Currently, content-based recommendation, collaborative filtering, knowledge-based recommendation are most widely used. However, it is difficult to just use one of them to solve all the problems like cold start, data sparseness, over-fitting etc. together. A hybrid recommendation model based on label propagation and VSM clustering is presented in this paper, which can avoid bias caused by a single algorithm and improve the recommendation system's validity, usability, and portability. After implementing and deploying our model in Maze system [1], we were pleased to discover some rules on how the thermal diffusion model and probability diffusion model could affect the quality of recommendation results and proved that our hybrid model can improve result precision by 47%.","PeriodicalId":264063,"journal":{"name":"2012 7th International Conference on Computer Science & Education (ICCSE)","volume":"74 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-07-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125618080","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In fact, the scientific college English teaching mode for “leaner autonomy” is not just the case at all. It is the product of modern high technology and the embodiment of the theory of “leaner autonomy” in college English teaching. What's more, with its unique course design and teaching management, it has to be based on those teachers who are skillful at computer network and software. For another thing, this teaching model is very necessary and even urgent for the scale and characteristic of Chinese current and even future college English teaching, especially it can make up for the weaknesses arising from our current family and school education. In addition, the education philosophy involved in this teaching model completely agrees with the ultimate goal of education - developing students' ability of learning autonomy.","PeriodicalId":264063,"journal":{"name":"2012 7th International Conference on Computer Science & Education (ICCSE)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-07-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115178252","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In the proposed algorithm, owning to the instability of the ad-hoc network, which is formed by the mobile terminals, the opportunistic networks are adopted to transmit messages. The most important messages are supposed to be transmitted first to improve the accuracy of application, while the least important ones should be deleted, aiming to reduce the using of network bandwidth and cache space. In the ERGLDP algorithm, the computation of the message priority that is different from the existing algorithms considers all the influential factors. In addition, the messages are transmitted and deleted based on their priority. To avoid the transmission collisions, a new medium access control (MAC) protocol is designed in this algorithm.","PeriodicalId":264063,"journal":{"name":"2012 7th International Conference on Computer Science & Education (ICCSE)","volume":"8 2","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-07-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131437936","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The simulation results show that the instability and morphology selection of dendrite are influenced by anisotropy strength. If the anisotropy coefficient is 0 or little, equiaxed dendrite will not bring. Under the same condition, the dendrite will grow faster with the increase of anisotropy coefficient. But if the anisotropy coefficient value (0.06) is over large, dendrite variation will appear, the simulation conclusion is consistent with theoretical predictions.","PeriodicalId":264063,"journal":{"name":"2012 7th International Conference on Computer Science & Education (ICCSE)","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-07-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128067008","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Then use Hellinger distance as the distance metric for document clustering and a new square-root cosine similarity for query information retrieval. This new similarity/distance also bridges between traditional tf_idf weighting to binary weighting in vector space model. Finally, we conduct a comparison on performance between this method and the one based on Euclidean distance and cosine similarity. And from the results, we clearly observe that the precision and recall are improved by using the sqrt-cos similarity.","PeriodicalId":264063,"journal":{"name":"2012 7th International Conference on Computer Science & Education (ICCSE)","volume":"33 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-07-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128126921","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

According to the results of subjective assessment, the comfortable matching and difference maps of hue and saturation were defined and the universal applicability of the maps was verified. The accurate rate of whether one stereoscopic image was comfortable according to the maps was more than 92%.
