- “type_station” is held as the slot type of the slot corresponding to the arrival station and the departure station. This means that “station” can be input as the word category for the slot.
- the slot type may be configured such that a word can be input when the word is a specific expression. For example, “to” (corresponding to to. * Type_station of the arrival station in FIG.
- a word may be input into a slot. Further, the “slot type” does not have to specify a specific category, and a word of an arbitrary category may be input. “Size” indicates the number of words input to the slot. “Mandatory?” Indicates whether or not input of a word is essential when executing the task. If there is no word to be input to the True slot in the “required?” Field, the slot content may be returned without executing the task, and the user may be prompted to input to the slot. .
- Each slot may be associated with information indicating whether a preset word (default word) is input when no word is input to the slot. For example, in the case of transfer guidance, for the departure station, the station name of the station closest to the current position of the user acquired by GPS (Global Positioning System) or the like may be input as a default word.
- GPS Global Positioning System
- the word input unit 12 is word input means for inputting information including words. Specifically, the word input unit 12 receives the information from the communication terminal 30 by receiving information indicating one or more words as a result of speech recognition by the speech recognition server 20. Alternatively, when the result of speech recognition by the speech recognition server 20 is a sentence (input sentence), the word input unit 12 receives the sentence and extracts the word from the sentence, or cuts the document into words. Get a word. In addition, the method of acquiring a word from sentences can use arbitrary conventional methods, such as a morpheme analysis using a morpheme dictionary.
- the word input to the word input unit 12 is a user's utterance unit for the communication terminal 30. That is, a word group included in one utterance is treated as one unit.
- the word input unit 12 inputs information indicating the acquired word to the category specifying unit 13.
- the category specifying unit 13 is a category specifying unit that specifies the category of the word input from the word input unit 12. Specifically, for example, the category specifying unit 13 stores in advance information for specifying a word category as shown in FIG. 3 and specifies the category based on the information. This information is previously input and stored in the function execution instruction server 10 by, for example, an administrator of the function execution instruction system 1 or the like. In this information, as shown in FIG. 3, a word is associated with a category ID and a category tag (category name) that are information for specifying a category. One category ID and category tag are associated with one or more words.
- the category specifying unit 13 determines whether or not each word input from the word input unit 12 matches the word included in the information shown in FIG.
- the attached category is specified as the category of the word input from the word input unit 12.
- the category specifying unit 13 may specify the category by, for example, the technique of specific expression extraction (Named Entity Extraction) without using the information indicating the correspondence between the category and the word as shown in FIG. .
- the category specifying unit 13 may store a regular expression in advance and specify the category depending on whether or not the word matches the stored regular expression. For example, if a word matches a regular expression, the word is identified as a category that matches the regular expression.
- the category specifying unit 13 may acquire the phone book data stored in the communication terminal 30 and specify the category by determining whether or not the word is a word included in the phone book data. For example, when a word is included in the phone book data, the word is specified as a category of words existing in the phone book data.
- the category identification unit 13 outputs information indicating the word input from the word input unit 12 and the category of the identified word to the execution function determination unit 14. Note that it is not always necessary to specify a category for each word, and there may be a word for which no category is specified.
- the execution function determination unit 14 is an execution function determination unit that determines a task whose execution is instructed by the function execution instruction unit 11 according to the category specified by the category specification unit 13. For example, the execution function determination unit 14 determines a task that is instructed to be executed based on the association (association) between a task and a category as described above. Specifically, the score of the category is stored for each task, the score of the word input in the user's utterance unit is specified, and the task to be instructed to execute is determined based on the specified score. The score of each category is determined according to the degree of association with the task.
- the user's utterance is “transfer to Tokyo”.
- the user's utterance is divided into the words “Tokyo”, “To”, “No”, and “Transfer”.
- the score of the category matched with each word for every task is calculated
- the score of each word is specified, and by summing them, the score of each task (in the example of FIG. 4, "transfer guide”, “gourmet search”, “map search” tasks) is totaled.
- the score may be determined not only for the category but also for each word.
- a task to be instructed to execute may be determined based on a word input by the word input unit 12 and a preset word.
- the execution function determination unit 14 determines, for example, the task having the highest score as a task whose execution is instructed by the function execution instruction unit 11.
- the execution function determination unit 14 notifies the function execution instruction unit 11 of the determined task.
- the function execution instructing unit 11 instructs the communication terminal 30 to execute the task.
- a word that is input to the slot of the task to be executed (a word whose category matches the category of the slot) is also notified. Also good.
- a word to be input to the slot is also transmitted from the function execution instruction unit 11 to the communication terminal 30 together with the task execution instruction.
- the word “Tokyo” in the “station” category is associated with the word in the “station” category. It is used as an input for a station slot.
- the station name of the station closest to the current position of the user is input as a default word.
- the transfer from the nearest station to the Tokyo station from the current position of the user is searched, and the result is presented to the user.
- the user may be prompted to input to the slot at that time, and the word to be input to the slot may be input again.
- the execution function determining unit 14 determines a task to be instructed to be executed by the function execution instructing unit 11 from now on. The determination of this task is assigned to the task instructed to be executed by the function execution instructing unit 11 in the past. It may be based on. Specifically, it is determined whether or not a task for which execution has been instructed in the past is to be executed subsequently. For example, if execution of the task of “transfer guidance” has been instructed in the past (the task has been executed), and then a word input based on the user's utterance has been input to the function execution instruction server 10, It is determined whether to instruct the execution of the task of “transfer guidance” continuously. A configuration for this will be described below.
