A description is given of a writing fluctuation glossary creating apparatus according to an embodiment of the present invention.
FIG. 1 shows a schematic configuration of a writing fluctuation glossary creating apparatus 1.
As shown in FIG. 1, the expression fluctuation glossary creating device 1 includes an input receiving unit 3, a expression fluctuation glossary creating unit 5, and a expression fluctuation glossary storage unit 7. In this embodiment, the term fluctuation vocabulary creation apparatus 1 mounted on the client terminal used by the user, which creates the term fluctuation glossary based on the search query inputted by the user However, the present invention is not limited to this, and the writing fluctuation glossary creation device of the present invention may be a device that is mounted on a server device and that creates a writing fluctuation glossary based on a keyword such as a facility name. . In the case of the writing fluctuation glossary preparing device mounted on the server device, the operator of the input receiving unit described later is the keyword such as the facility name stored in the search database provided inside the server device or outside the server device. The input of the keyword to select is received, or the automatic input of arbitrary keywords is received.

  The input receiving unit 3 receives an input of a search query by the user. The said search query is compound words, such as a word and a phrase which a user inputs at the time of a search, and makes a request and a query to search databases, such as search conditions, a character string. The character strings include kanji characters, hiragana characters, katakana characters, alphabets, numbers, symbols and the like, and one or a combination of two or more of them may be mentioned. The said character string can receive the input by each touching the character key allocated to each character on a display screen, or by using input parts, such as a keyboard.

The expression fluctuation glossary preparing unit 5 generates an expression fluctuation glossary relating to the search query. The writing fluctuation glossary creating unit 5 includes a first creating unit 501 and a second creating unit 502.
The first creating unit 501 creates a first writing fluctuation glossary based on the search query. That is, the first creating unit 501 creates a first transcription fluctuation glossary consisting of a first transcription fluctuation term obtained by processing the search query input and accepted by the input acceptance unit 3 according to a first rule. . There is no particular limitation on the first rule used when creating the first transcription fluctuation glossary, but for example, morphological analysis, kanji-katakana conversion, katakana-kanji conversion, katakana-alphabet conversion, or alphabet-katakana conversion, etc. The following method can be used. For example, in the case of the search query "Swan Garden", according to morphological analysis, it is decomposed into units of a morpheme "Swan" and a morpheme "Garden", and the first expression swing term becomes "Swan, Garden". In this case, the first transcription swing glossary is composed of a first transcription swing term "swan, garden". On the other hand, according to the kanji-katakana conversion, the search query "Swan Garden" is converted to katakana like "Shiratori Teien", "Shirotori Teien", and "Hawcho Teien". In this case, the first writing fluctuation glossary is composed of the first writing fluctuation terms "Silatri Teien", "Shirotori Teien", and "Hakucho Teien". The first transcription fluctuation glossary created is stored in the first storage unit 701 in association with the search query.

  The second creating unit 502 creates a second transcription fluctuation glossary based on the first transcription fluctuation glossary. That is, the second creating unit 502 processes the first glossary of glossary terms created by the first creating unit 501 according to a second rule different from the first rule. Create a second transcription glossary of terms. The second rule used in the preparation of the second expression fluctuation glossary is not particularly limited, and the morphological analysis, the kanji-katakana conversion, the katakana-kanji conversion, the katakana-alphabet conversion, or the like as the first rule. A technique such as alphabet-katakana conversion can be used. For example, if the first writing swing term that constitutes the first writing swing glossary created using morphological analysis as the first rule is “swan, garden”, the second creating unit 502 As a rule of kanji-katakana conversion, katakana conversion is carried out like "Shiratori, Tyeng", "Shirotori, Tyeng", or "swab, Tyeng". In this case, the second writing fluctuation glossary is composed of the second writing fluctuation terms "Shiratori, Tayeng", "Shirotori, Tayeng", and "Purchine, Tayeng". The generated second transcription fluctuation glossary is stored in the second storage unit 702 in association with the search query and / or the first transcription fluctuation term.

The writing fluctuation glossary storage unit 7 stores the first writing fluctuation glossary created by the first creating unit 501, the first storing unit 701, and the second writing unit 502 creates the second writing unit. And a second storage unit 702 for storing the expression fluctuation glossary.
Although the above-mentioned writing fluctuation glossary compilation device 1 is provided with two creation parts of the 1st creation section 501 and the 2nd creation section 502 inside the writing fluctuation glossary compilation section 5, being limited to this Alternatively, the number of creation units may be more than two. In this case, each creation unit may use a rule different from the rule used by the other creation units, or may use a rule different from the rule used by the immediately preceding creation unit. In addition, storage units in the writing fluctuation glossary storage unit 7 are provided corresponding to the number of creation units.

