More)
Collocations are notoriously difficult for non-native speakers to translate, primarily because they are opaque and cannot be translated on a word-byword basis. We describe a program named Champollion which, given a pair of parallel corpora in two different languages and a list of collocations in one of them, automatically produces their translations. Our(More)
Collocational knowledge is necessary for language generation. The problem is that collocations come in a large variety of forms. They can involve two, three or more words, these words can be of different syntactic categories and they can be involved in more or less rigid ways. This leads to two main difficulties: collocational knowledge has to be acquired(More)
In previous papers we presented methods for retrieving collocations from large samples of texts. We described a tool, Xtract, that implements these methods and able to retrieve a wide range of collocations in a two stage process. These methods a.s well as other related methods however have some limitations. Mainly, the produced collocations do not include(More)
In contrast to other kinds of libraries, software libraries need to be conceptually organized. When looking for a component, the main concern of users is the functionality of the desired component; implementation details are secondary. Software reuse would be enhanced with conceptually organized large libraries of software components. In this paper, we(More)
Colony stimulating factor-1 (CSF-1) and the CSF-1 receptor (the c-fms proto-oncogene product) are expressed during the proliferation of the L6 alpha 1 rat myogenic cell line and both are down-regulated during the differentiation to myotubes. Biologically active CSF-1 was shown to be secreted into the culture medium by L6 alpha 1 myoblasts and while they(More)
