In fact, the knowledge database is an experiential specialist system, which includes library classification, thesaurus, concordance of class number with descriptor, synonymous dictionary, keywords lists, stop - words lists, etc. after determining the indexing data of web pages, the method of weighted word frequency, which combined with statistical algorithms, is adopted to exercise the subject indexing of chinese web pages
在確定網頁基本信息標引源的基礎上，中文網頁主題標引運用了基於詞頻的統計加權法；通過與分類號?主題詞對應庫主題詞串的詞面相似度計算，進一步完成中文網頁的賦號標引，即分類標引。And, an algorithm for constructing lexical chains based on hownet knowledge database is given
通過計算詞義相似度首先構建詞匯鏈，然後結合詞頻與區域特徵進行關鍵詞選擇。The first part of the paper is designing the testing project for grounding resistance and insulation resistance in a new way. using 16bits ad converter with programmable control amplifier replaced the way which used changing resistance to change measure range. lt is not only improved testing precision and develop the system expediently, but also reduced the area of the circuit boardwith the new way. in order to make the electric implement safety testing system have upstanding expansibility, the software and hardware of the system adopted the modularization design. adopted mcu atmegal28 as a master mcu which control mmi, realtime clock and communication with slaver mcu. atemga8 as the slaver mcu to realize testing function. so it is easy to add or reduce the testing project. the testing implement system has been developed successfully, and the comments for the system is that it has high precision, high expansibility and easy maintain. but considering the electric implement system should have intelligence and humanity abi lity. so this paper bring forward a scheme of electric equipment safety testing embedded system with speech control. after introduce the basic theory of speech recognition, the paper expatiate the characters of this system. the system is a noise conditon, not special people, small glossary, insulation word system. with these characters design the speech recognition as fellow. utilizing cross zero ratio and short energy to ensure jumping - off point and end point ; adopting mfcc as the character parameters of speech recognition ; the character parameters than be recognized by dtw. in order to ensure the credibility of this project, first realized by matlab in computer
在介紹了語音識別的基本原理后，闡述了本系統的特點：本系統是一個噪聲環境下非特定人、小詞匯量、孤立詞的語音識別系統。根據本系統的這些特點設計了如下語音識別方案：利用過零率和短時能量相結合的方式確定語音端點；採用mel頻率倒譜系數（ mfcc ）作為語音識別的特徵參數；得到的特徵參數最後通過動態時間規整（ dtw ）的模式識別方法進行識別。為了確保本系統實現方案的可靠性，首先通過計算機利用matlab軟體來模擬，在演算法模擬實現后又進一步增加環境的復雜性：加上較大的環境噪聲、突發性的噪聲等，再通過修改參數、修改參考模板、兩級識別等各種提高語音識別精度的方法來提廣東工業大學工學碩士學位論文高識別率。According to the statistical characteristic of noun phrases, we used an iterative re - evaluation algorithm for high - frequency noun phrases, and our metdhod for low - frequence noun phrases is similar to the algorithm for low - frequence content word. this method can take into account the alignment information on the whole, and acquire the result with high coverage rate
名詞短語的對應。本文根據名詞短語的統計特徵，對高頻名詞短語採用迭代重估演算法；對低頻短語，則採用類似於低頻實詞的對應方法。這樣就能夠從整體上把握對應信息，並使結果具有很高的覆蓋率。On the base of reviewing kinds of statistical parameter, we developed a hybrid statistical technique adapted to chinese - english parallel corpora for the high - frequence content words, and adequately used dictionary information for the low - frequence content word. at last, we used the competitive linking algorithm and achieved the better result
在詳細考察各類統計參數的基礎上，對高頻實詞提出了適合於漢英兩個不同體系語言的一種混合的統計方法，而對低頻實詞則充分利用詞典獲取對應信息，最後採用一種綜合的基於競爭鏈接的對應演算法，取得了較好的效果。分享友人
