Abstract:
An educational institution (also referred as a university) is rich with multiple kinds of data: students, faculty members, departments, divisions, and at university level. Relating and correlating this data at and across various levels help in obtaining a perspective about the educational institution. A structural representation captures the essence of all of the relationships in a unified manner and an important aspect of the relationship is the so-called “influence factor.” This factor indicates influencing effect of an entity over another entity, wherein the entities are a part of the structural representation. A system and method for the construction of such a structural representation of an educational institution based on the educational institution specific information is discussed.

       FIELD OF THE INVENTION 
       [0002]    The present invention relates to the construction of a structural representation of a university in general, and more particularly, semi-automated construction of the structural representations. Still more particularly, the present invention relates to a system and method for semi-automatic construction of a model graph associated with a university. 
       BACKGROUND OF THE INVENTION 
       [0003]    An educational institution (also referred as university) comprises of a variety of entities: students, faculty members, departments, divisions, labs, libraries, special interest groups, etc. University portals provide information about the universities and act as a window to the external world. A typical portal of a university provides information related to (a) Goals, Objectives, Historical Information, and Significant Milestones, of the university; (b) Profile of the Labs, Departments, and Divisions; (c) Profile of the Faculty Members; (d) Significant Achievements; (e) Admission Procedures; (f) Information for Students; (g) Library; (h) On- and Off-Campus Facilities; (i) Research; (j) External Collaborations; (k) Information for Collaborators; (I) News and Events; (m) Alumni; and (n) Information Resources. In order to be able to assess the university in a manner for to be used for multiple purposes such as for prospective students, candidates exploring opportunities within the university, for the funding agencies, and for providing an objectivized assessment information for the university visitors, there is a need to construct a structural representation of the university based on the known information about the university. This constructed structural representation forms the basis for helping prospective students to have a better understanding of the university they are exploring to enroll and helping funding agencies to get a better picture of the university that they are planning to fund.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS 
       [0096]      FIG. 1  depicts an overview of UMG Construction System. The Universal Model Graph of an educational institution (or equivalently, a university) is a structural representation of the information about the educational institution and helps in the assessment of the educational institution at various levels. An important aspect of the assessment is the identification of the entities of interest of the educational institution. There are two kinds of entities: 
         [0097]    One, Entities that belong to operational and non-core activities (UDB); Primary source of information is the already existing operational database of EI; and 
         [0098]    Second, entities that belong to core activities (KDB); There are two sources for KDB: EI website and the web pages of people and systems part of EI. 
         [0099]    Perform Domain Analysis and discover as many entities as possible ( 100 ) and this results in the updated UDB and KDB ( 110 ). 
         [0100]    In the next step, Perform Entity Analysis; and Perform Pair-wise Entity analysis ( 120 ). 
         [0101]    Entity analysis leads to the identification of entity-specific models; There are three kinds of models: Parametric, Hierarchical, and Activity-based modeling; 
         [0102]    Pair-wise entity analysis leads to the identification of positive and negative influencers along with entity-specific perspectives. 
         [0103]    This leads to the updated databases ( 130 ). 
         [0104]    The major steps involved in the process of UMG construction are as follows ( 140 ): 
         [0105]    1. Perform Entity and Entity-Instance assessments based on Entity-specific and Entity-instance-specific models; 
         [0106]    2. Perform entity/entity-instance pair-wise mutual influences computations based on Models and Influencers; and 
         [0107]    3. Construct University Model Graph based on above two steps. 
         [0108]    An illustrative UMG is depicted in  150 . The nodes 1, 2, 3, and 4 are instances of STUDENT entity and the numerical value (&lt;1) indicates the entity-instance assessment. For example, the assessment of John Abraham is 0.74. Similarly, the other nodes also stand for entity instances: nodes 5 and 6 are instances of the entity FACULTY MEMBER while node 7 is an instance of entity LIBRARY. Note that if there is only one entity instance for an entity (say, LIBRARY), then the entity and the entity instance are used interchangeably. The directed edges (or equivalently, links) depict the nature and quantum of influences: for example, the directed edge (link) from node 5 to node 2 indicates a positive influence of 0.8 by the faculty member Alex McDermott on the student John Abraham. 
