This demonstration shows an integrated query processing environment where users can seamlessly query both a data stream management system and a sensor network with one query expression. By integrating the two query processing systems, the optimization goals of the sensor network (primarily power) and server network (primarily latency and quality) can be unified into one quality of service metri...

In this paper, we demonstrate RecDB; a full-fledged database system that provides personalized recommendation to users. We implemented RecDB using an existing open source database system PostgreSQL, and we demonstrate the effectiveness of RecDB using two existing recommendation applications (1) Restaurant Recommendation, (2) Movie Recommendation. To make the demo even more interactive, we showc...

Contextualization of knowledge has recently gained interest in the Semantic Web community and a number of logic based solutions have been proposed. In this regard, in our previous works we have introduced the Contextualized Knowledge Repository (CKR) framework: we recently extended CKR with the possibility to reason with defeasible axioms and their exceptions. The goal of this demo is to demons...

We present a tool called RIQ (RDF Indexing on Quads) for efficiently processing SPARQL queries on large RDF datasets containing quads. RIQ’s novel design includes: (a) a vector representation of RDF graphs for efficient indexing, (b) a filtering index for efficiently organizing similar RDF graphs, and (c) a decrease-and-conquer strategy for efficient query processing using the filtering index t...

This study investigates individual differences in the contribution of specific maternal regulatory behaviors to the mother–infant dyad’s regulation of infant distress response. Additionally, we examined the stability of infants’ stress responses and the stability of specific maternal soothing behaviors. The sample included 128 mother– infant dyads that were observed during an inoculation at 2 a...

Collaborative rating sites such as IMDB and Yelp have become rich resources that users consult to form judgments about and choose from among competing items. Most of these sites either provide a plethora of information for users to interpret all by themselves or a simple overall aggregate information. Such aggregates (e.g., average rating over all users who have rated an item, aggregates along ...

[email protected] ABSTRACT In this demo, we will show SGSDesigner, the ODESGS Environment user interface. ODESGS Environment (the realization of the ODESGS Framework [1]) is an environment for supporting both a) the annotation of pre-existing Grid Services (GSs) and b) the design of new complex Semantic Grid Services (SGSs) in a (semi) automatic way. In the demo we will focus in the annotation o...

In this demo paper we describe the natural language generation component of an electronic textbook application, called Inquire1. Inquire interacts with a knowledge base which encodes information from a biology textbook. The application includes a question-understanding module which allows students to ask questions about the contents of the book, and a questionanswering module which retrieves th...

Preserving data for a specific system usually depends on the system in question. Different strategies for different file types are necessary to preserve all data for a system. In this demonstration we present tools developed for preserving data for a home computer system from 1984. We present how a tool we developed can be used to retrieve data stored on audio tapes and how this data is migrate...

In 1968, Doug Englebart and his team at the Stanford Research Institute amazed the world with their oN-Line System (NLS), giving what has since been dubbed the “Mother of all Demos.” The NLS system, later renamed Augment, was the first Graphical User Interface, the first Word Processor, the first Wiki, the first Hypertext system, essentially the first of many applications we think of as modern....
