“The Rock Thane”, an open data parable

In a time long past, in a land far away, there was a once a troubled kingdom. Despite the efforts of the King to offer justice freely to all, many of his subjects were troubled by unscrupulous merchants and greedy landowners. Time and again, the King heard claims of goods not being delivered, or disputes over land. While the merchants and landowners were able to produce documents and affidavits to their defence, the King grew increasingly troubled. He felt that his subjects were being wronged, and he grew distrustful of the scribes that thronged the hallways of his courts and ...

PhD defense: Deep Representation of Lyrical Style and Semantics for Music Recommendation

Tweet Dissertation Defense Deep Representation of Lyrical Style and Semantics for Music Recommendation Abhay L. Kashyap 11:00-1:00 Thursday, 20 July 2017, ITE 346 In the age of music streaming, the need for effective recommendations is important for music discovery and a personalized user experience. Collaborative filtering based recommenders suffer from popularity bias and cold-start which is commonly mitigated by content features. For music, research in content based methods have mainly been focused in the acoustic domain while lyrical content has received little attention. Lyrics contain information about a song's topic and sentiment that cannot be easily extracted from the audio. ...

PhD Proposal: Analysis of Irregular Event Sequences using Deep Learning, Reinforcement Learning, and Visualization

Tweet Analysis of Irregular Event Sequences using Deep Learning, Reinforcement Learning, and Visualization Filip Dabek 11:00-1:00 Thursday 13 July 2017, ITE 346, UMBC History is nothing but a catalogued series of events organized into data. Amazon, the largest online retailer in the world, processes over 2,000 orders per minute. Orders come from customers on a recurring basis through subscriptions or as one-off spontaneous purchases, resulting in each customer exhibiting their own behavioral pattern when it comes to the way in which they place orders throughout the year. For a company such as Amazon, that generates over $130 billion of revenue ...

Feature for SPARQL 1.2

Jindřich Mynarz recently posted a good list of " What I would like to see in SPARQL 1.2 " and I thought I'd add a few comments as well as some of my own wished-for features. Explicit ordering in GROUP_CONCAT , and quads support for both the HTTP Graph Store Protocol and CONSTRUCT queries (items 2, 5, and 8 in Jindřich's list) seem like obvious improvements to SPARQL with a clear path forward for semantics and implementation. Here are the some of the other wished-for features: Explicitly specify the REDUCED modifier (#1) As an implementor, I quite like the fact ...

AKSW Colloquium, 07.07.2017, Two paper presentations concerning Link Discovery and Knowledge Base Reasoning

At the AKSW Colloquium on Friday 7th of July, at 10:40 AM there will be two paper presentations concerning genetic algorithms to learn linkage rules, and differentiable learning of logical rules for knowledge base reasoning. Tommaso Soru will present the paper Differentiable Learning of Logical Rules for Knowledge Base Reasoning , currently a pre-print, by Fan Yang, Zhilin Yang, and William W. Cohen. Abstract "We study the problem of learning probabilistic first-order logical rules for knowledge base reasoning. This learning problem is difficult because it requires learning the parameters in a continuous space as well as the structure in a discrete space. ...

Jennifer Sleeman dissertation defense: Dynamic Data Assimilation for Topic Modeling

Tweet Ph.D. Dissertation Defense Dynamic Data Assimilation for Topic Modeling Jennifer Sleeman 9:00am Thursday, 29 June 2017, ITE 325b, UMBC Understanding how a particular discipline such as climate science evolves over time has received renewed interest. By understanding this evolution, predicting the future direction of that discipline becomes more achievable. Dynamic Topic Modeling (DTM) has been applied to a number of disciplines to model topic evolution as a means to learn how a particular scientific discipline and its underlying concepts are changing. Understanding how a discipline evolves, and its internal and external influences, can be complicated by how the information ...

How to Design and Build Semantic Applications with Linked Data

2017-06-19, This webinar, presented by Dave Clarke, co-founder and CEO of the Synaptica® group of companies, will demonstrate how to design and build rich end-user search and discovery applications using Linked Data. The Linked Open Data cloud is a rapidly growing collection of publicly accessible resources, which can be adopted and reused to enrich both internal enterprise projects and public-facing information systems. The webinar will use the Linked Canvas application as its primary use-case. Linked Canvas is an application designed by Synaptica for the cultural heritage community. It enables high-resolution images of artworks and artifacts to be catalogued and subject ...

Ridesharing 3.0: Forget About Uber

Uber, whatever its faults, provides value to its users, both the drivers and the riders. People appreciate or even enjoy the service, even if they don't like the corporate behavior or economic disruption. Solutions seem to mostly include boycotts (in favor of taxis or competitors like Lyft) and legal action. But most of those those solutions are pushing water uphill, because people actually like the service. I have another solution: let's rebuild the service without any major company involved. Let's help software eat the world on behalf of the users, not the stockholders. In this post, I'll explain a ...

Back to Blogging

As I remember it, about ten years ago, I started this blog for one main reason. I had just watched a talk from the CTO of Second Life (remember them, when they were hot?) about his vision for how to expand by opening up the system, making it decentralized. I thought to myself: that's going to be really hard, but I've thought about it a lot; I should blog my ideas about it. As I dug into the problem, however, I realized how many sub-problems I couldn't really solve, yet. So I never posted. (Soon thereafter, Cory Ondrejka left ...
