JPH09259142A - Device for place name retrieval with roman letter/ japanese syllabary notation - Google Patents

Abstract

PROBLEM TO BE SOLVED: To make it possible to obtain correct Roman letter notation of the name of a place where a moving body is moving by limiting the retrieval range of each data base according to position information on the moving body, and regarding only place names included in a limited retrieval range as objects of retrieval and converting the inputted Roman letter/KANA(Japanese syllabary) notation of a place name into correct Roman letter/KANA notation. SOLUTION: A retrieval processing part 10 limits the retrieval ranges of a hierarchical plane name information data base 14, a homonymous different- notation data base 16, and a synonymous identical-notation data base 18. Namely, the retrieval ranges are narrowed down for retrieval and conversion to obtain a place name in correct Roman letter notation. Further, the external synonymous identical-notation data base 18 of the homonymous different-notation data base 16 is provided, so even if a pilot mispronounces a place name, it is converted into the place name in correct Roman letter notation and a flight position can be specified, so that the flight position of the aircraft can be displayed by illumination at a correct position on a map 12 according to the place name in correct Roman letter notation.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a place name retrieving device for a Roman name / kana notation for converting various Roman / kana notations of an inputted place name into a positive Roman / kana notation and uniquely specifying the same. The present invention relates to a place name search device used when a place name is searched based on a report from a mobile body.

[0002]

2. Description of the Related Art A pilot operating a moving body such as an aircraft flies an aircraft within a specified air space according to a flight plan prepared in advance. However, the flight information providing system of the aircraft is based on the place name reported by the pilot. The actual current position of the aircraft is displayed on the bulletin map installed in the control department. A procedure for displaying the current position of the aircraft on this bulletin map will be described.

When the air traffic controller operating the flight information providing system hears the place name of the current position where the aircraft is flying by communicating with the pilot, it inputs the place name in Roman characters from the keyboard of the flight information providing system. Since each place name is assigned to each position on the bulletin map, by inputting the place name, the place corresponding to the place name on the bulletin map is lit up and displayed. In this way, the current flight position of the aircraft is recognized. As a result, the ATC officer provides the pilot with weather information about the location, information about the airfield, information about the flight area, and the like.

By the way, the place name is not limited to the place name in Roman characters that is uniquely determined as "KAMAKURA" such as "Kamakura", but also "KOFU" and "K" such as "Kofu".
There are some place names that may be written in different Roman letters such as “OHU”, “KOUFU”, “KOHFU”, etc. Therefore, different placeholders may input different Roman letters. For example, in the case of "Kofu", data with different homophones such as "KOFU" and "KOHFU" may be registered in advance, and the desired place name in Roman alphabet can be entered even if the person inputs various Roman alphabets. By converting, it is possible to uniquely identify the place name in Roman letters. Therefore, if the pilot reports "Koufu" by voice, even if the controller enters "KOFU", "KOHU", etc., it will be converted to the correct Roman alphabet and the search will be performed. The position of "Kofu" can be displayed in a lighted state.

[0005]

However, it is unclear whether or not a place name for which data with different homophones need to be prepared, for example, a place name including a long sound such as "Ofuna" or a dumb sound such as "Honda" is read. There are a lot of place names, etc., and it takes a lot of time to search a database in which all of them are registered.

[0006] In addition, there are different place names with different readings depending on the place. For example, change "Koyama" to "KOYAM"
Some call it "A" and some call it "OYAMA." Therefore, the romanization of positive letters varies depending on where you are flying. The pilot must be sure to call the name of the place you are flying. You may not know it, so you might report "Koyama" as "Koyama" while flying over Tochigi Prefecture. At this time, if the pilot reports "Koyama" to the pilot, he or she will usually say "OYAM".
You will enter "KOYAMA" exactly as it is reported, not "A." Then you will see a different location ("K
OYAMA ") is lit up, or it is not possible to display the moving place of the aircraft which is the moving body because there is no place name.

