Using Public Data to Fight a War

Army for use in Afghanistan? Cazoodle is using public data sources like Flickr and OpenStreetMap to build detailed guidebooks for American soldiers. Last week at Strata I sat down with company CTO Govind Kabra to find out how they do it. Its project for the Army is to build a detailed database of information about places in Afghanistan, using only public sources on the Web. The goal is to describe in detail the towns and cities including everything from names, locations and populations, as well as lists and coordinates for schools, mosques, banks and hotels.

The military already collects this sort of information, but using traditional offline sources through groups like the National Geospatial-Intelligence Agency. Origins Cazoodle was started four years ago at the University of Illinois - Urbana Champaign. An Intro To The Semantic Web: Why You Need To Know About It Sooner Than Later.

Refining UMBEL’s Linking and Mapping Predicates with Wikipedia We are only days away from releasing the first commercial version 1.00 of UMBEL (Upper Mapping and Binding Exchange Layer) [1].

Making Connections Real

To recap, UMBEL has two purposes, both aimed to promote the interoperability of Web-accessible content. First, it provides a general vocabulary of classes and predicates for describing domain ontologies and external datasets. Second, UMBEL is a coherent framework of 28,000 broad subjects and topics (the “reference concepts”), which can act as binding nodes for mapping relevant content.

Meditating on Perl, Python and the Semantic Web. I have been working on a project with the National Labs over the past several months.

Meditating on Perl, Python and the Semantic Web

A central element of that work has been an effort to bring much of the information and computatiom power of the Labs into a Service Oriented Architecture paradigm and the Semantic Web constructs are at the heart of that part of the work.

The package contains two models: one for the user’s profile and one for the user’s tweets. They then will be annotated in the “Annotator” module and converted into a list of simple triples in the “Triplifier” module. It is being implemented in PHP. There is a very good API: PHP Twiter with OAuth to help with this task. Extraction Package I started with the User Profile Model.

Object-Oriented PHP for Beginners

This tutorial was first published in July, 2010. For many PHP programmers, object-oriented programming is a frightening concept, full of complicated syntax and other roadblocks. As detailed in my book, Pro PHP and jQuery, you'll learn the concepts behind object-oriented programming (OOP), a style of coding in which related actions are grouped into classes to aid in creating more-compact, effective code. Understanding Object-Oriented Programming Object-oriented programming is a style of coding that allows developers to group similar tasks into classes. Recherche à facettes.

Recherche à facettes

La recherche à facettes (ou recherche facettée, ou navigation à facettes) est une technique en recherche d'information correspondant à une méthodologie d'accès à l'information basée sur une classification à facettes. Tunnel SSH, proxy HTTP [NoJhan - Site perso] Par nojhan le 3 septembre 2008 Quand on utilise des applications réseaux, il peut arriver que l’on soit bloqué par des administrateurs systèmes tatillons (et compétents, donc), qui vont bloquer tous les ports, sauf ceux du web, et faire passer le traffic dans un proxy HTTP.

The Federated Enterprise (Using Semantic Technology Standards to Federate Information and to Enable Emergent Analytics) I had to shorten the title a bit. Wanted you to be aware of the sort of nonsense that data warehouse people are being told: The procedure described above enabling federation based on semantic technology is not hard to build; it is just a different way of describing things that people in your enterprise are already describing using incompatible technologies like spreadsheets, text processors, diagramming tools, modeling tools, email, etc.

The semantic approach simply requires that everything be described in a single technology, RDF/OWL. Mapping Wikileaks’ Cablegate using Python, mongoDB and Gephi – Saturday, 5 Feburary 2011.

Need faster machine learning? Take a set-oriented approach. We recently faced the type of big data challenge we expect to become increasingly common: scaling up the performance of a machine learning classifier for a large set of unstructured data. Machine learning algorithms can help make sense of data by classifying, clustering and summarizing items in a data set. In general, performance has limited the opportunities to apply machine learning to understanding big or messy data sets. Analysts need to factor in time for speeding up off-the-shelf algorithms or even whether a machine learning pass would complete in a timely manner. While using smaller random samples can help mitigate performance issues, some data sets lend themselves to improved results when applied to more data. Developer Week in Review.
