detailed description

It is understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

An embodiment of the present invention provides a method for extracting key content of a call. As shown in FIG. 1 , a schematic flowchart of a method for extracting a key content of a call according to the present invention is shown.

S10. When it is detected that a call is established, the duration of the call is counted, and the call is recorded;

The call key content extraction method can be implemented on any terminal having a call function, for example, a smart phone. When the user receives an incoming call and answers the call, or the user calls out and the other party answers the call, the call connection is successfully established between the terminal used by the user and the terminal used by the other party. When the terminal used by the user detects that a call is established, the real time duration of the call may be counted by a timer set on the terminal, and the call is recorded by a recording device set on the terminal, where The recorded content obtained by the call recording can be stored in the buffer first.

S20. When the duration of the call is greater than or equal to the preset duration, determine a set of keywords related to the call according to the acquired information related to the call and a preset keyword determining mechanism.

At the end of the call, the total duration of the call and the size of the preset duration obtained by comparing statistics may be performed after the total duration of the call is greater than or equal to the preset duration; During the process of the call, when the calculated real-time duration of the call is greater than or equal to the preset duration, a subsequent operation may be performed.

The preset duration is a preset duration value, for example, 1 minute or 30 seconds, which can be set by the user or set by the terminal as a default value; the duration of each call obtained by the statistics can be accurate to minutes and seconds. . By comparing the duration of each call with the preset duration, some unimportant calls can be filtered out, the call key content is not extracted, and the calls are recorded in the buffer when the calls are over. The recorded content is deleted to save mobile phone storage space and reduce the running pressure and power consumption of the background system. Unimportant calls, usually a few seconds, ten seconds of phone calls, such as some courier calls, advertising marketing, harassing calls, wrong calls, etc. that people often receive, these calls are usually a few seconds after being connected. The left and right will be hung up, and there is basically no need to save the key content of the call. If you do not filter beforehand, The recording and extraction of all the call recordings will inevitably bring great pressure to the running speed and power consumption of the mobile phone. Therefore, by using the preset duration to limit, it is necessary to filter out these unnecessary calls in advance, and to alleviate the running pressure in the background and the memory consumption of the buffer.

When performing the subsequent operations, the terminal may obtain some history information related to the call by querying various applications installed in the installed application or the storage file, thereby obtaining a history related to the call, and then according to the preset keywords. The determining mechanism extracts a set of keywords related to the call from the obtained history. The keyword determining mechanism is configured to specify, according to information related to the call in different applications or stored files, keywords related to the call, where the keyword determining mechanism is preset A variety of extraction rules, which stipulate the extraction range of keywords, and also provide a massive vocabulary of keywords.

Further, referring to FIG. 2, the foregoing step S20 specifically includes:

S21. Search for a history related to the counterpart number in the call from the specified application.

The specified application may be any application installed on the terminal. In this embodiment, the specified application is preferably a common tool application such as a calendar, an alarm clock, a memo, or a notepad installed on various terminals. In these designated applications, if an item or record related to the counterpart number in the call is stored, the terminal can obtain a history related to the counterpart number in the call by querying. For example, suppose that the alarm application stores a reminder related to the other party number in the call, such as the cooperation with the general manager at 9:00 am on March 15, 2016 (where the terminal address book stores Wang Zong) The phone number, that is, the other party number in the call), the notebook application stores two records related to Wang Zong. For example, the company’s main production communication equipment, Wang’s company address is Nanshan District, Shenzhen. In the Science and Technology Park, the terminal can obtain 3 historical records in the two applications through inquiry.

S22. Extract keywords from one or more historical records according to the keyword determining mechanism according to an order in which the creation time of the history records is from large to small.

The first threshold and the second threshold are preset in the keyword determining mechanism, where the first threshold and the second threshold are two fixed values, wherein the second threshold is greater than the first threshold, where The value can be set by the user or the terminal according to the actual demand. The two thresholds are set to protect The number of keywords extracted by the certificate is not too small or too much, and the key content of the call that is subsequently extracted is less or more.

Assuming that the history recorded in the alarm application is created later than (ie, greater than) the creation time of the two history records in the notebook, the history record in the alarm is the latest information. At this time, the terminal follows the history. The order of creation of records is from the largest to the smallest, first extracting keywords from the history record in the alarm application, and assuming that the keywords extracted according to the keyword determination mechanism are "March 15, 2016" "Morning" 9:00" "Wang total" "negotiation" "cooperation", a total of 5 keywords. If the first threshold is greater than 5, it means that the number of keywords extracted according to the history record in the alarm application is small. In this case, the history may be created from a history record with a larger time in the two history records of the notebook. Extracting, assuming that another keyword is extracted, if the total number of keywords extracted at this time satisfies the condition that is greater than or equal to the preset first threshold and less than or equal to the preset second threshold, no extraction is required. The six keywords obtained at this time are a set of keywords to be extracted; if the first threshold is also greater than 6, it means that the number of keywords extracted according to the two historical records is still insufficient, and at this time, it is necessary to The third history record continues to extract keywords until the condition that the total number of extracted keywords is greater than or equal to the first threshold and less than or equal to the second threshold is satisfied.