The present invention has been made to solve the above problems, and an object of the present invention is to provide a place name search device capable of correctly obtaining a positive Roman character notation of a place name where a moving body is moving. To provide.

[0008]

In order to achieve the above-mentioned object, the place name search device from the Roman character / Kana notation according to the present invention provides the place name information such as the prefecture / town / village name of the positive Roman character / Kana notation. Place name information database to store,
Different homonyms and romanizations for a place name with a positive romaji / kana notation. A homonym notation database, a search range limiting means for limiting the search range of each of the databases based on the position information of the moving body, and only a place name included in the limited search range as a search target,
It is characterized by having a place name conversion means for converting the Roman character / kana notation of the input place name into a Roman character / kana notation in which it is positive.

The place name information database hierarchically stores place name information such as prefecture / city / town / village names in positive Roman letters / kana notation, and the search range limiting means is for moving the moving body. The present invention is characterized in that the current moving position of the moving body is estimated based on the plan, and the estimated moving position is used as position information.

The map display means for displaying a map and the range designation means for designating a range on the map display means are provided, and the search range limiting means searches the range designated by the map display means. It is characterized by being a range.

Further, when a plurality of place names are searched as conversion candidates, the place name conversion means compares the estimated current position of the moving body with the position information of the searched place name to uniquely identify the place name in Roman characters / kana. It is characterized by specifying.

BEST MODE FOR CARRYING OUT THE INVENTION Preferred embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a block diagram of a flight information providing system using a place name search device for Roman / Kana notation according to the present invention. This system is a display 2 as a map display means for displaying input characters and maps.
A keyboard 4 for inputting a place name, a mouse 6, a magnetic disk 8 as an external storage unit for storing various databases, and a search processing unit 10 for controlling and processing the entire apparatus.
And a bulletin map 12 for displaying the current flight position of an aircraft or the like. The magnetic disk 8 has a hierarchical place name information database (DB) 14 that hierarchically stores place name information such as prefecture names of cities, towns, villages, etc. written in positive Roman letters, and the same Romanization notation for the place names written in positive Roman letters. Homophone database (DB) 16 for registering, Homophone database (DB) 18 for registering Romanized notation for a place name in positive Roman alphabet, and flight plan memory for storing flight plans And a section 20 are stored. Of course, it is not necessary to store all the data on one magnetic disk 8, and a different external storage device may be separately provided.

The hierarchical place name information database 14 in the present embodiment is a database for domestic use in Japan, and is a place name dictionary which stores municipalities for each prefecture as a hierarchical structure as shown in FIG. The name of each place is written in Roman letters, and is a place name dictionary with this as the correct name. In addition, the latitude and longitude are added to each place name as position information for specifying the position of each place name. FIG. 2 shows only the prefectures, towns and villages names, but also includes map information that can specify flight locations such as mountain ranges, river names, and buildings. In the homophone different notation database 16, as shown in FIG. 3, various Roman alphabets that are possible for a certain place name are registered in association with positive Roman alphabets. Also, by adding the latitude and longitude to each place name and registering, each place name is uniquely associated with each place name in the hierarchical place name information database 14. As shown in FIG. 4, various romanizations that may be pronounced when reading a kanji of a certain place name are registered in the all-phonetic transcription database 18 in association with positive romanizations. . Also, by adding the latitude and longitude to each place name and registering, each place name is uniquely associated with each place name in the hierarchical place name information database 14.

The search processing unit 10 is a search range limiting means for limiting the search range of each of the databases 14, 16 and 18 based on the position information of the aircraft. It is a place name conversion means for converting into a notation.

The characteristic feature of the present embodiment is that, first of all, when obtaining a place name written in Roman characters that is positive, the search range of each of the databases 14, 16 and 18 is narrowed down to some extent and then searched and converted. That's what I did. As a result, the search processing time can be significantly reduced. In the present embodiment, the search range is specified to some extent from the current flight position of the aircraft or the assumed flight position. Second, the homophones and different notation database 16
Not only the same sound notation database 18 is provided, but even if the pilot mistakenly pronounces a place name (kanji), it can be converted into a correct place name written in Roman letters to specify the flight position. In particular, place names with the same kanji character are usually not within the same range, so if you limit your search to some extent,
It can be converted into the Roman alphabet of the place name of the correct reading for the place.