An example of the operation of the device 1 shown in FIG. 1 will be described using FIG. In this example, the expression fluctuation glossary preparing device 1 generates an expression fluctuation glossary relating to a search query “Swan Garden”.
First, in step 1, the input reception unit 3 receives an input of the search query "Swan Garden".
In step 3, the first preparation unit 501 uses the morphological analysis of the search query “swan garden” which receives the input in step 1 into two units of the first morpheme “swan” and the second morpheme “garden”. "Swan, garden" obtained by disassembling was taken as the first term swing term, and the first term swing glossary composed of the first term swing term "swan, garden" was created and created The first transcript fluctuation glossary is associated with the search query “Swan Garden” and stored in the first storage unit 701.

  In step 5, the second creating unit 502 uses the first writing fluctuation term “swan, garden” included in the first writing fluctuation glossary created in step 3 to perform the second writing using the Kanji-Katakana conversion. Create a second writing fluctuation glossary consisting of shaking terms "Silatori, Tayen", "Shirotori, Tayeng", "Wow butterfly, Tayeng", and search the second writing fluctuation glossary created query "Swan Garden And the second storage unit 702. The second expression swing term includes “Shiratori”, “Shirotori”, and “Purchase” obtained by katakana converting the first morpheme “Swan” in the first expression swing term “Swan, Garden”, and the second morpheme Each is composed by combining "garden" with "Thaien" converted from katakana.

  By executing steps 1 to 5, the expression fluctuation glossary creation device 1 sets the first expression fluctuation glossary "Swan, garden", the second as the expression fluctuation glossary corresponding to the search query "Swan garden". Create a glossary consisting of the expression fluctuation glossary "Shiratori, Tyeng", "Shirotori, Tyeng", and "Purchine, Tyeng". The search query "Swan Garden" is stored in a facility database as a search database when input of the search query "Swan Garden" is accepted at the client terminal by creating such a expression fluctuation vocabulary. Among the facilities, search not only facilities "Swan Garden" that includes the keyword "Swan Garden" in its facility information but also facilities that include the keywords "Swan" and "garden", for example, the facility "Swan Japanese Garden" Is possible. The facility database may be mounted on a mobile terminal device or the like provided with a writing fluctuation glossary creation device, or may be mounted on a server device capable of communicating with the mobile terminal device.

As another example, the case where the writing fluctuation glossary creating device includes more than two creating units will be described. In this example, the expression fluctuation glossary creation device generates an expression fluctuation glossary relating to the search query “Shirotori Garden”.
First, in step 21, as in step 1, the input receiving unit receives an input of the search query “Shiratori garden”.
In step 23, as in step 3, the first preparation unit morphologically analyzes the search query “Shiratori garden” which has received the input in step 21, and uses the first expression fluctuation term “Shiratori, garden”. Create a first transcription fluctuation glossary to be constructed and store in a first storage unit.

In step 25, as in step 5, the second creating unit converts the first writing fluctuation term “Shiratori, garden” included in the first writing fluctuation glossary created in step 23 into kanji-katakana conversion. Then, a second glossary of glossary consisting of a second expression of fluctuation term "Shiratori, Tyeng" is created and stored in a second storage unit.
In step 27, the third creating unit (not shown) converts the second writing fluctuation term “Shiratori, Tien” included in the second writing fluctuation glossary created in step 25 into katakana-kanji, Create a third transcription swing glossary composed of the third transcription swing terms "swan, garden" and store it in the third storage unit.

