In this paper are described the results of the information analysis of structures represented by graphs. The obtained information estimation (IE) are based on an entropy measure of C. Shannon. The orthogonal characteristics of the graphs are taken into account: vertexes and contours (paths for the graphs of the type “tree”). Obtained IE is univalent both for the non-isomorphic and for the isomo...

Information Extraction (IE) is a fundamental technology for NLP. Previous methods for IE were relying on co-occurrence relations, soft patterns and properties of the target (for example, syntactic role), which result in problems of handling paraphrasing and alignment of instances. Our system ARE (Anchor and Relation) is based on the dependency relation model and tackles these problems by unifyi...

The rise of Big Data analytics over unstructured text has led to renewed interest in information extraction (IE). These applications need effective IE as a first step towards solving end-to-end real world problems (e.g. biology, medicine, finance, media and entertainment, etc). Much recent NLP research has focused on addressing specific IE problems using a pipeline of multiple machine learning ...

A total of 14 cases of infective endocarditis (IE) in children aged 6 months to 10 years were seen from December 1987 to December 1992 at the pediatric unit of Ayatollah Taleghani Medical Center. The majority of patients (12 of 14) were between 5 and 10 years of age. Acyanotic congenital heart disease was known to preexist in 78.6% and rheumatic valvular heart disease in 21.4% of cases. Or...

A Job Shop Scheduling Problem (JSSP), where p processes and n jobs should be processed on m machines so that the total completion time is minimal, a well-known problem with many industrial applications. Many researchers focus JSSP classification algorithms address different classes. In this research work, production times, very theme covered in Industrial Engineering (IE), are integrated into a...

We present an information extraction system for patient records which has been submitted to the ShARe/CLEF eHealth Evaluation Lab 2014 Task 2. The task was information extraction from clinical text in terms of a disease/disorder template filling process. The system uses a lexicalized parser to annotate grammatical relations between diseases, disorders, and other constituents on a sentence level...

The convergence of communications and information technology within education, as well as more widely, means that concepts developed within ITS & AIED are now applicable to a wider range of wired, and more interestingly 'wireless', technologies. Interactive TV, supported by broadband broadcasting, offers interesting possibilities for education. The use of TV (and radio) in education has a long ...
