EXPERIMENTAL RESULTS AND ANALYSIS

CONCLUSION

Abstract This paper propose the video information

collection architecture based on Web crawler after has analyzed the basic principles, key technologies and problems of the current crawler technology.

The system framework divided to two parts. The background part mainly manage Web crawler; Foreground part mainly view and artificial secondary correct the video semantic information which the crawler has collected.

WEB CRAWLER TECHNOLOGIES

The basic principles of Web crawler

Web crawler, also known as “Spider”, is a computer program which traverses the information on the Internet based on default condition.

• PageRank “PR”

ANALYSIS THE VIDEO SEMANTICACQUISITION SYSTEM FRAMEWORK AND

PRINCIPLES BASED ON WEB CRAWLER

Principle of the background

Principle of the foreground The user choose the most similar

semantic item as input keywords according to the similar semantic which the system listed, through inputting appropriate keyword in front-end.

This operation can improve the accuracy and reasonableness of semantic library which we have constructed.
