摘要: Forms are a standard way of gathering data into database. Many applications need to support multiple users with evolving requirements. It is desirable automatically link dynamic forms the back-end We have developed FormMapper system, fully automatic solution that accepts user-created entry forms, and maps integrates them an existing database in same domain. The comprises two components: tree extraction form integration. component leverages probabilistic process, Hidden Markov Model (HMM), for extracting semantic structure form. In integration component, we develop merging procedure extends desired properties. conducted experiments evaluating performance system on several large databases designed from number complex forms. Our experimental results show promising: generated highly similar (87% overlapped) those by human experts, given set
