Extraction of phrasal knowledge, such as proper names, domain-specific keyphrases and lexical templates from a domain-specific text collection are significant for developing effective information retrieval systems for the Internet. In this paper, we are going to briefly introduce our ongoing research on automatic phrasal knowledge acquisition for EnglishChinese bilingual texts. In addition to the technique of keyphrase extraction which will be described in details, the underlying techniques consist of lexical template extraction, phrase translation extraction and high-order Markov language model construction are introduced in short.
