Description

  The present invention relates to a service cooperation server, method, system, program, and recording medium.

Currently, there is a strong demand for technologies that combine existing services as technologies for developing and operating new services without delaying new business opportunities by configuring new services while reusing existing services. Yes. As a technology for combining these services, OWL-S (Web Ontology Language for) is used for input / output messages (input / output information) of web services such as Semantic Web Service and Service Composition Technology as shown in Non-Patent Document 1. Assign semantic descriptions using ontology languages such as Services). Non-Patent Document 3 uses such a service cooperation environment to determine the correspondence between ontology (semantic information) assigned to a message by using ontology mapping technology, and even a message with a different message format is included in the message. If the assigned ontology is of the same type, a method for exchanging messages between different systems is provided by converting the format.
David Martin, et al., “OWL-S: Semantic Markup for Web Services (OWL-S), [online], November 2004, OWL-S Coalition, [Heisei Searched July 12, 2006], Internet <http://www.daml.org/services/owl-s/1.1/overview/> Takemoto, 9 others, "Service composition method and implementation in service provision architecture suitable for ubiquitous computing environment", Transactions of Information Processing Society of Japan, February 2005, Vol. 46, No. 2, p. 418-433 Nakatsuji and two others, “Proposal and Evaluation of Message Mapping Method Based on Semantic Information for Flexible System Cooperation”, Database Society of Japan Letters, 2005, Vol. 4, No. 1, p. 37-40

However, in the above Non-Patent Document 1 and Non-Patent Document 2 technologies, in order to aim to link services while reusing existing services, the input / output message specifications of linked reuse source service components are For example, a common part must be included such that the reuse source services have an area search in common. Further, as shown in Non-Patent Document 3, in the conventional reusable message detection method, the ontology only considers messages of the same type as a common part. Accordingly, in any of the above-mentioned documents, since service components that can be reused are limited to services having a common part, there is a problem in that a service that does not have a common part or a cooperation between different services cannot be performed.
Specifically, “Gourmet area search” and “Movie area search”, which have a common part called area search, are linked based on area search, and presents information about restaurants and restaurants in Shibuya, for example. However, it is not possible to realize cooperation between “movie area search” and “gourmet genre search”, which are heterogeneous services that do not have a common part.
The present invention has been made in consideration of such circumstances, and its purpose is to solve the above-described problems and to assign a more abstract sensitivity concept to the ontology of the service input / output message. It is to realize the cooperation of different services based on a common sensibility concept.

  In order to achieve the above object, the service cooperation server of the present invention includes one or more user terminals and a service provider that provides one or more services (for example, the search service providing server 3-1 in the embodiment). ~ N) and different types of services having different ontologies (for example, area ontology and gourmet ontology in the embodiment) based on the sensitivity words input by the user transmitted from the user terminal Is a service cooperation server that presents to a user in cooperation with each other, and a sensitivity ontology in which a plurality of sensitivity words constituting a group and a relationship between the sensitivity words included in the group are described, and each of the sensitivity One or more input messages related to the word (eg, place name, area name, An ontology database including a name), an input message ontology describing a relationship between the sensitivity word and the input message, and service identification information of a service that is an input target of the input message; A receiving unit (for example, the communication unit 10 in the embodiment) that receives a user input sensitivity word, and searches the ontology database using the received user input sensitivity word as a key, and one or more related to the user input sensitivity word A detection unit that detects a plurality of the input messages (for example, the control unit 11, ontology selection unit 12, area selection unit 13, and genre selection unit 14 in the embodiment), and the input target of the input message detected by the detection unit The service identification information of the service is the ontology database The service identification information reading unit (for example, the search word selection unit 151 of the search control unit 15 in the embodiment) to be read corresponding to the input message and the input message detected by the detection unit correspond to the input message. The service input / output unit (for example, the search control unit 15 in the embodiment) that outputs to the service corresponding to the service identification information read by the service identification information reading unit and obtains a service result for the input message from the service. A search execution unit 152) and a transmission unit for transmitting the service result.

