DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
In order to solve the technical problem in the prior art that no communication content in the call process is saved in any form of text, an embodiment of the present invention proposes a display method and an electronic device, and the general idea of the solutions is as follow:
When two users are talking on the telephone, for example, when user A and user B are talking on the telephone, the communication content will be filtered by a series of rules in the electronic device, and the content identification, which can best characterize the communication content, can be selected and saved in the user's electronic device or the relay server (such as a third-party server). By using the electronic device, when browsing the call log, and in the meantime when acquiring a second ID identification of the other party, the content identification of the conversation between this electronic device and a second electronic device with the second ID identification is displayed to acquire the reminder of the last, or several previous, call content between the two users.
With reference to the accompanying figures, the main implementation principle, the specific implementation process, and the corresponding beneficial effects that can be achieved will be described in detail.
In a first embodiment of the present application, a display method is described. The method is mainly applied to a first electronic device, wherein the first electronic device includes a display unit and a communication unit.
Wherein, the first electronic device has a first ID identification, and the first ID identification is used for indicating a first user. The second electronic device has a second ID identification, and the second ID identification is used for indicating the second user.
Wherein, the first electronic device uses its communication unit to establish a communication connection between the first ID identification and the second ID identification with the communication unit of the second electronic device, so that the first user can communicate with the second user. The first electronic device records the call log of the first ID identification and the second ID identification.
In the above description, the first electronic device has many ID identifications, such as the SIM card number, QQ number, etc. When the ID identification is mainly the SIM card number, the first ID identification in the first electronic device is used to indicate the first user, which means that the first ID identification is the SIM card number representing the first user's identity.
The second electronic device is similar to the first electronic device, and the second ID identification of the second electronic device is used to indicate the second user, which means that the second ID identification is the SIM number representing the second user's identity. For example, 134XXXXXXXX represents Zhang San, or the corresponding contact of 134XXXXXXXX in the first electronic device is Zhang San. Therefore, in the embodiment of the present invention, when displaying the second ID identification, if the associated relationship with the contact has already been established, the name of the contact determined according to the second ID identification is displayed. If the associated relationship with the contact has not been established, the second ID identification itself is displayed.
The first electronic device uses its communication unit to establish a communication connection between the first ID identification and the second ID identification with the communication unit of the second electronic device, so that when the first user communicates with the second user, the first electronic device will record the call log between the two users. The call log is recorded in any form of text and is stored in the first electronic device or in a third-party server. The call log can be called when needed. FIG. 8 illustrates an example of a call log, as discussed above.
Specifically, when the first user and the second user are talking on the telephone, the process to convert the speech communication content of the two uses into the communication content recorded in the form of text will be described in detail in the following embodiment. The manner in which the first content identification and the second ID identification are displayed in the first electronic device will be described in detail.
As shown in FIG. 1, the method to display the first content identification and the second ID identification in the first electronic device specifically comprises:
At Step 101, a first display instruction is acquired.
At Step 102, in response to the first display instruction, the second ID identification is displayed on the display unit, and M first content identifications are displayed simultaneously.
Wherein, the first content identification is used for characterizing the communication content during the communication process of the first ID identification and the second ID identification, and M is a positive integer greater than or equal to one.
The method herein is to acquire the first user's speech stream and the second user's speech stream, respectively, after the two users have established a call connection, to convert the speech communication content into communication content in the form of text and to extract the first content identification from the communication content in the form of text. The first content identification is stored in the first electronic device or in a third-party server so that it can be displayed altogether, based on the first display instruction, when the first electronic device displays the second identification representing the second user.
For example, when user A (user A is the first user) uses the first electronic device to search for the call log of the call with user B (user B is the second user), the first electronic device is operated. At this time, on the first electronic device side, in the page of the call log, a number of ID identifications (not the first ID identification) will be displayed. Each of the ID identifications is used to indicate one user. The user calls the application/application program of the call log with an operation. The first electronic device obtains the operation of calling the call log through a sensor, performs the call operation, and displays the page corresponding to the application/application program of the call log. At this time, on the first electronic device side, when acquiring the first display instruction of performing the call operation and displaying the page corresponding to the application/application program of the call log, the content identification, corresponding to each ID identification, is displayed. That is, the content identification corresponding to each ID identification is displayed simultaneously when each ID identification is displayed. The second ID identification is displayed when calling, and the first content identification is displayed in association with it.
In another embodiment of the present invention, when the first electronic device displays multiple ID identifications in the page corresponding to the application/application program of the call log, the user performs specific operations on determined ID identifications according to his/her needs. The first electronic device additionally displays the content identification on the determined ID identification after it obtains the specific operation.
In yet another embodiment of the present invention, when the first user is talking to the second user on the telephone and after the first electronic device obtains the first user's specific operations through a sensor, the user performs extraction of content identification on the communication content of the call so that the first electronic device will display the content identification, correspondingly when the first electronic device displays the ID identification of the other party (the second user) of the call. In other words, if the extraction function of the content identification is not triggered during the call process, the first electronic device can only display the ID identification of the other party (the second user) when displaying the call log.
