Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an information providing apparatus and a teletext receiving apparatus which can be used, for example, when processing character string data sequentially sent in time series.

[0002]

2. Description of the Related Art In recent years, a lot of information has been provided through communication and broadcasting. This information includes text information such as teletext in addition to video and audio information such as television and radio. Character information is ASCII code, J
Since it is represented by a character code that can be easily processed by a computer such as an IS code, it has the advantage that the provider can easily copy and reuse it. However, for humans, the copied and reused character information may be read many times, and it takes a lot of time to obtain only the information that the user wants to read at least, or a common topic is tracked. There is a problem that it is difficult to do. This problem becomes more serious considering that the information provided will continue to increase as the information society advances. For such a problem, it is conceivable to work on a technique for associating documents with each other by automatically interpreting document contents and filtering information. An example of such efforts is research on natural language processing in the field of artificial intelligence research. However, there are many problems to apply to practical problems such as large-scale dictionary information, grammatical information, etc., and difficulty in reducing the probability of misinterpreting document contents to a practical level. There are few applications.

On the other hand, in recent years, receiving devices for character broadcasting in which character codes are transmitted as broadcasting have been developed and sold, and the character information provided to the home is rapidly increasing. In teletext, since the form of information is text, the user can obtain the information by reading the text displayed on the television. However, in a teletext program, several pages are displayed for each screen, and it cannot be known in advance which page of which program contains necessary information. As a result, problems arise in that a large number of characters must be read in order to obtain the necessary information, and pages must be read in sequence while turning.

Conventionally, a keyword search technique has been put into practical use as a technique for detecting the topic commonality of document data. This technology targets academic papers and the like and extracts all papers that include a specific keyword. Behind the practical application of such technology, the interest of the searcher can be expressed by a combination of several keywords, and it is not the search based on the semantic content of the document such as natural language processing but the detection of a very short character string. May allow you to search relatively easily. For such a problem, it is possible to use such a keyword search technique.

[0005]

However, when the above-described keyword search technique is applied to a teletext program, what kind of keyword is used for the search first becomes a problem. This is because a searcher who has a clear search intention gives a keyword to the system when searching for articles, but it is not known in advance which topic the user of the teletext program will be interested in. In this case, there is a need for a technique for associating documents with each other by automatically extracting a keyword from a teletext program and storing the keyword together with the document.
In addition, when extracting keywords automatically, there is a feature that proper nouns are often used in, for example, news programs, and it is not possible to prepare a word dictionary in advance like the conventional natural language processing technology. Therefore, there is a need for a technique for automatically extracting keywords and associating documents with each other without using a word dictionary.

Further, regarding the filtering technique for providing the user with only completely new information, it is not enough to remove the document which is a full-text match with the previously input document. Similar to the above, there is a need for a technique of automatically extracting a keyword from a document, determining the similarity between documents, and providing only information on a completely new topic.

[0007] Further, although the teletext program is updated hour by hour, the content of the program has already been updated and it is impossible to refer to it, for example, when it is desired to know the current situation in news or the like. ing. Therefore, there is an increasing need for functions such as storing past program contents in text broadcasting, referring to information related to each other, and displaying only completely new information.

Further, the above technique is not limited to a teletext program but is generally used for character string data given by a character code in a time series. For example, in an electronic mail device using communication, it is also necessary to rearrange the reference structure between mails regarding a plurality of topics.

There is also a problem that the user watching the teletext cannot watch the television broadcast at the same time, and the screen of the teletext becomes too small to read the characters even if they try to use the sub-screen function at the same time. Exists. In this case, it is also necessary to have a technology for organizing the screen so that it is easy for the teletext users to see. Even when watching a TV broadcast at the same time using the sub-screen function, it is necessary to have a technology that divides the character string into easy-to-understand topics and edits and provides the document so that the character size is sufficient for reading. is there.

In view of such conventional problems, the present invention relates to, for example, a teletext receiving device, detecting the degree of content duplication from a plurality of character string data sequentially obtained in time series, and enormous amount of data. It is an object of the present invention to provide an information providing device and a teletext receiving device that allow a user to more easily track a specific topic or to know a new topic more quickly than in the past. .

It is another object of the present invention to provide a teletext receiving apparatus which enables a teletext user to arrange a teletext screen more clearly than ever before.

Embodiments of the present invention will be described below with reference to the drawings.

First, as an embodiment of the first invention, an information providing method and an information providing apparatus in consideration of the relation between unit information will be described.

FIG. 1 is a system configuration diagram of an embodiment of the first invention.

