Description

  The present invention relates to an information search apparatus, an information search method, and a program.

  As a conventional method for searching for information, for example, Patent Document 1 discloses a configuration in which input data at the time of information search is replaced with a conversion table and an actual search is performed.

  In Patent Document 2, a keyword in registration information is converted by conversion information stored in advance, the converted keyword is added to registration information and registered, and an input keyword is converted again by conversion information at the time of search. A configuration is disclosed in which registration information corresponding to a converted keyword is obtained.

  Patent Document 3 discloses a technique for generating a search condition that searches for a character string that is equal to a search key except for a unit symbol notation method or a numerical element.

  However, in the techniques of Patent Document 1 and Patent Document 2, the rules for how to convert given input data are not always clear, and the search efficiency is improved by using the data of the conversion results. The grounds are not clear.

  The technique of Patent Document 3 is effective only for numerical search, and is not applicable to search for other information.

An example of information retrieval is retrieval of model names of electronic components. The name of the electronic component is not always fixed. For example, for the same electronic component, the packaging form may be different for each department that handles the same, and the model name may be changed correspondingly. In such a case, when identifying electronic components between departments, it is necessary to retrieve the model name in the counterpart department. In that case, it may be difficult to search in the counterpart department depending on how the model name is transformed.

  SUMMARY OF THE INVENTION In view of the above problems, the present invention is directed to causing an information retrieval apparatus, an information retrieval method, and a computer to execute an information retrieval apparatus that can effectively improve retrieval efficiency in accordance with the relationship between predetermined information to be retrieved and a retrieval key. The purpose is to provide a program.

  In the present invention, a search key pattern having a configuration that can be hit from the search key is created according to the relationship between the predetermined information and the corresponding search key, and the predetermined information is hit based on the search key pattern. Create an adaptive search key with possible configurations.

  As described above, according to the present invention, a search key pattern having a configuration that can be hit from the search key is created according to a predetermined relationship between the predetermined information and the search key corresponding to the predetermined information. A key pattern can be obtained. Furthermore, since the adaptive search key having a configuration capable of hitting the predetermined information is created based on the search key pattern, the predetermined information can be obtained with certainty.

  For this reason, according to the present invention, for example, when there is a difference in some characters between a character string as predetermined information to be searched and a character string as a search key, the search key pattern Create a wild card ("?") That does not identify different characters. As a result, the search key pattern can be surely hit by the search key.

  In addition, when the number of character digits of the predetermined information to be searched is different from the search key pattern, an adaptive search key is created to cope with this. The adaptive search key obtained in this way makes it possible to reliably hit corresponding predetermined information.

  As described above, according to the present invention, when searching for predetermined information, a search key pattern that can be surely hit from the search key is obtained, and further, the predetermined information can be surely hit from the search key pattern. By obtaining a search key, it is possible to obtain a correct search result easily and reliably.

  When searching for a model name of an electronic component as described above (hereinafter also referred to as “model name verification”), a human has conventionally created a search key based on experience. However, when there are a large number of search targets such as hundreds of points, the search key creation work becomes enormous, and improvement in efficiency has been desired.

  For example, a model name of an electronic component generally includes a symbol representing a packing form. In the design department parts list (referred to as “BOM” (Bill of Materials)), this “packing form” symbol is not included or is generally described with a temporary symbol that has no meaning. Since the packaging format of electronic parts (“rose goods” or “taping goods”) depends on the purchase quantity (required number) of electronic parts, this symbol has an important meaning in the parts list for manufacturing departments for purchase arrangements. This is because it has no meaning on the design department parts list.

  For this reason, for example, in the design department component list, the symbol “separate product” is displayed as the “packing form” symbol in the model name of each electronic component. As a result, as shown in FIG. 4, the model names do not match between the design department parts list and the manufacturing department parts list. 4 is “ABCS3F470JG” in the parts list for the design department, but “ABCT3F470JG” in the parts list for the manufacturing department, and the symbols in the fourth digit are “S” and “T”. Is different.

  Further, as another example, as shown in the third item of FIG. 4, there is a mismatch in the model name between the design department part list and the manufacturing department part list depending on the presence or absence of the actual product seal. That is, the type name of the resistor in the third item of FIG. 4 is “XYZ3GEJ102J” in the design department parts list, but “XYZ3GEJ102JU” in the manufacturing department parts list, and the seventh digit “Y” in the latter is The former is omitted, and the “U” at the end is omitted.

  For this reason, in the case of model name verification using the model name on the manufacturing department part list as a search key to obtain the corresponding model name on the design department part list, the first digit of the capacitor shown in FIG. In the case of the capacitor in the second term, it is necessary to ignore the last digit and search.

