5. Functional Configuration of Information Processing Apparatus (Mobile Device)
The CPU 21 of the mobile device 20 loads an information processing program, which is stored in the ROM 22, in the RAM 23, and executes the information processing program. When the CPU 21 of the mobile device 20 executes the information processing program, the CPU 21 of the mobile device 20 operates as the text obtaining unit 210, the keyword extracting unit 211, the maintenance-information obtaining unit 212, the activity-history obtaining unit 213, the status finding unit 214, the image recognizing unit 215, the sort-out unit 216, the maintenance-information providing unit 217, and the database improvement unit 218.
The text obtaining unit 210 obtains a text indicating an issue occurred in the MFP 10.
The keyword extracting unit 211 tokenizes the text (text indicating an issue occurred in the MFP 10) obtained by the text obtaining unit 210 (morphological analysis). The keyword extracting unit 211 filters the plurality of words obtained by tokenizing the text to thereby extract a noun(s) and a modifier(s) as a keyword(s) (one or plural). In the present embodiment, “modifiers” may at least include words that modify nouns. For example, “modifiers” at least include adjectives.
The maintenance-information obtaining unit 212 searches the local database 220 and the global database 221 stored in the memory device 24, and retrieves a maintenance-information-item(s) (one or plural) in association with the extracted keyword(s). The “maintenance-information-item” is information about a solution to an issue occurred in the MFP 10, and is an entry that links with data that records a method of a solution, for example. Hereinafter, the “maintenance-information-item” will be simply referred to as “entry”.
The activity-history obtaining unit 213 receives an activity-history/histories from the MFP 10 via the network communication interface 25 or the near field communication interface 29. The activity-history obtaining unit 213 finds an activity-history/histories in association with the keyword(s) from all the received activity-history/histories.
The status finding unit 214 receives the current-status of the MFP 10 via the network communication interface 25 or the near field communication interface 29. The status finding unit 214 finds an issue on a basis of the current-status received from the MFP 10.
The image recognizing unit 215 recognizes an object(s) of the MFP 10 in an image taken by the camera 202.
The sort-out unit 216 sorts out (in other words, narrows down) an entry/entries (one or plural) having a higher relation with the occurred issue from the entries (plural) retrieved by the maintenance-information obtaining unit 212.
The maintenance-information providing unit 217 provides an entry/entries (one or plural), which is/are obtained by the maintenance-information obtaining unit 212 and sorted out by the sort-out unit 216, to a user.
The database improvement unit 218 sends the provided entry/entries (one or plural) and the keyword to the server apparatus 30, and the server apparatus 30 stores the entry/entries (one or plural) and the keyword(s) in association with each other in the local database 220 and the global database 221.
6. Operation of Information Processing Apparatus
Before starting the flowchart, an issue occurs in the MFP 10 used by a user. The user inputs a voice indicating an issue occurred in the MFP 10 (for example, “Paper jam has occurred”, “There is a black spot in scanned document”, etc.) in the microphone 201 of the mobile device 20. Alternatively, the user inputs a text indicating an issue occurred in the MFP 10 (same as above) in the touchpad 26a of the mobile device 20.
The text obtaining unit 210 obtains the voice (sound data) input in the microphone 201 and converts the voice (sound data) into a text. Alternatively, the text obtaining unit 210 obtains the text input in the touchpad 26a. In this way, the text obtaining unit 210 obtains a text indicating an issue occurred in the MFP 10 (electronic apparatus) (Step S1).
The keyword extracting unit 211 tokenizes the text (text indicating an issue occurred in the electronic apparatus) obtained by the text obtaining unit 210 (morphological analysis) (Step S2). For example, the keyword extracting unit 211 tokenizes the text “Paper jam has occurred” into a plurality of words “paper”, “jam”, “has”, and “occurred”. Alternatively, the keyword extracting unit 211 tokenizes the text “There is a black spot in scanned document” into a plurality of words “there”, “is”, “a”, “black”, “spot”, “in”, “scanned”, and “document”.
The keyword extracting unit 211 filters the plurality of words obtained by tokenizing the text, and thereby extracts a noun(s) and/or a modifier(s) as a keyword(s) (one or plural) (Step S3). For example, the keyword extracting unit 211 extracts the nouns “paper” and “jam” as keywords from the plurality of words “paper”, “jam”, “has”, and “occurred” obtained by tokenizing the text. Alternatively, the keyword extracting unit 211 extracts the nouns “document” and “spot” and the modifiers “scanned” and “black” as keywords from the plurality of words “there”, “is”, “a”, “black”, “spot”, “in”, “scanned”, and “document” obtained by tokenizing the text.
