摘要： The invention concerns a detection of duplicate tuples in a database. Previous domain independent detection of duplicated tuples relied on standard similarity functions (e.g., edit distance, cosine metric) between multi-attribute tuples. However, such prior art approaches result in large numbers of false positives if they are used to identify domain-specific abbreviations and conventions. In accordance with the invention a process for duplicate detection is implemented based on interpreting records from multiple dimensional tables in a data warehouse, which are associated with hierarchies specified through key—foreign key relationships in a snowflake schema. The invention exploits the extra knowledge available from the table hierarchy to develop a high quality, scalable duplicate detection process.

摘要： A server may receive an article that is retrieved from a server; determine whether the article satisfies first criteria based on content of the first article; annotate the article with a first article type when the article satisfies the first criteria; determine whether the article satisfies second criteria based on information associated with the article; annotate the article with a second article type when the article satisfies the second criteria; and store the article in association with a topic and at least one of the first article type or the second article type. The different server may be associated with a news website.
摘要翻译：服务器可以接收从服务器检索的文章; 根据第一篇文章的内容确定文章是否满足第一标准; 当文章满足第一个标准时，用第一个文章类型注释文章; 根据与文章相关的信息确定文章是否满足第二标准; 当文章满足第二个标准时，用第二个文章类型注释文章; 并且存储与主题相关联的文章以及第一文章类型或第二文章类型中的至少一个。不同的服务器可能与新闻网站相关联。
