Comparing inverted files and signature files for searching a large lexicon

Ben Carterette, Fazli Can
2005 Information Processing & Management  
Signature files and inverted files are well-known index structures.  ...  Using n-grams to index lexicon terms, a bit-sliced signature file can be compressed to a smaller size than an inverted file if each n-gram sets only one bit in the term signature.  ...  We thank Justin Zobel for making his inverted file code freely available. We are very grateful to the referees, whose comments and suggestions greatly improved the focus of this work. Note.  ...

Vertical framing of superimposed signature files using partial evaluation of queries

Seyit Kocberbera, Fazli Can
1997 Information Processing & Management  
A new signature file method, Multi-Frame Signature File (MFSF), is introduced by extending the bit-sliced signature file method.  ...  In MFSF, a signature file is divided into variable sized vertical frames with different on-bit densities to optimize the response time using a partial query evaluation methodology.  ...  Acknowledgemenrs-We are grateful to a referee for insightful comments that improved the presentation  ...
