网络影视基于本体的高效检索系统研究
网络影视基于本体的高效检索系统研究(开题报告,外文翻译,论文28000字,代码)
摘 要
网络影视包括：电影、电视剧、新闻、纪录片等，它们在接入Internet时，几乎都会同时放上内容简介。目前的影视检索只能靠影视名、主角名、上映年份等一些简单的关键字进行检索，但用户有时对目标影视的这些字段很难精确记忆，这就导致了检索结果的误检和漏检。本课题将基于本体的检索技术运用于网络影视检索系统中，并能够挖掘潜在的检索知识。本体的引入，克服了传统影视检索基于关键字检索带来的问题，并且本体的属性也提供了推理出隐含知识的基础，可检索出与检索条件具有相同语义信息的影视，提高了查全率和查准率。
本课题验证了本体的高效检索理论的可行性，对各功能模块的可实施性进行了详细的分析、设计。建立在理论研究基础之上，课题将借助于已有的开发工具，模拟实现一个简易的网络影视检索系统，该系统留有基于本体的语义检索接口。最终目的是为了实现基于本体的高效检索插件，该插件能嵌入到各大型影视检索网站上，弥补其语义检索的空缺。

Abstract [资料来源：www.doc163.com]
Online video including: movies, television dramas, news, documentaries, Internet access when they are, almost always at the same time put the contents Introduction. Video search can only rely on the current film and television were the main character name, release year and some simple keyword search, but users are sometimes the target film is difficult to accurately remember these fields, which led to the search results of false detection and leakage examination. The subject of ontology-based search technology used in online video retrieval system, and be able to tap the potential of search knowledge. The introduction of ontologies, to overcome the traditional keyword-based search video search to bring the problem and the properties of ontology reasoning also provides the basis for the implicit knowledge can be retrieved with the search conditions of the film with the same semantic information to improve the recall and precision rate.
The subject of ontology proved the feasibility of efficient retrieval theory of the functional modules can be implemented for a detailed analysis and design. Built on the basis of theoretical study, subjects will be developed by means of existing tools, simulation to achieve a simple online video search system, which leaves the semantics of ontology-based search interface. The ultimate goal is to achieve efficient retrieval based on ontology plug-in can be embedded into all major video search sites, to make up its semantic search vacancies. [资料来源：http://www.doc163.com]
