【摘要】：CNNIC第33次中國(guó)互聯(lián)網(wǎng)絡(luò)發(fā)展?fàn)顩r統(tǒng)計(jì)報(bào)告顯示,僅5年時(shí)間,手機(jī)網(wǎng)民由1.78億猛增至5億人,占總體網(wǎng)民81.0%,并保持穩(wěn)定增長(zhǎng)趨勢(shì),由此可知手機(jī)網(wǎng)民已成為穩(wěn)定增長(zhǎng)的龐大用戶群體。而手機(jī)屏幕尺寸和運(yùn)算能力的局限性,導(dǎo)致手機(jī)瀏覽器無(wú)法正常呈現(xiàn)、甚至無(wú)法打開針對(duì)PC設(shè)計(jì)的Web網(wǎng)頁(yè)。隨著微電子技術(shù)與移動(dòng)通信技術(shù)的迅速發(fā)展,該矛盾日益突出和尖銳。針對(duì)該問題,提出VWS技術(shù),以解決手機(jī)瀏覽器無(wú)法準(zhǔn)確、高效地顯示W(wǎng)eb網(wǎng)頁(yè)問題,從而提高用戶體驗(yàn)。 VWS技術(shù)從視覺角度標(biāo)識(shí)網(wǎng)頁(yè)中內(nèi)容塊的特征,之后基于最優(yōu)化理論,把網(wǎng)頁(yè)分割看作分組最優(yōu)化問題,將網(wǎng)頁(yè)分割為語(yǔ)義完整且適合手機(jī)顯示的子頁(yè)網(wǎng)。最后,選取特定子頁(yè)作為首頁(yè)推送給用戶,用戶可根據(jù)需要切換瀏覽各子頁(yè)。該技術(shù)創(chuàng)新地提出網(wǎng)頁(yè)預(yù)處理算法,將網(wǎng)頁(yè)內(nèi)容與樣式信息進(jìn)行融合,實(shí)現(xiàn)樣式信息充分、高效地利用；創(chuàng)新地依據(jù)人類視覺特征從六個(gè)維度描述內(nèi)容塊視覺特征,并定義內(nèi)容塊在視覺特征方面的相似度計(jì)算公式,之后設(shè)計(jì)神經(jīng)網(wǎng)絡(luò)直接確定公式中每個(gè)維度的權(quán)值,此權(quán)值直接確定法較專家經(jīng)驗(yàn)法真實(shí)、客觀,比傳統(tǒng)神經(jīng)網(wǎng)絡(luò)權(quán)值確定法高效、逼真；創(chuàng)新地將網(wǎng)頁(yè)分割看作分組最優(yōu)化問題,并基于最優(yōu)化理論中的Kruskal算法設(shè)計(jì)網(wǎng)頁(yè)分割算法。在確保手機(jī)正常顯示的前提下,實(shí)現(xiàn)各子頁(yè)中內(nèi)容塊間的相似度最大化,提高了各子頁(yè)中內(nèi)容塊間的語(yǔ)義的相關(guān)性與完整性。 ECs中含優(yōu)質(zhì)數(shù)字化學(xué)習(xí)資源高達(dá)125.64萬(wàn),隨著非正式學(xué)習(xí)理論在我國(guó)迅速流行加之手機(jī)的便捷性,越來越多的學(xué)習(xí)者希望通過手機(jī)訪問ECs網(wǎng)頁(yè)。因此,可以將VWS技術(shù)應(yīng)用于ECs中,并以ECs為實(shí)驗(yàn)對(duì)象驗(yàn)證VWS技術(shù)的可行性,借此解決ECs網(wǎng)頁(yè)在手機(jī)瀏覽器中的顯示問題,增加ECs的訪問渠道,從而促進(jìn)精品課程的建設(shè)與發(fā)展。實(shí)驗(yàn)中隨機(jī)選取100個(gè)不同的ECs網(wǎng)站,在每個(gè)網(wǎng)站中隨機(jī)獲取一個(gè)網(wǎng)頁(yè),采用VWS技術(shù)與VIPS技術(shù)分割得到的100個(gè)ECs網(wǎng)頁(yè),并對(duì)分割結(jié)果進(jìn)行定性實(shí)驗(yàn)與定量實(shí)驗(yàn)。分析結(jié)果表明,VWS技術(shù)可出色地完成Web網(wǎng)頁(yè)分割,實(shí)現(xiàn)針對(duì)PC端設(shè)計(jì)的網(wǎng)頁(yè)在手機(jī)中的正常顯示,并且具有較好的用戶體驗(yàn)。
[Abstract]:Statistical report CNNIC thirty-third China Internet development shows that only 5 years, mobile phone users jumped from 178 million to 500 million people, accounting for 81% of total Internet users, and to maintain a steady growth trend, so that mobile phone users have become huge user groups to stable growth. And limitations of mobile phone screen size and operation ability, leading mobile phone the browser can not be normal, even unable to open the PC design Web ". With the rapid development of microelectronics technology and mobile communication technology, the contradictions have become increasingly prominent and sharp. Aiming at this problem, put forward VWS technology to solve the mobile phone browser is not accurate, efficient display of Web pages, so as to improve the user experience.
VWS technology from the visual angle of web page content features identification block, then based on optimization theory, the web page segmentation as grouping optimization problem, the semantic web pages into complete and suitable for mobile phone display sub network page. Finally, select a specific sub page as the home page pushed to the user, the user may need to switch the browse each sub pages. Put forward the "technology innovation preprocessing algorithm, web page content and style information fusion, realization of information is full and efficient use of human visual characteristics; according to the creative description of content block visual features from six dimensions, and define the content block in the visual feature similarity formula. After the design of the neural network directly determines each dimension in the formula weights, the weights direct determination method is based on the expert experience real, objective, than the traditional method to determine the weights of the neural network, the innovation, realistic; Web page segmentation as grouping optimization problem and Kruskal algorithm design web page segmentation algorithm based on optimization theory. In the premise of ensuring the normal mobile phone display, the sub page content block similarity between the maximum, improve the relevance and integrity of each sub page content block between the semantic.
Up to 1 million 256 thousand and 400 with high quality digital learning resources in ECs, with the convenience of the informal learning theory in China's rapid and popular mobile phone, more and more learners hope to access the ECs page by mobile phone. Therefore, we can apply VWS technology to the ECs, and with ECs as the experiment on the feasibility as to verify VWS technology, to solve the the ECs page in the mobile phone browser display, increase access to the ECs channel, so as to promote the construction and development of excellent course. 100 different ECs sites were randomly selected in the experiment, random access to a web page at each site, 100 ECs pages using VWS technology and VIPS technology obtained by segmentation, and qualitative experiment the segmentation and quantitative experimental results. The analysis results show that the VWS technology can complete Web page segmentation, design and Implementation for the PC side of the web page in the mobile phone display properly, and has better use Household experience.