Further, the above step S20 further includes:

If the total number of keywords extracted from the existing three historical records is still less than the first threshold, the appropriate number of the keywords may be determined from the keyword vocabulary of the keywords according to the keyword determining mechanism. The keyword is added; if the total number of extracted keywords is greater than the second threshold, then according to the keyword determining mechanism, an appropriate number of keywords may be removed. It should be noted that among the extracted keywords, each keyword is different.

S30. Extract call content from the recorded content of the call according to the determined set of keywords.

After extracting a set of keywords, the terminal gradually converts all or part of the recorded content of the call into text content, and then performs fuzzy matching or similar matching of the obtained set of keywords with the text content, thereby The call key content of the call is extracted.

When the call ends the call, the recorded content of the call stored in the buffer may be stored in a designated storage area of the terminal, so that the user can retrieve the call recording of the call afterwards.

The method for extracting the key content of the call provided by the embodiment of the present invention, when the call is established, the duration of the call is counted and the call is recorded, and when the duration of the call is greater than or equal to the preset duration, the obtained call is obtained. Information related to the call, and a preset keyword determining mechanism, determining a set of keywords, and extracting key content of the call from the recorded content of the call according to the obtained set of keywords, and realizing the call The automatic extraction of the important information in the content, thereby obtaining the key content of the call of the call, and facilitating the subsequent convenient service for the user to provide various uses based on the extracted key content of the call.

The second embodiment of the call key content extraction method of the present invention is proposed based on the first embodiment. In this embodiment, referring to FIG. 3, after the call key content is extracted, the call key content extraction method further includes:

S40. Save the extracted call key content.

After extracting the call key content of the call, the terminal may save the call key content in a designated storage location or a designated application of the terminal, so that the user can view it at any time. It can be understood that the terminal can also convert the obtained call key content into a file in a voice format for storage, and when the user views the key content of the call, the call key content is delivered to the user by means of voice broadcast.

After extracting the call key content of the call, the call key content is stored, so that the user can view at any time, so that the user can receive the call intently during the call without recording the key content while answering the phone, thereby saving the user's operation. And the energy consumed, it also facilitates users to get key content of the call.

Wherein, the above step S40 includes:

When saving the call key content of the call, if the call key content includes a date and/or time, the terminal may use an application with a reminder function (for example, a calendar or an alarm clock) to establish a reminder, and then call the call The key content is added to the reminder in accordance with the reminder, for example, the date of the key content of the call "May 1, 2016, 6:00, Xiao Wang, KFC, and dinner", "May 1, 2016" , set to the date of the new reminder of the specified application calendar, set the "6 o'clock" in the key content of the call to the time of the reminder, the "key king, KFC, eat" of the key content of the call, Set to the title or note of the reminder. After the automatic setting of the reminder is completed, the terminal can provide the setting page to the user, and the user can add or modify the setting according to individual needs, and the user can also set how long to advance the reminder. After the user setting is completed and saved, the terminal will remind the user of the item according to the setting of how long to remind the reminder before the time corresponding to the set date and time. Wherein, when the reminder is set in advance, the designated time is a time when the reminder is issued in advance with respect to the set date and time, and when the reminder is not set in advance, the specified time is the set date and time corresponding to the set time Moment.

If the date and/or time is not included in the call key content, the terminal may use the text type application to store the call key content, for example, the call key content may be stored in a memo or a notebook, so that the user can View.

The call key content extraction method is provided in the embodiment of the present invention, and the extracted call key content is separately stored according to whether the date and/or time is included, so as to include the date and/or time of the call key content in the form of a reminder item. Storage, easy to remind users of the corresponding matters, to avoid the handling of important things, and to store the key content of the call without date and / or time in the text type of application, so that users can view at any time, eliminating the need to remember The trouble makes the user more worry-free during the call.

The third embodiment of the call key content extraction method of the present invention is proposed based on the foregoing second embodiment. In this embodiment, the foregoing step S20 specifically includes:

The terminal can obtain the contact details of the other party's number in the address book according to the other party's number of the call, and some important information may be stored in the contact details, and the information may be extracted as a keyword.