In step 29, the fourth preparation unit (not shown) performs the Kanji-Katakana conversion of the third notation fluctuation term "swan, garden" included in the third notation fluctuation glossary created in step 27. A fourth writing fluctuation glossary composed of the fourth writing fluctuation terms "Shiratori, Tyeng", "Shirotori, Tyeng", and "Purchine, Tyeng" is created and stored in the fourth storage section.
By performing steps 21 to 29, the expression fluctuation glossary creation apparatus is configured to generate the first expression fluctuation glossary "Sirari, garden" as the expression fluctuation glossary corresponding to the search query "Sirtori Garden", 2nd Nomenclature fluctuation glossary "Shiratori, Teien", third notation fluctuation glossary "Swan, garden", fourth notation fluctuation glossary "Shiratori, Teien", "Shirotori, Teien", "War Swan, Teien" Create a glossary. Among the facilities stored in the facility database when the client terminal receives an input of the search query "Shirotori Garden" by creating such a expression fluctuation vocabulary for the search query "Shirotori Garden" Not only facilities that include the keyword "Shiratori Gardens" in their facility information, but also facilities that include the keywords "Swan" and "garden" based on the third expression Shake Glossary "Swan, Gardens", for example, facilities " Search for the Swan Garden, or search for the facility "Shirotori Garden (Yoromi) Shirotori Teien", which includes the keywords "Shirotori" and "Tien" in its information based on the fourth expression fluctuation glossary "Shirotori, Teien" It becomes possible.

  The display order determination unit 535 may further reflect the difference in the number of constituent units described above in the display order. For example, among a plurality of facilities for which the display order is to be determined, the display order is determined such that facilities having the same number of structural units as the search query are displayed at the top for facilities having the same score. Can. As another example, it is possible to separately provide a reference score based on the difference in the number of constituent units, and to consider the reference score when giving the first score. For example, a positive score (for example, score "5") is given as a reference score when the number of constituent units is the same, or a negative score (for example, a reference score when the number of constituent units is different) , A score "-5") can be given. In the former case, for example, for the search query "Victory Tsuru-mai" consisting of two components "Victory" and "Tsuru-mai", the first server-side expression fluctuation term "Victory, cafe, Tsuru-mai" has a component While the second server-side expression "Victory, Tsuru-mai" has three components and is the same number, the second server-side expression "Victory, Tsuru-mai" has a reference score of "5". In this case, with respect to the score "2" of the facility "Victory Cafe Tsurumai" to which the first server side notation swing term "Victory, cafe, Tsurumai" relates, the second server side notation swing term "Victory, Tsurumai" Because the reference score "5" is added to the facility "Victory Tsurumai" related to the total score "6", the display order determination unit 535 places the facility "Victory Tsurumai" having a large value of the total score into the facility "Victory Cafe Tsurumai" Display higher.

An example of the operation of the search system 500 shown in FIG. 7 will be described using FIG.
First, in step 51, the input reception unit 13 provided in the client terminal 510 receives an input regarding a search query of a search user. In this example, it is assumed that the input of the search query “victory tsurumai” is accepted.
In step 53, the first client-side creating unit 1501 in the client-side writing fluctuation glossary creating unit 15 morpheme-analyzes the search query “victory tsurumai” based on the input reception in step 51, and the first client side A first client-side transcription fluctuation glossary composed of the transcription fluctuation terms “victory, tsuru-mai” is created and stored in the first client-side transcription fluctuation glossary storage unit 1701.

In step 55, the second client-side creating unit 1502 in the client-side writing fluctuation glossary creating unit 15 generates the first client-side writing fluctuation based on the first client-side writing fluctuation glossary created in step 53. The term "victory, tsurumai" is converted to the kanji-katakana conversion and katakana notation fluctuation, and the second client-side expression fluctuation term "victory, thulmai", "victory, thulmai", "victory, thulma", "victory, thulma" The second client-side writing fluctuation glossary composed of “Victory, Kakumai,...” Is created and stored in the second client-side writing fluctuation glossary storage unit 1702.
In step 57, the search request unit 19 performs the search query, the first writing fluctuation glossary in step 53, and the second writing fluctuation term in step 55 to request a search for a facility corresponding to the search query in step 51. The collection is transmitted to the server device 530 via the client communication unit 20.

  In step 61, the first server-side creation unit 1051 in the server-side notation swing glossary creation unit 105 performs morphological analysis of the facility name of the facility stored in the facility database 103, and performs the first server-side notation. A first server-side transcription wobble glossary composed of fluctuation terms is created and stored in the first server-side transcription fluctuation glossary storage unit 1071. In this example, as shown in FIG. 4, a first server-side expression swing glossary "Victory, Tsurumai" is created for the facility "Victory Tsurumai", and a first server-side representation swing glossary for the facility "Victory Cafe Tsurumai" "Victory, cafe, Tsurumai" is created.

