Self-Indexed Grammar-Based Compression
Self-indexes aim at representing text collections in a compressed format that allows extracting arbitrary portions and also offers indexed searching on the collection. Current self-indexes are unable of fully exploiting the redundancy of highly repetitive text collections that arise in several applications. Grammar-based compression is well suited to exploit such repetitiveness. We introduce th...
متن کاملOnline Self-Indexed Grammar Compression
Although several grammar-based self-indexes have been proposed thus far, their applicability is limited to offline settings where whole input texts are prepared, thus requiring to rebuild index structures for given additional inputs, which is often the case in the big data era. In this paper, we present the first online self-indexed grammar compression named OESP-index that can gradually build ...
متن کاملGrammar-Based Graph Compression
We present a new graph compressor that works by recursively detecting repeated substructures and representing them through grammar rules. We show that for a large number of graphs the compressor obtains smaller representations than other approaches. Specific queries such as reachability between two nodes or regular path queries can be evaluated in linear time (or quadratic times, respectively),...
متن کاملGrammar - Based Compression By
P rograms that must run at or near top speed must use native machine code, but some programs have more modest performance requirements. For example, a cellular telephone handset might include software that reacts to key-strokes and spends most of its time waiting for the next input. An interpreted code can run quickly enough for such applications and can be smaller than machine code. Witness th...
