英文摘要 | Computer-based systems can produce enormous retrieval sets even when good search logic is used. Sometimes this is desirable, but more often it is not. Appropriate filters can limit search results, but they represent only a partial solution. Simple ranking techniques are needed that are both effective and easily understood by the humans doing the searching. Optimal search output, whether from a traditional database or the Internet, will result when intuitive interfaces are designed that inspire confidence while making the necessary mathematics transparent. Weighted-term searching using powers of two, a technique proposed early in the history of information retrieval, can be simplified and used in combination with modern graphics and textual input to achieve thest results. |
