| Summary: | This report describes a system, from over view to detail, that allows user to extract scientific
terms from the Internet for SMS base learning. Its name is tSearch – The Term Definition
Searcher. The system receives user’s input for a scientific term, automatically searches for its
definitions on the Internet, and summarizes the definitions into one or several sentences. The
definitions are short enough (less than 160 characters), making it possible to be sent to the user
through SMS. Several text summarization algorithms have been implemented to extract short
and concise definitions from long web pages about the scientific terms. These algorithms play a
vital role in the system, as the effectiveness of the system depends largely on the speed and
correctness of the algorithms, which in turn depends on quality of the output summary. In this
project, most of time was spent on researching, implementing, and testing those algorithms.
Some standard evaluations of text summarization systems were also performed to evaluate the
performances of the algorithms. |