  In step 63, the second server-side creating unit 1052 in the server-side notation swing glossary creation unit 105 converts the first server-side notation swing glossary created in step 61 into kanji-katakana conversion and katakana notation. Fluctuation conversion is performed to create a second server-side transcription fluctuation term, and the second server-side transcription fluctuation glossary storage unit 1072 is stored. In this example, as shown in FIG. 4, the second server-side expression swing glossary "Victory, Tsurumai", "Victory, Tsurumai", "Victory, Tsuruma", "Victory, Tsuruma", "Victory," for the facility "Victory Tsurumai" , Kakumai "..." is created, the second server-side writing shaking glossary "Victory, cafe, Tsurumai", "Victory, cafe, Tsurumai", "Victory, cafe, Tsuruma", about the facility "Victory Cafe Tsurumai", "Victory, Cafe, Tsuruma", "Victory, Cafe, Kakumai" ... are created.

  In step 65, the server device 530 receives the search request transmitted in step 57 via the server communication unit 111. The first client-side transcription fluctuation glossary received is stored in the first client-side storage unit 1131 in the client-side transcription fluctuation glossary storage unit 113, and the second client-side transcription fluctuation glossary is the second Is stored in the client-side storage unit 1132 of the

In step 67, the first extraction unit 115 refers to the first server-side writing fluctuation glossary created in step 61, and the first client-side notation stored in the first client-side storage unit 1131. Extracts swaying terms that match swaying terms. In this example, the first server-side writing term "Victory, cafe, Tsurumai" including both of the component units "Victory" and "Tsurumi" of the first client-side writing term "Victory, Tsuru-mai" is the facility "Victory. It is extracted in association with the cafe Tsurumai.
In step 69, the second extraction unit 116 refers to the second server-side writing fluctuation glossary created in step 63, and the second client-side notation stored in the second client-side storage unit 1132 Extracts swaying terms that match swaying terms. In this example, in the case of "Victory, Tsurumai" of the second client-side writing fluctuation terms, the second server-side writing fluctuation terms "Victory, Tsurumai", which includes both of the constitutional units "Victory" and "Tsurmai", and " Victory, cafe and Tsurumai are extracted in association with facilities "Victory Tsurumai" and "Victory Cafe Tsurumai", respectively.

  In step 71, the first score giving unit 117 gives a score to the first server-side writing fluctuation term in step 67 and the second server-side writing fluctuation term in step 69, and the first score storage unit 119 Store. In step 71, the first score gives the first server-side writing swing term extracted in step 67 a higher score than the second server-side writing swing term extracted in step 69. For example, a score "2" can be given to the first server-side writing fluctuation term, and a score "1" can be given to the second server-side writing fluctuation term. In this example, a score "2" is given to the first server-side expression swing term of the facility "Victory Cafe Tsurumai", a score "1" is given to the second server-side expression swing term, and the first of the facility "Victory Tsurumai" A score of "1" is given to the server side expression fluctuation term of 2.

  In step 73, the display order determination unit 535 determines the display order of the facilities associated with each server-side handwritten swing term based on the score given in step 71. The determination of the display order is determined to be the upper display order in descending order of score. For example, when a plurality of server-side expression swing terms are given a score for one facility, their total score may be used as an indicator for determining display order, or a plurality of server-side expression swings for one facility. The highest score among the scores assigned to the terms may be used as an indicator for determining the display order. In the former case, for example, the score of the facility "Victory Cafe Tsurumai" is given as "2" for the first server-side expression, and "1" for the second server-side expression. The score is "3". Since the score of the facility "Victory Tsurumai" is assigned "1" for the second server-side handwritten swing term, its total score is "1". Therefore, the facility "Victory Cafe Tsurumai" with a higher total score is ranked higher than the facility "Victory Tsurumai". In the latter case, for example, the highest score among the scores given to the server-side handwritten swing terms of the facility "Victory Cafe Tsurumai" is "2", and is assigned to the server-side handwritten swing terms of the facility "Victory Tsurumai" Since the highest score among the scores is “1”, the facility “Victory Cafe Tsurumai” with a higher score is ranked higher than the institution “Victory Tsurumai”.

In step 75, along with the display order determined in step 73, the facility associated with the server-side handwritten swing term extracted in step 67 and step 69 is transmitted as a search result to the client terminal.
At step 59, the client terminal 510 receives the information on the search result at step 75 and outputs it via the output unit 513. In this example, the display unit as the output unit displays the facility "Victory Cafe Tsurumai" in the first rank and the facility "Victory Tsurumai" in the second rank as search results.