When the first electronic device stores the first content identification, there is a variety of ways. As described above, the first content identification can be stored in the first electronic device or a third party server. However, at this time, when the first content identification is stored in the first electronic device, it can be stored with the second ID identification, namely, in the same page. When the user views the second ID identification, the first content identification can be simultaneously displayed. Of course, when the first content identification is stored in the third-party server, it is directly displayed on the first electronic device by the address of the first content identification at the same time when the first electronic device displays the second ID identification. That is, the second ID identification is stored in the first electronic device locally, and the second ID identification is stored in the third party sever, both of which are displayed on the first electronic device simultaneously.
However, in the actual case, besides the synchronized display, when, for example, the second ID identification and the first content identification are stored in the call log but they are not displayed in the same page, the first content identification can be acquired by the following steps.
First, after the second ID identification is displayed on the display unit, the second display instruction is acquired.
Next, in response to the second display instruction, M first content identifications are displayed on the display unit.
Of course, the present application is not intended to limit the specific number of the first content identifications.
In addition to the above two cases, the first content identification can also be stored on a third-party server, and the display manner at this time is similar to that of the above second case. Namely, after the second ID identification is displayed on the display unit, the second display instruction is acquired, and then, the first content identification is extracted in the third party server and displayed.
The above method is the specific method for displaying the second identification and the first content identification, and the specific generation method is described in the following embodiment.
In a second embodiment of the present application, this embodiment is directed to the process of converting the speech communication content between user A and user B into communication content in the form of text. Secondly, how to extract the first contents identification from the communication content, after acquiring the communication content in the form of text for prompting the user, is described.
Wherein, there are two methods for the conversion manner.
The first one is as follow.
When user A and user B are talking on the telephone, the service provider is required to be involved. For example, the call or messages between user A and user B are supported by service providers (Telecom, China Unicom, and other network services). When user A and user B perform speech calls, video calls, and the like through QQ, the support of QQ services are needed. According to the embodiments of the present invention, the speech or video digital signals converted in the respective local devices of the two sides are directly identified and converted on the server side of the service provider. On the server side of the service provider, the communication content of the speech call or video call of user A and user B are identified and converted into text information. Thus, in the embodiment of the present invention, when user A and user B complete the speech call or video call, the text content is forwarded to the first electronic device of user A and the second electronic device of user B respectively. This facilitates the extraction of content identification by the first electronic device or the second electronic device. Further, according to the embodiments of the present invention, the content identification can be directly extracted and generated on the server side of the service provider. The server of the service provider stores the content identification or forwards it to the first electronic device so that it can be displayed altogether, when the first electronic device displays the identification of user B. In the embodiment of the present invention, the server of the service provider needs to have a speech recognition engine, and the local device (the first electronic device) does not need to be changed, thus the cost is low. Meanwhile, the server of the service provider is made up of multiple computing devices so the database is large, and thus, the effects of high speed and high accuracy of the recognition can be achieved.
The second one is as follow.
When user A and user B are talking on the telephone, the speech analog signals of the first user or user A, collected at the microphone of the first electronic device, are converted into speech digital signals by a conversion unit in sound card part. Then the speech digital signals are sent to the speech recognition engine (which can be either the speech recognition software installed in the first electronic device or the recognition engine used by the cloud). The speech digital signal of the second user or user B, received by the communication module of the first electronic device, is also sent to the speech recognition engine. Wherein, they are sent to the speech recognition engine according to the time sequence of the dialogue between the first user and the second user to ensure that the recognized and converted text is consistent with the communication content of the actual dialogue process. That is, the speech communication content is converted into the communication content in the form of text and stored in the first electronic device or a third-party server.
When the communication content recorded in the form of text is acquired, a first content identification will be acquired from the communication content, as shown in FIG. 2. The specific method is as follow.
At Step 201, N first content identifications are extracted from the communication content.
Where, N is a positive integer greater than or equal to one, and N is greater than M.
Regarding how to extract the N first content identifications from the communication content, the specific steps are shown in FIG. 3 as follows:
At Step 301, according to the preset rules of the electronic device, Q first content identifications are selected from the communication content.
Wherein, Q is a positive integer greater than or equal to one, and Q is greater than N.
For example, users A and B are on a call, the call content is as follows:
A: Hello, Mr. B.
B: Hello.
A: You have called me before. What is the matter?
B: Oh, you know, I am a patent attorney in XXX patent agency. I have an invention case No. 6265 of yours, and I am the attorney responsible for this case. I need to discuss with you about the technical solution. Do you have time now?
A: Yes, go ahead.
. . . .
B: Thanks for your help, bye.
A: Goodbye.
FIG. 9 illustrates an example of communication content with respect to the above-mentioned call between users A and B. The above dialogue is a dialogue about a patent, but there are also many identifications that are unrelated to the patent, such as “Hello”, “what”, etc. Therefore, firstly, rules will be pre-set in the electronic devices. For example, an identification vocabulary will be pre-set in the electronic device with a variety of less important identifications. According to the pre-set rules of the electronic device, the same words in the identification vocabulary will be deleted. Therefore, the following identifications will remain:
Patent, Occurrence: 3
Attorney, Occurrence: 2
Invention, Occurrence: 1
6265, Occurrence: 1
Technical solutions, Occurrence: 1
At Step 302, when Q first content identifications are selected, the weights of Q first content identifications are calculated.
After acquiring the above five identifications, the weight of each identification can be calculated.
In the embodiments of the present application, it can be calculated according to the formula