Further, the above step S20 further includes:

Assume that the contact details obtained according to the other party number of the call are: "Name: Xiao Li, company: chain home agency, occupation: housing agency, remarks: degree room, primary school", then "Xiao Li" "chain home" "House agency", "degree room" and "primary school" as keywords and develop intelligent associations to get more relevant keywords. If the total number of keywords obtained is less than the first threshold, an appropriate number of related keywords may be selected from the mass vocabulary of the keyword determining mechanism keyword, thereby causing a set of keywords The total number of times is greater than or equal to the first threshold and less than or equal to the second threshold. If the total number of keywords obtained is greater than the second threshold, then according to the keyword determining mechanism, an appropriate number of keywords may be removed. It should be noted that among the extracted keywords, each keyword is different.

The method for extracting key content of the call provided by the embodiment of the present invention extracts a keyword from the contact details of the address book corresponding to the other party number in the call, and the method can obtain a more accurate keyword, which is beneficial to the call from the call. The recorded content extracts more accurate call key content.

It can be understood that there are two embodiments of the method for extracting the key content of the call. (1) In the above step S20, the keyword is extracted by using the extraction method of the first embodiment, and the total number of keywords extracted is less than When the first threshold is used, the keyword is extracted by using the extraction method of the third embodiment, and if the total number of keywords extracted in the two extraction modes meets the first threshold and is less than or equal to When the condition of the second threshold is described, all the keywords extracted are the set of keywords to be obtained; if the total number of keywords extracted in the two extraction modes does not satisfy the first threshold and If the condition is less than or equal to the second threshold, then the appropriate number of keywords are supplemented or screened according to the keyword determining mechanism.

(2) In the above step S20, the keyword is extracted by using the extraction method of the third embodiment, and when the total number of extracted keywords is less than the first threshold, the extraction method of the first embodiment is used. Extracting a keyword, if the total number of keywords extracted in the two extraction modes satisfies a condition greater than or equal to the first threshold and less than or equal to the second threshold, all the extracted keywords are a set of keywords obtained; if the total number of keywords extracted in the two extraction modes does not satisfy a condition greater than or equal to the first threshold and less than or equal to the second threshold, then according to the key The word determination mechanism supplements or screens the appropriate number of keywords.

The combination of the two extraction methods can extract the appropriate and more accurate keywords, and extract the key content of the call according to the extracted keywords, and make the data foundation, which is most accurate and useful for extracting to the call. Information.

The fourth embodiment of the call key content extraction method of the present invention is proposed based on the foregoing third embodiment. In this embodiment, when the extracted call key content is empty, the call key content extraction method further includes:

The keyword extracted from the information related to the call, or the keyword extracted from the mass vocabulary in the keyword determining mechanism, sometimes the text content corresponding to the recorded content of the call is irrelevant In this case, the key content of the call extracted at this time may be air. In order to make the key content of the call provided to the user not empty, words specifying the part of speech, such as nouns, quantifiers, verbs, etc., may be extracted from the text content corresponding to the recorded content as the key content of the call.

The call key content extraction method according to the embodiment of the present invention, when the extracted key content is empty according to the information related to the call and the keyword determination mechanism, The words corresponding to the part of speech are extracted from the text content corresponding to the recorded content, thereby ensuring that the extracted key content of the call is not empty, and providing the user with certain useful information.

The embodiment of the present invention further provides a call key content extracting apparatus. As shown in FIG. 4, a schematic diagram of a function module of the first embodiment of the call key content extracting apparatus of the present invention is shown. The call key content extracting apparatus includes:

The timing module 100 is configured to count the duration of the call when a call establishment is detected;

The recording module 200 is configured to record the call when a call establishment is detected;

The call key content extraction device may be disposed on any terminal having a call function, such as a smart phone. When the user receives an incoming call and answers the call, or the user calls out and the other party answers the call, the call connection is successfully established between the terminal used by the user and the terminal used by the other party. When the terminal used by the user detects that a call is established, the timing module 100 can count the real-time duration of the call by using a timer set on the terminal, and the recording module 200 records the call by using a recording device set on the terminal. The recorded content obtained by recording the call may be stored in a buffer first.

The determining module 300 is configured to: when the duration of the call is greater than or equal to a preset duration, determine a group related to the call according to the acquired information related to the call and a preset keyword determining mechanism Key words;

The preset duration is a preset duration value, for example, 1 minute or 30 seconds, which can be set by the user or set by the terminal as a default value; the duration of each call obtained by the statistics can be accurate to minutes and seconds. . By comparing the duration of each call with the preset duration, some unimportant calls can be filtered out, the call key content is not extracted, and the calls are recorded in the buffer when the calls are over. The recorded content is deleted to save mobile phone storage space and reduce the running pressure and power consumption of the background system. Unimportant calls, usually a few seconds, ten seconds of phone calls, such as some courier calls, advertising marketing, harassing calls, wrong calls, etc. that people often receive, these calls are usually a few seconds after being connected. The left and right will be hung up, and there is basically no need to save the key content of the call. If you do not perform filtering and filtering beforehand, all the recordings of all calls will be cached and extracted, which will inevitably put a lot of pressure on the running speed and power consumption of the mobile phone. Therefore, by using the preset duration to limit, it is necessary to filter out these unnecessary calls in advance, and to alleviate the running pressure in the background and the memory consumption of the buffer.

