Translation memories
• Approaches
• Sentence-based approach
• Character-string-in-bitext-based approach
• Advantages
• Disadvantages
Marija Brkić, Sanja Seljan, Božena Bašić Mikulić
5/22
Sentence-based approach
• Translation Units (Tus)
– Sentences
– Titles
– Subtitles
– List entries
• High precision, low recall search
• Fuzzy matching
• Noise
• Silence
Marija Brkić, Sanja Seljan, Božena Bašić Mikulić
6/22
Character-string-in-bitextbased approach
• Character strings of any length
– Several consecutive identical sentences
• Unreliably small matches
• Noise
• No support for fuzzy matching
• Silence
• Recycling internal repetitions through
terminology databases

7/22
Advantages
• Consistency
– Internal and external repetitions
– Shared projects
• Speed
– Globalization
• Cost reduction
• Preservation of original page layout
• Statistics
– Scheduling localization projects

Disadvantages
• Initial decrease in productivity
• Beneficiary effects felt only on repetitive
texts
• TM needs to be of considerable size
• Is alignment worthwhile and preconditions
met?
• Database maintenance
