Description

  The present invention relates to a technique for determining the consistency of information included in a search result of each information search service, which plays an important role in a system that summarizes and outputs search results of a plurality of information search services.

  Conventionally, information search services such as Web search, image search, and blog search have been used to know popular topics and current information. This information search service tends to increase in recent years as new search technologies and databases are developed and constructed. On the other hand, a user of an information search service can select and use an information search service for obtaining desired information as appropriate, and it is best to use which information search service among a wide variety of information search services. It was difficult to determine whether it was.

  Thus, there is known one that collectively outputs search results of a plurality of information search services obtained for an input search query (see, for example, Patent Document 1).

  The information search apparatus of Patent Document 1 is configured to acquire and output a union or common set of search results (URLs) of each information search service. Thereby, the information search apparatus can be controlled so that the same URL is not output redundantly when the same URL exists between the search results of each information search service.

Japanese Patent Laid-Open No. 2002-24265

  However, in the conventional information search apparatus, it is possible to determine whether or not the URL is duplicated between search results of each information search service, while determining the consistency of information displayed by the URL. The same information may be output repeatedly between search results of each information search service. Specifically, for example, for a search query “Yukio Hatoyama”, as shown in FIG. 1, information “Web document search”, “Wikipedia (registered trademark) basic information search” and “official page profile search”. When the search result of the search service is obtained, the information “birth date” and “birthplace” searched by “wikipedia (registered trademark) basic information search” and “official page profile search” are duplicated. Since the information is output, it is difficult to summarize and output the information included in the search result.

  The present invention has been made in view of the above problems, and an object thereof is an apparatus capable of summarizing and outputting information included in search results of a plurality of information search services, a method thereof, and a program therefor Is to provide.

An information consistency determination apparatus according to the present invention is an apparatus for determining the consistency of information included in search results of a plurality of information search services obtained for an input search query in order to achieve the above object. When the search query is input, a search result acquisition unit that acquires a search result searched by the search query for each information search service, and a search result of each information search service is acquired from the search result acquisition unit. Then, the degree of overlap between the information included in the search result of one information search service and the information included in the search result of another information search service is obtained , and the information set is selected in descending order of the obtained redundancy. And an information consistency determining unit that terminates the selection when the entropy of the word in the selected information is equal to or greater than a threshold and determines that the selected information is consistent.

In order to achieve the above object, the information consistency determination method of the present invention uses a computer to check the consistency of information included in the search results of a plurality of information search services obtained for an input search query. When the search query is input, the computer obtains a search result searched by the search query for each information search service, and uses the search result of each information search service. Once acquired, the degree of duplication between the information contained in the search result of one information search service and the information contained in the search result of another information search service is obtained , and a set of information is selected in descending order of the obtained degree of duplication. If the entropy of the word in the selected information is equal to or greater than the threshold, the selection is terminated, and it is determined that the selected information is consistent .

  Furthermore, the program of the present invention is for causing a computer to function as each means of the relational expression discriminating apparatus.

  Furthermore, the program of the present invention is for causing a computer to execute each process of the relational expression discrimination method.

  As a result, when a search query is input, the consistency between the information included in the search results of the plurality of information search services obtained for the search query is determined based on the degree of overlap between the information in each search result. Therefore, it is possible to determine whether or not to output all search results of each information search service based on the consistency between the information included in the search results.

  According to the information consistency determination device, the method, and the program of the present invention, it is possible to determine whether or not to output all search results of each information search service based on the consistency between information included in the search results. For example, when information such as “birth date” or “birthplace” is retrieved by a plurality of information retrieval services, “birth date” and “birthplace” retrieved by any one of the information retrieval services Only information such as “can be output. Therefore, duplication and consistency of information included in the search results can be controlled, and the information can be summarized and output.

FIG. 3 is a flowchart of information consistency determination processing. FIG. FIG. 5 is a diagram showing an overview of the processing result by the result acquisition unit, FIG. 5 is a diagram showing an overview of the processing result by the information consistency determination unit, and FIG. 6 is a diagram showing an overview of the processing result by the search result output unit.

  An outline of an information consistency determination apparatus and method according to the present invention will be described below with reference to the drawings.

