Love, Language, and Linear Algebra: Linguistic Modeling of Personality and Mate Preference

This study utilized Latent Semantic Analysis to determine whether similarities in personality predicted similarities in responses to a romantic writing prompt (Landauer & Dumais, 1997). From participants’ writing samples, we calculated thematic cosines (a measure of relatedness) between each male and female participant. Participants also completed the Big Five Personality Questionnaire Short Form (Morizet, 2014). Extraversion, agreeableness, and conscientiousness were related to cosines, which suggested small-medium relationships from personality traits to written responses. This relationship was consistent with previous studies; therefore, Latent Semantic Analysis may be useful in quantifying mate preference, especially when alongside traditional survey methods. We conclude with a discussion of the compatibility of ordinal measures (survey data) and continuous measures in examining complex phenomena in the Behavioral Sciences

Plataforma software para análise textual de desordes mentais en Internet

[Resumo] A importancia dos métodos de prevención secundaria para os trastornos mentais é crucial xa que disto depende a calidade de vida futura das persoas que a sofren no presente. Os medios sociais poden favorecer un gran avance no desenvolvemento destes métodos debido a que son canles de comunicación nos que os usuarios e usuarias da Internet participan de forma activa e prevese que isto vaia aumentando co paso dos anos. O obxectivo principal deste proxecto é deseñar e implementar unha plataforma software que sirva de soporte aos especialistas da saúde mental, como psicólogos ou psiquiatras, para etiquetar aos suxeitos de maneira máis áxil, rápida e sinxela. A aplicación posibilitará a persoa usuaria procesar coleccións de documentos para ver as súas estadísticas, buscar documentos e realizar consultas a través delas. Tamén permitirá ao usuario ou usuaria analizar os resultados dos agrupamentos por similitude dos documentos ou termos que as conforman. Para poder alcanzar os obxectivos marcados eficientemente, decidiuse usar unha metodoloxía iterativa e incremental debido á flexibilidade e adaptación que aporta ás distintas situacións polas que un proxecto atravesa. Finalmente, conseguiuse unha plataforma software que cumpre cos requisitos especificados.[Abstract] Methods of secondary prevention for mental disorders are of crucial relevance because these depend the quality of future life of the people who are suffering mental diseases at the moment. Social media can improve develop these methods for the reason that it is a channel of communication where a lot of Internet users are involved and it is expected to increase over the years. The main goal of this project is to design and implement a software plataform to give support to mental health specialists, as psychologists or psychiatrists, to tag subjects agilely, quickly and easily. The application will allow the user process document collections to check their statistics, search documents and search queries in them. It will also allow the user to analyze the clustering results by similarity of the documents or terms that make them up. In order to achieve the goals set efficiently, it has been decided to use an iterative and incremental methodology for its flexibility and adaptation to the different situations that a project goes through. Eventually, it has been achieved an application that meets with the mentioned requirements.Traballo fin de grao (UDC.FIC). Enxeñaría informática. Curso 2019/202