Next, the operation of this embodiment will be described with reference to the flowchart shown in FIG.

First, in the case of the present embodiment, it is premised that a flight according to a flight plan is carried out in advance,
The flight plan is stored in the flight plan storage unit 20. Flight plans include departure airports, transit points,
It includes aircraft stop plans, location reporting locations, arrival airports, and other aircraft movement plans, and records location information that can identify the flight location of the aircraft at each time. The flight path of the aircraft is specified from these pieces of information, and the approximate flight position at the current time is estimated (step 101). If there is a difference between the flight plan and the actual flight route according to the report from the pilot, the controller communication officer corrects the current flight position (step 102). The flight position is expressed in latitude and longitude. And the search processing unit 1
Although 0 limits the search range based on the flight position, in the present embodiment, the prefecture above which flight is being performed is analyzed based on the latitude and longitude of the flight position, and the prefecture is hierarchically structured. The place name information database 14 is searched (step 103). When flying at a flight position, for example, on a prefectural border, one or more adjacent prefectures may be searched. It is difficult to express each prefecture precisely with latitude and longitude because it is a region with a range, but in the present embodiment, it is only divided into prefectures as a unit for narrowing down the search range. There is no need to pursue the accuracy of.
In that sense, the latitude and longitude position information shown in FIG. 2 also shows only one set of longitude and latitude information, and how to set the range of each prefecture is merely a design matter. In the case of a small area such as a town or village, the location of the government office may be specified.

Here, when the place name is reported by the pilot, the reported place name is entered from the keyboard 4 in Roman letters. The search processing unit 10 searches the hierarchical place name information database 14 by the inputted place name in Roman letters (step 104). This search is performed only for the place names belonging to one to several prefectures which are the search targets as described above. As a result of the search, if the prefecture has the same place name with the same Roman character notation, the Roman name notation of the place name is determined as the Roman character notation that the input is positive (Step 10).
5).

As a result of the search, if there is no place name that is the same as the inputted Roman character notation, the place name in Roman character notation that is positive is uniquely specified as follows. First, only the limited search range of the homophone different notation database 16, that is, only the place name in the prefecture in flight is searched. The prefecture to which each data of the homophone different notation database 16 belongs can be specified by the information of longitude and latitude. Alternatively, a code may be provided for each prefecture so that they can be identified. If there is no corresponding place name, then the same allotment database 18
Search only the place names in the limited search range of. In this way, when the correct place name in Roman letters can be uniquely specified, the hierarchical place name information database 14 is searched again (step 104).

Further, as a result of the search, when a plurality of data are retrieved from the input Roman alphabet, the plurality of search target prefectures are limited to those in flight, or the radius from the current flight position is changed. The search range is further narrowed down by providing limiting conditions such as within Km or within a rectangular area centered on the current flight position (step 106). And again,
The search range of the hierarchical place name information database 14 is limited (step 103).

As described above, even when the same place name in the Roman alphabet is not obtained, the above process (step 106,
107), the hierarchical place name information database 1
As a result of searching for 4, it is possible to uniquely identify the place name in positive Roman letters. When the place name in the Roman alphabet is obtained, the bulletin board map 12 associated with the place name is displayed.
The upper position is lit up and displayed.

As described above, according to the present embodiment, even if the controller communication officer inputs the place name reported by the pilot in the Roman character notation when inputting it from the keyboard 4, this is not positive. A positive Roman alphabet can be obtained from the Roman alphabet and can be uniquely specified. Also, even if the pilot does not report the correct place name, it can be converted into a place name in Roman alphabet that is positive. As a result, the flight position of the aircraft can be lit and displayed at the correct position on the bulletin board map 12 based on the place name in positive Roman letters obtained by the above process.

