Description

Convergent information and label retrieval method

The present invention relates to an information retrieval method.

The purpose of information retrieval is to provide users with answers to questions quickly and accurately. One of the traditional information retrieval methods is to provide multiple pieces of first information that match the first keyword and a combination of popular keywords corresponding to each of the first information after the user filters the first keyword, and use the popular key Combination of words, search again to get new results. And constantly through different keyword combinations, get different first information, and then get answers from the first information. Therefore, it is impossible to perform a second screening based on the results of the first information currently obtained.

Other information retrieval methods provide the user with multiple pieces of first information, and at the same time, in a specific area of the screen, it further prompts the user which second keywords in the first information can be used for the user to further filter the current first information. . However, these second keywords themselves will only be mixed and displayed collectively in a specific area of the screen. When the user reviews the second keywords located in the specific area, he cannot clearly know which first information the specific second keyword is related to. In other words, when users review the first information one by one, they will not know which second keywords the first information itself is related to. The problem that arises in this way is that when the user is interested in a piece of first information and hopes to further find out the information related to the piece of first information from the first information that has been found so far, the user can only use Among the second keywords displayed in a certain place on the screen, guess which one or several second keywords the first information may be related to.

In view of this, the applicant proposes an information retrieval method. According to some embodiments, an information retrieval method is applied to a database, the database includes a plurality of information and a plurality of index tags, each of the information is associated with at least one of the index tags, and the information retrieval method includes: receiving a retrieval information; Determine the index label associated with the search information, and the associated index label is a first filter label; among the information in the database, a plurality of first information associated with the first filter label is retrieved, the The first information constitutes a first information set; a plurality of first index labels corresponding to each of the first information among the index labels is retrieved, and the first index labels constitute a first index label set; and a first index label set is defined. A set of sub-index tags, the first sub-index tag set does not include the first filter tag; the first information is displayed; the first sub-index tag sets are displayed, and the display field of each first sub-index tag set Adjacent to or located in the display field or display page of the first information corresponding to the first sub-index tag set; receiving a second filter tag, the second filter tag being selected from any of the first sub-index tag set A first index label; and a plurality of second information related to the second screening label among the first information of the first information set, and the second information constitutes a second information set.

In summary, according to some embodiments, the first sub-index tag set is displayed for each piece of first information in a scattered manner on or near each piece of first information, and the respective first information is only displayed The first set of sub-index tags associated with this first information is displayed to the user. The user can perform further filtering for a certain first index tag in a certain first information of interest.

The information retrieval method is applicable to a database1. According to some embodiments, the information retrieval method is executed on a server, and the server can read the data of the database 1 from the memory. According to some embodiments, the server receives the input of the retrieval information 2 through a peripheral control interface, such as a keyboard or a mouse. According to some embodiments, the server receives input of retrieval information 2 via the network. The database 1 contains a plurality of information 101. The information 101 can be, but is not limited to, text or pictures. Please refer to FIG. 1, which is a schematic diagram of a database according to some embodiments. As an example, the database 1 includes a plurality of information 101 such as Info 1, Info 2 to Info 7 and so on.

After receiving the search information 2 sent by the user, the information search method determines the index tag 102 related to the search information 2 and defines it as the first screening tag 3. The retrieval information 2 can be, but is not limited to, text or pictures. The index tag 102 can be, but is not limited to, text or pictures and other materials. According to some embodiments, the retrieval information 2 is exactly the same as the index tag 102. According to some embodiments, the search information 2 and the index tag 102 are different but related. Relevance can be established through, but not limited to, the meaning of the information, the frequency of information co-occurrence, or user preference surveys. According to some embodiments, the user selects at least one retrieval information 2 from the preset retrieval information 2 list, and the information retrieval method receives the selected retrieval information 2 and determines the index tag 102 associated with the sentence. According to some embodiments, the user enters the retrieval information 2 of the sentence, and the information retrieval method determines the index tag 102 associated with the sentence through an algorithm. The first screening tag 3 is an index tag 102 associated with the search information 2 and used to screen the information 101 in the database 1. Please refer to Figure 2 and Figure 3 together. FIG. 2 is a schematic diagram of a search page according to some embodiments; FIG. 3 is an information relationship diagram of a database according to some embodiments. For example, after the user enters the search information 2 of the keyword D in the search field 10, the information search method determines the index label 102 related to the search information 2, that is, the D of the index label 102 shown in FIG. It is defined as the first screening label 3.