  The information consistency determination device 1 of the present invention is a computer device mainly composed of a well-known CPU, and can be connected to display means such as a monitor, input means such as a keyboard, storage means such as a hard disk and memory, and a network. A communication device and the like (both not shown) are provided. As shown in FIG. 2, the information consistency determination device 1 of the present invention includes a search result acquisition unit 10, an information consistency determination unit 20, and a search result output unit 30.

  The search result acquisition unit 10 is a module that, when a search query is input using an input unit, acquires a search result searched by the search query for each of a plurality of information search services. As shown in FIG. 2, the search result acquisition unit 10 is configured to be accessible to a plurality of information search service servers 100, 200, 300 via a network such as the Internet. When a search query is input ( In step S1) of FIG. 3, a search result for the search query is requested to each information search service server 100, 200, 300. In this embodiment, the information search services 1, 2, and 3 are used as services “Web document search”, “wikipedia (registered trademark) basic information search”, and “official page profile search”, respectively.

  Each of the information search service servers 100, 200, and 300 includes specialized search units 101, 201, and 301 and search service databases (DBs) 102, 202, and 302, respectively. When a search query (for example, “Yukio Hatoyama”) is acquired from the search result acquisition unit 10, the search processing DB 102, 202, 302 is connected to the connected search service DBs 102, 202, 302. Specifically, with reference to FIG. 4, the specialized search unit 101 of the server 100 for the information search service 1 searches the search service DB 102 for a Web document including the acquired search query (“Yukio Hatoyama”). As shown in FIG. 4 (a), the title, URL, snippet, etc. of the retrieved document are extracted as retrieval results. Further, when the specialized search unit 201 of the server 200 for the information search service 2 obtains the search query (“Yukio Hatoyama”), as shown in FIG. 4B, attributes (for example, date of birth, Hometown) and attribute values are extracted from the search service DB 202 as search results. Further, upon obtaining the search query (“Yukio Hatoyama”), the specialized search unit 301 of the server 300 for the information search service 3 obtains an attribute (for example, date of birth, Hometown) and attribute values are extracted from the search service DB 302 as search results. In this embodiment, the search results are extracted in the XML format, but other formats may be used.

  Then, the specialized search units 101, 201, and 301 transmit respective search results to the search result acquisition unit 10. On the other hand, when the search result acquisition unit 10 acquires the search result from each of the information search service servers 100, 200, and 300 (step S2 in FIG. 3), the search result of each information search service is transmitted to the information consistency determination unit 20. To do.

  Next, an overview of the information consistency determination unit 20 will be described. When the information consistency determination unit 20 acquires the search result of each information search service from the search result acquisition unit 10, the information consistency determination unit 20 includes the information included in the search result of one information search service and the search results of other information search services. It is a module that obtains the degree of duplication between information and determines the consistency between information of each search result based on the degree of duplication.

When the information consistency determination unit 20 acquires the search result of each information search service from the search result acquisition unit 10, the information consistency determination unit 20 includes the information included in the search result of one information search service and the search results of other information search services. The degree of overlap is calculated based on the number of words included in each piece of information in common (step S3 in FIG. 3). In this embodiment, the degree of duplication is calculated for each piece of information included between the <result> tag and the </ result> tag of each search result. Specifically, when determining the degree of overlap between the information X 1 included in the search result of one information search service and the information X 2 included in the search result of another information search service, the information X 1 and the information X 2 is COM (X 1 , X 2 ), and the minimum number of words for each of information X 1 and information X 2 is MIN (X 1 , X 2 ). (1).

Further, when the maximum value of the number of words of information X 1 and information X 2 is MAX (X 1 , X 2 ), the degree of overlap can be determined by the following equation (2).

Further, when X 1 is used as the number of words of information X 1 and X 2 is used as the number of words of information X 2 , the degree of overlap can also be determined by the following equation (3).

  The information consistency determination unit 20 determines the consistency of each piece of information after calculating the degree of duplication using any one of the above (1) to (3) (step S4 in FIG. 3). Specifically, the information consistency determination unit 20 compares each obtained redundancy with a first threshold value stored in advance in a storage unit (not shown) such as a hard disk or a memory, thereby The consistency between the search result information is determined. In the present embodiment, it is determined that there is consistency between pieces of information when the degree of overlap is equal to or greater than the first threshold.