When the subsequent operations are performed, the determining module 300 of the terminal may obtain some history information related to the call by querying various applications or storage files installed in the terminal, thereby obtaining a history related to the call, and then according to the pre- The keyword determining mechanism extracts a set of keywords related to the call from the obtained history record. The keyword determining mechanism is configured to specify, according to information related to the call in different applications or stored files, keywords related to the call, where the keyword determining mechanism is preset A variety of extraction rules, which stipulate the extraction range of keywords, and also provide a massive vocabulary of keywords.

Further, referring to FIG. 5, the determining module 300 includes:

The searching unit 301 is configured to search for a history related to the counterpart number in the call from the specified application;

The specified application may be any application installed on the terminal. In this embodiment, the specified application is preferably a common tool application such as a calendar, an alarm clock, a memo, or a notepad installed on various terminals. In these designated applications, if an item or record related to the counterpart number in the call is stored, the search unit 301 of the terminal can obtain a history related to the counterpart number in the call by querying. For example, assume that the pair in the call is stored in the alarm application. A reminder related to the party number, such as 9:00 am on March 15, 2016, to discuss cooperation with Wang. (The terminal address book stores the telephone number of Wang, that is, the number of the other party in the call) The Notepad application stores two records related to Wang Zong. For example, the company's main production communication equipment, Wang's company address is Shenzhen Nanshan District Science and Technology Park, the terminal's search unit 301 can be obtained through inquiry. 3 historical records in both applications.

The first extracting unit 302 is configured to extract keywords from one or more historical records according to the keyword determining mechanism in descending order of creation time of the history.

The first threshold and the second threshold are preset in the keyword determining mechanism, where the first threshold and the second threshold are two fixed values, wherein the second threshold is greater than the first threshold, where The value can be set by the user or the terminal according to the actual demand. The two thresholds are set to ensure that the number of keywords to be extracted is not too small or too much, and the key content of the subsequent extraction is less or more.

Assuming that the history recorded in the alarm application is created later than (ie, greater than) the creation time of the two history records in the notebook, the history record in the alarm is the latest information, and at this time, the terminal An extracting unit 302 first extracts keywords from the history record in the alarm clock application in descending order of the creation time of the history record, and assumes that the keyword extracted according to the keyword determining mechanism is “2016 3 On the 15th of the month, "9:00 am" "Wang Zong", "Consultation" and "Cooperation", a total of 5 keywords. If the first threshold is greater than 5, it indicates that the number of keywords extracted according to the history in the alarm application is small. At this time, the first extracting unit 302 can create a larger time from the two historical records of the notebook. Continue to extract from a history record, assuming that another keyword is extracted, if the total number of keywords extracted at this time satisfies a condition that is greater than or equal to the preset first threshold and less than or equal to the preset second threshold. , the need to extract again, the six keywords obtained at this time is a set of keywords to be extracted; if the first threshold is also greater than 6, it means that the number of keywords extracted according to the two historical records is still insufficient. At this time, the first extracting unit 302 needs to continue to extract keywords from the third history record until the total number of keywords that are extracted is greater than or equal to the first threshold and less than or equal to the second threshold. The conditions are up.

Further, the determining module 300 further includes:

The third extracting unit 304 is configured to: when the total number of extracted keywords is less than the preset number When a threshold is used, according to the massive vocabulary in the keyword determining mechanism, the keyword is continuously extracted, so that the total number of the extracted set of keywords is greater than or equal to the preset first threshold and less than or equal to the preset. Second threshold

The screening unit 305 is configured to: when the total number of extracted keywords is greater than a preset second threshold, filter keywords from the extracted keywords according to the keyword determining mechanism, so as to obtain a selected group The total number of keywords is greater than or equal to the preset first threshold and less than or equal to the preset second threshold.

If the total number of keywords extracted from the existing three history records is still less than the first threshold, the third extracting unit 304 may determine the mechanism according to the keyword, from the massive vocabulary of the keywords therein. The appropriate number of keywords is determined as a supplement; if the total number of extracted keywords is greater than the second threshold, the screening unit 305 may remove an appropriate number of keywords according to the keyword determining mechanism. It should be noted that among the extracted keywords, each keyword is different.

The first extraction module 400 is configured to extract the call key content from the recorded content of the call according to the determined set of keywords.

After extracting a set of keywords, the first extraction module 400 of the terminal gradually converts all or part of the recorded content of the call into text content, and then performs fuzzy matching on the obtained set of keywords with the text content. Or the meanings are similarly matched, so that the key content of the call of the call is extracted.