The maintenance-information obtaining unit 212 searches the local database 220 stored in the memory device 24, and retrieves a maintenance-information-item(s) (one or plural) in association with the extracted keyword(s) (Step S4). The “maintenance-information-item” is information about a solution to an issue occurred in the MFP 10, and is an entry that links with data that records a method of a solution, for example. Hereinafter, the “maintenance-information-item” will be simply referred to as “entry”. The local database 220 records keywords and entries in association with each other. The local database 220 stores feedbacks obtained from mobile devices owned by users that use MFPs in a limited region (company that has the MFP 10, the sales region of the MFP 10, etc.).
If the maintenance-information obtaining unit 212 retrieves no entry in association with the keyword(s) from the local database 220 (alternatively, if the number of retrieved entry/entries is smaller than a predetermined value), the maintenance-information obtaining unit 212 may search the global database 221 stored in the memory device 24, and may retrieve an entry/entries in association with the keyword(s). Similar to the local database 220, the global database 221 also records keywords and entries in association with each other. The global database 221 stores a wider range of information than information stored in the local database 220. For example, the global database 221 stores feedbacks obtained from mobile devices owned by users that use MFPs in a wider region (all the companies that have MFPs of the same model, all the sales regions of MFPs of the same model, etc.).
Note that the mobile device 20 has downloaded the local database 220 and the global database 221 from the server apparatus 30 via the network N at regular timings or at triggered timings.
Meanwhile, the activity-history obtaining unit 213 receives activity-history/histories from the MFP 10 via the network communication interface 25 or the near field communication interface 29 (Step S5). Examples of “an activity-history/histories” may include a history/histories of services executed by the MFP 10 and/or a diagnostic history/histories for issues occurred. In detail, the activity-history obtaining unit 213 sends a request to the MFP 10, and receives the predetermined number of recent activity-history/histories (one or plural) from the MFP 10. The activity-history obtaining unit 213 finds an activity-history/histories in association with the keyword(s) from all the received activity-history/histories (Step S5a). For example, the activity-history obtaining unit 213 finds an activity-history/histories containing the keyword(s) as an activity-history/histories in association with the keyword(s).
Meanwhile, the status finding unit 214 receives the current-status of the MFP via the network communication interface 25 or the near field communication interface 29 (Step S6). The status finding unit 214 may receive data containing the current-status. Alternatively, the status finding unit 214 may receive image data of a status page, may optically recognize the received image data (OCR, optical character recognition), and may capture a status described in a text. The status may include, for example, an error code, a message, and the like. The status finding unit 214 finds an issue in the current-status received from the MFP 10 (Step S6a).
Meanwhile, the user operates the mobile device 20, and the camera 202 thereby takes an image of an object, in which an issue has occurred, of the MFP 10 to obtain the image (Step S7). Examples of “an object in which an issue has occurred” may include a feeder (if issue is paper jam) and a platen (if issue is black spot in scanned document). The image recognizing unit 215 recognizes the object of the MFP 10 in the image taken by the camera 202 (Step S7a).
The sort-out unit 216 sorts out (in other words, narrows down) an entry/entries (one or plural) having a higher relation with the occurred issue from the entries (plural) retrieved by the maintenance-information obtaining unit 212 (Step S8). Specific examples of the sort-out methods (1) to (4) will be described below.
(1) The sort-out unit 216 may sort out an entry/entries (one or plural) on a basis of registration date(s) of entry/entries, occurrence of the keyword(s) (number of feedbacks obtained from mobile devices), and/or occurrence of the issues in association with the entry/entries. For example, the sort-out unit 216 may sort out an entry/entries (one or plural) whose registration date(s) is/are newer, whose occurrence of the keyword(s) (number of feedbacks obtained from mobile devices) is higher, and/or whose occurrence of the issues in association with the entry/entries is higher.
(2) The sort-out unit 216 may sort out an entry/entries (one or plural) having a higher relation with the activity-history/histories (Step S5a) obtained by the activity-history obtaining unit 213 from the entries (plural) retrieved by the maintenance-information obtaining unit 212. For example, the sort-out unit 216 may sort out an entry/entries (one or plural) having a higher relation with the activity-history/histories of the new (recent) date(s).
(3) The sort-out unit 216 may sort out an entry/entries (one or plural) having a higher relation with the issue (Step S6a) found by the status finding unit 214 from the entries (plural) retrieved by the maintenance-information obtaining unit 212. For example, the sort-out unit 216 may sort out an entry/entries (one or plural) for a solution(s) to the issue found by the status finding unit 214.