Wherein the meaning of each letter in the above formula is as follow:
i represents the first content identifier.
f(wi) is the respective weight of each first content identification.
Ai is the total number of times that the first content identification acts as the first content identification in the previous call log. As in the above example:
Patent: Occurrence 10
Attorney: Occurrence 5
Invention of: Occurrence 20
6265: Occurrence 10
Technical solutions: Occurrence 5
T is total number of times that user A communicates with user B, assuming T is five.

is the location impact weight of the first content identification in the communication content.

j is the individual occurrence times of the first content identification in the communication content.
N is the total occurrence times of the first content identification in the communication content.
aj is the impact ratio in the location when the first content identification occurs in different locations. The first content identification has different impact ratios in the communication content according to different locations. The ratio range is (0,1). For example, in the above embodiment, “patent” has different location impact ratios according to its different communication locations, namely, 0.5, 0.6, 0.7, respectively.
As can be seen from the above, the impact ratio can be arranged based on the order from front to back, that is, the more it is near the back of the communication content, the more important it is and the larger the impact ratio is.
In the actual content, the impact ratio is arranged based on the order from front to back or from back to front, which is not limited by the present application.
Lij is the impact ratio of the part of speech represented by the location when the first content identification is at different locations. For example, if the system identifies the first content identification as the subject and noun, the impact ratio is 0.8; if it is identified as the object and noun, the impact ratio is 0.7; if it is identified as the predicate and verb, the impact ratio is 0.3, etc.
For example, in the above example, the “patent” has different part of speech ratios according to the different parts of speech, namely: 0.5, 0.4, and 0.7.
In the actual case, the first content identification has different parts of speech when it is at different locations. When it has different parts of speech, it can be calculated according to

For example, in the embodiments of the present application, the impact weight of the location of “patent” is calculated in the communication content. According to the above statistics, “patent” appears three times in the communication content.
According to the above example, the following can be learnt:
The first time: position impact ratio 0.5, part of speech (POS) impact ratio 0.5.
The second time: position impact ratio 0.6, POS impact ratio 0.4.
The third time: position impact ratio 0.7, POS impact ratio 0.7.
Therefore, we can calculate the location impact weight of “patent” in the communication content, and it is 0.98.
According to the above similar algorithm, the respective position impact weights of the above first content identifications can be calculated:
Patent: position impact weight 0.98
Attorney: position impact weight 0.8
Invention: position impact weight 0.455
6265: position impact weight 0.7
Technical solutions: position impact weight 0.25
Bi is occurrence time of the first content identification in the communication content, and its meaning is consistent with N. Q is the number of the first content identifications selected from the communication content. In the embodiment of the present invention, Q=5.
According to the above formula, the respective weight of the first content identifications can be acquired:
Patent: weight 3.58
Attorney: weight 2.2
Invention: weight 4.655
6265: weight 2.9
Technical solutions: weight 1.45
In the embodiment of the present invention, the above listed formulas to calculate weights are merely intended to illustrate and explain the present application and are not intended to limit the application. The present application can use other formulas for calculating weights to calculate the above communication content. In addition, the present application can further optimize the weight of the first content identification acquired from the above formula based on the above-calculated weight, thereby acquiring a more accurate weight.
For example, when acquiring the weight of the above respective first content identifications, it can also be calculated according to the formula

Since the same content identification is not found in the communication content after “patent” has appeared for three times, the time interval here is considered to be the time interval after “patent” appears for the third time and before the last word in the communication content, namely, the second “bye”.
The speech energy value is acquired through analysis of the speech acquired in the system and comparison with the rules set in the system.
Thus, it can be calculated that the “patent” speech time energy feature is: 2.285.
According to these calculations, the following can be acquired:
Patent: speech time energy feature 2.285
Attorney: speech time energy feature 2.7
Invention: speech time energy feature 3.6
6265: speech time energy feature 3.5
Technical solutions: speech time energy feature 1
logminTi max Ei is the relationship feature between the maximum speech energy value and the minimum time interval in the first content identifications.
max Ei is the maximum speech energy value in the first content identifications.
min Ti is the minimum time interval value in the first content identifications.
By calculation, logminTi max Ei can be acquired to be 3.
Therefore, with the above calculation, the following weights after optimization can be acquired.
Patent: optimized Weight 8.865
Attorney: optimized weight 7.9
Invention: optimized weight 11.255
6265: optimized weight 9.4
Technical solutions: optimize weight 5.45
