I am using both dtSearch and LogiTerm. I agree with most of Terry's comments on the tool. I want to add that I use the LogiTrans function of LogiTerm. Once you a have collection of bitexts, you can run LogiTrans on the text you need to translate. LogiTrans will find concordant translations in the bitexts and replace the source text with the translation in the case of 100% matches. Matches lower than 100% are highlighted and can be edited with LogiTerm's macros in MS Word. For the type of translation I do (documentary translation), LogiTerm/LogiTrans saves me a lot of time and aggravation. If a client sends me a ton of reference documents in the target and source languages, the raw materials for bitexts, I don't have to index and search them. LogiTrans finds the matches and inserts them in the source text.
