10. Incorporación de funcionalidades en una herramienta de análisis de sentimientos en mensajes de twitter mediante lexicones

Author

Jiménez Martín, Antonio, Moreno Jiménez, José María, Alés Herranz, Diego, Jiménez Martín, Antonio, Moreno Jiménez, José María, and Alés Herranz, Diego

Abstract

Este trabajo Fin de Grado (TFG) se centra en la incorporación de nuevas funcionalidades a una herramienta de análisis de sentimientos basada en el uso de lexicones en español a partir de las publicaciones de los usuarios en la red social Twitter. El objetivo fundamental del mismo es el estudio de la herramienta en su estado actual, la investigación acerca de las distintas librerías y herramientas externas que se iban a utilizar para la incorporación de las nuevas funcionalidades, y la clasificación de las nuevas utilidades que se busca implementar, atendiendo al nivel de importancia de las mismas. La herramienta está implementada de forma íntegra en Python, empleando librerías externas para la realización de la interfaz, la conexión con la base de datos, etc. con el fin de realizar de manera automática y eficiente el análisis de sentimientos. Estas funcionalidades extra que se añaden a la herramienta incluye el estudio del método de análisis de sentimientos mediante lexicones, así como los distintos lexicones que existen en español, el estudio de la herramienta Gephi para su conexión con nuestra herramienta, la incorporación de hitos en la salida del estudio de los sentimientos, de forma que se pueda saber si una tendencia de sentimientos corresponde a un hecho concreto y la incorporación de nuevas visualizaciones de gráficas, como el uso de la media móvil para el suavizado de las curvas gráficas, permitiendo su mejor visualización. Para ello, lo primero que se ha hecho es un proceso de investigación y análisis del estado de arte de los distintos métodos de análisis de sentimientos que existen en el mercado, pudiendo distinguir en qué casos resulta más beneficioso utilizar uno u otro, así como del caso concreto del análisis de sentimientos mediante el uso de lexicones. Finalmente se profundizó en todo lo que se había desarrollado sobre la herramienta, y cuál era su estado actual, pues al partir de un Trabajo de Fin de Máster (TFM) y habiendo continuado su desarrollo

13. Multicriteria evaluation of technological competitiveness in diversification processes. An application to the automotive components industry.

Abstract

Considering technological competitiveness in diversification processes as the existence of key technologies that guarantee the current and future effective running of firms in terms of their technological and operational potential, this paper presents a multicriteria approach for its evaluation and provides an index for measuring the technological competitiveness of diversification processes. The application of this multicriteria approach, based on the analytic hierarchy process, in three real technological diversification processes allows (i) the validation of the hierarchical model (five levels and 25 attributes) and the index (73 indicators) proposed for evaluating the technological competitiveness; (ii) the use of this hierarchical model and index to confirm the suitability of the diversification process and to extract knowledge related to the technological and operational potential of the firm; and (iii) the exploitation of this knowledge in order to guarantee the long‐term survival of automotive components industry's firms. The methodology finds the most relevant attributes in the automotive component sector (innovative capacity and activity, good functioning of the management and finance departments). Its practical application determines the firm's suitability for a diversification process, identifies the attributes that require some improvement, and the decision opportunities. After 5 years, the three companies that have been studied showed a behaviour aligned with the values and recommendations of the index developed to assess technological competitiveness. The main limitation lies in the difficulty of studying companies if they change or disappear in the future. [ABSTRACT FROM AUTHOR]

16. A Decision Support System for Improving the Inconsistency in AHP.

Author

Escobar, María Teresa, Aguarón, Juan, Moreno-Jiménez, José María, and Turón, Alberto

Abstract

This paper presents a DSS aimed at helping decision makers reduce and improve their inconsistency in eliciting their judgements when using the analytic hierarchy process (AHP). The DSS is designed for revising the judgements of a pairwise comparison matrix when the row geometric mean (RGM) is used as the prioritisation procedure and the geometric consistency index (GCI) as the inconsistency measure. The procedure employed guarantees that both the judgements and the derived priority vector will be close to the initial values. The DSS allows different degrees of participation of the decision maker in the review/modification of the judgements: no participation (automatic mode); prior participation (semi-automatic mode); and ongoing participation (interactive mode). The DSS also includes options to incorporate other requirements of the decision maker, such as limiting the modified values to an interval or improving inconsistency by modifying the lowest number of judgements, among others.

33. Conflict resolution in the era of cognitive multicriteria decision‐making: an AHP‐retributive approach.

Vargas, Luis G., Moreno‐Loscertales, Cristina, and Moreno‐Jiménez, José María

Abstract

This paper puts forth the foundation for a different type of negotiation that reflects in a more realistic way the behavior of human beings when making complex decisions, aligned with the cognitive process involved. The positive and the negative aspects of decisions reflect two components in the human brain: the nucleus accumbens and the amygdala. The first component deals with behavior related to rewards or potential gains, and the other with behavior related to risk aversion or potential losses. Negotiations require communication, learning, accommodation of positions, and development of alternatives and modification of constraints. Negotiation support systems help and advice negotiators; structure and analyze the problem; elicit preferences to construct a preference function; visualize different aspects of the problem and the process; and facilitate communication and learning. The methodology used is based on the Analytic Hierarchy Process previously employed in a retributive conflict in which each party calculates the incremental benefits it gets and the costs to its opponent. The Israeli–Palestinian conflict is used to show the viability of the approach and the type of inputs we need to study conflicts with this approach. The negotiation platform that we describe here help the actors to start and engage a negotiation from noncooperative parties. It can also be used in human– negotiations to expedite reaching an agreement if one exists. However, we are not seeking automated negotiations. Advantages and risks of Artificial Intelligence contribution in negotiation support systems for cognitive and retributive conflict resolution based on AHP (CRCR‐AHP) are also discussed.

Abstract

The International Transactions in Operational Research has issued a call for papers for a special issue on "Decision Support Systems in an uncertain world." Decision Support Systems (DSS) are tools designed to assist policy makers and others in making complex decisions that consider the objectives of multiple stakeholders and are robust under different circumstances. The special issue welcomes articles on methodologies, technologies, and application-oriented works addressing decision support challenges. The deadline for submissions is February 29, 2024, and the papers will be peer-reviewed according to the editorial policy of the journal. The call for papers is open to the entire academic and practitioner community. [Extracted from the article]
