Retrieving Domain‐Specific Collocations by Co‐occurrences and Word Order Constraints

Abstract

In this paper, we describe a method for automatically retrieving collocations from large text corpora. This method comprises the following stages: (1) extracting strings of characters as units of collocations, and (2) extracting recurrent combinations of strings as collocations. Through this method, various types of domain-specific collocations can be retrieved simultaneously. This method is practical because it uses plain text with no specific-languagedependent information, such as lexical knowledge and parts of speech. Experimental results using English and Japanese text corpora show that the method is equally applicable to both languages.

Extracting Terminologically Relevant Collocations in the Translation of Chinese Monograph

“…This methodology is language dependent rather than language independent, and the system requires highly specialized linguistic techniques to identify the possible candidate terms. Second, purely statistical systems extract discriminating multiword terms from the text corpora by means of association measures [5,6,7]. As they use plain text corpora and only require the information appearing in texts, such systems are highly flexible and extract relevant units independently from the domain and the language of the input text.…”