  In the case of the resistor of item 3 in FIG. 4, in order to make the model name on the design department part list hit with the model name on the manufacturing department part list, the 7th digit from the top in the manufacturing department part list It is necessary to delete the “Y” in the search and ignore the “U” at the end.

  Unless such pre-processing is performed, the model name between departmental parts lists will not be hit, and a collation result will not be obtained even though it is essentially the same part.

  The embodiment of the present invention has a configuration that solves the above problems.

  FIG. 1 shows a functional block diagram of a model matching system according to an embodiment of the present invention, and FIG. 2 shows a schematic processing flow thereof.

  As shown in FIG. 1, the information processing apparatus refers to a search key input unit 10 for inputting a search key, an input key storage unit 20 for storing an input search key, and an adaptive key table 40 to input the above search. An adaptive key generation unit 30 that generates a predetermined adaptive search key based on the key, an adaptive key storage unit 50 that stores the generated adaptive search key, and a component model name DB 70 based on the adaptive search key The part model name search unit 60 that searches for a corresponding part model name and the part model name storage unit 80 that stores the part model name obtained by the search.

  Next, the operation of the model name collating system will be described with reference to FIG.

  First, in step S1, in the case of the relationship between a predetermined search key and predetermined information, that is, in the case of the above model name collation, the model name on the manufacturing department part list and the corresponding design department part list A key pattern that can be hit by the former is created according to the relationship with the model name. For example, in the case of the example in FIG. 4 described above, a key pattern as shown in the “character string type” data in FIG. 6 is created.

  That is, for the capacitor of the first term (No. 1), the fourth digit is a wild card (“?”), And for the capacitor of the second term (No. 2), the last digit is a wild card (“?”). In the case of the resistor in the third term (No. 3), the seventh digit and the end are used as wild cards. As a result, when the model name on the parts list for the manufacturing department is used as the search key, the corresponding key pattern (“character string type”) can be surely hit. The key pattern created in this way is registered on the memory belonging to the adaptive key generation unit 30. The above processing may be performed manually by the operator, or a corresponding program is created and executed by the CPU 1 of the computer shown in FIG. 3, so that the key is based on predetermined information corresponding to the search key. It is also possible to configure to automatically create a pattern.

  Next, the adaptive key table 40 is created in step S2. Here, based on the key pattern created in step S1, an adaptive search key having a configuration in which the predetermined information to be searched can be surely hit is created. For example, in the case of the example in FIG. 4 described above, an adaptive search key is created as shown in the “search character string” data in FIG.

  That is, in the case of the capacitor of the first term (No. 1), an adaptive search key “search character string” having the same configuration as the key pattern “character string type” is obtained. Similarly, in the case of the capacitor of the second term (No. 2), an adaptive search key “search character string” having the same configuration as the key pattern “character string type” is obtained.

  On the other hand, in the case of the resistor of the third term (No. 3), the model name on the design section parts list corresponding to the key pattern “character string type” (the third term in FIG. 4) Accordingly, the seventh-digit wild card “?” Is deleted, and the number of digits is reduced to obtain an adaptive search key “search string”. With such a configuration, it is possible to reliably hit the corresponding model name on the design department part list shown in FIG.

  The adaptive search key created in this way is stored in the adaptive key table 40 in association with the corresponding key pattern as shown in FIG.

  The above processing may be performed manually by the operator, or a corresponding program is created and executed by the CPU 1 of the computer shown in FIG. 3, so that key patterns and predetermined information to be searched (that is, for the design department) It is also possible to configure such that it is automatically created based on the relationship with the model name on the parts list.

  The above is the preparation stage process. Next, the process at the stage of actual search (namely, model name matching process) will be described.

  In step S 3, when the operator inputs a search key at the search key input unit 10, this is stored in the input key storage unit 20. Based on this input search key, the adaptive key generation unit 30 refers to the adaptive key table 40 to obtain a corresponding adaptive search key.

  Specifically, for example, when the model name “XYZ3GEYJ102JU” on the part list for the manufacturing department of the resistor in the third item of FIG. 4 is input as a search key, the adaptive key table 40 as shown in FIG. Then, “Type 3” “XYZ3GE? J102J?” Is hit. This is because all the digits other than the wild card “?” Match each other.

  Next, the adaptive key generation unit 30 obtains “XYZ3GEJ102J?” As an adaptive search key “search character string” corresponding to the hit “type 3” (step S4). That is, as described above, a character string having a configuration in which the seventh-digit wild card “?” In “XYZ3GE? J102J?” As the “character string type” is deleted is obtained. This is stored in the adaptive key storage 50.

