This paper describes the TRRD systems entered in the TAC 2013 entity linking challenge. We explore a restricted version of the task that accesses only an entity authority file with (possibly noisy) alternative names and plain text from the target domain. This is designed to reflect the problem of linking to existing entity authorities within companies like Thomson Reuters. We used the 2013 shar...

Dark Energy is currently one of the biggest mysteries in science. In this article the origin of the concept is traced as far back as Newton and Hooke in the seventeenth century. Newton considered, along with the inverse square law, a force of attraction that varies linearly with distance. A direct link can be made between this term and Einstein’s cosmological constant, Λ , and this leads to a p...

In this paper, we discuss the capacity region of the deterministic Y-channel with private and common messages. Each user aims to deliver two private messages to the other two users in addition to a common message directed towards both of them. As there is no direct link between the users, all messages must pass through the relay. We present outer-bounds on the rate region using genie aided and ...

Capability indices measure the performance of a process. Although process yield is the primary focus on the performance criteria, the " ( , ) p C u v indices combine process yield and process centering. With this compromise, there is no direct link between the process yield and these indices, but literature provides lower and upper bounds for the process yield. However errors in the proposed re...

Research emerging from different fields of organizational analysis has linked both market orientation and strategic human resource management (SHRM) to organizational performance. Although both concepts are premised on the management of organizational culture, no study has investigated their interrelationship or the dynamics between the two concepts and organizational performance. The findings ...

Data quality improvement is becoming an increasingly important issue. In contexts where data are replicated among different sources, data quality improvement is possible through extensive data comparisons: whereas copies of same data are different because of data errors, comparisons help to reconcile such copies. Best quality copies can be selected or constructed in order to correct other copie...

Linking records from two or more databases is becoming increasingly important in the data preparation step of many data mining projects, as linked data can enable analysts to conduct studies that are not feasible otherwise, or that would require expensive and timeconsuming collection of specific data. The aim of such linkages is to match all records that refer to the same entity. One of the mai...

BACKGROUND Methods for linking real-world healthcare data often use a latent class model, where the latent, or unknown, class is the true match status of candidate record-pairs. This commonly used model assumes that agreement patterns among multiple fields within a latent class are independent. When this assumption is violated, various approaches, including the most commonly proposed loglinear ...

Background: Immobilization is an approach in industry to improve stability and reusability of urease. The efficiency of this technique depends on the type of membrane and the method of stabilization. Methods: The PEI-modified egg shell membrane was used to immobilize urease by absorption and glutaraldehyde cross-linking methods. The membranes were characterized by Fourier-transform infrared sp...
