## Background
CROSS-REFERENCE TO RELATED APPLICATIONS
This application claims the benefit of Indian Patent Application Filing Number 2151/CHE/2014, filed on Apr. 29, 2014, which is hereby incorporated by reference in its entirety.
FIELD
The present disclosure relates generally to predicting human personality, and more particularly to system and method for predicting human personality using disc profiling and big five personality techniques.
BACKGROUND
Existing systems for personality trait prediction from text does the prediction separately for different sources of data like social media, call detail records, email. There are systems available that discloses multiple ways of performing personality prediction from text. The detection of different personality from text has been used widely across multiple fields, for example, one of the main areas, hiring process wherein personality prediction from text is currently used for determining

    
    
        Whether a personality is suitable for testing job, research manager, etc. . . . ?
        Whether he/she a good team player?
    
    


Personality prediction also helps to understand state of personality namely confused, organized, abstract or definitive. There are different techniques for predicting the personality from text. A person may typically have more than one personality trait but current systems are not able to identify which is the most prominent and less significant trait from the multiple personality traits identified.
The limitation of the current systems is how to correlate the information on the multiple personality traits that have been identified from the text from different sources of data. This limitation stems from the fact that the current systems do not go into deep levels like analysis of texts based on different topics and correlating them based on the prominent personality traits. Further, current systems do not know how to automate the above process in an efficient manner according to need and for benefit of different businesses.
Therefore, it would be desirable to have a system and a method for predicting the personality of the person by correlating the information obtained from different sources of data. Further, it would be desirable to have a mechanism for learning from user response to the predicted personality

