RELATED WORK (tx) Our PubMed entity relation extraction and search problem is related to two fields of study: Medical entity relation mining and Entity-related search system. In the medical text-mining domain, there exists some prior works about the relationship among medical entities shown in the knowledge databases[1,2]. The most popular one is Comparative Toxicogenomics Database (CTD) whose data, including relations between Chemical-Gene, Chemical-Disease and Gene-Disease. Unlike the specific…

As part of the overall risk model, we have already illustrated the threats and attacks that are possible on the Costco’s IT infrastructure with the likelihood of attacks that can exploit the identified vulnerabilities, which may eventually pose an extensive threat to the Costco’s operations including missions, functions, image, and reputation as well as to the organizational assets, linked organizations, and the consumers. Costco’s privacy policy clearly enunciated the significance of customer’s…

To explain, Cartesian product represents n-tuple, which is a finite ordered list of elements. It includes all possible combination of elements in set A and set B. But binary relation only includes the combination of two elements which are respectively from set A and set B and fit the defined relationship…

Our universe was created 13.7 billion years ago. The Big Bang theory proposes that this creation resulted from the rapid expansion of matter with infinitely large density and high temperature, which marked the true origin of the universe. Physicists decided to introduce a new phenomenon called time, and agreed that “time” was born once the Big Bang banged. Simply defined, time is the measure of durations of events and the intervals between them. In non-relativistic physics, physicists consider…

The rule for first normal form (1NF) is a table in which the intersection of every column and record contains only one value. In other words a table that contains more than one atomic value in the intersection of one or more column for one or more records is not in 1NF. The non 1NF table can be converted to 1NF by restructuring original table by removing the column with the multi-values along with a copy of the primary key to create a new table. See Figure 8.4 for an example of this approach.…

While ubiquitous Internet access is extremely convenient and enables marvelous new applications for mobile users, it also creates a major security vulnerability—by placing a passive receiver in the vicinity of the wireless transmitter, that receiver can obtain a copy of every packet that is transmitted! These packets can contain all kinds of sensitive information, including passwords, social security numbers, trade secrets, and private personal messages. A passive receiver that records a copy of…
