Powerful text summarization engine. Extractor is a software text summarization engine. It consumes documents (text, html, email) and using a patented genetic extraction algorithm (GenEx) analyzes the recurrence of words and phrases, their proximity to one another, and the uniqueness of the words to a particular document. The engine returns a list of key words and phrases found in the document together with their relative ranking (how many times was the word/phrase found in the document) along with contextual links back to the position of the key word/phrase in the document itself.

What is text summarization?
By definition text summarization is: To comprise in, or reduce to, a summary; to present briefly; quickly executed.

In terms of computer automated text summarization there are many definitions and implementations including Bayesian, Heurstics and linguistics. Extractor uses a Genetic approach which in itself provides a learning process. This is important for the summarization utility to move from one domain to another, versus other approaches which are traditionally domain specific and thereby require greater human intervention to adjust from one domain to another.

The Extractor API's have been designed for maximum flexibility allowing a wide variety of applications to take advantage of this unparalleled technology... supported development languages include:

• C (C, C++, VC++)
• Java
• Visual Basic
• Python
• Perl

There are 26 primary API function calls that provide the development team with full control of the Extractor DLL and presentation of the extracted results.

Extractor supports Windows, Solaris and Linux computing platforms. Other computing platforms such as HP/UX, AIX or the Mac O/S can be custom compiled. (Upon confirmation of computing platform and engagement of the custom compilation, the process can take from one to two weeks for final testing and release.)

Multiple Threads with the Extractor API ... The API for Extractor allows several documents to be processed simultaneously, using separate threads for each document. This is useful, for example, when processing web pages. A major bottle-neck when downloading web pages is waiting for web servers to respond to requests for pages. One way around this bottle-neck is to download several pages simultaneously, using a separate thread to process each page.

Extractor is fully reentrant, to allow multithreading without the use of Win32 services such as semaphores and the EnterCriticalSection and LeaveCriticalSection functions. There should be a one-to-one relationship between threads and DocumentMemory values, so only one thread reads or writes to a given DocumentMemory. On the other hand, there may be a many-to-one relationship between threads and StopMemory values. That is, many threads may simultaneously read one StopMemory.

Most functions that take StopMemory as an argument only read StopMemory; they do not write. This is why many threads can safely access the same StopMemory. However, the functions ExtrAddStopWord and ExtrAddStopPhrase write StopMemory. These two functions should be called (one after the other; not at the same time) before any other threads access StopMemory. If one thread calls ExtrAddStopWord or ExtrAddStopPhrase with a given value of StopMemory while a second thread calls any function with the same value of StopMemory, the memory may become corrupted.

Applications of Text Summarization concepts: Text summarization is used in many applications. Most notably text summarization is used for:

• Content review - defining document suitability.
• Pre-Sort document summaries for Cataloging.
• Creating document Indexes.
• Providing interactive query refinement.
• Defining document trends - performing document trend analysis.
• Assisting in web page content analysis. Determining web page content accuracy
• Enhancing Document Management systems.

Version History: The Extractor technology started as a machine learning and artificial intelligence research project at the National Research Council of Canada in the mid 1990's. In January of 1997 the initial result of that R&D effort was the release of the first version of Extractor. To this day research and development is ongoing through the exceptional efforts of Dr. Peter Turney at the Interactive Information Technology Group at the National Research Council of Canada and DBI Technologies Inc.