In FIG. 1, 1 is an input unit which is divided into predetermined units (blocks) and which receives input of character string data in which each character string is represented by a character code, and 2 is a unit associated with each other. Output part for displaying 3
Is a keyword storage unit for storing a unit and a keyword extracted from the unit as a pair, and 4 extracts a keyword included in each of the predetermined units from the character string data input from the input unit 1, The keyword extraction process 5 for storing a predetermined unit and the extracted keyword as a pair in the keyword storage unit 3 is performed by the unit and the keyword stored in the keyword storage unit 3 before the character string data is input. A duplicate keyword number calculation process for calculating the number of keywords that overlap with the keyword extracted in the keyword extraction process 4 for each pair, 6 is the predetermined unit and keyword storage based on the number calculated in the duplicate keyword number calculation process 5. Part 3
This is an associating process of associating with the unit stored in the above and outputting the associated unit to the output unit 2.

FIG. 2 shows a hardware configuration for executing the system configured as described above. 2 is basically the same as the configuration of a general-purpose computer system, and includes the input unit 1 described as a component of the system configuration shown in FIG.
The output unit 2 and the keyword storage unit 3 are provided. Figure 2
The same numbers are given to the same components as those of the system configuration of FIG. Figure 2
In FIG. 11, 11 is a VRAM that stores the data displayed on the output 2, 12 is a main storage device that stores programs and data for processing at the time of execution, 13 is an external storage device that stores programs and data, and 14 is External storage device 13
Is a CPU that transfers and executes the program stored in the main storage device 12.

The operation of the information providing method and the information providing apparatus in consideration of the relation between the unit information thus configured will be described with reference to the flowchart of FIG.

In step a1, character string data is input through the input unit 1. The input character string data is data divided into predetermined units as shown in FIG.
In FIG. 4, the character data divided into predetermined units is n
There is an individual. For example, an example in which the content of a sports newspaper is stored and input in units 1 to n for each article is considered. As another example, an example in which research papers in a specific field are stored and input in units 1 to n for each academic society can be considered. In the former example, the change in the record of a specific team in a certain tournament can be obtained as the related information, and in the latter example, the progress of the research on the research object can be obtained as the related information. In order to use it as an example in the description of the following steps, it is assumed that the latest news is input as data in units 1 to n for each article in step a1. Example of input data
Shown in This is created based on the data of the teletext currently being broadcast. The data in FIG. 5 is composed of 6 units, and the beginning of each unit is represented by the symbol *.

At step a2, one unit is extracted from the character string data input at step a1. When extracting one unit from the character string data, one unit is taken out in a predetermined order such as an input order. Therefore, by repeating step a2, there is no unit to be extracted from the input data. In this case,
As shown in the flowchart, the process proceeds to step a8.

In step a3, a keyword is extracted from the character string data of one unit extracted in step a2 in the keyword cutting process 4, and the unit and the extracted keyword are stored in the keyword storage unit 3 as a pair. Regarding the extraction of keywords, various methods have been conventionally studied in the natural language processing technology, and any method may be used. However, the ones that require a large storage capacity such as dictionary information will be a major obstacle in the realization, and there are many proper nouns when preparing news items and the dictionary information cannot be prepared in advance. In consideration of the above, in the present embodiment, a method of cutting out a keyword based on a difference in character type is used without using dictionary information. Specifically, it is cut out from a series of three or more kanji, numbers, or katakana. However, if a keyword that starts with a number when cut out is excluded from being treated as a keyword. For example, if the data extracted in step a2 is the unit 1 of the data shown in FIG. 4, “Democratic People's Republic of Korea”, “nuclear suspicion”, “US talks with high-ranking officials”, “US representative of Garucci” are extracted as keywords. Be done. In this way, when a keyword is cut out based on a difference in character type, a meaningless keyword is cut out depending on the data, but a part of the meaningless keyword is stored in the keyword storage unit 3 in step a5 described later. It is corrected by partially matching the keyword of the unit. Further, in step a3, even the same keyword as that already cut out is repeatedly cut out and stored.

At step a4, one unit of the character string data stored in the keyword storage unit 3 and the keyword pair are extracted. When fetching one pair from the keyword storage unit 3, each pair is fetched one by one in a predetermined order such as an input order. When all the units stored in the keyword storage unit 3 have been taken out by repeating step a4, the process proceeds to step a2 as shown in the flowchart. FIG. 6 shows an example of a unit / keyword pair stored in the keyword storage unit 3.

