Samer Hassan SSASA Objective Study the evolution of Spanish society in the period Data-Driven Agent-Based Modelling Applying several Artificial Intelligence techniques
Samer Hassan SSASA The Problem Aim: simulate the process of change in moral values in a period in a society Plenty of factors involved Nowadays, centred in the inertia of generational change: To which extent the demographic dynamics explain the mentality change?
Samer Hassan SSASA The Problem Input Data loaded: EVS-1980 Quantitative periodical info Representative sample of Spain Allows Validation Intra-generational: Agent characteristics remain constant Macro aggregation evolves

Samer Hassan SSASA Introduction of AI: Fuzzy Logic Why Fuzzy Logic? Social sciences are characterized by uncertain and vague knowledge Different concept than probability Old AdultYoungAge

Samer Hassan SSASA Introduction of AI: NLP Fuzzy logic helps for ABM qualitative input NLP helps for ABM qualitative output Experimenting with life-events generation: Output in natural language: life-story of a representative individual (Ex: hyper-inflation) Applications: NL format makes direct comparison with real stories possible Information very simple for any individual to understand Complementing explanations of quantitative research
Samer Hassan SSASA Quantitative & Qualitative Output Generation
Samer Hassan SSASA An example: part of the XML output
Samer Hassan SSASA An example: part of the life-story generated Rosa Pérez was born in 1955, and she met Luis Martínez, and she met Miguel López. She suffered a horrible childhood, and she had a very good friend: María Valdés, and she believed in God, and she used to go to church every week.... When she was a teenager, (...) she had problems with drugs, and she became an adult, and she met Marci Boyle, and while she was involved in a labour union, she met Carla González and she got arrested. She learned how to play the guitar, and so she became a hippy, getting involved in a NGO.... She met Sara Hernández, and she stopped going to church, and she met Marcos Torres, and she fell in love, desperately, with Marcos Torres, but in the end she went out with Miguel López, and she co-habitated with Miguel López, and she had a child: Melvin López.... She met Sergio Ruiz, and she separated from Miguel López, and she went out with Sergio Ruiz, and she co-habitated with Sergio Ruiz. She had a abortion, and so she had a depression, and she had a crisis of values. She was unfaithful to Sergio Ruiz with another man.... Nowadays she is an atheist.

Samer Hassan SSASA Introduction of AI: Data Mining Data Mining is the process of extracting patterns and relevant information from large amounts of data Design: Allows simplification, locates redundant attributes Pre-processing of empirical data (surveys): Clustering: selection of qualitative “ideal types” Post-processing of simulation output: Clustering: Shows non-visible patterns Comparison of patterns Different life-stories for each pattern Classification: evolution of “ideal types”
Samer Hassan SSASA Limitations & Future Work Enough demography! Overcome methodological limitation: implementing diffusion of moral values Quest for a proper cognitive model for this task...or forget about it definitely not BDI Improve other aspects: ABM design (Ex: friendship ties may weaken) Fuzzy inference Quality of biographies