FIG. 1 is a block diagram of a high-level architecture of an exemplary system 100 for predicting the personality of a human subject in accordance with the present disclosure comprising a data collection engine 102, a service layer 104, a storage engine 106, a segmentation engine 108, a personality prediction engine 110, a self-learning engine 112, and a person of interest engine 114. The data collection engine 102 collects data from external and internal sources. After collecting the data, the data collection engine 102 sends the data to the service layer 104. The service layer 104 further comprises a language identification module 116, a data filter and cleaning module 118, a rule based partitioning module 120, and a data transformation module 122 that processes the collected data. The processed data then goes to the storage engine 106. The processed data is accessed and it goes through further levels of segmentation and correlation by the segmentation engine 108. The segmentation engine 108 comprises a topic modeler 124 and a correlation module 126. After the segmentation of the data, the data is sent to the personality prediction engine 110 where personality prediction is made by a big five analyzer model 128 and a DISC profiler model 130. Then a scoring engine 132 gives score for a personality trait to a given topic. The person of interest module 114 performs people search based on personality traits, demographic distribution, gender and topic of interest related to a human subject. The person of interest module 114 comprises a search module 134, a pooling bench 136, and a ranking module 138.
The architecture shown in FIG. 1 may be implemented using one or more hardware processors (not shown), and a computer-readable medium storing instructions (not shown) configuring the one or more hardware processors; the one or more hardware processors and the computer-readable medium may also form part of the system 100.
FIG. 2 is a flowchart of an exemplary method for identifying a personality of a human subject in accordance with certain embodiments of the present disclosure that may be executed by the system 100 as described in further detail below. It is noted however, the functions and/or steps of FIG. 2 as implemented by system 100 may be provided by different architectures and/or implementations without departing from the scope of the present disclosure.
Referring to FIG. 2, at step 200, the data collection engine 102 may collect data from a plurality of sources. The plurality of sources may be external sources and internal sources. External sources may include social media and mobile data stores like Twitter, Facebook, blogs, forums, whatsApp etc. Call details records (CDR) may be another external source of data. In some embodiments, a new source may be added from a configuration file, for example, a new template can be added for social media listener. Internal sources may include gathering data from chat and emails.
Once the data may be collected by the data collection engine 102, the data may go to the service layer 104 that performs validation and filtration of the data (step 202). The validation and filtration of data has been illustrated by way of flowchart in FIG. 3. FIG. 3 illustrates an exemplary method of the validation and filtration of data in accordance with certain embodiments of the present disclosure. At step 300, language identification may be performed by the language identification module 116 by using some open source libraries designed for language identification. There are numerous such libraries and some of them are specialized for latin origin languages, some are for Indian languages and pictorial based languages.
At step 302, data cleaning and data filtration operation may be performed on the data by the data filter and cleaning module 118. The process of data cleaning may be a template based cleaning process as there are certain variation in data representation and format. For example; @ symbol has a different meaning in tweet as compared to @ symbol in email. Because of this; there may be a great need to have different type of filtration template. Also in terms of personality detection, use of certain characters has different meaning and represent different characteristic of any personality. Also in case of tweet, @ and # has got special meaning where as it may not necessarily true for blog and new sites. Based on the source of data, special characters from the text may be removed. So we will have customized filter based on the source of data. The process of data filtration may be done by using machine learning based classifier which is trained based on how we define business and non-business data. For example; if this engine may be used to know whether a user is an influential personality of a particular brand; then all the data which doesn't belong to that brand and competitor brand may be removed in analysis.
At step 304, the data may undergo through rule based segmentation. There may be a great impact of demography, culture/society and gender to some extent in building the personality of a person. For gender detection, if the source of data is email then gender detection may be straight forward as the email server contains user profile with full name, address, gender, etc. but for the cases when it is not known, a gender detection dictionary/algorithm based on name may be used.
At step 306, all the preprocessed data may be made ready in the format (either document/column based) to be loaded into the storage engine 106 which acts as data store with additional detected information in this step (like demography, gender, etc. . . . ). The storage engine 106 may work as the repository store of all the collected and processed data both at intermediate and final state.
For optimization and faster access, the storage engine 106 may be designed as a hybrid store of both SQL and No-SQL based databases. SQL may work as meta store of data for faster access and No-SQL may work as document store of all the collected and processed data.
At step 204, the data stored in the storage engine 106 may be accessed and may go through segmentation comprising clustering and then correlation. It may be found out what all are the topic on which the processed data may be talking about. It may comprise of an advanced feature of configuring profiles and demographics, and building multiple hierarchical clusters of similar topics. For example, there may be clusters based on i-pad, i-phone. Clustering of the processed data may be performed by the topic modeler 124.
Every human may pose different types of personality based on his/her knowledge in particular section/area. A person who is more into say automobile may understand it better and might poses a character of being more careful in terms of car servicing, which is a sign of “Conscientiousness” characteristics as per Big Five model. There could also be a case where a person talks a lot about cars and is in day in and out into it, but is not very careful about it, which gives the degree of conscientiousness characteristics. Thus, there is a great need to know the characteristics possessed by an individual in a particular category. A person with less degree of conscientiousness in automobile is more likely take less care of his/her car and might run into too many insurance claims. It also helps to know whether an individual is Influential among community about car which opens new door for automobile providers to make him/her as the brand ambassador on say twitter and expand business. The Topic Modeler 124 internally uses topic modeling algorithms and build clusters around multiple topics of interest of an individual.
Thereafter the correlation engine 126 may find relationship between multiple people based on topic of interest, physiographic distribution, gender difference and demographic distribution. This correlation engine 126 may create a collaborative filter matrix of all the people whose interest are of similar kind, lives in same region, share the same gender and have the same personality traits. The collaborative filter matrix may be stored in the storage engine 106. The correlation engine 126 may help the person of interest module 114 to search similar kind of people better. So let us say we are looking for a person who is influential in nature and lives in say West Coast and is male, then this system will quickly refer to the collaborative filter matrix been built by the correlation engine 126 and will pass on the result of person of interest module 114. This may optimize the search.
At step 206, personality prediction may be performed. The personality prediction has been illustrated by way of flowchart in FIG. 4. FIG. 4 illustrates an exemplary method of the personality prediction using DISC profiling and the big five techniques in accordance with certain embodiments of the present disclosure. The personality prediction may be done without having any question and answer kind of session with the user. The personality prediction engine 110 may generate knowledge like what is the personality trait of human subject in different section of topic. It is highly possible that a human subject possess steadiness in personality in some topic, but could be dominating in some other section. The friend circle analysis is also done in this section to know more about the person and also the profiling of friends is done to know what kind of circle he/she is in. This will help to fill in hidden gaps while predicting personality traits.
Big Five Analyzer model 128—At step 400, the text posted by the human subject in particular topic is analyzed using the Big Five factors (Openness, Conscientiousness, Extraversion, Agreeableness, and Neuroticism). This model is used to find out the high level trait possessed by the human subject by analyzing the text posted on a topic. This model 128 is used to find out whether:

    
    
        The person is open to new experience/solutions. While building up personality traits, it will be checked whether the topic extracted is about some new products or not. If it is relatively new product and then the users are trying to explore new features into it, then it is considered as sign of a quality of been open to new experience.
        The person is conscientious about the certain topic.
        The person is also very excited about certain topic and loves to talk a lot about it.
        The person agrees to other people's view or only tries to put his/her ideas on top of others.
        The person is very sensitive to certain things and expresses his/her emotion in some form.
    
    


