1. states the problem and the technical domain states and compares the results with the results of the related study It provides a clear definition and its importance of keyphrases for documents, then it carries out the problem. Using visualization technology to collects data to correct balance of challenge and difficulty for developers.

2. Keyphrase is strong method to … the factors which influence the performance of Kea. has been mentioned at both introduction, also a concise content structure. It highly summarized what the paper is about. Then it compares the results carried out in two algorithms: Kea and GenEx, then it investigates two ways to optimize the Kea algorithm. Two factors are caused by achieving the purpose (network transmission costs and response time variability. used for evaluating the effects of adopting Extreme Programming methodology which was performed at a company.

3. …., we can get better results of keyphrases from Kea. More and more affordable high-end mobile devices available in the market. Consumers highly care about mobile device battery life It tells the reason to choose a particular online storage service provider as their focus.

4. distinguish whether the subject of this paper is of interest to them or not. The XP-am is used to distinguish whether a development team has adopted XP’s core values from different stages.

5. To perform that how different visualization’s immersion factor to impact game and there are four types: Describes an implications about this research as well as some benefits, then gives the boundary and possible modification. Can help visualization researchers to shape and guide in the right direction. Two approaches, which are keyphrase assignment and keyphrases extraction, are introduced to the problem.

6. It also evaluates in detail how long these files can be stored and how quickly they can be updated to Dropbox after the original file published. when the bus will arrive, when to arrive at bus stops is timesaving.

7. Preposition which is used at changing website content. demand of information

8. informality we hope to carry out they wish to change because we want to do this evaluation in the future