(4) The sort-out unit 216 may sort out an entry/entries (one or plural) having a higher relation with the object (Step S7a) recognized by the image recognizing unit 215 from the entries (plural) retrieved by the maintenance-information obtaining unit 212. For example, if the object is a feeder, the sort-out unit 216 may sort out an entry/entries (one or plural) for a solution(s) to an issue(s) (paper jam, etc.) that can occur in the feeder. Alternatively, if the object is a platen, the sort-out unit 216 may sort out an entry/entries (one or plural) for a solution(s) to an issue(s) (black spot in scanned document, etc.) that can occur in the platen.
The sort-out unit 216 may execute all the aforementioned four sort-out methods (1) to (4), any three of those, any two of those, or any one of those. For example, if a user does not operate the mobile device 20 and the camera 202 thus does not take an image of an object to obtain no image (Step S7), the sort-out unit 216 cannot execute the method (4). In this case, the sort-out unit 216 may execute all the three sort-out methods (1) to (3), any two of those, or any one of those.
The sort-out unit 216 may put a higher priority/priorities on one/some of the sort-out methods (1) to (4), and may put a lower priority/priorities on the other(s). For example, the sort-out unit 216 may put the highest priority on the sort-out method (1), the second-highest priority on the sort-out method (2), the third-highest priority on the sort-out method (3), and the lowest priority on the sort-out method (4).
Note that, if the number of the entries (plural) retrieved by the maintenance-information obtaining unit 212 is a predetermined value or less, the sort-out unit 216 may omit the sort-out process (Step S8).
The maintenance-information providing unit 217 provides an entry/entries (one or plural), which is/are obtained by the maintenance-information obtaining unit 212 and sorted out by the sort-out unit 216, to the user (Step S9). For example, the maintenance-information providing unit 217 displays the entry/entries (one or plural) on the display device 27 to thereby provide the entry/entries (one or plural) to the user.
The database improvement unit 218 sends the provided entry/entries (one or plural) and the keyword(s) to the server apparatus 30, and the server apparatus 30 stores the entry/entries (one or plural) and the keyword in association with each other in the local database 220 and the global database 221 (Step S9a). The server apparatus 30 configures mapping (linking) between the entry/entries (one or plural) received from the mobile device 20 and the keyword(s) received from the mobile device 20 to thereby improve the local database 220 and the global database 221.
Meanwhile, if the maintenance-information obtaining unit 212 obtains no entry in association with the keyword (Step S8a, NO), the keyword extracting unit 211 may filter the plurality of words obtained by tokenizing the text (Step S2), and may extract a word(s) other than nouns and modifiers as a keyword(s) (one or plural) (Step S3). Then, the processes on and after Step S4 are repeated.
In the following description, configurations, processes, and the like similar to those described above will be denoted by similar reference symbols and description thereof will be omitted.

Instead of those embodiments, the mobile device 20 and the server apparatus 30 may share the processes of extracting keyword(s), obtaining maintenance-information-item, and sorting out (not shown).
Alternatively, if the MFP 10 includes all the configuration of the mobile device 20 and the server apparatus 30, the MFP 10 may execute the processes of extracting keyword(s), obtaining maintenance-information-item, and sorting out (not shown).
If there is no result (Step S8a or S38a, NO), the retry process may be executed by using all the following methods (a) to (d), any three of those, any two of those, or any one of those.
(a) Change search keywords. Add a different part of speech to keywords. Automatically generate additional keywords by lemmatization. Reduce number of keywords.
(b) Change database. Use a global database to retrieve information.
(c) Check similar devices. Discover similar devices in the network N and retrieve service or diagnostic records.
(d) Change filtered date. Retrieve record from older date.
According to the present disclosure, there is provided a method of providing a MFP maintenance procedure by using a combination of tokenizing user keyword inputs, checking prior service/diagnostic histories and current device status, and taking a photo of a defective parts, to provide a most relevant solution to the user. Multiple search and filter narrow down the cause.
Too many search results obscures relevant information. By providing only a relevant information reduces amount of time spent to service a device. Filtering unrelated results reduces error by incorrectly applying wrong maintenance procedures. Retrieving service/diagnostic information may reveal hidden or root cause.
It should be understood by those skilled in the art that various modifications, combinations, sub-combinations and alterations may occur depending on design requirements and other factors insofar as they are within the scope of the appended claims or the equivalents thereof
