Political Hashtag Trends (PHT) is an analysis tool for political leftvs.-right polarization of Twitter hashtags. PHT computes a leaning for trending, political hashtags in a given week, giving insights into the polarizing U.S. American issues on Twitter. The leaning of a hashtag is derived in two steps. First, users retweeting a set of “seed users” with a known political leaning, such as Barack...

Following the job-centric monitoring concept, Job Provenance (JP) service organizes provenance records on the per-job basis. It is designed to manage very large number of records, as was required in the EGEE project where it was developed originally. The quantitative aspect is also a focus of the presented demonstration. We show JP capability to retrieve data items of interest from a large data...

This demo paper presents a system that builds a timeline with salient actions of a soccer game, based on the tweets posted by users. It combines information provided by external knowledge bases to enrich the content of tweets and applies graph theory to model relations between actions (e.g. goals, penalties) and participants of a game (e.g. players, teams). In the demo, a web application displa...

Methods Hospital records of patients with a diagnosis of chronic arthritis with onsen at the age of 16 years or less presenting to University Hospital Center, “Mother Teresa”, Tirana for the periods July 2010 – March 2014 were retrospectively reviewed and reclassified as juvenile idiopathic arthritis (JIA) based on the International League of Associations for Rheumatology (ILAR) diagnostic crit...

This work presents the query language TQL, a query language for semistructured data, that can be used to query XML files. TQL substitutes the standard path-based pattern-matching mechanism with a logic-based mechanism, where the programmer specifies the properties of the pieces of data she is trying to extract. This feature makes some queries easier to express, and should allow the adoption of ...

The exploitation of content in the area of cultural heritage is a critical issue. There is a strong push on defining and collecting content metadata from cultural institutions (such as museums, university, archives, library, foundations, etc.) to see them accessible on Europeana for a larger audience, the so called European digital library. This action is going to reduce fragmentation and to in...

In this demonstration, we will present our online parser that allows users to submit any sentence and obtain an analysis following the specification of AMR (Banarescu et al., 2014) to a large extent. This AMR analysis is generated by a small set of rules that convert a native Logical Form analysis provided by a preexisting parser (see Vanderwende, 2015) into the AMR format. While we demonstrate...

Context representation of (description logic based) 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 DL based Contextualized Knowledge Repository (CKR) framework: we recently proposed an extension of CKR with the possibility to represent and reason with defe...

Observers watched videotaped face-to-face mother–infant and stranger–infant interactions of 12 infants at 2, 4, or 6 months of age. Half of the observers saw each mother paired with her own infant and another infant of the same age (mother tapes) and half saw each infant paired with his or her mother and with a stranger (infant tapes). Observers were asked to judge which was the mother–infant d...

The paper presents two prototypes for the estimation of human energy expenditure during normal daily activities and exercise. The first prototype employs two dedicated inertial sensors attached to the user’s chest and thigh and a heart rate monitor. The second prototype uses only the accelerometer embedded in a smart phone carried in the user’s pocket. Both systems use machine learning for the ...
