    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

    Abstract
    The original WAIS implementation by Thinking Machines and others treats documents as uniform bags of terms. Since most documents exhibit some internal structure, it is desirable to provide the user means to exploit this structure in his queries. Presents extensions to the freeWAIS indexer and server, which allows access to document structures using the original WAIS protocol. Major extensions include: arbitrary document formats, search in individual structure elements, stemming and phonetic search, support of 8-bit character sets, numeric concepts and operators. combination of Boolean and linear retrieval. Presents a WWW-WAIS gateway specially tailored for usage with freeWAIS-sf which transforms filled out HTML forms to the new query syntax
