"text": "A concordance tool is particularly useful for studying a piece of literature when thinking in terms of a particular word, phrase or theme. It will show how often and where a word occurs, so can be helpful in building up some idea of how different themes recur within an article or a collection of articles. Concordances have been indispensable for lexicographers and increasingly considered instrumental for promoting learning effectiveness and motivation for language instructors and learners. A bilingual concordance tool is like a monolingual concordance, except that each sentence is associated with translation counterpart in a second language. It could be extremely useful for bilingual lexicographers, human translators and second language learners. Pierre Isabelle, in 1993, pointed out: \"existing translations contain more solutions to more translation problems than any other existing resource.\" It is particularly useful and convenient when the resource of existing translations is made available on the Internet. Web based bilingual concordances have proved to be very useful and popular.",

In addition to the similar functionalities provided by TransSearch, TotalRecall comes with an additional feature making the solution more easily recognized: the user not only gets all the citations related to the expression in question, but also gets to see the translation counterpart highlighted.",

While the length-based approach (Church and Gale 1991) to sentence alignment produces surprisingly good results for the close language pair of French and English at success rates well over 96%, it does not fair as well for distant language pairs such as English and Chinese. Work on sentence alignment of English and Chinese texts (Wu 1994) , indicates that the lengths of English and Chinese texts are not as highly correlated as in French-English task, leading to lower success rate (85-94%) for length-based aligners. Simard, Foster, and Isabelle (1992) pointed out cognates in two close languages such as English and French can be used to measure the likelihood of mutual translation. However, for the English-Chinese pair, there are no orthographic, phonetic or semantic cognates readily recognizable by the computer. Therefore, the cognate-based approach is not applicable to the Chinese-English tasks.",

We are now using a newer alignment method based on punctuation statistics. Although the average ratio of the punctuation counts in a text is low (less than 15%), punctuations provide valid additional evidence, helping to achieve high degree of alignment precision. It turns out that punctuations alone are telling evidences for sentence alignment, if we do more than hard matching of punctuations and take into consideration of intrinsic sequencing of punctuation in ordered comparison. Experiment results show that the punctuation-based approach outperforms the length-based approach with precision rates approaching 98%.",