Here, as a specific example, a case will be described in which “1” is set as the first threshold value and the above formula (3) is used as a calculation formula for the degree of overlap. In this case, there are two information words “birth date” and “S22 / 02/11” included in the wikipedia (registered trademark) basic information search shown in FIG. 4B. . In addition, the information words “birth date” and “birth date” and “S22 / 02/11” included in the official page profile search shown in FIG. Therefore, since the words and the number of words included in each information are the same, X 1 = X 2 = COM (X 1 , X 2 ) = 2, and the degree of overlap between the information is 1. Since the degree of overlap is equal to or greater than the first threshold, information “birth date” included in the wikipedia (registered trademark) basic information search, information “birth date” included in the official page profile search, and Are determined to be consistent.

  If the information consistency determination unit 20 determines that there is consistency between the pieces of information, the information consistency determination unit 20 selects one of the pieces of information as information to be output to the search result output unit 30 described later. In the present embodiment, the date of birth information included in the wikipedia (registered trademark) basic information search is selected.

  As described above, by performing the processing of step S3 and step S4 for each piece of information included in all the acquired search results, among the search results of each information search service shown in FIG. 5A, FIG. The search result shown in is selected. In this case, the date of birth and birthplace information included in the official page profile search is selected because it is consistent with the date of birth and birthplace information included in the wikipedia (registered trademark) basic information search. Absent.

  Next, an outline of the search result output unit 30 will be described. The search result output unit 30 is a module that outputs information on each search result selected by the information consistency determination unit 20.

  When the search result output unit 30 acquires the selected search result from the information consistency determination unit 20, the search result output unit 30 outputs the search result to a display unit (not shown) such as a monitor in a preset output format (see FIG. 3 step S5). More specifically, the search result output unit 30 indicates that the display order of the information search service is “first: Web document search, second: wikipedia (registered trademark) basic information search”. 6, the search result of the Web document search service is output in a preset output format and the search result of the Wikipedia (registered trademark) basic information search service is preset as shown in FIG. Output in the specified output format. Further, in the present embodiment, as shown in FIG. 6, the search results of each information search service are displayed side by side, but may be displayed side by side or displayed in a grid.

  In this way, when a search query is input, the consistency between the information included in the search results of the plurality of information search services obtained for the search query is the degree of overlap between the information of each search result. Therefore, it is possible to determine whether or not to output all search results of each information search service based on the consistency between pieces of information included in the search results.

  In the above flow, when it is determined that there is consistency between the pieces of information, one of the pieces of information has been selected as information to be output to the search result output unit 30, but is consistent with each other. It may be configured such that only a set of information determined to have the property is selected. In this case, consistent information in the search results of each information search service can be output as the search results. On the other hand, when only a set of information determined to be inconsistent is selected, a wide range of information with no bias can be output as a search result.

  As described above, in the above embodiment, whether or not to output all search results of each information search service can be determined based on consistency between information included in the search results. ”And“ Birthplace ”are searched by multiple information search services, only the information such as“ Birth date ”and“ Birthplace ”searched by any one of the information search services is output. be able to. Therefore, duplication and consistency of information included in the search results can be controlled, and the information can be summarized and output.

  In addition, a search result output unit 30 that outputs information of each search result selected by the information consistency determination unit 20 is provided, and the information consistency determination unit 20 searches for each information search service acquired from the search result acquisition unit 10. Since the information to be output to the search result output unit 30 among the results is selected based on the consistency between the information of each search result, the information selected based on the consistency can be output, and the information included in the search result Can be summarized and output.

  Furthermore, since the information consistency determination unit 20 determines the consistency between pieces of information of each search result based on the degree of duplication and the first threshold, the consistency can be easily determined. It is possible to improve the processing efficiency related to the determination process.

  Furthermore, the information consistency determination unit 20 is based on the number of words commonly included between the information included in the search result of one information search service and the information included in the search result of another information search service. Since the degree of duplication is obtained, the degree of duplication can be easily obtained, and the processing efficiency relating to the calculation process of the degree of duplication can be improved.

  The information consistency determination apparatus and method according to the second embodiment of the present invention will be described below. This embodiment is different from the first embodiment in that the information consistency determination unit 20 determines the consistency between information of each search result based on the degree of duplication and the entropy of words included in each information. There is in point to do. Since other configurations and operations are the same as those in the first embodiment, only differences will be described here.