  Further, the service cooperation system of the present invention is configured such that one or a plurality of user terminals, a service provider that provides one or a plurality of services, and a service cooperation server are connected to each other and transmitted by the user transmitted from the user terminals. A service cooperation system for presenting to a user by coordinating different types of services with different ontologies based on the input sensitivity word, transmitting the user input sensitivity word input by the user, and obtaining from the user input sensitivity word A user terminal that receives the linked service result, a plurality of sensitivity words that form a group, and a sensitivity ontology that describes the relationship between each of the sensitivity words, and one or more related to each of the sensitivity words A plurality of input messages, a relationship between the sensitivity word and the input message, and an input target of the input message. An ontology database including an input message ontology in which service identification information of a service is described; a communication unit that receives the user input sensitivity word; and searching the ontology database using the received user input sensitivity word as a key; A detection unit that detects one or a plurality of the input messages related to the user input sensitivity word, and the service identification information of the service that is an input target of the input message detected by the detection unit from the ontology database.

Output the service A service cooperation server including a service input / output unit that obtains a service result for the input message; and a service provider that outputs a service result for the input message input from the service cooperation server. .

  Further, the service cooperation method of the present invention connects one or a plurality of user terminals, a service provider that provides one or a plurality of services, and a service cooperation server, and a user transmitted from the user terminal. A service cooperation method for presenting to a user by coordinating different types of services with different ontologies based on the input sensitivity word, wherein the receiving unit receives the user input sensitivity word input from the user. The detection unit receives a sensitivity ontology in which a plurality of sensitivity words constituting a group and a relationship between each of the sensitivity words are described, and one or more input messages related to each of the sensitivity words , The relationship between the sensitivity word and the input message, and the service identification information of the service that is the input target of the input message, Search from the ontology database comprising the input message ontology described by using the user input sensitivity word received by the receiver as a key, and detect one or a plurality of the input messages related to the user input sensitivity word; A service identification information reading unit reads out the service identification information of the service that is an input target of the input message detected by the detection unit, in correspondence with the input message from the ontology database, and a service input / output unit is configured to detect the detection Output the input message detected by the unit to the service corresponding to the service identification information read by the service identification information reading unit corresponding to the input message, obtaining a service result for the input message from the service, The transmission unit transmits the service connection. And transmitting a.

  As described above, according to the present invention, even for a service having an input / output message having completely different ontology (for example, area information and restaurant classification), the abstraction of the ontology assigned to the message is increased. By collaborating on a perception basis, it becomes possible to realize heterogeneous service-related systems. As a result, it is possible to increase the number of service components necessary for service cooperation, and to create a new service through heterogeneous service cooperation. In this way, a new service can be created by reusing and reusing existing services across the axis of sensitivity. Moreover, since this has the effect of improving the quality and quantity of the service, it has the effect of increasing the ability to attract portal services and improving sales. Furthermore, there is an effect that a service that has been rarely used up to now alone can be linked with other services to improve the frequency of use of the service.

Next, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a block diagram showing the overall configuration of a heterogeneous service cooperation system according to the present invention. In this embodiment, a search service will be described as an example of a heterogeneous service.
The service cooperation server 1 that performs the heterogeneous service cooperation of the search service providing servers 3-1 to 3 -N, the search service providing servers 3-1 to 3 -N that provide the search service, and the heterogeneous service cooperation The user terminals 2-1 to 2-M owned by the user are connected via the network 100.
The network 100 includes a public network such as a fixed telephone network, a mobile phone network, and the Internet, and a private network such as a LAN (Local Area Network) and a dedicated line.