In step a5, the keyword extracted in step a3 in the overlapping keyword number calculation process 5 is compared with the unit keyword extracted in step a4 to calculate the number of overlapping keywords. For example, the keyword extracted in step a3 is "US-North Korean senior official consultation".
If "North Korea", "signing ceremony", and "nuclear problem" are found, and the keywords extracted in step a4 are "North Korea", "nuclear problem", "fuel rod", and "US-Korean high-ranking talks", duplication The key words to do are "US-Korea high-ranking officer talks" and "North Korea"
Get 3 for the "nuclear problem". However, in the present embodiment, when two keywords A and B that are not the same are extracted, and the keyword B is the part of the keyword A, and that part is longer than 50% of the number of characters of the keyword A, the keyword A Is replaced with the keyword B and counted as the same keyword. For example, if the two keywords “US-Korean senior official consultation” and “US-North Korean senior official consultation agreement” are extracted,
Replace the keyword "US-North Korean high-ranking official agreement" with the keyword "US-North Korean high-ranking official agreement" and count as the same keyword.

Steps a6 and a7 are executed in the association process 6. In step a6, it is determined whether or not the unit extracted in step a2 and the unit extracted in step a4 are related to each other based on the number of overlapping keywords calculated in step a5. In the determination method performed in step a6, the constant S representing the overlapping ratio is set in advance, and the constant S is set to the smaller one of the number of keywords extracted in step a3 and the number of keywords extracted in step a4. The number T multiplied by is compared with the number D of overlapping keywords calculated in step a5, and if D is larger than T, it is determined to be related, and step a7 is determined. Go to a4. For example, the keywords extracted in step a3 are “US-Korean high-ranking official discussion”, “North Korea”, “signing ceremony”, and “nuclear problem”, and the keywords extracted in step a4 are “North Korea”, “nuclear problem”, and “nuclear problem”. In the case of "fuel rod" and "US-Korean official consultation", the number of overlapping keywords "US-Korean official consultation", "North Korea" and "nuclear problem" is obtained in step a5. In this case, if the constant S is 0.5, T = 2 and D = 3, so that D> T holds and it is determined that there is a relation.

At step a7, the unit taken out at step a2 is associated with the unit taken out at step a4. Regarding the association between the units, a method of providing a field of a pointer pointing to another unit in each unit of the keyword storage unit 3 or a unit for storing a matrix that stores the presence or absence of the units as a value in the external storage device 13 Various methods can be considered, such as a setting method. In the present embodiment, as an example using the former method, the keyword storage unit 3 after association is shown in FIG.

At step a8, the output unit 2 displays the character string data input at step a1 by dividing it into predetermined units, and if there are other units associated with each unit, or Display sequentially. For example, the three associated units shown in FIG. 7 are displayed as shown in FIG. Regarding the switching of each screen, there are a method of accepting a predetermined operation by the user, a method of automatically switching after a lapse of a fixed time, and the like.

Next, an embodiment of the second invention will be described with reference to the drawings.

As an embodiment of the second invention, a teletext receiving apparatus to which an information providing method considering the relation between unit information is applied will be shown.

FIG. 9 is a system configuration diagram of an embodiment of the second invention. In FIG. 9, 21 is a teletext receiving unit for receiving teletext, 22 is a display unit for displaying an associated article, 23 is a channel storage unit for storing a channel of a predetermined program, 24 is an article and a keyword. A teletext keyword storage unit for storing as 25, a teletext receiving unit 21 for receiving a program of a channel stored in the channel storage unit 23 by the telecast receiving unit 21, and an article cutting process for cutting an article from the received program, 26 is a character A teletext keyword extraction process for extracting a keyword contained in the article cut out in the broadcast article cutout process 25 and storing the article and the extracted keyword as a pair in the teletext keyword storage unit 24, 27 is the above It was stored in the teletext keyword storage unit 24 before the program was received. Based on the number calculated in the teletext duplication keyword number calculation process 27, the teletext duplication keyword number calculation process 28 calculates the number of keywords that overlap with the keyword extracted in the teletext keyword extraction process 26 for each event / keyword pair. In the teletext associating process, the articles are associated with the articles stored in the teletext keyword storage unit 24 and the associated articles are displayed on the display unit 22.

FIG. 10 shows a hardware configuration for executing the system configured as described above.

FIG. 10 is basically the same as the configuration of a general-purpose computer system, and the configuration part of the hardware configuration of one embodiment of the first invention shown in FIG. 2 and the second configuration shown in FIG. Since the system is composed of the constituent parts of the embodiment of the invention, the same constituent parts are designated by the same reference numerals, and detailed description thereof will be omitted.

The operation of the teletext receiving apparatus with the information providing function, which takes into consideration the relation between the unit information configured as described above, will be described with reference to the flowchart of FIG. Further, since the present invention does not relate to the teletext receiving system itself, the teletext receiving unit 21 is included in the teletext receiving portion.
, And detailed description thereof will be omitted.