Each piece of information 101 in the database 1 is associated with at least one index tag 102. Please refer to FIG. 3, for example, Info 1 of information 101 is associated with A, B, and C of index tag 102. The information retrieval method retrieves multiple pieces of information 101 in the database 1 that are associated with the first screening tag 3. The pieces of information 101 retrieved by the information retrieval method are all the first information 41, and the pieces of first information 41 collectively constitute a first information set 4. Please refer to FIG. 3 and FIG. 4 together. FIG. 4 is a schematic diagram of the first information set according to some embodiments. For example, D of the first screening label 3 corresponds to Info 2, Info 3, and Info 5 of information 101. The information retrieval method retrieves information 101 such as Info 2, Info 3, and Info 5, all of which are the first information 41 and collectively constitute the first information set 4.

The information retrieval method retrieves a plurality of index tags 102 corresponding to each first information 41 among the index tags 102. The index tags 102 are all the first index tags 511, and the first index tags 511 together constitute a first index tag set. The information retrieval method defines a first sub-index tag set 51, and the first sub-index tag set 51 does not include the first screening tag 3. 3, Info 2 of the first information 41 in the foregoing example corresponds to B and D of the index label 102; Info 3 of the first information 41 corresponds to A, B, C, and D of the index label 102; and the first information 41 The Info 5 corresponds to B, C, D of the index label 102. Therefore, for Info 2 of the first information 41, B and D of the index label 102 are both the corresponding first index label 511, and B and D together form a first index label set. The D of the first index label 511 is the first screening label 3, that is, the index label 102 used to filter out the first information 41. Therefore, the D of the first index label 511 must be the common index label 102 of all the first information 41. In other words, D of the first index label 511 is not helpful for further filtering the first information 41. Therefore, the information retrieval method definition does not include the first sub-index tag set 51 of the first screening tag 3. For example, the first index tag set of Info 5 of the first information 41 is B, C, D, and the first sub index tag set 51 is B, C. According to some embodiments, the information retrieval method only retrieves the index tags 102 that are associated with each first information 41 and are not the first screening tags 3 to obtain the first sub-index tag set 51. According to some embodiments, after the information retrieval method retrieves the index tags 102 associated with each first information 41, the first screening tags 3 are eliminated to obtain the first sub-index tag set 51.

The information retrieval method displays the first information 41, and the information retrieval method displays the first sub-index label sets 51. According to some embodiments, "display" may be sending a display command that requires the display to display. According to some embodiments, the display command may be a control command inside the server, and the display command requires a display connected to the server through the control interface to display. According to some embodiments, the display command may be a control command sent by the server, and the display command requires the display of the client connected to the server via the network to display. According to some embodiments, the display command may include information such as display content and display fields. The displayed content may be, but is not limited to, the first information 41 or the first sub-index label set 51. The display field can be, but is not limited to, the field coordinates displayed on the display or the paging page 13. Please refer to FIG. 5. FIG. 5 is a schematic diagram of a search result page according to some embodiments. For example, the information retrieval method displays first information 41 such as Info 2, Info 3, and Info 5 on a search result page, and displays the first sub-index label set 51 corresponding to each first information 41, respectively. The displayed content can include, but is not limited to, all or part of the text or pictures of the first information 41 or the first sub-index tag set 51.

