【摘要】：網(wǎng)絡(luò)的發(fā)展極大地影響了我們的生活方式,它讓我們在更容易獲取信息的同時(shí),也徹頭徹尾地將我們陷入無邊無際的信息海洋之中。每時(shí)每刻我們都要自覺或不自覺,被動(dòng)或主動(dòng)地面對數(shù)十億頁面的網(wǎng)絡(luò)信息,想找回自己所需要的信息簡直是“大海撈針”。搜索引擎的出現(xiàn),讓我們有了探索信息海洋的指南針。搜索引擎被業(yè)界公認(rèn)為繼廣告、網(wǎng)絡(luò)游戲、無線增值之后互聯(lián)網(wǎng)的第四桶金。萬維網(wǎng)(World Wide Web)是Internet上增長領(lǐng)域最快、最靈活、最通用的一個(gè)多種信息集成的多媒體信息發(fā)布、瀏覽與檢索系統(tǒng)。Web的巨大魅力是為以多媒體方式發(fā)布信息提供了一條快車道。因此,有人用這樣的公式解釋“Web=Internet+多媒體”。隨著信息技術(shù)的不斷發(fā)展和推廣應(yīng)用,基于內(nèi)容的多媒體信息索引與檢索已經(jīng)成為多媒體研究中的熱點(diǎn)課題之一。多媒體信息主要包括文本、圖像、圖形、聲音、視頻、動(dòng)畫等形式, Flash動(dòng)畫作為互聯(lián)網(wǎng)催生的新興視覺媒介,從誕生至今十年的時(shí)間,已經(jīng)發(fā)展成為網(wǎng)絡(luò)上最流行的多媒體表現(xiàn)形式。 本文以發(fā)布格式為SWF的Flash動(dòng)畫為研究對象,以SWF動(dòng)畫文件結(jié)構(gòu)和Flash制作過程為依據(jù),對Flash動(dòng)畫進(jìn)行了內(nèi)容特征分析和內(nèi)容特征標(biāo)引,按照一定的數(shù)據(jù)結(jié)構(gòu)創(chuàng)建了基于Flash動(dòng)畫內(nèi)容分析的索引數(shù)據(jù)庫,并采用動(dòng)態(tài)網(wǎng)頁技術(shù)和數(shù)據(jù)庫技術(shù)建立了一個(gè)基于內(nèi)容的Flash檢索系統(tǒng)。 基于內(nèi)容的Flash檢索系統(tǒng)是一個(gè)專業(yè)的垂直搜索引擎系統(tǒng),以快速索引和檢索網(wǎng)頁Flash動(dòng)畫為最終目的。首先,我們通過網(wǎng)絡(luò)蜘蛛程序按照指定的URL從互聯(lián)網(wǎng)上采集包含F(xiàn)lash文件的網(wǎng)頁鏈接,然后從這些網(wǎng)頁文件上提取Flash文件路徑,并下載Flash文件;然后,對下載到的Flash文件進(jìn)行內(nèi)容分析,進(jìn)而通過分析程序?qū)lash文件進(jìn)行結(jié)構(gòu)化標(biāo)注,在此基礎(chǔ)上,建立基于Flash內(nèi)容分析的索引數(shù)據(jù)庫,并運(yùn)用動(dòng)態(tài)網(wǎng)頁技術(shù)設(shè)計(jì)適當(dāng)?shù)牟樵兘涌诤陀押玫牟樵兘缑?按照一定的算法模型對數(shù)據(jù)庫進(jìn)行條件檢索,最終,將包含動(dòng)畫摘要和動(dòng)畫鏈接等信息的頁面返回給用戶。 本文首先討論了目前國內(nèi)外基于內(nèi)容的Flash檢索領(lǐng)域的研究現(xiàn)狀和發(fā)展趨勢;然后對基于內(nèi)容的Flash檢索的關(guān)鍵技術(shù)和方法進(jìn)行了研究,并著重研究了一種基于改進(jìn)的布爾檢索算法;接著論述了基于內(nèi)容的Flash檢索系統(tǒng)的實(shí)現(xiàn)方法,并對Flash檢索的界面設(shè)計(jì)和數(shù)據(jù)結(jié)構(gòu)進(jìn)行了研究,建立了一個(gè)基于內(nèi)容的Flash檢索原型系統(tǒng);最后,我們討論了關(guān)于海量數(shù)據(jù)庫的編碼和壓縮問題,對系統(tǒng)數(shù)據(jù)庫進(jìn)行了一定的改進(jìn)和優(yōu)化,并對檢索結(jié)果進(jìn)行了分析和統(tǒng)計(jì),實(shí)驗(yàn)結(jié)果表明,該系統(tǒng)檢索Flash準(zhǔn)確率較高,相對于傳統(tǒng)搜索引擎來說,該系統(tǒng)對采用的算法對提高Flash的查全率與查準(zhǔn)率具有積極意義。 Flash資源以其形象、生動(dòng)、直觀的優(yōu)點(diǎn),在建構(gòu)主義學(xué)習(xí)環(huán)境中起著非常重要的作用,將合適的Flash資源應(yīng)用到教育領(lǐng)域,對于建構(gòu)主義學(xué)習(xí)環(huán)境的創(chuàng)建,提高教育教學(xué)效果具有重要意義,基于內(nèi)容的Flash檢索系統(tǒng)在一定程度上能夠更準(zhǔn)確有效地幫助學(xué)生查找到自己所需要的Flash動(dòng)畫資源。
[Abstract]:The development of the network has greatly affected our way of life, and it makes it easier for us to get information, and we're going to be in an endless, information-free ocean. All the time, we have to consciously or unconsciously, passive or active ground to billions of pages of network information, to find the information that you need is simply a "fishing needle in large sea". The presence of a search engine gives us a compass to explore the information oceans. The search engine is recognized by the industry as the fourth barrel of the internet following advertising, online gaming, and wireless value-added. World Wide Web is one of the fastest, most flexible, and most versatile information-integrated multimedia information publishing, browsing and retrieval systems in the Internet. The great charm of the Web is to provide a fast lane for publishing information in a multimedia way. Therefore, it is possible to interpret the "Web = Internet + Multimedia" in such