Abstract

The invention relates to an unstructured data management method for the field of film and television materials. The method is used for carrying out distributed storage and query and visual managementon unstructured data in the field of film and television materials. The distributed storage specifically comprises the steps of: establishing knowledge ontology of the field of film and television materials, wherein the knowledge ontology comprises a domain knowledge base KS and a tag classification library LS; and determining a storage path of the unstructured data, storing the data in an HDFS (Hadoop Distributed File System) according to the storage path and storing description information of the unstructured data of the film and television materials in a database. The query and visual management specifically comprises the steps of: expanding the search condition of a user by calculating the semantic similarity and correlation degree; searching according to the expanded search conditionby utilizing an ElasticSearch search engine in combination with a Jena inference algorithm, obtaining a search result and feeding back to the user; and displaying the searched data by utilizing a visual tool. Compared with the prior art, the method disclosed by the invention has the advantages that the method is suitable for the unstructured data management; the search condition can be expanded; the query is flexible; the visual displaying is realized and the like.

Description

technical field [0001] The invention relates to the field of unstructured data management, in particular to an unstructured data management method used in the field of film and television materials. Background technique [0002] Video materials are widely used in film and television post-production, teaching, research and many other fields. Data that can be represented by a unified structure is called structured data; data with variable field lengths and no predefined data model is called unstructured data. Traditional relational databases can manage structured data well, but in the context of massive heterogeneous data expansion, relational databases have exposed obvious limitations. [0003] Text, images, audio, video, etc. in film and television materials are all unstructured data. Compared with structured data, it has problems such as storage management, query processing and query optimization. Therefore, how to effectively store and query unstructured video data amon...