Please refer to Figure 6. Figure 6 is a schematic diagram of the search result page of some conventional technologies. The conventional technology displays a plurality of first information 41 and index tags 102 associated with the first information 41. The index tags 102 are generated by counting the contents of all the first information 41, so the corresponding relationship between the index tags 102 and each first information 41 is not clear. In addition, these index tags 102 constitute a total index tag collection 15 in the set. The total set of index tags 15 is displayed in a specific area of the screen, so that the user has no way of knowing the relevance of the index tags 102 and the first information 41. For example, the A of the index label 102 stands for "Peas shoes". For users who are familiar with the appearance of various shoes, they can easily select "Peas shoes" from Info 2, Info 3 and Info 5 of First Info 41. However, for users who do not have relevant background knowledge, when they particularly like Info 3 shoes and want to find similar shoes, they cannot be sure whether the Info 3 shoes are the total set of index tags. 15 "Peas shoes" referred to in the middle. 5, according to some embodiments, the display field of the first sub-index tag set 51 is adjacent to the display field of the first information 41 corresponding to the first sub-index tag set 51. Therefore, in the foregoing example, the user can clearly know that the "Peas shoes" of A of the index label 102 corresponds to the shoes of Info 3 of the first information 41. According to some embodiments, the first index label 511 indicates the characteristics of the first information 41. For example, C of the index label 102 represents "no strap", and prompts users who are following Info 5 about the features they may prefer.

The information retrieval method receives the second screening label 7. The second screening tag 7 is selected from any first index tag 511 in the first sub index tag set 51. In the foregoing example, the user is interested in the A feature of Info 3 of the first information 41, and therefore selects A of the first index label 511. The A of the first index label 511 is the second screening label 7. According to some embodiments, the information retrieval method sends a display command that causes the display of the receiving end to display a first index label 511 that can be clicked. When any one of the first index tags 511 is clicked, the aforementioned receiving end generates and sends a one-point selection signal. After receiving the click signal, the information retrieval method generates the second screening label 7 according to the first index label 511 that is clicked. According to some embodiments, the “clicking” can be a selection of the first index label 511 through a mouse, a stylus, a finger, or any pointing method. For example, please refer to FIG. 5, using the mouse to control the cursor 11 to select the first index label 511.

The information retrieval method retrieves a plurality of first information 41 of the first information set 4 that is associated with a plurality of first information 41 of the second screening tag 7. The first information 41 retrieved by the information retrieval method is all the second information 81, and the second information 81 collectively constitutes the second information set 8. Please refer to FIGS. 7 and 8 together. FIG. 7 is an information relationship diagram of a first information set according to some embodiments; FIG. 8 is a schematic diagram of a second information set according to some embodiments. For example, in Info 2, Info 3, and Info 5 of the first information set 4, A of the second screening label 7 only corresponds to Info 3. The information retrieval method retrieves Info 3 of the first information 41, and defines Info 3 as the second information 81. Info 3 itself constitutes the second information set 8.

Please refer to FIG. 9 and FIG. 10 together. FIG. 9 is an information relationship diagram of a database of some conventional technologies; FIG. 10 is a schematic diagram of search results of some conventional technologies. After receiving the second screening tag 7 in the conventional technology, the second screening tag 7 is retrieved in the entire database 1. For example, the A of the second screening label 7 corresponds to Info 1, Info 3, Info 4, Info 6 and Info 7 of the information 101 within the range of the database 1. The information 101 may not be related to the first information 41 obtained by using the first screening tag 3, and the user has no way of knowing which of the information 101 is related to the first information 41. Therefore, for the user, the second screening tag 7 does not provide a more convergent search result 16 within the range of the first information set 4. Instead, the second screening label 7 provides a group of search results 16 that is different from the first screening label 3, making the results of the search process divergent and unable to converge.

