A Fuzzy Logic Based Approach to Improve Cataloguing and Searching in e-Commerce Portals

A Recommender System Based on a Machine Learning Algorithm for B2C Portals

“…The similarity of a product e j ci to the o i specification is then calculated in two steps: 1) the normalised partial distance between e k ci and o i , according to a variable v j ci ∈ V ′ ci and denoted as d N (e k ci , o i , v j ci ), is obtained as described in [16]; 2) the partial distance values obtained in the previous step are aggregated to obtain the total distance value, as indicated in Eq. (1).…”

“…However, recommender systems based on fuzzy preferences have important usability issues when compared to the traditional lexicographic recommender systems [1]. These issues are consequence of the great amount of data that customers are required to input to the system when specifying a new search.…”

“…One of them is consumer-to-consumer (C2C) e-commerce, which refers to any business where the transactions are carried out by consumers who negotiate to try to reach an agreement [1]. One of the first C2C applications to appear was electronic auctions, which took advantage of the technological infrastructure offered by ecommerce to overcome the geographical constraints inherent to traditional auctions and have seen how the supply and demand is now approached from a global point of view.…”

Contribución al diseño y desarrollo de herramientas docentes basadas en TIC para entornos heterogéneos

“…En cada caso, las experiencias se centran en la potenciación o adquisición de habilidades muy específicas en los alumnos dependiendo, como es lógico, del alcance de cada actividad. En este sentido, la búsqueda de una metodología y secuenciación de actividades óptimas según los recursos disponibles o los entornos donde se lleven a cabo ha sido objeto de numerosos estudios teóricos (Castro-Schez, del Castillo, Hortolano & Rodriguez, 2009;Hoic-Bozic, Mornar & Boticki, 2009;Holbert, & Karady, 2009;Liu, Lin & Bhattacharya, 2008;Macías-Guarasa, Montero, San-Segundo, Araujo & Nieto-Taladriz, 2006;Mallinson & Nyawo, 2008;Shen, Wang, Gao, Novak & Tang, 2009). Además, muchos de estos estudios han propuesto incluso marcos de trabajo conceptuales que cubren desde el diseño y soporte tecnológico de estos sistemas hasta su implementación y consecuente evaluación de resultados de cara a maximizar los resultados educativos (Daradoumis, Martínez-Mones & Xhafa, 2006;Georgouli, Skalkidis & Guerreiro, 2008; Gomez-Sanchez, Bote-Lorenzo, Jorrin-Abellan, Vega-Gorgojo, Asensio-Perez & Dimitriadis, 2009;Hoic-Bozic et al, 2009;Konstantinidis, Tsiatsos & Pomportsis, 2009;Zurita & Nussbaum, 2007).…”