DISC Profiler model 130—At step 402, in the DISC Profiler model 130, the DISC (Dominance, Inducement, Submission, and Compliance) traits are used for analyzing the data. This model 130 is used to find out the granular level personality traits possessed by the human subject. From the text posted by the user on a particular topic across different social media, mobile apps, CDR and emails, there are always certain patterns possessed by person based on whatever quadrant of DISC he/she belongs to. For example, the person with Dominance characteristics will always try to talk about oneself with addition pattern stating that he/she is not satisfied by the people around him/her. So from the text the Profiler module will extract information on how many times the user talks about oneself and how frequently he/she points out problems as compared to talking good things about it. This may be used to decide whether a person is of D characteristics then what is the percentage of it. Similarly; the person with Compliance characteristics will tend to find out small-small things out of the information. She/he may deep dive in a particular topic and will basically point out problems. The DISC profiler module 130 may be the rules that will be used for identifying the traits possessed by different kind of personality. The rules would be run on the user data information to build DISC personality profile by this model.
At step 404, the scoring engine 132 gives scores for the personality trait to a given topic. A person might be highly attached to certain topic whereas least bothered about some of the other things. Based on the total data set talking about personality trait on a particular topic, the scoring engine 132 may use certain/specific emotion attached to it and then gives score to the personality trait. The emotion detection may be done by using a technique of how frequently the person talks about a certain topic and what is the sentiment associated to it. The sentiment detection may be done using contextual based linguistic algorithms. For e.g. if the person possess a quality of openness to experience to certain topic as per big five analyzer model 128, then it is determined to what percentage he/she is open to experience new things. Every person has some percentage of personality traits from all different dimensions/quadrants of DISC profiler model 130. This scoring engine 132 may build the scoring of the personality trait like, if a person is dominating in nature then what is the percentage of that quality and so on.
Referring to FIG. 2, at step 208, predictions are rendered by ranking done based on multi-correlation approach. User performs an advance personality based search using the search module 134 in the Person of Interest module 114. The search is performed based on linguistic based search which is done on the personality traits and score identified in Step 206 and available in the storage engine 106. The user can also do the search for the right kind of personality in an organized way using the configurations details provided in the pooling bench 136. After the search is performed by the searching module 134 and it is provided to the ranking module 138 before rendering the search results to the user. The ranking module 138 does the ordering of the search results by using a personality trait based ranking algorithm and also determines confidence level by marking some of the result with in the scale of 1-5 distinguished by color codes like green, yellow, red etc.
At step 210, user response to prediction is monitored and studied using the self-learning techniques. When the user does a search using the person of interest module 114, the self-learning engine 112 learns from the user response to the search result. The self-learning engine 112 monitors and studies the pattern in which the user accesses the search results. That is the self-learning engine 112 learns from the user ‘clicks’ on search page and stores the feedback as for what all topics, profiles, demography and gender the system is not giving the optimum result. The self-learning Engine 112 then normalizes the score associated with the personality trait to optimize the predictions based on the user response. After this the normalized score is stored back to the Storage Engine.

10. The method of claim 1, wherein the second model is big five model (openness, conscientiousness, extraversion, agreeableness, and neuroticism).

11. A system for predicting a personality of at least one human subject, the system comprising:
one or more hardware processors; and
a computer-readable medium storing instructions that, when executed by the one or more hardware processors, cause the one or more hardware processors to perform operations comprising:
receiving data associated with the at least one human subject from one or more sources;
clustering the data based on one or more topics of interest of the at least one human subject using one or more topic modeling algorithms;
predicting at least one high level personality trait associated with the at least one human subject by analyzing the clustered data, the at least one high level personality trait being one of the one or more high level personality traits defined by a first model; and
predicting at least one personality profile by classifying the at least one high level personality trait into one or more granular level personality traits defined by a second model, the classifying being based on clustered data.

12. The system of claim 11, wherein a score is assigned to each of the one or more granular level personality traits based on emotion attached to the at least one topic of interest.

13. The system of claim 12, wherein the emotion attached to the at least one topic of interest is determined based on frequency of talking about the at least one topic of interest by the at least one human subject across the one or more sources.

14. The system of claim 12, wherein receiving the data associated with the at least one human subject from the one or more sources comprises:
retrieving the data from the one or more sources;
performing language identification on the data;
cleaning and filtering the data by removing unwanted characters and notation;
partitioning the data based on demography, culture, and gender; and
transforming the data to at least one format.

15. The system of claim 11, wherein a people search is performed based on at least one of a high level personality trait, the at least one personality profile, demographic distribution, gender, and the at least one topic of interest.

16. The system of claim 15, wherein a confidence level is determined for result associated with the people search, the confidence level indicative of accuracy of the result.

17. The system of claim 11, wherein a multi-dimensional hierarchical correlation matrix of one or more human subjects of the at least one human subject is generated based on at least one of the one or more topics of interest, gender, and demography.

18. The system of claim 11, wherein response of a user to the predicted at least one high level personality trait and the predicted at least one personality profile is monitored using self-learning techniques.

19. A non-transitory computer-readable medium storing instructions for predicting a personality of at least one human subject that, when executed by a processor, cause the processor to perform operations comprising:
receiving data associated with the at least one human subject from one or more sources;
clustering the data based on one or more topics of interest of the at least one human subject using one or more topic modeling algorithms;
predicting at least one high level personality trait associated with the at least one human subject by analyzing the clustered data, the at least one high level personality trait being one of the one or more high level personality traits defined by a first model; and
predicting at least one personality profile by classifying the at least one high level personality trait into one or more granular level personality traits defined by a second model, the classifying being based on clustered data.

20. The non-transitory computer-readable medium of claim 19, wherein a score is assigned to each of the one or more granular level personality traits based on emotion attached to the at least one topic of interest.