  In step S5, the part form name search unit 60 searches the part form name DB 70 using the adaptive search key “XYZ3GEJ102J?” Obtained here. As a result, “XYZ3GEJ102J” is obtained as the model name on the corresponding design department part list. This is because all the digits other than the wild card “?” Match each other.

  As described above, according to the embodiment of the present invention, the key pattern that can be surely hit with the search key (in this case, “model name on the parts list for manufacturing department”) and the predetermined information ( In the case of this example, an adaptive search key that can reliably hit “model name on the design department part list”) is created. Then, they are stored as an adaptive key table 40 in association with each other. As a result, by referring to the adaptive key table 40, it is possible to reliably obtain predetermined information corresponding to the search key.

  On the other hand, for example, assume a configuration in which only the key pattern “character string type” is present and no adaptive search key “search character string” exists. When the model name “XYZ3GEYJ102JU” on the part list for the manufacturing department of the resistor in the third item in FIG. 4 is input as a search key as in the above example, “XYZ3GE? J102J?” Is hit as the corresponding key pattern. It is possible to make it. However, even if the part model name DB 70 is searched using this key pattern as a search key, the model name “XYZ3GEJ102J” on the corresponding design department part list cannot be obtained. When the two are compared, the eighth digit character is “J” in the key pattern and “1” in the model name on the corresponding design department part list, which is different from each other.

  Similarly, assume a configuration in which only the adaptive search key “search character string” and no key pattern “character string type” exist. When the model name “XYZ3GEJ102JU” on the part list for the manufacturing department of the resistor in the third item in FIG. 4 is input as a search key as in the above example, “XYZ3GEJ102J?” Is selected as the corresponding adaptive search key. It cannot be hit. When the two are compared, the seventh digit character is “Y” in the search key and “J” in the adaptive search key, which is different from each other.

  FIG. 3 is a diagram for explaining an example in which the above-described model name collation system is implemented by a computer together with FIG.

  In the figure, the computer includes a CPU 1 that performs arithmetic processing, an input unit 2 such as a keyboard for an operator to input information, a display unit 3 such as a display that provides display output to the operator, and a work area for the operation of the CPU 1. It includes a memory 4 to be provided, a hard disk drive 5 and a CD-ROM drive 6 for storing information, and a modem 7 enabling communication with an external server or the like via a communication network 8 such as the Internet.

  In FIG. 1, the adaptive key generation unit 30 and the part type name search unit 60 are realized by the CPU 1 executing a predetermined program, the search key input unit 10 corresponds to the input unit 2, and the input key storage unit 20. , The adaptive key table 40, the adaptive key storage unit 50, the part model name DB 70, and the part model name storage unit 80 are realized by the hard disk drive 5.

  The program is stored in the CD-ROM 6a or provided from an external server via the communication network 8, stored in the hard disk drive 5, installed, loaded into the memory 4, and executed by the CPU 1. . As a result, the operation described above with reference to FIG. 2 is executed, thereby realizing the model name collation system according to the embodiment of the present invention.

  Details of the operation in the information search method according to the embodiment of the present invention will be described with reference to FIG.

  The processing flow of FIG. 5 includes a step S11 for registering “character string type” (key pattern), a step S12 for inputting data as a search key (hereinafter referred to as “search key character string”), and a search key. Step S13 for storing the character string Steps S14 to S17 for automatically extracting the corresponding "character string type" by comparing the stored search key character string with a plurality of registered "character string types" , Step S18 of automatically generating a search character string ("Search character string": "Adaptive search key") from the extracted "character string type" Step S18, storing the automatically generated search character string Step S19, Step S20 for obtaining a search result using a search character string as a search condition, Step S20 for storing the search result (hereinafter referred to as “search result character string”), Step S21 for inputting the search key Steps S22 and S23 for executing steps S15 to S21 for all character strings, step S24 for automatically displaying (or printing) a list of search key character strings, search character strings, and search result character strings. Become.

  Hereinafter, an actual processing example will be described.

  Here, it is assumed that the data of type 1 to type 3 (see FIG. 6) are registered in advance as the plurality of “character string type” data.

  These “character string type” data have the following contents. In general, the name of the electronic component that is the basis of these character string types is given by the component manufacturer (see FIGS. 9 to 11).

  That is, in the type 1, the first to third digits are fixed to English letters “ABC”, the fourth digit is fixed to free (wild card), and the fifth to eleventh digits are fixed to alphanumeric characters “3F470JG”. That is, the “character string type” data of type 1 is “ABC? 3F470JG”.

  Next, in type 2, the first to thirteenth digits are fixed to alphanumeric characters “C1234JB1H104K”, and the fourteenth digit is free (wild card). That is, the “character string type” data in this case is “C1234JB1H104K?”.