The user terminals 2-1 to 2-M receive a sensitivity word representing an image to be searched and a target word to be searched by a user who wants to use the search service, and the center of the search range. The sensitivity word and the object word are transmitted to the service cooperation server 1 together with the central position information indicating the point. Hereinafter, the sensitivity word, the object, and the center position information are collectively described as user input information.
An example of an input screen on the user terminals 2-1 to 2-M is shown in FIG. Here, the search target object indicates a target to be searched by the user, and is, for example, an object such as a date or leisure. In the present application, as shown above, when an abstract word such as a date is input as shown above, the range of service cooperation is expanded. For example, a specific word such as a meal or even an Italian dish It may be entered.
In addition, the center position information indicating the center point of the search range is the user terminals 2-1 to 2-M when the user terminals 2-1 to 2-M transmit user input information to the service cooperation server 1. The position information of the nearest communication base station connecting to the network 100 may be used as the center position information, or the user terminals 2-1 to 2-M are provided with a GPS device having a GPS function in advance, and acquired by this GPS function. The position information of the user terminals 2-1 to 2-M may be the center position information, or the position information of the center point input by the user input may be the center position information.

Next, the configuration of the service cooperation server 1 will be described. FIG. 3 is a conceptual diagram showing the configuration and relationship between the sensitivity ontology 161 and the area ontology 162 in the ontology database 16.
In the service cooperation server 1, the ontology database 16 includes a sensitivity ontology 161 that is a dictionary in which the concepts of sensitivity words are classified. Sensitivity ontology 161 is a group composed of a plurality of sensitivity words, such as the inclusion relationship (higher / lower concept relationship or hierarchical relationship) of each sensitivity word included in the group, synonym (equivalence) relationship, similarity relationship, etc. The relationship between sensitivity words is also described. The sensitivity ontology 161 may be a dictionary created by manual classification or a dictionary created by analyzing a dictionary or a dictionary as long as the relationship between the sensitivity words is described.
In the present specification, a group is a sensitivity word group composed of a plurality of sensitivity words having an inclusive relationship (higher / lower conceptual relationship or hierarchical relationship), synonymous relationship, and similar relationship.

The ontology database 16 includes an area ontology 162, a gourmet ontology 163, a movie ontology 164, a lodging ontology 165, and a play facility ontology 166. It is a dictionary. In this specification, ontology is a description of relationships (relationships) between concepts such as equivalence, similarity, and hierarchical relationship between concepts. The concept here is a property that is characterized when a plurality of information (instances) are grouped. Specifically, for example, the concepts labeled “fashionable” are “fashionable”, “fashionable”. It is a concept that consists of multiple pieces of information. The concepts in the gourmet genre are “Chinese cuisine”, “French cuisine”, etc., and these two concepts are siblings. “Chinese cuisine” is a child concept. , And so on.
This ontology is also called an ontology system that expresses the meaning of an input message, and is a vision in the semantic web service and service composition technology, and is built along with these two technologies.

  The genre name, which is a concept in the ontology that the ontology database 16 has, is a classification name. In the area ontology 162, it is a generic name for a place name, for example, “around Ginza”. In the gourmet ontology 163, For example, in the genre names of restaurants such as “Western food”, “Chinese food”, “Pasta”, etc., in the movie ontology 164, for example, in the genre names of movies such as “love”, “action”, “mystery”, etc. , Genre names of accommodation facilities such as “ryokan”, “minshuku”, “condominium”, and amusement facility ontology 166 are genre names of amusement facilities such as “amusement park”, “game center”, “aquarium”, etc. . These genre names are input messages that are actually input as search keys to the search service providing servers 3-1 to 3 -N, and are also called input IF (interface), service IF (interface), and the like. The ontology database 16 in which these are described serves as a guideline and service specification as to what kind of cooperation service is to be created.