Please refer to FIG. 11 and FIG. 12 together. FIG. 11 is the information relationship diagram of some other conventional technology databases; FIG. 12 is a schematic diagram of the retrieval results of other conventional technologies. After receiving the second screening tag 7, some other conventional techniques re-search the intersection of the first screening tag 3 and the second screening tag 7 in the entire database 1. This method can obtain a more limited search result 16 within the range of the first information set 4. However, this method must perform the search and comparison within the entire database 1, which is time-consuming and occupies the amount of system computing. For example, please refer to FIG. 7 and FIG. 11 together. Similarly, the retrieval result 16 of Info 3 is obtained. The embodiment of FIG. 7 consumes 3 comparison steps of the first information 41, while the prior art of FIG. 11 consumes 7 comparison steps of the information 101.

According to some embodiments, the information retrieval method performs retrieval within the scope of the first information set 4 after receiving the second screening tag 7 instead of within the scope of the entire database 1. According to some embodiments, after the information retrieval method retrieves the second information set 8 associated with the second screening tag 7 within the range of the first information set 4, the information retrieval method provides the user to associate with the second information sets 8 The second sub-index label collection. The user selects from the second sub-index tag set to obtain the third screening tag. Thereafter, the information retrieval method retrieves the third information set associated with the third screening tag within the scope of the second information set 8. By continuously repeating the same process, the information retrieval method limits the original search scope from database 1 to the first information set, the second information set, the third information set, the fourth information set, etc., until the user stops the search or Until all the information in the data set can no longer be distinguished by the index tag 102.

According to some embodiments, the first index label 511 may be, but is not limited to, text or pictures. According to some embodiments, the second index label or the index label derived from the repeated information retrieval method may also be, but not limited to, data such as text or pictures.

Please refer to FIG. 13, which is a schematic diagram of the collection relationship of search result pages according to some embodiments. For example, the A of the first index label 511 can be "Doug Shoes", the B of the first index label 511 can be "Flat bottom", and the C of the first index label 511 can be "No straps". Therefore, based on the corresponding relationship between Info 3 of the first information 41 and A of the first index label 511, the user can understand that the appearance of "Doug Shoes" looks like the shoes shown in the picture information of Info 3, and Info 2 and Info 5 do not have the characteristics of "Doug Shoes". Similarly, based on the correspondence between Info 3 of the first information 41 and C of the first index label 511, and the correspondence between Info 5 of the first information 41 and C of the first index label 511, the user can understand Info 3 And Info 5 has the feature of "no strap", and it can be inferred that Info 2 should have the feature of "band".

For example, A of the first index label 511 may be a screenshot of the toe part of Info 3 of the first information 41. Therefore, when the user prefers the toe cap feature of Info 3, but cannot describe the feature in words, the user can easily select the first information 41 by the corresponding relationship between Info 3 of the first information 41 and A of the first index label 511. An index label 511 A for further search.

For example, A of the first index label 511 can provide both the keyword "Doug Shoes" and a screenshot of the toe part of Info 3 of the first information 41. Therefore, the user can understand that the shoes with the characteristics of the toe part of Info 3 are "Peas shoes".

According to some embodiments, in the step of displaying the first sub-index label set 51 of the information retrieval method, only the first index label 511 corresponding to at least two first information 41 is displayed. For example, referring to FIG. 13, the A of the first index label 511 only corresponds to the Info 3 of the first information 41, so the A of the first index label 511 is not displayed. Because the features recorded in A of the first index label 511 can only be used to distinguish one piece of first information 41, namely Info 3. According to some embodiments, in the step of displaying the first sub-index label set 51 of the information retrieval method, the first index label 511 corresponding to all the first information 41 in the first information set 4 is not displayed. For example, referring to FIG. 13, the B of the first index label 511 corresponds to all the first information 41, so the B of the first index label 511 is not displayed. Because the features recorded in B of the first index label 511 cannot be used to further filter the first information set 4.

Referring to FIG. 13, according to some embodiments, the information retrieval method displays an information number of 9. The information number 9 is adjacent to the first index label 511. The number of information 9 is the number of first information 41 with the same first index label 511 in the first information set 4. According to some embodiments, the information number 9 provides a basis for the user to select the first index label 511 as the second screening label 7. For example, when the user wants to quickly obtain a convergent search result, selecting the first index label 511 corresponding to a larger number of information 9 does not help achieve the goal. Because the first index tag 511 is used as the second screening tag 7, the same number of second information 81 as the number of information 9 will be obtained. According to some embodiments, the information retrieval method determines whether to display the first index label 511 according to the size of the information number 9 corresponding to the first index label 511. For example, the first index label 511 corresponding to a larger number of 9 information, that is, the first index label 511 with poor filtering ability, is not displayed.

