In contrast with the measurement of backscattered ultraviolet solar radiation onboard satellites, ir radiance measurements in 9. 6m spectral channel at various instruments onboard meteorological / environmental satellites allow ozone estimates during both day and night. in this paper, we use ir radiance measurements within 9. 6 im spectral channels from moderate resolution spectral radiometer ( modis ) and advanced tiros operational vertical sounder ( atovs ) to retrieve total column ozone based on the operational retrieval system of national satellite meteorological center. for validating retrieval results, both ground based observation and total ozone mapping spectrometers ( toms ) ozone measurements are used and atovs retrieval results are corrected after the validation
本文利用美國noaa衛星上的先進的大氣垂直探測器業務系統（ atovs ）儀器和地球觀測系統衛星（ eos ）上的中解析度成像光譜儀（ modis ）上的9 . 6 m臭氧探測通道的輻射測值，在國家衛星氣象中心業務反演軟體系統基礎上，反演出了兩種儀器探測的大氣臭氧總量，並且利用中國五個常規臭氧觀測站的資料和美國研製的臭氧總量測繪光譜儀（ toms ）反演的臭氧資料對兩種反演結果進行驗證分析，對atovs反演結果進行了訂正。 -
During the procedure of system design and implementation, the author has made some innovative efforts such as : ( d establishing the user interest orientated model, the model receiving user interests continuously and conjecturing user interests by interaction with the user, accumulating user preferences in information demand, thereby achieving self - adaptive retrieval, ? roviding a feedback method which is based on the human - machine interaction, summarizing the user operations on the interface of result presentation, and designing an algorithm for capturing user operation behaviors, by which the changes in user interests and preferences can be learned potentially, ? ffering a method for user interest mining which can extract subjects of information confirmed by user, thereby conjecturing or predicting different kinds of expressions of the same interest or extracting the new interests or unexpressed interests, ? roposing a solution of personalized internet information retrieval based on the user interests in accordance with the above - mentioned work, the solution having very strong feasibility and practicality with taking user interest model as center, employing machine learning ( active learning and passive learning ) and data mining as tools, and being assisted with network robot,
Piirs系統分析與設計過程中所做的創新性的嘗試主要有以下幾個方面：實現了基於用戶興趣的用戶模型，該模型通過與用戶的交互（主動交互和被動交互） ，不斷地接收用戶的興趣和推測用戶的興趣，積累用戶信息需求的偏好，實現自適應的檢索；提供了一種基於人機交互的反饋方法，對用戶在結果呈現界面上的操作進行了歸納總結，設計了用戶操作捕獲演算法， 「隱性地」學習用戶興趣和偏好的變化；提供了一種用戶需求挖掘的方法，對用戶已確定的信息做進一步的主題挖掘，由此推測或預測用戶同一興趣的不同表述方式或者挖掘出用戶新的或未表達出來的興趣；在上述工作基礎上提出了一套完整的基於用戶興趣的個性化網路信息檢索的解決方案，該方案以用戶興趣模型為中心，以機器學習（主動學習和被動學習）和數據挖掘為手段，輔以網路機器人，具有很強的可行性和實用性。 -
After clustering of the documents, in the process of retrieval, we make a comparison between the retrieval words the users point out and cluster center of the documents, and as a result, achieve a cluster that is most similar to retrieval words. through the calculation of both the selected documents and those retrieval words, thence the retrieval range will be reduced, the efficiency of retrieval be increased, and the retrieval deviation be overcome to a certain extent
對文檔進行了聚類，在檢索的期間，對用戶提出的檢索詞先進行和每一類的類心比較，得到與之最近的類別，僅將屬于該類別中的文檔與用戶提出的檢索詞進行運算，從而縮小了檢索的范圍，提高了檢索的效率，也在一定程度上克服了檢索結果的偏差。 -