The information consistency determination unit 20 of this embodiment determines the consistency between pieces of information (step S4 in FIG. 3) after calculating the degree of duplication between pieces of information in each search result (step S3 in FIG. 3). In this case, the information consistency determination unit 20 selects information sets of each search result in descending order of redundancy, and calculates the entropy of the words included in the information every time the information set is selected. Then, the information consistency determination unit 20 repeats the selection of the information set until the entropy value becomes equal to or greater than the second threshold value stored in the storage unit (not shown). Here, if the total number of words in the already selected information is m, the number of different words in the selected information set is n, and the total number of words n is Xn, the entropy H can be obtained by the following equation (4). .

Here, the value of entropy H increases as the number of words increases. Therefore, the value of entropy H changes from a low value to a high value by selecting a set of information in descending order of redundancy. In addition, when the value of the entropy H becomes equal to or greater than the second threshold, the information consistency determination unit 20 ends the information set selection process. In this case, the information consistency determination unit 20 determines that there is consistency among all pieces of information selected until the selection process ends. Then, the search result output unit 30 outputs the information selected by the information consistency determination unit 20 (step S5 in FIG. 3).

Note that when the entropy H is obtained, the information consistency determination unit 20 obtains a difference or ratio from the entropy H ′ stopped x (x> 0) times before the entropy H. Alternatively, the consistency between the pieces of information may be determined by comparing the ratio with a predetermined threshold.

  As described above, in the above embodiment, the information consistency determination unit 20 determines the consistency between pieces of information of each search result based on the degree of duplication and the entropy of words included in each information. Information can be output, and the consistency of the output information can be further improved.

  The information consistency determination apparatus and method according to the third embodiment of the present invention will be described below. This embodiment differs from the first and second embodiments in that the information consistency determination unit 20 is included in the information included in the search result of one information search service and the search results of other information search services. Among the words included in each piece of information, the degree of duplication is obtained based on the number of words associated with the same semantic class in the thesaurus. Since other configurations and operations are the same as those in the first and second embodiments, only the differences will be described here.

  The storage means (not shown) of this embodiment stores Japanese vocabulary large dictionary data as a thesaurus. Note that what is automatically or semi-automatically estimated from a large-scale text corpus may be used as the thesaurus.

  When the information consistency determination unit 20 of the present embodiment acquires the search result of each information search service from the search result acquisition unit 10, the information contained in the search result of one information search service and the search of another information search service The degree of overlap with the information included in the result is calculated (step S3 in FIG. 3).

  Here, the information consistency determination unit 20 performs a process of associating a word included in each information with a thesaurus semantic class stored in a storage unit (not shown). A known technique can be used for this association process. For example, when the search result of each information search service shown in FIG. 7A is obtained, the word included in the information of each search result and the semantic class of the thesaurus are shown in FIG. Corresponding as shown in b). In this case, the words “date of birth” and “date of birth” are associated with the semantic class “class 1”, and the words “place of birth” and “place of birth” are “class 2”. Is associated with the semantic class.

Next, the information consistency determination part 20 calculates | requires duplication using one of the above-mentioned formulas (1) to (3). In the present embodiment, COM (X 1 , X 2 ) in the expressions (1) to (3) is associated with the same semantic class in the thesaurus among the words included in the information X 1 and the information X 2. It represents the number of words. When using the above example, among the words included in information X 2 of "birth date" information X 1 and "birth date" that were associated with the same semantic class (class 1) in the thesaurus word Is the two words “birth date” and “date of birth”.

  Then, the information consistency determination unit 20 determines the consistency of each information after calculating the degree of duplication (step S4 in FIG. 3).

  In this way, for example, even when each information includes words expressed in different expressions while having the same meaning, the degree of overlap can be accurately obtained.

  As described above, in the above-described embodiment, the information consistency determination unit 20 performs each information between information included in a search result of one information search service and information included in a search result of another information search service. Is calculated based on the number of words associated with the same semantic class in the thesaurus, for example, each word includes words expressed in different expressions while having the same meaning. Even when the information is present, the degree of overlap can be accurately obtained, and the accuracy of determining consistency between pieces of information can be improved.

  In addition, the said embodiment is only a specific example of this invention, and this invention is not limited only to the said embodiment. For example, the present invention installs a program for realizing the functions shown in the configuration diagram of FIG. 2 or a program having the procedure shown in the flow of FIG. 3 through a recording medium or a communication line in a known computer. This is also possible.
