Balie & YooName thesis

Balie, and its NER extension called YooName, are thoroughly described in the PhD thesis titled "Semi-Supervised Named Entity Recognition: Learning to Recognize 100 Entity Types with Little Supervision".

The thesis was successfully defended some weeks ago and is now available online at http://cogprints.org/5859/.

Balie 1.65 released - qTag removed

qTag (external product) was removed from Balie in this release.

Note that we maintain a distinct qTag wrapper in the CVS. It offers the exact same part-of-speech annotation function.

Release 1.65 also corrects some minor bugs and allows NER alias network information to be printed in XML output.

Important: Java 1.5 is now required!

- Since Balie v1.5, Java 1.5 is required (use of typed collections and enumerations)

- Balie v1.2 was the last version compliant with earlier versions.

Posted by David N. 2007-01-18

Balie 1.5

Compliance with Java 1.5 and code improvements:

- Generalization of NER module (lower accuracy but greater scalability)

- Lot of token features now available: word-level (casing, numeric, single char), morphology, functional features from litterature. etc.

- Code beautification, maintenance, etc.

Enjoy!

Balie Welcomes a new Developper!

We are happy to welcome Divan_Roulant, an experienced Java developper. Divan_Roulant will work on morphology (e.g.: flexion suffixes) as well as maintenance and bug fixes on the core modules of Balie.

Balie and CohenWrapper new releases

Balie main change is the new Iterator object to loop through the TokenList. This is a more intuitive way to handle the text.

CohenWrapper was redesigned and generalized. It is now easier to use on other tasks. Two new features were added (in comparison to Cohen published algorithm): row and column number of the innermost table. Also, an optional noise filter and an optional cost-sensitive classification module were added.

- lang identification now return probability estimates,
- better charset handling,
- many bug fixes (major: lang id optimization was corrupting the model),
- code inspection (IDEA inspector and jlint),
- better punctuation classes,
- improved language specific class architechture

Balie technical report

This report presents Balie, a system for multilingual textual information extraction (IE). IE consist in finding and structuring data from free-written texts. Examples of IE tasks include named-entity recognition (NER), identification of proteins, abbreviation resolution, keyphrase extraction, identification of semantic roles and a large amount of much specific tasks (e.g.: finding e-mails, urls). Some tasks, like the last ones, may be easily tackled by the use of regular expressions or simple rules. However, more complex tasks like NER, require efficient and flexible architecture. Balie is driven by the need of such a flexible IE architecture. ... read more

Balie 1.05 & CohenWrapper 1.01

Balie 1.05: major improvements for language identification module.

Cohen Wrapper 1.05: now includes probability estimates to force at least 1 positive node (in news content extraction)

----

Balie is designed to support textual information extraction tasks.

Balie supports English, French, Spanish, German and now, Romanian!

Given a text, it will (1) identify the language, (2) tokenize the text, (3) detect sentence boundaries and (4) guess part-of-speech for each token. ... read more

Balie extension: introducing Cohen Wrapper 1.0!

Balie is designed to support textual information extraction tasks.

Given a text, it will (1) identify the language, (2) tokenize the text, (3) detect sentence boundaries and (4) guess part-of-speech for each token.

The Cohen Wrapper is an extension to Balie.
This is a web page wrapper that can be trained to recognize desired parts of a web page.

Two wrappers are already trained:
(1) a wrapper that recognize news items in a newspaper homepage;
(2) a wrapper that recognize relevant text in a news article.