FIG. 4 is a conceptual diagram showing the relationship between each ontology included in the ontology database 16. In the ontology database 16, the genres stored in the area ontology 162, gourmet ontology 163, movie ontology 164, accommodation ontology 165, and play facility ontology 166 are associated with the sensitivity words of the corresponding sensitivity ontology 161 ( Are tied).
This association may be stored in the ontology database 16 in any format description. In this embodiment, as an example, a description will be given using the data format of the sensitivity ontology 161 shown in FIG. Corresponding notation words, broader terms of the broader concepts, narrower terms of the lower concepts, synonyms, synonyms, genre names stored in each ontology, and the ontology to which the genre name belongs are the sensitivity words. A case will be described in which each is described in association with each other. Note that a sensitivity word does not necessarily have a one-to-one correspondence with a corresponding written fluctuation word, broader word, lower word, synonym, synonym, and genre name. That is, there may be no word corresponding to the sensitivity word, or there may be one or more corresponding words.

These associations indicate the appearance correlation between the sensitivity word and the input message vocabulary included in the sensitivity word dictionary, such as the number of times that the sensitivity word and the input message appear simultaneously in one sentence on a diary-like site (blog). It may be automatically constructed by measuring. In addition, the correspondence may be constructed based on a questionnaire or the like that selects or describes an input message associated with the sensitivity word, or the service provider may think and construct it manually.
FIG. 6 is an example of data of the area ontology 162. The area ontology 162 includes, for each place name or area name, an upper area that includes the place name or area name, a lower area that includes the place name or area name, and a search service providing server that can search by the place name or area name. Search service identification information, which is information indicating 3-1 to 3-N, and a sensitivity word associated with the place name or area name are stored in association with each other.
FIG. 7 is an example of data on the gourmet ontology 163. For each genre name, a broader term, a narrower term, search service identification information for identifying the search service providing servers 3-1 to 3 -N that can be searched by the genre name, and a sensitivity word associated with the genre name are associated with each other. Stored.
As described above, it is assumed that the ontology database 16 stores in advance an association with a sensitivity word for each ontology with a sensitivity word as a center.

The communication unit 10 realizes communication between the user terminals 2-1 to 2-M and the search service providing servers 3-1 to 3-N via the network 100. When receiving the user input information via the communication unit 10, the control unit 11 outputs the sensitivity word and the object word to the ontology selection unit 12. The ontology selection unit 12 searches the ontology that is associated with the input sensitivity word and the object in common from the sensitivity sensitivity ontology 161 using the input sensitivity word as a key, and controls the searched ontology identification information To the unit 11. When the ontology identification information is input from the ontology selection unit 12, the control unit 11 outputs the sensitivity word and the center position information to the area selection unit 13. The area selection unit 13 searches for the place name or area name associated with the input sensitivity word in the input center position information and its lower area from the area ontology 162, and controls the searched place name or area name. To the unit 11.
Here, as the search order at this time, the input center position information and its lower area are searched first. However, for example, priority is given to the semantically close order, that is, the alias of the input center position information. The strength of the relationship with the sensitivity word is stored in the ontology database 16 in advance, and a score that combines the semantic proximity and the strength of the relationship with the sensitivity word is assigned, and the place name with the highest score is obtained. Alternatively, the area selection unit 13 may select a search target area by searching for a region name.

When the place name or the area name is input, the control unit 11 outputs the sensitivity word and the input ontology identification information to the genre selection unit 14. The genre selection unit 14 searches for the genre name associated with the sensitivity word from the ontology indicated by the input ontology identification information, and outputs the detected genre name to the control unit 11.
When the genre name is input, the control unit 11 outputs the input sensitivity word, the genre name, the place name or the region name, and the ontology identification information to be searched to the search control unit 15.
In the search control unit 15, the search word selection unit 151 has information on which search service to use among the search service providing servers 3-1 to 3 -N for each ontology in advance. FIG. 8 shows an example in which the ontology stored in the ontology database 16 and the search service providing servers 3-1 to 3 -N included in the search word selection unit 151 are recorded in association with each other.
The search word selection unit 151 reads ontology-specific search service identification information, which is a search target, corresponding to the input ontology identification information. The search word selection unit 151 reads the input genre name and the genre name-specific search service identification information associated with the genre name from the ontology corresponding to the input ontology identification information. The search word selection unit 151 compares the search service identification information by ontology with the search service identification information by genre name, and if there is a search service by ontology that is not included in the search service identification information by genre name, From the genre name that is semantically close to the genre name, the genre name associated with the ontology-specific search service identification information is searched until all the ontology-specific search service identification information corresponds to any genre name. The sensitivity ontology 161 outputs one or a plurality of pairs of the searched genre name and search service identification information corresponding to the genre name to the search execution unit 152.

