A Polygen Model for Heterogeneous Database Systems: The Source Tagging Perspective

A Polygen Model for Developing Heterogeneous Database Systems With Source Tagging Capabilities

A Source Tagging Theory for Heterogeneous Database Systems

Many important Management Support Systems require seamless access to and integration of multiple heterogeneous database systems. This paper studies heterogeneous database systems from the source perspective. It aims at addressing issues such as the following: (1) Where is the data from? (2) Which intermediate data sources were used to arrive at that data? Specifically, it presents a polygen mod...

برچسب‌گذاری ادات سخن زبان فارسی با استفاده از مدل شبکۀ فازی

Part of speech tagging (POS tagging) is an ongoing research in natural language processing (NLP) applications. The process of classifying words into their parts of speech and labeling them accordingly is known as part-of-speech tagging, POS-tagging, or simply tagging. Parts of speech are also known as word classes or lexical categories. The purpose of POS tagging is determining the grammatical ...

An improved joint model: POS tagging and dependency parsing

Dependency parsing is a way of syntactic parsing and a natural language that automatically analyzes the dependency structure of sentences, and the input for each sentence creates a dependency graph. Part-Of-Speech (POS) tagging is a prerequisite for dependency parsing. Generally, dependency parsers do the POS tagging task along with dependency parsing in a pipeline mode. Unfortunately, in pipel...

Systems Risk Analysis UsingHierarchical Modeling

A fresh look at the system analysis helped us in finding a new way of calculating the risks associated with the system. The author found that, due to the shortcomings of RPN, more researches needed to be done in this area to use RPNs as a new source of information for system risk analysis. It is the purpose of this article to investigate the fundamental concepts of failure modes and effects ana...
