Searchable: Annotation-Driven Indexing and Searching with Lucene :: Drive-by Digressions

by karlcow

Searchable is a toolkit for Lucene that harnesses the power of annotations to specify what properties to index and how to treat them.

PhotoMaker

by karlcow

This small mashup uses YQL to combine the power of Flickr and Yahoo! Placemaker. Copy and paste some text into the textbox below and click the button — application will first geo-locate all places in the text, and then will try to find photographs, published under Creative Commons license, which were geotagged at or near found places.

interesting how Placemaker reacts differently to a text with "Rouen" and "at Rouen"

MIT Media Lab: Reality Mining

by karlcow & 1 other

Reality Mining defines the collection of machine-sensed environmental data pertaining to human social behavior. This new paradigm of data mining makes possible the modeling of conversation context, proximity sensing, and temporospatial location throughout large communities of individuals. Mobile phones (and similarly innocuous devices) are used for data collection, opening social network analysis to new methods of empirical stochastic modeling.

The original Reality Mining experiment is one of the largest mobile phone projects attempted in academia. Our research agenda takes advantage of the increasingly widespread use of mobile phones to provide insight into the dynamics of both individual and group behavior. By leveraging recent advances in machine learning we are building generative models that can be used to predict what a single user will do next, as well as model behavior of large organizations.

QDC 2007

by parmentierf
Cet atelier se concentre sur les méthodes, et les techniques d’analyse et d’évaluation de qualité au sens large, en fouille de données et en gestion des connaissances. On s’intéressera ainsi à la qualité des données (nettoyage des données, méthodologies de prétraitement, métriques d’évaluation et approches algorithmiques), à l’évaluation de la qualité des modèles en fouille de données (méthodes, algorithmes, et études sur les mesures d’intérêt, agrégation de préférences, classification des connaissances, post-traitement des résultats) et gestion des connaissances (qualité des ontologies, qualité des alignements, analyse des usages).