When a genre name and one or more pairs of search service identification information corresponding to the genre name are input, the search execution unit 152 obtains the place name or area name input from the control unit 11 and the genre name. Output for each search service corresponding to the search service identification information, and obtain a search result from each search service.
When the number of search results falls below a predetermined minimum number, the search execution unit 152 sends a re-search command signal, a searched genre name, and identification information of the searched search service to the search word selection unit 151. Output. The search word selection unit 151 outputs the genre name for re-search to the search execution unit 152, and repeats the re-search until the number of search results exceeds the minimum number.
The search execution unit 152 outputs the obtained search result to the control unit 11, and the control unit 11 transmits the search result to the user terminals 2-1 to 2 -M via the communication unit 10.

Next, an example of the operation of the system in the configuration of FIG. 1 will be described using the flowchart of FIG. In this operation example, a case will be described in which “nice” is input as a sensitivity word as user input information, “date” is input as an object, and “Chuo-ku” is input as center position information.
Sensitivity word “nice”, object word “date” and center position information “Chuo-ku” input by the user as search requests from user terminals 2-1 to 2 -M as user input information 100 is transmitted to the service cooperation server 1 via 100. In the service cooperation server 1, the control unit 11 receives user input information via the communication unit 10 (step S1).

The control unit 11 outputs the received sensitivity word “nice” and the object word “date” to the ontology selection unit 12. When the sensitivity word and the object are input, the ontology selection unit 12 searches the sensitivity ontology 161 for a specific object associated with both the input sensitivity word “nice” and the object “date”. . The specific object is a word associated with any ontology other than the sensitivity ontology 161 stored in the ontology database 16. For example, in this operation example, both “nice” and “date” are used. It is assumed that “meal”, “movie”, and “playing facility” are searched as linked words (step S2).
The ontology selection unit 12 searches the ontology database 16 for ontology identification information associated with the word “meal”, which is one of the searched specific object words, and obtains the identification information of the gourmet ontology 163. The ontology selection unit 12 outputs the obtained specific object “meal” and ontology identification information “gourmet ontology 163” associated with the object to the control unit 11 (step S3).

When a specific object and ontology identification information are input, the control unit 11 outputs the sensitivity word “nice” and the center position information “Chuo-ku” to the area selection unit 13. The area selection unit 13 is configured such that the area selection unit 13 includes “Ginza surroundings” that are linked to the input sensitivity word “nice” in the center position information “Chuo-ku” and its lower area from the area ontology 162. ”,“ Hibiya ”, and“ Ginza ”, the closest“ Ginza area ”is detected, and the detected area name“ Ginza area ”is output to the control unit 11 (step S4).
Note that all the areas associated with the sensitivity word may be detected, or a predetermined number may be detected in order from the word most closely related to the center position information. For example, in FIG. 3, there are “Ginza neighborhood” in the order closest to “Chuo-ku”, followed by “Ginza” and “Hibiya”. In addition, in the conceptual diagram showing the relationship between the ontology in FIG. 3, the relationship between the sensitivity word and the place name or the area name is indicated by a white arrow, and the thickness of this arrow indicates the strength of each relationship. . The search order may be determined according to the strength of the relationship, or the search order may be determined by combining the strength of the relationship and the perspective of the relationship from the center position information. For example, when the relationship between the sensitivity word and the input message described above is performed, the strength of the input message is measured according to the number of times the sensitivity word and the input message appear simultaneously in one sentence. Alternatively, the strength may be determined according to the number of times the pair of the sensitivity word and the input message is linked in the questionnaire.