- the execution function storage unit 15 is an execution function storage unit that stores a task instructed to be executed by the function execution instruction unit 11. For example, the execution function storage unit 15 inputs information (for example, task name) indicating a task for which execution has been instructed from the function execution instruction unit 11, and stores information indicating the input task. At this time, the task execution instruction time may be stored together. The execution function storage unit 15 also inputs a word input to the slot at the time of task execution instruction from the function execution instruction unit 11, and stores the word together with the executed task. Also good.
- the information stored in the execution function storage unit 15 is appropriately referred to by the execution function determination unit 14 as follows.
- the execution function determination unit 14 is a category related to (associated with) the category specified by the category specification unit 13 and the task stored in the execution function storage unit 15 and instructed to be executed by the function execution instruction unit 11 in the past. Based on the above, it is determined whether or not to instruct execution of the task that has been instructed to be executed by the function execution instruction unit 11 in the past. At this time, the task for determining whether or not to instruct execution is the task that is instructed to be executed by the function execution instructing unit 11 immediately before a word is input to the function execution instructing server 10 (one time before. It may be determined whether or not to instruct execution of a task for which execution is instructed.
- a task for which execution has been instructed two or more times before may not be a target of a task for which execution is instructed continuously. Furthermore, only tasks that are instructed to be executed within a predetermined time (for example, within 1 hour) set in advance from the word input may be set as candidate tasks to be instructed to be executed subsequently.
- the execution function determination unit 14 includes a category related to (associated with) a task that has been instructed by the function execution instruction unit 11 in the past and stored in the execution function storage unit 15, and a category specification unit 13. It is determined whether or not the category specified by (1) matches, and according to the determination, it is determined whether or not to instruct execution of the function that has been instructed by the function execution instructing unit 11 in the past. For example, the execution function determining unit 14 matches the category of the word specified by the category specifying unit 13 with the category associated with the slot of the task whose execution has been instructed by the function execution instructing unit 11 in the past (category The above determination is made by determining whether the word specified by the specifying unit 13 can be input to the task slot.
- the execution instruction in the past If it is determined that the task to be executed is instructed to be executed continuously, and it is determined that the tasks do not coincide with each other, it is determined that the instruction to continue execution of the task is not performed, that is, the execution of a new task is instructed.
- the execution of the task is instructed only when the category of the word specified by the category specifying unit 13 coincides with all the categories associated with the task slots instructed to be executed by the function execution instructing unit 11 in the past. It may be possible to instruct the execution of the task when it matches the category associated with a part of the slot. Further, only when the category of the word specified by the category specifying unit 13 matches the category associated with any of the task slots instructed to be executed by the function execution instructing unit 11 in the past, the task execution is continued. (That is, all the categories of the words specified by the category specifying unit 13 match the category corresponding to any of the task slots for which execution has been instructed by the function executing unit 11 in the past, and are input.
- the task may be instructed to continue only when there is no noun that does not correspond to any category in the sentence and therefore does not correspond to any slot.
- Some categories of the designated words are slotted for tasks for which execution has been instructed by the function execution instructing unit 11 in the past. May instruct the execution of the tasks subsequent when matching the categories marked with corresponding to any one of. If the slot of the task whose execution has been instructed in the past by the function execution instructing unit 11 is not of a type that specifies a category (if it is a type in which words of an arbitrary category can be input, for example, for the task of “image search” The “search word” slot) may be instructed to always execute a task regardless of which category of word is input, so the above determination may not be performed.
- the execution function determination unit 14 determines that a task for which execution has been instructed in the past by the function execution instruction unit 11 is to be executed (to continue the task), the category associated with the slot The function execution instructing unit 11 is instructed to execute the word that matches with the input to the slot.
- the execution function determination unit 14 sets, as a part of (or all) a task slot, the word input to the past slot stored by the execution function storage unit 15 as an input to the task. Also good. In this case, in each slot of the task shown in FIG. 2, even if the input of the word is performed only when the information in the “takeover?” Column is information indicating that the input of the word is inherited (True). Good. If the execution function determination unit 14 determines that the task is not continuously executed by the above determination, the execution function determination unit 14 determines an instruction to execute the task based on the score described above.
- “transfer guidance” is displayed in the execution function storage unit 15 as a task for which execution has been instructed in the past.
- the word “Tokyo” is stored as an input of the arrival station slot. Assume that the user's utterance after that is “Yokohama”. In this case, since the word “Yokohama” is the “station” category, it is determined that it matches the category associated with the slot of the arrival station of the “transfer guidance” task executed in the past. Therefore, it is determined that the “transfer guidance” task executed in the past is continuously instructed to be executed again. At that time, “Yokohama” is entered in the slot of the arrival station. As for the departure station, the station name of the nearest station from the current position of the user is inherited as in the case of “transfer to Tokyo” (the “takeover” column of the departure station is True as shown in FIG. 2). ing).
- the score is determined by the utterance “Yokohama” without determining whether or not the execution function determination unit 14 continues to instruct execution of the task as described above.
- the user's utterance is divided into the words “after all” and “Yokohama”. Then, as in the above-described example, the score of each word is specified for each task, and these are added together to calculate the score for each task.
- the highest score is “map search” in which the score is high only by the place name “Yokohama”, not “transfer guidance”. It becomes.
- the execution function determination unit 14 determines a task instructing execution by calculating a score based on an utterance “curry”. As shown in FIG. 6, the user's utterance is composed only of the word “curry”. Then, as in the example described above, the score of the category associated with each word is specified for each task, and these are added together to calculate the score for each task. In this case, “gourmet search” has the highest score, and it is determined that the task of “gourmet search” is executed. If the user utters “curry” after the user utters “transfer to Tokyo”, it is a completely different topic, so he would like to know information about “curry” instead of “transfer guidance”. As described above, in this case, the task score is not determined to be taken over, but the task score is calculated from the user's utterance, and the execution of the task of “gourmet search” is instructed.
