HOW TO MAKE A PIE: REPRODUCIBLE RESEARCH FOR EMPIRICAL ECONOMICS AND ECONOMETRICS
2020
Les recherches empiriques en sciences humaines et sociales necessitent la manipulation de nombreux fichiers : differents jeux de donnees, de multiples programmes, qu'ils soient destines a la manipulation de donnees, aux traitements statistiques, aux estimations econometriques ou a des simulations, et de nombreux fichiers successifs de resultats. Maitriser l’ensemble des etapes du projet de recherche est indispensable si l’on souhaite pouvoir reproduire ou repliquer les resultats a long terme. Cette rigueur (fiabilite, tracabilite, reproductibilite), est desormais de plus en plus exigee par notre profession ainsi que par les editeurs de revues scientifiques. Apres avoir mis en evidence les e…
Similarity Mashups for Recommendation
2013
Recommendation systems are becoming a state of the art for web-based systems as they produce additional product exposure and customer satisfaction. The Semantic Web and mashups can improve recommendation systems and provide new ways for their creation. In the web it is possible to analyze product descriptions and to use Linked Data for characterizing the similarity of objects or of objects and user interests. In this chapter, we give a brief overview of existing technical approaches and tools for creating recommendation systems that can be used to create mashups as recommendation systems.
Publication Network Analysis of an Academic Family in Information Systems
2011
The study of scientific collaboration through network analysis can give interesting conclusions about the publication habits of a scientific community. Co-authorship networks represent scientific collaboration as a graph: nodes correspond to authors, edges between nodes mark joint publications (Newman 2001a,b). Scientific publishing is decentralized. Choices of co-authors and research topics are seldomly globally coordinated. Still, the structure of co-authorship networks is far from random. Co-authorship networks are governed by principles that are similar in other complex networks such as social networks (Wasserman and Faust 1994), networks of citations between scientific papers (Egghe an…
SIS-M
2012
In this paper we describe the outcome of the SIS-M project, consisting in the development of web support system for the teacher of an inclusive school. In this kind of centers, the ordinary training is developed with people with disabilities. Although the availability of adequate supports, the management of the school and the heterogeneity of students requires tools that help in day to day. SIS-M provides tools that supports the basic management of the school, and due to the use of natural language processing tools, ontologies and location in real time, allows that the educator could receive the sugestion of activities that the system considers most appropriate for students in class at all …
Ontology-Based Information System
2014
We describe a novel way for creating information systems based on ontologies. The described solution is aimed at domain experts who would benefit from being able to quickly prototype fully-functional, web-based information system for data input, editing and analysis. The systems backbone is SPARQL 1.1 endpoint that enables organization users to view and edit the data, while outside users can get read-only access to the endpoint. The system prototype is implemented and successfully tested with Latvian medical data ontology with 60 classes and imported 5 000 000 data-level triples.
Using Semantics to Manage 3D Scenes in Web Platforms
2005
Computer graphics has widely spread out into various computer applications. After the early wire-frame computer generated images of the 60s, spatial representation of objects improved in the 70s with Boundary Representation (B-Rep) modeling, Constructive Solid Geometry (CSG) objects, and free-form surfaces. Realistic rendering in the 90s, taking into account sophisticated dynamic interactions (between objects or between objects and human actors, physical interactions with light, etc.) now make 3D-scenes much better than simple 3D representations of the real world. Indeed, they are a way to conceive products (industrial products, art products, etc.) and to modify them over time, either inter…
Freenet-like GUIDs for implementing xanalogical hypertext
2002
We discuss the use of Freenet-like content hash GUIDs as a primitive for implementing the Xanadu model in a peer-to-peer framework. Our current prototype is able to display the implicit connection (transclusion) between two different references to the same permanent ID. We discuss the next layers required in the implementation of the Xanadu model on a world-wide peer-to-peer network.
Bridging Heritage and Tourist UX: A Socially-Driven Perspective
2016
The paper illustrates the potential of smart-phones as a medium of exchange of memories and experiences. Our application aims at providing diverse types of cultural user experience: to enable tourists to explore new places from a social-driven perceptive; to support new forms of connection and interaction between users and information (data exchange, contents sharing, feedback); to compose interactive narrative conveying the richness of information of interest to the user; to allow users to experience the narrative and underlying physical environment as a mixed-reality experience while allowing for deeper, context-specific exploration at any time through AR system.
Library for model querying
2012
Query and transformation languages make it easy to work with models, but they are bound to one particular data store. That makes them hard to adopt in projects where data is stored in a different repository, which hinders more widespread use of transformations and models. Instead of adopting a transformation language to a new data store, we propose to build a query and transformation library for the general-purpose language that is already used in a project. In this paper we demonstrate that it can be easily by implementing such a library for an EMOF-like data store in the Lua language.
Combined People Position and Compass Detection for Context-aware Service Provision
2006
A novel technique is discussed for people identification and position sensing in augmented reality by the use of two cooperating technologies. People are provided with RFID tags for localization and context definition, and then visually investigated for identity checking and compass detection. The two technologies are discussed within an implementation of a case study dealing with context aware service provision for students in a campus.