  When the area name “around Ginza” is input, the control unit 11 outputs the sensitivity word “nice” and the input ontology identification information “gourmet ontology 163” to the genre selection unit 14. The genre selection unit 14 searches the gourmet ontology 163 indicated by the input ontology identification information for the genre name “pasta” linked to the sensitivity word “nice”, and outputs the detected genre name to the control unit 11. (Step S5).

When the genre name is input, the control unit 11 inputs the input sensitivity word “nice”, the genre name “pasta”, the area name “Ginza neighborhood”, and the ontology identification information gourmet ontology 163 to be searched. Output to the search control unit 15.
In the search control unit 15, the search word selection unit 151 is the search service identification information classified by ontology from the previously stored information of FIG. 8, using the input ontology identification information “Gourmet Ontology 163” as a key. “3-6 to 3-10” are read out. The search word selection unit 151 is the genre name-specific search service identification information associated with the input genre name “pasta” and the genre name from the gourmet ontology 163 corresponding to the input ontology identification information. “Search service providing servers 3-6, 3-8 to 3-10” are read out. The search word selection unit 151 compares the search service identification information classified by ontology with the search service identification information classified by genre name, and detects the presence or absence of a search service classified by ontology that is not included in the search service identification information classified by genre name. In this case, as shown in FIG. 7 and FIG. 8, search service identification information “search service providing server 3-7” is detected as a search service by ontology that is not included in the search service identification information by genre name, A genre name associated with ontology-specific search service identification information is searched from “Italian”, which is a broader genre name that is semantically close to the input genre name “pasta”, and “search service providing server 3- The presence or absence of search service identification information that matches the search service identification information “7” is detected. In this way, the genre name related to the input genre name “pasta” is searched in order from the semantically close genre name until all the ontology-specific search service identification information corresponds to any genre name. . Sensitivity ontology 161 searches one or a plurality of pairs (for example, {“pasta”, “search service providing server 3-6”}) of the searched genre name and search service identification information corresponding to the genre name. It outputs to the execution part 152 (step S6).

When the genre name and one or more pairs of search service identification information corresponding to the genre name are input, the search execution unit 152 receives the area name “Ginza area” input from the control unit 11, the genre name, Is output for each search service corresponding to the search service identification information, and a search result is obtained from each search service (step S7).
The search execution unit 152 detects whether or not the number of search results is below a predetermined minimum number. If the number of search results falls below a predetermined minimum number, it is assumed that sufficient search results have not been obtained, and the search execution unit 152 tries the search term selection unit 151 to try again with another search term. A re-search command signal, a genre name already searched, and identification information of the searched search service are output. The search word selection unit 151 outputs the genre name for re-search to the search execution unit 152, and repeats the re-search until the number of search results exceeds the minimum number (step S8).

When the number of search results exceeds the predetermined minimum number, the search result is output to the control unit 11 assuming that the minimum required search result has been obtained. When the search result is input, the control unit 11 detects whether or not all the objects specified in step S2 have been searched. (Step S9)
For this detection, for example, a flag indicating that the search is started is set for the specific object for which the ontology selection is performed in step S3, and the presence or absence of a specific object for which the flag is not set is determined. Any method may be used as long as it can detect whether or not all of the objects specified in step S2 have been searched.
The control unit 11 repeats steps S3 to S10 until all the objects specified in step S2 are searched.
When the control unit 11 detects that search results for all specific objects have been obtained, the search result for each specific object is sent to the user who is the transmission source of the search request via the communication unit 10. The search result is transmitted to the terminal 2-1 (step S10).

  In step S4, the area selection unit 13 may hold a predetermined initial area granularity for each ontology, and search for a place name or a region name corresponding to the sensitivity word from the area ontology 162. The predetermined initial area granularity determines the search range for each ontology. For example, in the case of a gourmet ontology, the search is performed in the range of municipalities. In the case of a movie ontology, the range is determined by the prefecture. The area is determined by.