         [0109]      FIG. 1   a  depicts a partial list of entities of a University. Some of the critical entities include UNIVERSITY, FACULTY MEMBER, STUDENT, and LIBRARY ( 155 ). 
         [0110]      FIG. 1   b  depicts an illustrative University Model Graph.  160  describes UMG as consisting of two main components: Entity Graph ( 162 ) and Entity-Instance Graph ( 164 ). Entity graph consists of entities of the university as its nodes and an abstract edge ( 166 ) or abstract link is a directed edge that connects two entities of the entity graph. The weight associated with this abstract edge is the influence factor or influence value indicating nature and quantum of influence of the source entity on the destination entity. Similarly, the nodes in the entity-instance graph are the entity instances and the edge ( 168 ) or the link between two entity-instances is a directed edge and the weight associated with the edge indicates the nature and quantum of influence of the source entity-instance on the destination entity-instance. 
         [0111]      FIG. 1   c  provides a University Model Graph Construction Matrix.  175  showing the various elements of the matrix. The rows are labeled as Entity and Entity-Instance, and the columns are also similarly labeled. The element corresponding to Source Entity—Destination Entity indicates the influence factor or influence value (EI-Value) associated with Source Entity with respect to Destination Entity. That is, EI-Value indicates how a source entity influences a destination entity. Similarly, the element Source Entity-Instance—Destination Entity-Instance indicates the influence factor or value (I-Value) associated with Source Entity-Instance with respect to Destination Entity-Instance. That is, I-Value indicates how a source entity instance influences a destination entity instance. The element related to Entity-Instance and Entity indicates the influence factor or value (IEEI-Value) associated with the Source Entity-Instance with respect to Destination Entity. Finally, the element related to Entity and Entity-Instance indicates the influence factor or value (EIEI-Value) associated with the Source Entity with respect to Destination Entity-Instance. Further, these two elements also indicate the Entity assessment (E-Value) and the Entity-Instance assessment (IE-Value). Thus two assessments and four influence factors or values form the most significant ingredients of the university model graph. 
         [0112]      FIG. 1   d  provides the elements of a University Model Graph. The fundamental elements are nodes and edges. There are two kinds of nodes: Abstract nodes ( 180  and  182 ) and Nodes ( 184  and  186 ); There are three kinds of directed edges or links: Abstract links ( 188 ), links ( 190  and  192 ), and semi-abstract links ( 194  and  196 ). As part of the modeling, the abstract nodes are mapped onto entities and nodes are mapped onto the instances of the entities; an abstract link corresponds to an EI-Value, a semi-abstract link corresponds to either an EIEI-Value or an IEEI-Value, and finally, a link corresponds to an I-Value. Note that edges and links are used interchangeably. Further, each entity is associated with a model and an instance of an entity is associated with a base score and an instantiated model, wherein the base score is computed based on the associated instantiated model. 
         [0113]      FIG. 2  describes the notions of Entity Assessment. 
         [0114]    Notions of Entity Assessment ( 200 ): 
         [0115]    1. Entities are what a university or an Educational Institution comprises of; 
         [0116]    2. The assessment of the university at various levels depends on the assessment of individual entities; 
         [0117]    3. More particularly, a model is defined at entity and at various other levels; these models use the university database (UDB) and knowledgebase (KDB) to compute the assessment of the entity-instances; 
         [0118]    4. Entities are associated with models and the instances of the entities are associated with instantiated entity-specific models; 
         [0119]    5. Assessment of entity-instances is a numerical value between 0 and 1; The values close to 1 depict a better assessment of the entity-instance; Such a quantification helps in computing the assessment of a university at various levels; 
         [0120]    6. The assessment makes use of two distinct information sources: University Database (UDB) and University Knowledgebase (KDB); 
         [0121]    7. University Database—This is an internal operational database of a university and is updated based on the various transactions related to the entities; For example, UDB is updated based on transactions such as those related to (a) STUDENT admissions, (b) Grades of STUDENTs in tests and exams, and (c) EQUIPMENT procurement for a LABORATORY; 
         [0122]    8. University Knowledgebase—Some portion of the knowledgebase is internal to the university and some portion is meant for public consumption; For example, externally shareable information is what gets displayed in the university web portal; This knowledgebase is updated based on transactions such as (a) acceptance of a technical paper of a STUDENT along with a FACULTY MEMBER; (b) a technical seminar held at the university campus; and (c) granting of a fellowship to a FACULTY MEMBER. 
         [0123]      FIG. 2   a  describes the notations related to Entity Assessment.

Note that each parameter is associated with a data source that is used to compute the value for the parameter for any entity-instance using the associated parameter function PF. Finally, the parametric model function (PMF) combines these parameter values and in the illustrative model based on the weights associated with each of the parameters.

Further, each non-leaf entity is also associated with a set of parameters and based UDB and KDB, SP-Value is computed. The NLE-Value associated with FORM is based on SNLE-Value and SP-Value. This process is repeated and finally, the NLE-Value associated with the root entity is the assessment of the entity under consideration.

         [0282]      FIG. 7  describes the aspects of I-Value Computation. 
         [0283]    Aspects of and means for obtaining of information for I-Value Computation ( 700 ):
   1. Consider a pair of entity instances: IEi (of Entity Ei) and Iej (of Entity Ej);
       Iij ( 710 ) is the I-Value associated with the influence factor; That is, this indicates the quantification of the influence of Ei on Ej;   
       2. Factors affecting the I-Value computation:
       (a) Each entity Ei is associated with an assessment: assessments are at two levels: One, at Entity level and the second, at Entity-Instance level;
           These assessments are also called as base scores; These base scores change over a period of time leading to the change in I-Value;   
           (b) Consider the set transactions with respect to UDB and KDB over a period of time;
           The co-occurrence of IEi and IEj in the above set of transactions (LCOT) is another factor that affects I-Value computation; and   
           (c) The special attributes of IEi and IEj; These attributes are called as I-Params;   
       3. Double Time Series:
       (a) The Two time series ( 720  and  730 ) are related from the point of view of I-Value;
           The top time series ( 720 ) depicts the variation in base score or assessment of an entity instance IEi over a period of time;   The bottom time series ( 730 ) depicts the variation in the co-occurrence frequency between say, IEi and another entity instance, IEj;   
           (b) For the purposes of analysis, the timeline is divided into multiple segments and these segments could be any unit of interest, say, days, weeks, or months;

   4. In order to formalize further the aspects of I-Value computation, consider IEi influencing the entity instance IEj;
       (a) Positive Influencers (PIs) are defined with respect to a pair of entities, say, Ei and Ej; These PIs form part of a List of Positive Influencers (LoPI);   (b) Negative Influencers (Nis) are also defined with respect to the pair of entities; These Nis form part of a list of Negative Influencers (LoNI);   (c) A P-Perspective (PP) with respect to an entity, say, Ei (Ej), defines the extent of impact of positive influence of LoPI on Ei (Ej);   (d) Similarly, an N-Perspective (NP) with respect to an entity, say, Ei (Ej) defines the extent of impact of negative influence of LoNI on Ei (Ej);   (e) Generally, a perspective from an entity point of view provides a quantum of positiveness or negativeness;   (f) Consider a pair of entities: STUDENT and FACULTY MEMBER: Illustrative LoPI: Good grade obtained by STUDENT in a course offered by FACULTY MEMBER; A Good number of technical discussions between STUDENT and FACULTY MEMBER; and STUDENT is in top 10% in FACULTY MEMBER class; Illustrative LoNI: A low grade awarded to STUDENT by FACULTY MEMBER; and A poor attendance record of STUDENT in a class by FACULTY MEMBER;   (g) Consider PI: A Good Grade by STUDENT in a class by FACULTY MEMBER; STUDENT perspective: 0.7 while FACULTY MEMBER perspective: 0.2; A consistent performance results in a value of 0.6;   (h) Each PI associated with Ei and Ej has two perspectives: one associated with Ei and another associated with Ej; these two perspectives are a value between 0 and 1;   (i) Each NI associated with Ei and Ej has two perspectives: one associated with Ei and another associated with Ej; these two perspectives are a value between 0 and 1;   
       
 
         [0309]      760  summarizes the various aspects: I-Value ( 770 ) between a pair of entities Ei and Ej is mutual as depicted by a bi-directional arrow: that is, Ei influences Ej and Ej influences Ei; further, LoPI has two perspectives (PPi and PPj) and similarly, LoNI has two perspectives (PNi and PNj).

         [0378]      FIG. 8   c  provides an illustration of EI-Value, IEEI-Value, and EIEI-Value Computations. Consider two entities Ei and Ej;  830  describes the instances of Ei and  835  describes the instances of Ej; and the EI-Value is related to the influence of the entity Ei upon the entity Ej. This computation is based on the I-Values associated with the directed edge connecting  830  and  835  ( 840 ). Consider an instance of Ei; this influences multiple instances of Ej as depicted. The first step ( 845 ) is to reduce the I-Value associated with these multiple instances into a single value ( 850 ). At this stage, the computed single influence value is associated with the entity Ej as depicted. Note that this computed single influence value depicts the computation of IEEI-Value. This is repeated for each of the instances of Ei. Observe that multiple single values get associated with Ej. The next step ( 860 ) is to reduce these multiple single values to the EI-Value associated with the abstract link between Ei and Ej ( 870 ). In order to compute EIEI-Value, consider the multiple instances of Ej that influence an instance IEi of Ei ( 875 ). Reducing of the I-Vaues associated with these multiple instances into a single value results in the computation of EIEI-Value ( 880 ).

         [0420]      FIG. 9   g  provides an illustrative depiction of I-Value related to FM Instance. Note that I-Value is the weight associated with a link connecting two entity instances ( 970 ). Illustrated is the nature and quantum of influence by the faculty member Alex McDermott on the student John Abraham. 
         [0421]      FIG. 9   h  provides an illustrative computation of EI-Value, EI-Value, IEEI-Value, and EIEI-Value related to FM and S.  980  depicts illustrative instances of FACULTY MEMBER (about ten instances) and shows the instances of the entity STUDENT influenced by FM 1 (about twenty four of them). The figure also indicates the intermediate values leading to the computation of IEiEj-I-Value 0.28 (Single Value). 
         [0422]    Note that this forms the basis for the computation of IEEI-Value 0.13 between FM1 and S. The multiple single values with respect to the various of FACULTY MEMBER instances are analyzed to arrive at EI-Value (0.12). In order to compute EIEI-Value between STUDENT and FM1, fifteen instances of S influencing FM1 are considered. The resulting single value 0.11 forms the basis for the computation of EIEI-Value of 0.03 between STUDENT and FM1.

Finally,  996  depicts the I-Value of 0.811 between FM1 and S2. 
         [0425]      FIG. 10  provides an illustrative elaboration ( 1000 ) of University Modeling System. In a preferred embodiment, the University Modeling System ( 1020 ) is realized on a computer system ( 1005 ) with several processors, primary memory units, secondary memory units, and network interfaces, and with an operating system ( 1010 ) and a database system ( 1015 ). The database system in particular comprises of a component University Model Graph (UMG) DB Interface ( 1025 ) to help access University Model Graph (UMG) database ( 1030 ). As depicted in the figure, the University Modeling System comprises of two key components, namely, Model Construction ( 1035 ) and Transaction Analysis ( 1040 ). The Model Construction component is responsible for the construction of a university model graph associated with a university. More specifically, as an example, consider the University Model Graph predominantly modeling students: in this case, the nodes of the university model graph comprises of student assessments and directed edges denote the influence of students over other students. The Model Construction component helps compute both student assessments and student influence values. This component is assisted by the Transaction Analysis component that analyzes the student related transactions contained in UMG database and extracts the relevant information (as elaborated subsequently) for the model construction purposes. 
         [0426]    The IP Network Interface ( 1050 ) is used to connect the computer system to an Internet Protocol (IP) Network ( 1055 ) so that several users ( 1060 ) can connect and interact with the University Assessment System through the Internet or an intranet. 
         [0427]    Please note that, from the perspective of a set of students of a university, a structural representation of the university in the form of a university model graph is constructed by computing a set of assessments of the set of students and computing a set of influence values, and this set of influence values further comprises of a set of positive influence values between any pair of students, and a set of negative influence values between any pair of students of the university. 
         [0428]      FIG. 11  provides an illustrative set of attributes for Student assessment. The student assessment is based on a set of attributes ( 1100 ) and in particular, the set comprises of the following attributes: Test, Assignment, Exam, Attend, Focus, and Attention. These attributes are further described below. Test Attribute The percentage of marks scored by a student in a test (value between 0 and 1); this attribute captures the marks scored by the student in various tests. 
         [0429]    Assignment Attribute The percentage of marks scored by a student in an assignment (value between 0 and 1); this attribute captures the marks scored by the student in various assignments. 
         [0430]    Exam Attribute The percentage of marks scored by a student in an exam (value between 0 and 1); this attribute captures the marks scored by the student in the various exams. 
         [0431]    Attend Attribute: Student&#39;s actual class attend time with respect to the scheduled time and is a value between 0 and 1; this attribute captures the regularity of the student in attending the classes. 
         [0432]    Focus Attribute Student&#39;s focus indicator—a value between 0 and 1 provided by the class instructor; this attribute captures how focused the student had been while in the class; it is determined based on the student&#39;s postures while listening to the lecture. 
         [0433]    Attention Attribute: Student&#39;s attention indicator—a value between 0 and 1 provided by the class instructor; this attribute capture how attentive the student had been while in the class; it is determined based on unrelated activities performed by the student while listening to the lecture. 
         [0434]      FIG. 11A  provides an approach for computing student assessment. 
         [0435]    The student assessment computation is based on the data in the UMG database over an Analysis Period (AP). In particular, the various attribute data records such as those related to test attribute, assignment attribute, exam attribute, attend attribute, focus attribute, and attention attribute that are within AP window are extracted from the UMG database for assessment purposes. 
         [0436]    Obtain a student S of a university U ( 1101 ); Let AP denote the analysis period. 
         [0437]    Determine all data STest of S that are within AP and are related to Test attribute based on UMG DB ( 1102 ). 
         [0438]    Compute Test Factor (TF) of S based on STest ( 1104 ). 
         [0439]    Determine all data SAssignment of S that are within AP and are related to Assignment attribute based on UMG DB ( 1106 ). 
         [0440]    Compute Assignment Factor (AF) of S based on SAssignment ( 1108 ). 
         [0441]    Determine all data SExam of S that are within AP and are related to Exam attribute based on UMG DB ( 1109 ). 
         [0442]    Compute Exam Factor (EF) of S based on SExam ( 1110 ). 
         [0443]    Determine all data SAttend of S that are within AP and are related to Attend attribute based on UMG DB ( 1112 ). 
         [0444]    Compute Attend Factor (AdF) of S based on SAttend ( 1114 ). 
         [0445]    Determine all data SFocus of S that are within AP and are related to Focus attribute based on UMG DB ( 1116 ). 
         [0446]    Compute Focus Factor (FF) of S based on SFocus ( 1118 ). 
         [0447]    Determine all data SAttention of S that are within AP and are related to Attention attribute based on UMG DB ( 1120 ). 
         [0448]    Compute Attention Factor (AnF) of S based on SAttention ( 1122 ). 
         [0449]    Obtain weights W1, W2, W3, W4, W5, and W6 associated with Test, Assignment, Exam, Attend, Focus, Attention attributes ( 1124 ). 
         [0450]    Compute assessment of Student S as the weighted sum of the attributes ( 1126 ): 
         [0451]    W1*TF+W2*AF+W3*EF+W4*AdF+W5*FF+W6*AnF and this computed assessment is made part of the set of assessments. 
         [0452]      FIG. 11B  provides an approach for Test Factor computation. 
         [0453]    As described in  FIG. 11A , the student assessment involves the computation of various factors such as Test Factor, Assignment Factor, Exam Factor, Attend Factor, Focus Factor, and Attention Factor. Each of these factors is computed based on a set of data associated with the corresponding attribute. In the following, an approach for computing one of the factors, say Test Factor, is elaborated. 
         [0454]    Determine STest—a set of test marks of student S ( 1140 ). Note that this set is over a particular analysis period AP. 
         [0455]    Cluster STest to determine a set of clusters SC ( 1142 ). This step helps in computing a better value for Test Factor as, typically, the test marks can be widely distributed across the range. 
         [0456]    Rank the clusters in SC based on the size of clusters to result in ranked clusters RSC ( 1144 ). The objective of this step is to eliminate the so called the outliers. 
         [0457]    Let N be the size of STest ( 1146 ); Let Aplha be a pre-defined threshold; and let Beta be another pre-defined threshold. These thresholds are used to select the appropriate clusters for computing Test Factor. 
         [0458]    Select top-ranked clusters from RSC into TRSC such that size of each of the selected cluster is greater than or equal to N*Alpha ( 1148 ). 
         [0459]    Check whether such clusters can be found ( 1150 ). 
         [0460]    If it is not so, select a minimum of top-ranked clusters from RSC into TRSC such that sum of size of each of the selected clusters is greater than or equal to N*Beta ( 1152 ). This is the case when the test marks in STest are widely distributed and hence, there are no dominating clusters. 
         [0461]    Based on the clusters in TRSC, the weighted measure is computed as follows ( 1154 ): 
         [0462]    Let K be the number of clusters in TRSC; 
         [0463]    Let C1, C2, . . . Ck be the size of the clusters in TRSC; and 
         [0464]    Let N1 be C1+C2+ . . . Ck. 
         [0465]    Let M1, M2, . . . , Mk be the centroid of the K clusters in TRSC ( 1156 ). 
         [0466]    Computer Test Factor as (M1*C1/N1)+(M2*C2/N1)+ . . . +(Mk*Ck/Nk) ( 1158 ). 
         [0467]      FIG. 11C  depicts an illustrative data for assessment of students. 
         [0468]    The data for assessment of students is contained in UMG database and in particular, comprises of values for the various of the attributes such as Test, Assignment, Exam, Attend, Focus, and Attention ( 1170 ). 
         [0469]    Note that, for example, the values of the set STest is generated based on such data. 
         [0470]      FIG. 11D  provides illustrative test marks of a student. 
         [0471]    For example, STest for a particular student Smith comprises of normalized test marks obtained in the various tests ( 1174 ). 
         [0472]      FIG. 11E  depicts an illustrative set of clusters. 
         [0473]    STest depicted in  FIG. 11D  is analyzed to generate various clusters as per the flowchart depicted in  FIG. 11B  ( 1176 ). In particular, the value of N (the number of tests in STest) is 15 and Alpha, a pre-defined value, is set to 0.3. 
         [0474]    As depicted, four clusters get determined with sizes of 6, 5, 3, and 1. 
         [0475]      FIG. 11F  depicts the computed Test Factor of Smith. 
         [0476]    Based on Alpha, two clusters of sizes 6 and 5 become part of TRSC ( 1178 ). 
         [0477]    The value of N1 is 11 and the computed Test Factor of student Smith is 0.76. 
         [0478]      FIG. 12  provides an approach for computing influence value. 
         [0479]    The approach relies on the post transaction emotional pointers to determine the nature and quantum of influence. 
         [0480]    Read a transaction T from UMD Database ( 1200 ). A typical transaction could be sending of a text message by a student on a subject matter related to the university of the student to another student of the university. 
         [0481]    The transaction T is analyzed and the following sub-steps are performed ( 1205 ): 
         [0482]    1. Analyze transaction T to determine SourceActor (S2) and TargetActor (S1); 
         [0483]    2. If there are multiple source/target actors, consider the pair that is yet to be processed; 
         [0484]    3. In a typical transaction, S1 and S2 are students of the same university; 
         [0485]    4. Goal is to determine the impact (IP0) of an action of S2 on S1 due to the transaction T; 
         [0486]    5. Based on IP0, compute the Influence Value (PI21 for positive influence and NI21 for negative Influence) of student S2 on student S1. 
         [0487]    As a next step, the following sub-steps are performed ( 1210 ): 
         [0488]    1. Determine the post transaction EmotionData1 associated with SourceActor based on UMG database; 
         [0489]    2. As an example, such EmotionData1 can be an image of a face of SourceActor; 
         [0490]    3. Similarly, determine EmotionData2 associated with TargetActor based on UMG database. 
         [0491]    In the next step, the following sub-steps are performed ( 1215 ): 
         [0492]    1. Analyze EmotionData1 to determine EP1 as one of the emotional pointers; 
         [0493]    2. As an illustration, an emotional pointer can be Happy, Neutral, or Sad; 
         [0494]    3. Similarly, analyze EmotionData2 to determine EP2 as another emotional pointer; 
         [0495]    In other words, EP1 is one of {Happy, Neutral, Sad}; 
         [0496]    Similarly, EP2 is one of {Happy, Neutral, Sad}. 
         [0497]    Based on EP1 and EP2, determine the impact IP0 ( 1220 ). In a typical embodiment, a pre-defined table that maps the pair &lt;EP1, EP2&gt; to a value between −1 and +1 is used to determine IP0 (refer to  FIG. 12A ). 
         [0498]    Check if IP0 is less than 0 ( 1225 ). 
         [0499]    If not so, Obtain the last K positive impacts (PIP1, PIP2, . . . PIPk) ( 1230 ); Determine PI21 as the weighted average of IP0, PIP1, PIP2, . . . , PIPk; and the computed PI21 is made part of the set of positive influence values. 
         [0500]    If it is so ( 1225 ), Obtain the last K negative impacts (NIP1, NIP2, . . . NIPk) ( 1235 ); Determine NI21 as the weighted average of IP0, NIP1, NIP2, . . . , NIPk; and the computed NI21 is made part of the set of negative influence values. 
         [0501]      FIG. 12A  depicts an illustrative impact assessment. 
         [0502]    Observe that in one of impact assessment approaches, a pre-defined table that maps a pair of emotional pointers to a value between −1 and +1 gets used ( 1250 ). 
         [0503]    For example, if a source actor is Neutral (an emotional pointer, EP1) and a target actor is happy (an emotional pointer EP2), then it is concluded that the source actor impacts positively the target actor, and nature and quantum of impact is +0.50. 
         [0504]      FIG. 12B  provides an illustrative influence value computation. 
         [0505]    The scenario under consideration is a conversation between two students, Smith and John, in a university cafeteria ( 1260 ). 
         [0506]    As part of the conversation, John says something to Smith and this is an example of a typical transaction T. 
         [0507]    This transaction T is analyzed to determine SourceActor and TargetActor. 
         [0508]    Further, the emotion data post transaction T with respect to both John and Smith are obtained and analyzed. As depicted, it appears that John is Neutral (EP1) and Smith is Happy (EP2) post transaction T. 
         [0509]    Based EPI and EP2, the impact IP0 is computed using the Impact Table depicted in  FIG. 12A , and in this case, the impact is positive with a value of +0.50. 
         [0510]    In order to compute the positive influence of John upon Smith, the last K positive impact values are obtained from UMD database and note that each of these K positive impact values are from John to Smith. In the present case, K is set to 10. 
         [0511]    A weighted average is computed with the K weights as depicted and the positive influence value PI21 from John upon Smith is computed as +0.19. 
         [0512]    Thus, a system and method for the construction of a university model graph of a university is disclosed. Although the present invention has been described particularly with reference to the figures, it will be apparent to one of the ordinary skill in the art that the present invention may appear in any number of systems that construct influence based structural representation. It is further contemplated that many changes and modifications may be made by one of ordinary skill in the art without departing from the spirit and scope of the present invention.
