While the performance of an information retrieval (IR) system can be enhanced through the compression of its posting lists, there is little recent work in the literature that thoroughly compares and analyses  ...  Moreover, we observe that the frequency and position posting information in Web corpora that have large volumes of anchor text are more challenging to compress, yet compression is beneficial in reducing  ...  Different orderings of the postings in the posting lists change both the algorithm for ranked retrieval and the underlying representation of postings in the inverted index, such as how they are compressed  ...
