RANKING OF RECORDS IN A RELATIONAL DATABASE |
| 摘要 |
<p>A method for generating a probabilistic relational database based on a previous relational database, wherein the probability estimation is carried out within the relational paradigm. The method may include frequency-based and information theoretic based (idf-based) estimation of tuple probabilities. The method generalises the use of information retrieval ranking methods such that these and new ranking methods are available for relational databases.</p> |
