  1. 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。
  2. How to : use regular expressions to extract data fields

    如何：使用正則表達式提取數據欄位
  3. 4. an ica and 2d ehmm based method is proposed to extract the feature of facial expressions. ica is used to produce the independent observation vector of ehmm

    這種方法利用ica提取人臉表情差分圖像塊的獨立特徵作為ehmm的觀測向量，然後通過2dehmm對這些獨立特徵進行建模。
  4. The extensive pattern - matching notation of regular expressions allows you to quickly parse large amounts of text to find specific character patterns ; to extract, edit, replace, or delete text substrings ; or to add the extracted strings to a collection in order to generate a report

    正則表達式的全面模式匹配表示法使您可以快速分析大量文本以找到特定的字元模式；提取、編輯、替換或刪除文本子字元串；或將提取的字元串添加到集合以生成報告。
