- Abstract
- Reviews similarity measures for searching names. These measures deal with phonetic similarity, typing errors, and plain string similarity. Shows experimentally that all 3 approaches lead to significantly higher retrieval quality than plain identity. Further improvements are possible by combining different methods. Develops a probabilistic interpretation of string similarity that leads to better results than an ad-hoc approach