  In step S8, when the number of searches is less than the minimum number, the search is performed again from step S6. However, the genre may be selected again in step S5, or the area entered without changing the search word or the like. Using the name “surrounding Ginza” as a key, the area name is changed to a semantically close area, or the upper area including the input area name is searched from the area ontology 162, and the search service providing servers 3-1 to 3-3 -N may be used as an area name to be searched. These re-search conditions may be determined in advance by the service cooperation server 1 or may be selected by the user during the re-search.

  In the present embodiment, an area ontology 162, a gourmet ontology 163, a movie ontology 164, a lodging ontology 165, a game facility ontology 165, which are linked to the sensitivity ontology 161 stored in the ontology database 16 to guide search terms. However, the present invention is not limited to this. For example, in the case of online shopping, it is possible to cope with various different services by using an ontology corresponding to a service provider such as a product ontology. .

In this embodiment, the case where an abstract object is input as an object has been described as an example. However, a specific object “meal” may be input by the user, and in particular, the object Even when there is no input, it is possible to detect an object related to a sensitivity word from the sensitivity ontology 161.
Further, among a plurality of specific objects obtained by the present invention and one or a plurality of search results corresponding to the objects, for example, a predetermined number is extracted in order of search results for each object, The extracted search results that are close to each other can be linked to each other and presented to the user. As for this distance, the addresses of the search results may be read together with each search result at the time of search, and those close to the address of the search results may be presented to the user as an example plan.
At this time, it is also possible to obtain the nearest station of each search result from the address and further present the traffic route between the search results in a plan in which the search results are combined.
In addition, a plurality of specific objects and search results thereof can be displayed on a map and selected by the user. For example, as shown in FIG. 10, which is an example of a screen presented to the user terminals 2-1 to 2-M as a result of the service tie-up, the points of the search results are indicated by marks on the map in order from the top of the search results. It is also possible to indicate by changing the upper rank of the mark according to the size of the mark. Similarly, the nearest station and the optimum route can be shown at the same time. As a result, there is an effect that the user is presented with a plan based on cooperation of different services. In addition, it is possible for the user to arbitrarily change a part of the plan based on this plan without causing a heavy burden on the user.

As described above, according to the present invention, it is possible to link different services using input messages with different ontologies, which are linked with the same sensitivity concept based on sensitivity words with high abstraction. There is.
For example, as shown in FIG. 3, “Ginza” in the area ontology 162, “Pasta” in the gourmet ontology 163, and “Love” in the movie ontology 164 are associated with the sensitivity word “Nice”. Different services such as search, gourmet genre search, and movie genre search can be linked from a single sensitive word “nice”. At this time, it is possible to follow the sensitivity word “nice” from the sensitivity word related to “nice” in the sensitivity ontology. Therefore, the sensitivity word input by the user is not necessarily “nice”. Good.
In other words, based on the ambiguous search request of “nice”, area search, gourmet genre search and movie genre search are performed. As a result, for example, a cooperative service plan such as “eating pasta in Ginza and watching romance movies” Can be presented.
Therefore, it is possible to use an existing service, and it is not necessary to construct a service from scratch to provide a linkage service, so that a portal service can be created at a low cost.

  The information communication system, which is one of the foundations of future industrial development, is currently undergoing rapid growth. Whether or not the information source accessible through the huge amount of information communication can be fully utilized. It is a big problem now. The Kansei-based service linkage that is the present invention makes it possible to link existing services that could not be linked so far, and saves the trouble of creating a new service. In addition, since multiple services can be used across the basis of attractive service specifications that are sensibility from the user's point of view, it is not necessary to specify each service individually and decide each service. A new collaborative service is presented, saving the user trouble. Furthermore, it will lead to the promotion of the use of existing services that have not been used so far. In this way, by linking existing services across sensibilities and making them attractive services, service assets created in the past can be used with a user-friendly interface, and service creators (the same kind as providers) ) / User / service provider, it is possible to bring benefits to the three parties.
