will gradually decline, as shown in Figure 11a,b. When the average precision of the top-3 and top-4 recommended projects is 15, there will be a slight turn; however, the top-5 recommended projects will show a trend of smooth decline, as shown in Figure 11c. In short, a large recommendation group will lead to higher-quality recommendation; nevertheless, it also means that it will take more time to complete the operation on the computer. Hence, there is a give-and-take relationship between output quality and processing time. According to the experimental results, the quality of the top-5 recommended projects is relatively high. System effectiveness experiment 1 first researches the system's effectiveness and various function tests. This paper uses the comparison table for LBSs, as proposed by [PERSON] [31], and classifies the proposed 12 items into location positioning, hardware device, application management, and system presentation for a comparison. This experiment indicates that a sound information recommender system must conform to more verification conditions. Therefore, the information recommendation and value added service classes (underlined part) are added to the comparison table, as shown in Table 6. The object compared in this experiment is the LBS system developed by the government: Taiwan Food Map ([[http://www.foodmap.tw/FM.html](http://www.foodmap.tw/FM.html)]([http://www.foodmap.tw/FM.html](http://www.foodmap.tw/FM.html))). As the system quality matches this system, it is selected as the control group. The overall function's up-to-standard rate of this system is 87.5%, whereas the up-to-standard rate of the Taiwan Food Map, as developed by the government, is only 43.7%. The reason is because: (1) this system uses location information efficiently to provide a more accurate information service; and (2) with the support of LOD (linked open data), this system architecture not only uses the back end database more efficiently, it also provides users with more all-inclusive LBS. \begin{table}