  In Type 3, the first to sixth digits are fixed to alphanumeric characters “XYZ3GE”, the eighth to twelfth digits are also fixed to alphanumeric characters “J102J”, and the seventh and thirteenth digits are free (wild card). Is done. That is, the “character string type” data is “XYZ3GE? J102J?”.

  In this example, the model name on the parts list for the manufacturing department is applied as a search key character example in step S12. Specifically, the model name collation is performed using the following four model name data A) to D) as a search key character string. It shall be input to the system. Then, it is an object to obtain whether or not the corresponding model names are included in the design department parts list, and if so, whether or not the model name is deformed and its contents.

Examples of the search key character string are as follows.
A) ABCT3F470JG
B) GRN9876B11H102KA01K
C) C1234JB1H104KT
D) XYZ3GEYJ102JU
As a processing procedure, first, in the search key character string input / storing stage of steps S12 and S13, the data “XYZ3GEYJ102JU” of “ABCT3F470JG” to D) of the search key character string A) are sequentially input / saved.

  Next, the first search key character string data “ABCT3F470JG” is loaded (step S14), and the character string data “ABC? 3F470JG” of “type 1” is used as the first “character string type” in step S15. Load it.

  Next, in step S16, the search key character string data “ABCT3F470JG” of A) and the “character string type” (type 1) data “ABC? 3F470JG” are collated (step S16). In this case, it can be determined that they match (Yes), and the process proceeds to step S18.

  In step S18, the search character string data “ABC? 3F470JG” is automatically extracted, and in step S19, the search character string data is stored. Then, in step S20, search result (search result character string) data obtained by "ABCS3F470JG" is obtained, and in step S21, the search result character string data is stored.

  After that, through steps S22 and S23, the next search key character string B) “GRN9876B11H102KA01K” data is loaded, and thereafter, the same procedure as in the case of A) is executed.

  Here, the “character string type” data matching the search key character string B) “GRN9876B11H102KA01K” is not registered. Accordingly, the data of “search character string” and “search result character string” as outputs for B) are output as blanks (see FIG. 8).

  In this manner, the processing for each search key character string is executed, and as a result, a result list as shown in FIG. 8 is output.

  Next, processing for the search key character string D) will be described. That is, an example of collation (collation between search key character string “XYZ3GEYJ102JU” data and type 3 “XYZ3GE? J102J?” Data) and search character string “XYZ3GEJ102J?” Data in step S18 will be described.

  In the collation in step S16, it is first determined whether or not there is equivalent data of “character string type” registered in advance for the search key character string “XYZ3GEYJ102JU” data. If there is corresponding “character string type” data as a result of the determination (that is, when No. 3 in FIG. 6 is hit), the adaptive key table 40 is referred to by the method as described above. "Searching character string" data (in this case, "XYZ3GEJ102J?") Is extracted (step S18).

  As a modification, an automatic generation method of “search character string” data as shown in FIG. 7 is also possible.

  This method utilizes the characteristics of the model name notation of electronic parts. That is, as shown in FIGS. 9 to 11, there are arbitrary alphanumeric data indicating the function, characteristic value, and constant value of the part in a plurality of digits of the model name (product number). The lowercase x and y parts in FIG. 7 correspond to this.

  In the method according to this modification, the “search key character string” data is collated with the “character string type” data in FIG. 7 (step S15). If there is a hit, in step S18, a part of the “character string type” data and a part of the “search key character string” data are merged to automatically generate the “search character string” data shown in FIG. .

  According to this modification, the data amount of the adaptive key table 40 can be effectively reduced as compared with the embodiment shown in FIG. 6, and the maintenance processing amount of the table can be reduced.

  In the example of FIG. 5, the character string data for search is extracted or automatically generated one by one in the procedure after step S15. On the other hand, it is also possible to adopt a configuration in which a plurality of “search key character string” data and “search character string” data are collectively extracted or automatically generated, and then the search is collectively performed. .

  The example in which the present invention is applied to the name comparison of electronic parts has been described above, but the field of application of the present invention is not limited to this.

  For example, as shown below, by registering a “character string type”, application to general fuzzy search is also possible.

  For example, in a phone number search, a specific phone number is automatically generated as a search character string (adaptive search key) regardless of the presence or absence of “hyphen” in the middle of the phone number, and information search is performed using this. It becomes possible.

  Specific examples are shown below.

Free dial example:
“Character string type” (key pattern) data: 0120-222699
"Search key character string" (search key) data example: 0120-222-699 or 0120-22-2699
Further, as an embodiment of the information search apparatus of the present invention, it is possible to adopt a configuration having the functions listed below.

  1.