Referring to FIG. 13, according to some embodiments, the search result page displayed by the information retrieval method may include a first information set 4 and a first sub-index tag total set 5. The first information set 4 includes a plurality of first information 41; the first sub-index tag total set 5 includes a plurality of first sub-index tag sets 51; the first sub-index tag set 51 includes at least one first index tag 511. Each of the first information 41 corresponds to a first sub-index tag set 51 and constitutes a plurality of first information combined tag sets 6. In contrast to the prior art only providing the first sub-index tag collection 5 in a specific area of the search result page, according to some embodiments, the information retrieval method provides multiple first information and tag collections 6, so that the user can learn the first information The association between 41 and the first sub-index tag set 51. According to some embodiments, please refer to the display field 14 of the first sub-tab set in FIG. 13 that is adjacent to or located in the display field or display page of the first information 41 corresponding to the first sub-tab set 51, so that the user It is easy to recognize that the first information 41 is related to the first sub-index tag set 51 corresponding to it.

According to some embodiments, the display field 14 of the first sub-index tag set is adjacent to the display field of the first information 41 corresponding to the first sub-index tag set 51. According to some embodiments, "adjacent" may refer to the distance between the specific first information 41 and the display field 14 of the corresponding first sub-index label set, which is smaller than the distance between the first information 41 and other first sub-index label sets. Display the distance between fields 14. The "distance" may be, but is not limited to, the shortest distance, the longest distance, or the geometric center point distance. Please refer to FIG. 13, for example, the shortest distance between Info 2 of the first information 41 and its corresponding first sub-index label set 51 (only including B of the first index label 511) is smaller than Info of the first information 41 2 and the shortest distance between the other first sub-index label set 51 (including A, B, C of the first index label 511); it is also smaller than the first information 41 of Info 2 and the other first sub-index label set 51 (only Contains the shortest distance between B and C) of the first index label 511.

According to some embodiments, the display field can be, but not limited to, using wireframes, color blocks, fixed blanks, etc., to separate the contained information content from the surroundings. Please refer to FIG. 14A. FIG. 14A is a schematic diagram of the display fields of the first sub-index label set according to the first embodiment. For example, the blank distance between Info 2 of the first information 41 and its corresponding first sub-index label set 51 (only including B of the first index label 511) is the same as that of Info 3 of the first information 41 and its corresponding The blank distances between the first sub-index label set 51 (including A, B, and C of the first index label 511) are the same. The regularity is generated by means of fixed blanking, so that the user can recognize the relevance between the first information 41 and the corresponding first sub-index label set 51. According to some embodiments, the display field may be the field itself or an extension of the field containing the information content. According to some embodiments, the "extension" may be, but is not limited to, using connecting lines, field borders, field color blocks, etc., to extend a field adjacent to another field. Please refer to FIG. 14B. FIG. 14B is a schematic diagram of the display fields of the first sub-index label set according to the second embodiment. For example, the display fields of the first sub-index label set 51 (including A, B, and C of the first index label 511) are extended to the side of Info 3 of the corresponding first information 41 by using the field border. Therefore, the shortest distance between the field border of the display field of the first sub-index label set 51 (including A, B, C of the first index label 511) and the corresponding Info 3 of the first information 41 is less than the first The shortest distance between the field border of the display field of the sub-index label set 51 (including the A, B, and C of the first index label 511) and the other first information 41.

