Kui Lam Kwok, L. Papadopoulos, Kathy Y. Y. Kwan · Text REtrieval Conference · 1992
Our strategy to information retrieval and to the TREC experiments is based on technique that have previously been demonstrated to work for small to medium size collections: 1) use of document components for retrieval and term weighting; 2) two-word phrases to achieve better precision and recale; 3) combination of retrieval methods; and 4) network implementation with learning capability to support feedback and query expansion