Further, since the conversion process into the positive Roman alphabet is performed after narrowing down the search range to some extent, the search processing time can be greatly shortened. Further, by narrowing down the search range in this manner, for example, a place name in which "Koyama" is expressed as "KOYAMA" and a place name in which "OYAMA" is positive can be correctly discriminated. .

In the above description, the flight position of the aircraft is estimated while the flight position is corrected based on the report from the pilot based on the flight plan. However, the position of the aircraft previously confirmed and the movement from the pilot are confirmed. The flight position of the aircraft can also be estimated by reporting position estimation information such as direction and speed.

In addition, the present embodiment is characterized in that the place name information database is narrowed down to some extent based on the flight position and the place names included therein are searched, so that in the above description, The search range is set to each prefecture, and the municipality names are set in the lower layer to form hierarchical place name information, but it is not limited to this.
It is also possible to set only the place name included in a radius of several kilometers centered on the flight position estimated based on the latitude and longitude data as a search target.

If the data contained in the databases 14, 16 and 18 can be associated with each other, the information on the latitude and longitude is not always necessary. The capacity can be increased.

Further, in the above-described embodiment, the example of the search by inputting the Roman characters has been described, but the system can be similarly used in the case of inputting kana. That is,
"Oyama" and "Koyama" are also used for kana input
It can be easily assumed that the following is entered, or "Ofuna" is entered as "Ofuuna", "Ofuuna", etc.
This is because a similar problem occurs. Therefore, even in the case of inputting kana, it is possible to search by the same configuration and method as above. Throughout the specification, the expression "romaji / kana notation" means "romaji" or "kana".
However, it does not deny the use of both.

Embodiment 2 In the above embodiment, the flight position of the aircraft is estimated from the movement plan and the search range is limited based on the estimated flight position.
The present embodiment is characterized in that the search range can be designated for the input person. That is, a map is displayed on the display 2 and the range specified on the display 2 is displayed on the display 2 by using the mouse 6.
The search range can be 6,18. The range designating means for designating the range may be designated by inputting from the keyboard 4 instead of the mouse 6.

Embodiment 3. Step 10 shown in FIG.
In step 7, if there are multiple conversion candidates as a result of the search,
In the first embodiment, the search range is designated again, but the estimated current position of the aircraft is compared with the position information of the retrieved place name, that is, the respective latitudes and longitudes are compared, The place closest to the estimated current flight position may be regarded as the position where the flight is actually performed, and the place name may be converted into the Roman character notation that is positive.

As described above, in each of the above-described embodiments, the case where the system is used in the flight information providing system of an aircraft has been described. However, for example, it is a long-distance truck or the like that moves on the ground or moves on the sea. It can also be used in ships and the like.

Further, in each of the above-described embodiments, the information about the prefectures, cities, towns and villages over a wide area nationwide is held, but it is limited to a specific area depending on the system used, and the town name and street address are hierarchical. You may also have it.

Further, although the latitude and longitude are added as the position information of the place name, in the case of limiting to a specific area, the position may be specified by dividing into blocks in advance without using the latitude and longitude information. .

[0034]

As described above, according to the first and second aspects of the invention, when obtaining a place name written in Roman characters that is positive, the search range of each database is narrowed down to some extent and then the search is performed. It can be shortened significantly. Also, not only the homophone and homograph database but also the homophone database is provided, so even if a certain place name is entered in the wrong romanization, it is possible to convert it to the correct romanization place name. . In particular, even if the place name of the same Kanji is read differently depending on the place, even in such a case, the search range was narrowed down to some extent based on the current position of the moving body, so it was decided to use positive Roman letters. It is possible to convert correctly.

According to the third invention, since the search range is specified based on the position of the moving body estimated based on the moving plan of the moving body, it is possible to convert the place name into the correct Roman alphabet. Become.

According to the fourth invention, it is possible to make the input person search within the search range.

According to the fifth invention, since the place name which is considered to be closest to the estimated current position is converted into the Roman character notation,
It is likely to be converted to the correct Roman alphabet.