a formula. With the development and application of information technology, multimedia information indexing and retrieval based on content has become one of the hot topics in multimedia research. The multimedia information mainly includes the form of text, image, graphics, sound, video, animation and so on. Flash animation is the emerging visual medium generated by the Internet, and has developed into the most popular multimedia presentation in the network from the time of its birth to the present ten years. In this paper, the Flash animation of SWF is used as the research object, and the content feature analysis and content feature indexing are carried out on the Flash animation based on the SWF animation file structure and the Flash production process. The index number based on the content analysis of Flash animation is created according to a certain data structure. The dynamic web technology and database technology are used to build a content-based Flash retrieval system. System. Content-based Flash retrieval system is a professional vertical search engine system to quickly index and retrieve web page Flash animation for the end purpose, firstly, the network spider program acquires the webpage link containing the Flash file from the internet according to the specified URL, then extracts the Flash file path from the webpage files, and downloads the Flash file; and then, the downloaded Flash file The content content analysis is carried out, and then the Flash file is structured and marked by the analysis program, on the basis of which, the index database based on the Flash content analysis is established, the appropriate query interface and the friendly query interface are designed by using the dynamic web page technology, and the database is fed into the database according to a certain algorithm model. Line condition retrieval, and finally, a page containing information such as an animation summary and an animation link In this paper, the present research status and development trend of the content-based Flash retrieval field at home and abroad are discussed in this paper. The key technologies and methods of the content-based Flash retrieval are also studied. In this paper, the implementation of Flash retrieval system based on content is discussed, the interface design and data structure of Flash retrieval are studied, a prototype system of Flash retrieval based on content is established, and finally, we discuss the mass database. The coding and compression problems of the system are improved and optimized, and the results of the retrieval are analyzed and statistics. The experimental results show that the system has higher accuracy of retrieval and compared with that of the system. In the case of the traditional search engine, the system of the system is used to improve the full rate and the check of Flash. Flash resources play a very important role in the learning environment of constructivism, and apply the appropriate Flash resources to the field of education. The teaching effect is of great significance, and the content-based Flash retrieval system can help the students find their own needs more accurately and effectively
