Performing Hybrid Recommendation in Intermodal Transportation – the FTMarket System’s Recommendation Module

Diverse recommendation techniques have been already proposed and encapsulated into several e-business applications, aiming to perform a more accurate evaluation of the existing information and accordingly augment the assistance provided to the users involved. This paper reports on the development and integration of a recommendation module in an agent-based transportation transactions management system. The module is built according to a novel hybrid recommendation technique, which combines the advantages of collaborative filtering and knowledge-based approaches. The proposed technique and supporting module assist customers in considering in detail alternative transportation transactions that satisfy their requests, as well as in evaluating completed transactions. The related services are invoked through a software agent that constructs the appropriate knowledge rules and performs a synthesis of the recommendation policy

AN AGENT-MEDIATED MARKETPLACE FOR TRANSPORTATION TRANSACTIONS

Abstract. This paper reports on the development of an innovative agent-mediated electronic marketplace, which is able to efficiently handle transportation transactions of various types. Software agents of the proposed system represent and act for any user involved in a transportation scenario, while they cooperate and get the related information in real-time mode. Our overall approach aims at the development of a flexible framework that achieves efficient communication among all parties involved, constructs the possible alternative solutions and performs the required decision-making. The system is able to handle the complexity that is inherent in such environments, which is mainly due to the frequent need of finding a modular ” transportation solution, that is one that fragments the itinerary requested to a set of sub-routes that may involve different transportation means (trains, trucks, ships, airplanes, etc.). The system’s agents cooperate upon well-specified business models, thus being able to manage all the necessary freighting and fleet scheduling processes in wide-area transportation networks. Keywords. Software Agents, E-Marketplace, Transportation Management. 1

Cardiovascular risk factors in HIV infected individuals: Comparison with general adult control population in Greece

Background Although combined antiretroviral therapy has substantially improved the prognosis of people living with HIV (PLHIV), mortality remains higher compared to the general population, mainly due to higher prevalence of non-HIV-related comorbidities, including cardiovascular diseases (CVD). We assessed the prevalence of CVD risk and its contributing factors in adult PLHIV versus general population controls in Greece. Settings Cross-sectional comparison of PLHIV (Athens-Multicenter-AIDS-Cohort-Study; AMACS) versus general population controls (National health examination survey; EMENO). Methods All HIV-infected adults with ≥1 measurement of interest (blood pressure, lipids, glucose, weight, height) between 2012-2014 and all EMENO participants (2014-2016) were included. Ten-year total CVD risk was estimated using the Framingham (FRS) or the Systematic Coronary Risk Evaluation (SCORE) equations. Results 5839 PLHIV (median age:41.6 years, 85.4% males) and 4820 controls (median age:48 years, 48.4% males) were included. Adjusting for age, sex and origin, PLHIV were more likely to be current smokers (adjusted OR:1.53 [95% CI:1.35-1.74]) and dyslipidemic (aOR:1.18; [1.04-1.34]), less likely to be obese (aOR:0.44 [0.38-0.52], with no differences in hypertension, diabetes or high (≥20%) FRS but with greater odds of high (≥5%) SCORE (aOR:1.55 [1.05-2.30]). Further adjustment for educational level, anti-HCV positivity and BMI showed higher prevalence of hypertension in PLHIV. Conclusions Despite the relative absence of obesity, PLHIV have higher prevalence of traditional CVD risk factors and higher risk of fatal CVD compared to general population. Regular screening and early management of CVD risk factors in PLHIV should be of high priority for CVD prevention. Copyright: © 2020 Touloumi et al.
