MG4J at TREC 2005.
Paolo Boldi, Sebastiano Vigna · Text REtrieval Conference · 2005
MG4J participated in two tracks of TREC 2005 — the ad hoc task and the efficiency task of the Terabyte Track (find all the relevant documents with high precision from 25.2 million pages from the .gov domain). It was the first time the MG4J group participated to TREC, and we concentrated our efforts on the ad hoc task, using a combination of techniques based on a new multi-index minimal-interval semantics and PageRank.
