viewing filter
解釋
觀察用濾片-
However, this does not take into account visual comfort ; for comfortable viewing of the sun, a filter with a luminous transmittance of 0. 0003 % ( shade number 14 ) is often preferable
然而，以上的計算並未考慮到觀測時的舒適程度.在考慮舒適程度后，建議使用0 . 0003 %透光率（相當於14號密度）的濾鏡作太陽觀測 -
The structure recognization of web table can be processed by two phases. first we need to filter out those non - genuine tables which is uesd not for relational information display but for creating any type of multiple - column layout to facilitate easy viewing. according to lots of observations to tables in web pages, the features are identified which best capture the characteristics of the genuine table compared to a non - genuine one, and then get the heuristic rules. based on these rules, algorithms are designed and implemented to evaluate the performance, as measured by ie evaluation metrics - recall, precision and f - measure. the result show that the performance of our algorithms is not less effectively than others
首先從紛繁復雜的web頁面中濾去那些用於控制頁面結構而不是表達有效數據信息的「假表格」 。本文通過大量的觀察，提取出識別真假表格的特徵信息，形成啟發式規則;在此基礎上設計並實現一系列演算法;最後通過傳統的信息抽取指標? ?召回率、準確率和f指數來衡量識別結果。實驗顯示，本文的演算法有較強的表格識別能力。