In step b1, the channel storage unit 23
Take one out of the channels stored in. When the program stored in the channel storage unit 23 is completely taken out by repeating the step b1, the process proceeds to step b9 as shown in the flowchart. The channels stored in the channel storage unit 23 are as shown in Table 1 below.

[0048]

[Table 1] When the data as shown in Table 1 is stored in the channel storage unit 23, 4ch and 02 # are taken out when step b1 is called for the first time. The reason for such a channel is that the program is specified by the channel number and the number with # in the current teletext. As an example of the channel stored in the channel storage unit 23, a channel in which a program of a specific genre is broadcast, such as a channel of a plurality of news programs and a channel of a plurality of sports programs, can be considered.

In step b2, in the teletext article cutout process 25, the teletext receiving unit 21 receives a teletext program according to the channel extracted in step b1. The content of the teletext program received in step b2 is temporarily stored in the main storage device 12 or the external storage device 13.

At step b3, articles are sequentially taken out from the teletext program received at step b2. When all the articles have been extracted from the program by repeating step b3, the process proceeds to step b1 as shown in the flowchart. An article here is a series of sentences that cover a specific topic, such as an article of a news program. However, in teletext news programs currently being broadcast, there are two articles on a teletext screen,
Since there is a case where one screen does not necessarily correspond to one article, such as when there are articles covering two screens, the process of extracting articles becomes complicated. It is also possible to retrieve an article by performing the same processing as step e3 in the embodiment of the fifth invention described later, but in this embodiment, one screen of teletext corresponds to one article for simplicity. Processing is performed as if it does.

In steps b4 to b9, the same processes as steps a3 to a8 in the first embodiment of the invention are performed. Steps b4, b5, b6, b7, b8,
b9 is step a3 of the embodiment of the first invention.
a4, a5, a6, a7, a8, and a display unit 22, a teletext keyword storage unit 24, a teletext keyword cutout process 26, a teletext duplication keyword number calculation process 27, a teletext association process 28,
Each article in the program received by teletext is first
It corresponds to the output unit 2, the keyword storage unit 3, the keyword extraction process 4, the duplicate keyword number calculation process 5, the association process 6, and one unit in the input character string data in the embodiment of the invention.

Next, an embodiment of the third invention will be described with reference to the drawings.

As an embodiment of the third invention, an information providing method and an information providing apparatus in consideration of whether or not the input information includes a new topic will be shown.

FIG. 12 is a system configuration diagram of an embodiment of the third invention. Since FIG. 12 has the same components as the system configuration diagram of the first embodiment of the present invention, the same components are designated by the same reference numerals and detailed description thereof will be omitted.
In FIG. 12, reference numeral 31 indicates whether or not there is a relationship between the unit in the character string data input by the input unit 1 and the unit stored in the keyword storage unit 3 based on the number calculated in the duplicate keyword number calculation process 5. In the new information management process, the former unit is regarded as new information when it is determined to be irrelevant, and only the new information of the character string data input by the input unit 1 is output to the output unit 2.

The hardware configuration for executing the system configured as described above is the same as the hardware configuration of the embodiment of the first invention shown in FIG. Therefore, detailed description is omitted.

The information providing method and the operation of the information providing apparatus in consideration of whether or not the input information configured as described above includes a new topic will be described with reference to the flowchart of FIG.

In steps c1 to c5, the same processing as steps a1 to a5 of the first embodiment of the present invention is performed. However, in step c4, when all the units stored in the keyword storage unit 3 have been taken out, the process proceeds to step c7 as shown in the flowchart.

Steps c6 to c8 are executed in the new information management process 31. At step c6, based on the number of overlapping keywords of the keyword extracted at step c3 calculated at step c5 and the keyword extracted at step c4, the relation between the unit extracted at step c2 and the unit extracted at step c4 is determined. Determine the presence or absence. This determination is performed by the same method as step a6 of the first embodiment of the invention. If the determination result is related, the process proceeds to step c2, and if it is not related, the process proceeds to step c4.

In step c7, the unit extracted in step c2 is regarded as new information and FIFO (First In Firs
Store (push) on the stack of (t Out). Since the unit stored in this stack is not similar to any of the units stored in the keyword storage unit 3, it can be regarded as new information.

In step c8, the unit stored in the stack in step c7 is displayed as new information in the output section 2. For example, among the units shown in FIG. 7, those not associated with each other are regarded as new information and displayed as shown in FIG.

Next, an embodiment of the fourth invention will be described with reference to the drawings.

As an embodiment of the fourth invention, a teletext receiving apparatus to which an information providing method in consideration of whether or not the inputted information includes a new topic is applied will be shown.
