A Digital Ecosystem-based Framework for Math-based Search System

摘要

Sructured information is one type of web information. Text-based search engines fall short in retrieving such this type of information. For example, when a user search for x(y+x) using Google, Google retrieves documents that have xyz, x+y=z, (x+y)=xyz or any other document that contains x, y, and/or z but not x(y+x) as a stand alone expression. Google ignores the structure of the expression x(y+x) because Google is not supported with the required tools to increase the accuracy when searching for math expressions. Searching for different kinds of mathematical constructs require special processing and tools because of the nature of those expressions. For example, the structure of a mathematical expression contains much information. The structure of certain math expressions conveys the correct interpretation of those expressions. In this research, a framework for math-based search system is proposed and presented. This system is based on the digital ecosystems concepts. The detailed description of this framework is presented in the following sections. This framework supposed to provide users with promising results as will be explained.
