The invention relates to a text searching system for searching web pages according to keyword and classification data provided by a user. The text searching system comprises a computer having a memory and a processor, a text data file having text data of web pages, a text index file having keyword searching data for searching keywords, a classification index file having classification data, and a searching program for searching text data which are matched with user provided keyword data and user provided classification data.
Description
Text searching system for searching web pages according to a keyword and classification data provided by a user BACKGROUND OF THE INVENTION
1. Field of the Invention The invention relates to a text searching system, and more particularly, to a text searching system for searching web pages according to a keyword and classification data provided by a user.
1. Field of the Invention The invention relates to a text searching system, and more particularly, to a text searching system for searching web pages according to a keyword and classification data provided by a user.
2. Description of the Prior Art As the number of web pages on the Internet increases, a searching system becomes necessary for searching the myriad of web pages for specific information.
Please refer to Fig.l. Fig.1 is a functional block diagram of a prior art searching system 10. The searching system 10 comprises a computer (not shown) , a text data file 16, a text index file 20, and a searching program 24. The computer comprises a memory 12 for storing programs and data and a processor 14 for executing the programs stored in the memory 12. The text data file 16, text index file 20, and searching program 24 are stored in the memory 12. The text data file 16 has text data 18 of web pages of a plurality of world wide web sites. The text index file 20 has keyword searching data 22 for searching keywords contained in the text data 18 of each of the web pages of the text data file 16. The searching program 24 is used for searching the text index file 20 according to keyword data provided by a user so as to find text data 18 of the all web pages having the user provided keyword data in the text data file 16.
Please refer to Fig.2. Fig.2 is a perspective diagram of the keyword searching data 22 in Fig.l. The keyword searching data 22 of the text index file 20 is built according to the text data 18 of the text data file 16. Each keyword searching data 22 has a keyword 21 and address data 23 of the keyword 21 in all web pages. As shown in Fig.2, the address data of the keyword "world" in all web pages are al, a2, a3...; the address data of the keyword "world wide web" in all web pages are cl, c2, c3. . . . When the user inputs a keyword, the searching program 24 searches the text index file 20 according to the keyword provided by the user to find the keyword searching data 22 corresponding to the keyword for getting the address data of the keyword in all web pages . Finally, the text data file 16 is used for transmitting the text data 18 of all web pages having the keyword to the user.
Because the prior art searching system 10 uses a keyword for searching web pages, the text data of all web pages containing the keyword are returned. This takes an excessive amount of time to transmit. In searching for the web pages within a specific classification, the searching system 10 transmits the text data of all the web pages containing the keyword to the user but most of the transmitted web pages are not well matched with the user provided classification.
Therefore, more time must be spent searching and transmitting.
For example, if the user wants to search for web pages of movies containing references to "tornado", the searching system 10 will transmit the text data of all web pages containing the word "tornado" to the user. However, these transmitted web pages will include irrelevant pages concerning unrelated topics such as meteorology, history, and news . Therefore, more time must be spent manually selecting the pages that are actually pertinent.
SUMMARY OF THE INVENTION
It is therefore a primary objective of the present invention to provide a text searching system for searching web pages according to a keyword and classification data provided by a user to solve the mentioned problem.
Briefly, in a preferred embodiment, the present invention provides a text searching system comprising:
