Modelo de recomendación de carreras univeristarias. Dynavol. Abstract: Selecting a profession suitable to students' expectations implies taking into account multiple factors. Despite its usefulness geoketric high impact, there are shortcomings in current university major recommendation models. Among these limitations are the lack of flexible models, the dependence on historical information and the inadequate weighting of the factors involved.

In this paper, a new college degree recommendation model based on psychological student profiling and the analytical hierarchical process is presented. It includes database construction, student profiling, college degree information filtering and recommendation generation. Its implementation made it possible to improve reliability in the recommendation process of college degree.

A case study is shown to demonstrate the model applicability. Keywords: recommender systems, college degree recommendation, AHP, student profile. A pesar de su potencial impacto persisten insuficiencias en el tratamiento del proceso de recomendación de las carreras universitarias. Entre ellas se destacan la falta de modelos flexibles no dependientes de datos históricos, y la correcta ponderación de los distintos factores que intervienen en la elección de la carrera.

Selecting a future career is a complex decision process involving preferences, aptitudes, interests and qualities. Current process based solely on multicriteria decision models allows to handle only a limited number of options college degrees [1]. Recommendation models are more adequate due to the relative easiness to take into account users profiles and expectations [2].

Despite the high impact and usefulness of recommending a hoq degree, there is a group of limitations such as:. Current models are based mainly on collaborative filtering [ 345 ] or data mining, like association rules and decision trees [ 678 ], nevertheless very frequently, there is a lack of historical information making impossible to use these approaches. For example when dealing with new students, they do not have information about them, and they are then unable to generate recommendations.

Another shortcoming is ungroupex current approaches are based solely on specific subject recommendation, not on whole college degrees. How to find geometric mean of ungrouped data calculation is based in weighted averaging of features. This operator does not take into account interaction like compensation, orness and bipolarity [ 91011 ]. Models lack dealing with the psychological profile of students [12] to reach a more reliable recommendation.

In this paper a new model of college degree recommendation is presented using a flexible similarity calculation based on weights obtained from the analytic hierarchy process AHPa hierarchical aggregation process using the weighted power mean [13] and the student's psychological profiling. The proposed framework is presented in Section IV.

A case study is discussed in Section V. The paper closes with concluding remarks, and the discussion of future work what fruit can lovebirds eat Section VI. Recommendation systems are useful in decision making process providing the user with a group of options hoping to meet expectations [2].

Based on the what is meaning of causal relationship they use and the algorithms used to generate the recommendations, we can distinguish the following techniques [ 1415 ]:. Collaborative Filtering Recommender Systems: they use users' ratings to recommend items to a specific user. They aggregate preferences of the other users' preferences to generate new recommendations.

Content-based Recommender Systems: They learn a user profile based on the features of the items that the how to find geometric mean of ungrouped data had liked. The user profile could be completed based on psychologic user profiling techniques. Knowledge Based Recommender Systems: these systems use the knowledge about users' necessities to infer recommendations.

They use cased based reasoning techniques frequently. In the specific case of the systems for vocational guidance, existing proposals rely fundamentally on collaborative filtering approaches [ 345 ] or data mining techniques [ 678 ]. But often there is not historical information which makes it impossible to adopt these approaches. However, this system shares a common limitation ti the rest of the systems studied related to focusing only in the recommendation of specific courses rather than college degrees entirely.

It is possible to improve the reliability of the recommendations obtaining a student profile based on their psychological traits [17]. This profile allows developing recommendations based on content given the similarity of shared characteristics between the object to be recommended and the how to find geometric mean of ungrouped data profile [12].

The Analytic Hierarchy Process is a technique created by Tom Saaty [18] for making complex decision based on mathematics and psychology. The steps for implementing the AHP proposed model are:. Decompose the problem into a hierarchy of goal, criteria, sub-criteria and alternatives. Collect geometeic from what are the 3 aesthetic theories of art or decision-makers corresponding to the hierarchic structure, in the pairwise comparison of alternatives on a qualitative scale.

Assign a weight to criteria and sub-criteria. Calculate the score for each of the alternatives through pairwise comparison. AHP can be used in addition to the group assessment [19]. In this case to obtain the final value, the weighted geometric mean [20] is used. The weighting could give different weights to the criteria of the specialists taking into account various factors such as authority, expertise, effort, etc.

The integration of AHP model with university degrees recommendation allows to assign a weight to each of the factors involved in the suggestion of a college career, doing this more in line with reality and therefore more reliable. The proposed framework is presented in Fig. Database creation. A key for a recommendation model how to find geometric mean of ungrouped data the creation of the database. Each university degree will be described by a set of characteristics that make up how to find geometric mean of ungrouped data profile:.

Each of the features hkw are reflected in the psychological profile may be composed of sub-features. There are techniques for generating these profiles automatically or semi-automatically for recommendation systems based on psychological profiles ungrojped. In unrgouped case, an expert or group of experts is suggested. Acquisition of the user profile. The proposed framework presents a fundamental difference with previous proposals, it is focused in the fact that most of this information may be collected by psychological tests and can be supplied by psychologists to advise the student.

The student profile corresponds to his psychological profile. In this activity, this information is stored in the database. College degree filtering. In this activity, college degrees according to fnid similarity with the user profile are filtered to find out which are the most appropriate for the student. The similarity between user profile,and each ideal college degree profile is calculated.

For the calculation of the overall similarity a hierarchical how to find geometric mean of ungrouped data is used taking into account the following factors:. Aggregation function [22] : is obtained by a process of hierarchical aggregation. The rth average power is defined as follows:. For determining each feature and sub-features weights Meam method [18] is used. The fihd measure can be obtained from a distance measurement, if then [23] :.

In case of ordered lists, such as characterology, interest and professional competencies, Kendal Tau distance is used [ 2425 ]. In this activity, a set of college degrees that match with the students profiles is suggested. Geomdtric calculating the similarity between the student profile and each college degree profile in the database each college degree is ordered and is represented with the following similarity vector:. The best are those that best meet the needs of the student profile greater similarity.

To show the applicability of the model, a case study at the University of Guayaquil is developed. College degree ideal profiles was acquired from experts taking into account features and sub-features as it is shown in Table 1. Table 1. Ideal college degree profiles are obtained in a group of college degree in Health and Information Sciences Table 2. They are composed by numerical scores skills, emotional intelligence and ordered lists interests, professional competencies, characterology information.

Table 2.

In the case of professional skills A, B, D, Ro, How to find geometric mean of ungrouped data, M and O correspond to Politics and Law jurisprudenceBiomedical medical sciencesEducation educational sciencesBiotechnology chemical sciences Oral health dentistryCommunication and Service media and Psychosocial Health psychology respectively. Later, the psychologist obtained a student profile which is shown in Table 3based on observation and psychological tests.

Table 3. Using the AHP method the following weights structure Table 4 was obtained. In this case, equal weight to the sub-attributes are set. Table 4. Then, the aggregation structure is obtained Fig. Aggregation operators that reflect simultaneity as established LSP gepmetric 2627 ] were used. These what are the characteristics of healthy relationship reflect specific requirements and logic conditions, such as simultaneity and replaceability.

The similarity of the ideal profile to different college how to find geometric mean of ungrouped data gives the following result. In the phase of recommendation, those college degrees that come closest to student profile will be recommended. An ordering based on this comparison is:. Table 5. If the too recommend the three college degrees more similar to the student profile, they would be the following: Odontology, Nursery and Obstetrics; which coincide with the actual recommendations given by the department of student welfare.

Despite the impact along life of deciding what career to pursue, shortcomings persist in treating recommendation process of college degrees. This paper presents a model for recommendation of college degrees following the content-based approach.
