[Embodiment 4] FIG. 22 is a block diagram showing a configuration of an Internet search device according to a fourth embodiment of the present invention. In FIG. 22, the reference numerals 103 to 111 have the same configuration as that of FIG. 1 according to the first embodiment, but to be described again, 103 constitutes a sentence from the stored text information of the teletext. Word cutting means for cutting out words, 104 for word frequency counting means for counting the frequency of occurrence of the cut out words, 105 for similar word merging means for merging similar words, and 106 for counting word occurrence frequency information. Trend information management means that stores and manages according to the frequency of appearance, 107 is a search key input means that gives trend keywords to the homepage browser as a search key, 108 is a homepage browser for displaying the Internet homepage, 109 is on the Internet The Internet connection means for connecting, 110 is an information selection means for selecting and designating necessary information from the information displayed on the screen, and 111 is a monitor for displaying an image.

【0055】

The present embodiment differs from the first embodiment in that the reference numerals 116 to 118 exist, 116 is a television broadcast receiving means for receiving television broadcasts such as terrestrial waves and satellite waves, and 117 is a character. It is a teletext receiving means for receiving multiplex broadcasts, and 118 is a teletext storage means for storing the text information of the received teletext.

【0056】

The operation of the Internet search device of the fourth embodiment configured as described above will be described below with reference to the flowcharts shown in FIGS. 23 and 24.

【0057】

First, in Step D1, the text information of the teletext is input from the teletext receiving means 117 and stored in the teletext storage means 118. FIG. 25 is an example of teletext, which is one content 22 of teletext. The teletext storage means 118 has a large number of contents 22 as described above. In Step D2, the content 22 is read from the teletext storage means 118 into the memory.

【0058】

Steps D3 to D7 are processed by the cooperation of the word appearance frequency counting means 104 and the trend information management means 105. In Step D3, a word keyword is cut out from the content 22 read in Step D2, and in Step D4, it is determined whether or not the word keyword already exists in the word keyword table. When the word keyword is cut out for the first time, it does not exist in the word keyword table yet, so proceed to Step D5 and add it to the word keyword table as a new keyword. This word keyword table is set as common to the word appearance frequency counting means 104 and the trend information management means 105. As for the method of cutting out words, various methods have been proposed in the world of natural language processing, and any of them may be used.

【0059】

If it is added to the word keyword table as a new keyword in Step D5, or if the extracted word keyword already exists in the word keyword table, proceed to Step D6 and give the word keyword a point as the frequency of appearance. give away. That is, the count value of the word keyword is incremented by 1. Next, the process proceeds to Step D7 to determine whether or not the content 22 that has not yet been read by the CPU exists in the teletext storage means 118 in this routine, and the reading / counting processing for all the contents 22 has not been completed. If so, return to Step D2 and repeat the same process. As described above, the number of occurrences of the word name is counted from all the contents 22 stored in the teletext storage means 118.

【0060】

Subsequently, in Steps D8 to D11, the similar word merging means 105 checks for similar word keywords. This is to prevent, for example, "Aleph" and "Aleph" from being treated as different words, although they represent the same thing. Since the procedure for merging similar words is the same as Steps A8 to A11 in the first embodiment, the description thereof will be omitted.

【0061】

In Step D12, the trend information management means 106 sorts the word keywords in the word keyword table according to the points, that is, the order of appearance frequency, and based on the result, the trend word information as trend information is displayed on the monitor screen 111 in the order of appearance frequency in Step D13. indicate. Words that appear more frequently can be said to be the current trend. FIG. 26 is a display screen 23 of the trend word displayed on the monitor screen 111. The trend ranking number and the trend word are displayed as a pair in descending order from the one with the highest trend ranking.

【0062】

The steps after Step D14 are the same operations as Step A14 to Step A19 of the first embodiment. That is, in Step D14, the user selects one trend keyword from the trend word display screen 23. In StepD15, the Internet connection means 109 connects to the search engine, and the homepage browser 108 displays the search engine on the screen. Screen 24 in FIG. 27 is a screen connected to a search engine. Next, in Step D16, the search key input means 107 inputs the trend keyword selected in Step D14 as the search key as the search key of the search engine to perform a search. On screen 24, this is the case when "Matsushita Electric" is selected as the search key on screen 23. In Step D17, the result of this search is displayed on the monitor 111. Screen 25 of FIG. 28 is a display example of search results.

【0063】

On this screen 25, the user selects the desired URL from the URLs listed on the screen 25 as Step D18. Then, the homepage browser 108 and the Internet connection means 109 connect to the URL specified by the user, and display the homepage of that URL in Step D19.

【0064】

According to the Internet search device of the fourth embodiment, the trend keywords obtained from the teletext are displayed in a list in descending order of appearance frequency on the screen 23, so that the trend topics can be easily found in the present world, and further, they are displayed. It is possible to obtain and display the location of more detailed information on the topic on the Internet by automatically searching.

【0065】

In counting trend keywords, it is preferable to perform merging of similar words in Steps D8 to D11 by the similar word merging means 105 in the fourth embodiment because the effect of reducing redundancy in the keyword extraction result can be obtained.

【0066】

Further, in the fourth embodiment, when a keyword is selected on the screen 23 of FIG. 26, the search is started by the keyword, but the content including the selected keyword may be displayed before the search is started. FIG. 29 shows the situation, and screen 26 shows the content including Matsushita Electric when Matsushita Electric is selected on the screen 23. On screen 26, the words that indicate the top trends as trend keywords are surrounded by squares (Matsushita Electric, Multimedia, Hewlett-Packard Company). In this case, when the user selects the trend keyword surrounded by these rectangles, the search is started as shown in the screen 24 shown in FIG. 27.

[Effect of the invention]

According to the Internet search device according to the present invention, the frequency of appearance of trend-related elements (for example, main performers, program contents, or words cut out from the latest news) from text information, program information, or teletext information. Since the Internet is searched by the trend keywords that appear frequently, it is possible to easily find the information related to the elements related to the trend that is popular in the world from a large amount of information on the Internet. it can.