According to some embodiments, “nearby” may mean that for a specific first information 41, in addition to displaying the corresponding first sub-index label set 51, other first sub-index label sets 51 are not displayed at the same time. Since only the specific first information 41 and its corresponding first sub-index label set 51 exist at the same time, the distance between the two is the shortest and unique. For example, according to some embodiments, after the display field of the first information 41 is selected, the display field 14 of the first sub-index tag set corresponding to the first information 41 is displayed. Please refer to FIG. 14C. FIG. 14C is a schematic diagram of the display fields of the first sub-index tag set according to the third embodiment. In the third embodiment, the user moves the cursor 11 to the first information 41, that is, the display field 14 of the first sub-index label set corresponding to it is displayed. Since only the first information 41 and its corresponding first sub-index label set 51 are displayed, there are no other first sub-index label sets 51 and the first information 41 that are less than the distance between the first information 41 and the first information 41. The distance between the corresponding first sub-index label set 51. According to some embodiments, the "select" may be a click on the first index label 511. According to some embodiments, the “selection” may be moving the cursor 11 to the display field of the first information 41.

According to some embodiments, the display field 14 of the first sub-index tag set is located in the display field of the first information 41 corresponding to the first sub-index tag set 51. Please refer to FIG. 14D. FIG. 14D is a schematic diagram of the display column of the first sub-index label set according to the fourth embodiment. For example, the first sub-index label set 51 (including A, B, C of the first index label 511) corresponding to Info3 of the first information 41 is displayed in the field of the display field of Info3 of the first information 41 Within the border.

According to some embodiments, the display field 14 of the first sub-index tag set is located in the display page of the first information 41 corresponding to the first sub-index tag set 51. Please refer to FIG. 14E and FIG. 14F together. FIG. 14E is a schematic diagram of selecting the first information according to some embodiments; FIG. 14F is a schematic diagram of displaying the paging of the first sub-index tag set according to some embodiments. For example, if the user clicks on Info 3 of the first information 41 with the cursor 11, or moves the cursor 11 to Info 3 of the first information 41, the display page of the first information 41 is displayed (FIG. 14F). Wherein, the display field 14 of the first sub-index label set corresponding to Info 3 of the first information 41 is located in the display tab.

According to some embodiments, the information retrieval method further includes receiving window information before the step of retrieving the index tag 102. According to some embodiments, when the information retrieval method receives the window information, it can learn the first information 41 currently displayed on the client according to the window information. The "window information" can be, but is not limited to, the scroll 12 position or the paging page 13 of the web page. For example, please refer to FIG. 15A, which is a schematic diagram of a scroll display window according to some embodiments. According to some embodiments, the client sends the coordinates of the reel 12 to the server, so that the information retrieval method running on the server learns the first information 41 such as Info 2, Info 3, and Info 5 currently displayed on the client. For example, please refer to FIG. 15B, which is a schematic diagram of a page display window according to some embodiments. According to some embodiments, the client sends the page number 131 of the page 13 to the server, so that the information retrieval method running on the server knows that the current page displayed on the client includes Info 2, Info 3, Info 5, etc. A page of information 41. According to some embodiments, the information retrieval method retrieves the first index label 511 corresponding to the first information 41 displayed on the client after receiving the window information. Therefore, it is avoided that the user feels the delay of the system operation in the operation.

To generate the second information 81, the information retrieval method uses the first screening tag 3 to filter the first information set 4 from the database 1, and then selects the second information set 8 from the first information set 4. Therefore, the second information set 8 corresponds to the first screening label 3 and the second screening label 7 which are filtered out. Please refer to FIG. 16, which is a schematic diagram of a search result page according to other embodiments. According to some embodiments, the information retrieval method displays the first screening label 3 and the second screening label 7 corresponding to the second information 81. Through this, the user knows the common features of all the second information 81 of the second information set 8. According to some embodiments, the information retrieval method displays the first screening tag 3, the second screening tag 7, and the third screening tag corresponding to the third information.

According to some embodiments, the display order of the plurality of first index tags 511 of the first sub-index tag set 51 may be determined by conditions such as click rate, information release time, information relevance, or a combination of the foregoing conditions.
