Considering the high cost to label the training data manually during the experiment , this thesis applies some active learning algorithms to the new inductive algorithm above mentioned , and use the active technique to select the optimal worth examples for uses to label , 考虑到训练数据的手工标记成本很高,本文将主动学习的一些算法应用到上述新提出的归纳学习算法中,用主动学习算法来选择实用价值最高的信息来让用户标记,由此可有效地减少由于用户盲目性而产生的过多的手工操作。
Most of the developed countries are attaching much importance to education reformation , which calls for the reformation of fundamental education curriculum as the core . in our country , new curriculum reformation especially emphasizes active learning attitude , cooperation , problem solving , information gathering and synthesizing , and utilizing high - tech tools , etc . in new curriculum , the emphasis on integrative and interdisciplinary learning happens to share the same view with project - based learning 许多发达国家都非常关注以基础教育课程改革为核心的教育改革，我国的新课程特别强调“形成积极主动的学习态度” ， “倡导学生主动参与、乐于探究、勤于动手” ， “培养学生收集和处理信息的能力、获取新知识的能力、分析和解决问题的能力以及交流与合作的能力” 。
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系统分析与设计过程中所做的创新性的尝试主要有以下几个方面：实现了基于用户兴趣的用户模型，该模型通过与用户的交互(主动交互和被动交互) ，不断地接收用户的兴趣和推测用户的兴趣，积累用户信息需求的偏好，实现自适应的检索；提供了一种基于人机交互的反馈方法，对用户在结果呈现界面上的操作进行了归纳总结，设计了用户操作捕获算法， “隐性地”学习用户兴趣和偏好的变化；提供了一种用户需求挖掘的方法，对用户已确定的信息做进一步的主题挖掘，由此推测或预测用户同一兴趣的不同表述方式或者挖掘出用户新的或未表达出来的兴趣；在上述工作基础上提出了一套完整的基于用户兴趣的个性化网络信息检索的解决方案，该方案以用户兴趣模型为中心，以机器学习(主动学习和被动学习)和数据挖掘为手段，辅以网络机器人，具有很强的可行性和实用性。
We propose to select these samples to reduce the amount of sentences in the training data . now the major approaches of sample selecting are based on active learning method which selected samples by parser itself . but this method closely relate parsing model 目前国内外面向句法分析的样本选择大多采用主动学习的方法,这种方法的思想是让句法分析器自己决定什么样的句子应该作为它的训练样本,但是这种方法同句法分析模型密切相关,选出来的句子有可能会受到模型的影响。
These principles assert that good practice in undergraduate education , ( 1 ) encourages student - faculty contact , ( 2 ) encourages cooperation among students , ( 3 ) encourage active learning , ( 4 ) gives prompt feedback , ( 5 ) emphasizes times on task , ( 6 ) communicates high expectations , ( 7 ) and respects diverse talents and ways of learning 这七条对策包括鼓励师生互动，鼓励学生之间相互合作，鼓励学生主动学习，对学生的学习给予及时反馈，合理安排学习时间，时学生给予较高的期望，尊重学生之间的差异及其不同的学习方式等。
A good learning mechanism will be helpful for effectively transferring knowledge . the part mainly illustrates six factors of learning mechanism : system thinking ; improving mental model by organization learning each other ; cultivating relation capital ; the atmosphere of learning each other ; the inner - active learning ; the transition and innovation of knowledge 本章主要对构成学习机制的六个要素进行了详细的阐释，这六个要素是树立系统思想；通过组织学习改善心智模式；建立关系资本；相互学习的环境氛围；学习的互动性；实现知识的转化与创造。
Through constructing chemistry teaching resources web which specially aims to vocational school , the students continually find , analyze and resolve problems during participation , and then cultivate active study attitude , study initially and form information literacy to an extent ; moreover , learning space of the students is enlarged effectively by extending learning resources , and active learning and cooperation learning are improved . learning is " social negotiation " and " individual construction " in the active participation is fully explained 通过构建针对职业中学的化学教育资源网，让学生在参与的过程中，不断提出问题、分析问题、解决问题，养成积极的学习态度，自主进行学习，并形成了一定的信息素养；而且通过拓展学习资源，有效地扩展了学生的学习空间，促进了学生的主动学习、协作学习，充分说明学习就是“社会协商” 、学习就是积极参与中的“个体建构” 。
The development can be indicated by the following : a ) intelligen ce ability , operating ability and other abilities have been developed to some extends , more potentiality has been shown ; b ) students have been turned away from the learning by being fed into active learning , learning through research and enjoying learning because they have been taught some proper learning methods ( 2 )学生掌握了合理得当的学习方式。由被动、单一的学习方式转向了主动参与、乐于探究，多样化的学习方式。培养了学生自主学习、探究学习、主动参与学习的能力；促使学生学会学习，使学生逐步从“学会”向“会学”转化。
On the foundation of deep research of scientific proof , it not only has important present significance and deep strategic significance for zhengzhou university to set up a first degree university in the whole country , but will also have active learning significance for the development of our country ' s higher education to creatively study these " three subjects " and solve the important contradictory question happened in the course of construction and development of university 在深入调研、科学论证的基础上，创造性地做好“三大课题”的研究工作，破解学校建设和发展中的重大矛盾和问题，这不仅对郑州大学创建全国一流大学具有重大现实意义和深远的战略意义，而且对我国高等教育的发展也将会有积极的借鉴意义。
