Towards Efficient Positional Inverted Index †
We address the problem of positional indexing in the natural language domain. The positional inverted index contains the information of the word positions. Thus, it is able to recover the original text file, which implies that it is not necessary to store the original file. Our Positional Inverted Self-Index (PISI) stores the word position gaps encoded by variable byte code. Inverted lists of s...
متن کاملEfficient Compressed Inverted Index Skipping for Disjunctive Text-Queries
In this paper we look at a combination of bulk-compression, partial query processing and skipping for document-ordered inverted indexes. We propose a new inverted index organization, and provide an updated version of the MaxScore method by Turtle and Flood and a skipping-adapted version of the space-limited adaptive pruning method by Lester et al. Both our methods significantly reduce the numbe...
متن کاملEfficient online index maintenance for contiguous inverted lists q
Search engines and other text retrieval systems use high-performance inverted indexes to provide efficient text query evaluation. Algorithms for fast query evaluation and index construction are well-known, but relatively little has been published concerning update. In this paper, we experimentally evaluate the two main alternative strategies for index maintenance in the presence of insertions, ...

متن کاملAn efficient inverted index technique for XML documents using RDBMS
The inverted index is widely used in the existing information retrieval field. In order to support containment queries for structured documents such as XML, it needs to be extended. Previous work suggested an extension in storing the inverted index for XML documents and processing containment queries, and compared two implementation options: using an RDBMS and using an Information Retrieval (IR...
