Design and Implementation of English Multimedia Corpus

With the development of information technology and big data technology, the construction of corpora has become possible. This article designs a corpus based on English audiovisual and oral communication. The corpus model abstracts English audiovisual speaking into activity perspective, activity perspective, and system perspective. Firstly, in order to solve the problem of processing multimedia corpora based on English audiovisual conversations, a hierarchical processing model for multimedia corpora is proposed. This model provides a hierarchical interpretation of the processing process of multimedia corpus from three levels: physical layer, semantic layer, whole paragraph, and discourse processing layer. Secondly, based on the multimedia corpus model, relevant requirements were proposed, and a multimedia corpus system was further designed and implemented. Finally, a system functional test was conducted on the corpus, and the test results showed that in the five test cases, the traffic and query execution time between different sites increased with the increase of data volume. The test results indicate that the multimedia corpus system basically meets the relevant requirements.
