Welcome to CooCooWakka!!!
也许Wiki的概念本来就是有一点点奇怪的，但是我相信只要你花一点时间阅读一下Wiki站点，很可能会产生兴趣哦～～


GATE is written in Java and very Java centric. This makes it portable, fast, and heavyweight. A programming library is available.  It's 14 years old and has many users and contributors.
CooCooWakka是一个Wiki引擎——一套实现Wiki的服务器PHP脚本。Wiki是在线协作与网络社团的革命性的一种新形式。
 
简单来说，对于基于CooCooWakka的网站，任何人（包括你！）都可以在线编辑他的几乎（视管理员意愿）任何页面。CooCooWakka可以用于共笔系统、读书会、档案开发、写书、翻译、资料整理（例如课堂笔记、软件使用资料）、常见问题整理等等。由于其使用及扩展方面的快速便捷，CooCooWakka甚至可以作为小型的CMS系统。本站便是一个基于CooCooWakka的Wiki站点。

* GATE developer is used to process sets of Language Resources in Corpus using Processing Resources. They are typically saved to a serialized Datastore.
* ANNIE, VG (verb group) processors.
* Preserve formatting embeds tags in HTML or XML.
** Different strengths using GATE's graph (node/offset) based XML vs. preserved formatting (original xml/html)
 
= Information Extraction =
 
* IR - retrieve docs
* IE - retreive structured data
 
* Knowledge Engineering - rule based
* Learning Systems - statistical
 
Old Bailey IE project  - old english (Online)
 
* POS - assigned in Token (noun, verb, etc)
 
* Gazateer - gotcha, have to set initialization parameter listsURL before it's
loaded. Must also "save and reinitialize."
* Gazeteer creates Lookups, then transducer creaties named entities
* Then orthomatcher (spelling features in common) coreference associates those
 
* Annotation Key sets and annotation comparing
** Need setToKeep key in Document Reset for any pre annotated texts
 
== Evaluation / Metrics ==
 
* Evaluation metric - mathematically against human annotated
* Scoring - performance measures for annotation types
 
* Result types - Correct, missing, spurious, partially correct (overlapped)
 
* Tools > Annotations Diff - comparing human vs machine annotation
 
* Corpus > Corpus quality assurance - compare by type
* (B has to be the generated set)
 
* Annotation set transfer (in tools) - transfer between docs in pipeline
** useful for eg HTML that has boilerplate
 
= Other notes =
 
== Lucene data store and ANIC ==
 
* Use <null> for default set
* Go to Datastore for queries
** eg {Person}({Token})+{Money}
* Useful for debugging JAPE and results
 
[[File:GATE-lucene-person-money.png|800px]]
 
== To investigate ==
 
* markupAware for HTML/XML (keeps tags in editor)
* AnnotationStack
* Advanced Options
 
= JAPE =
 
* Rules based on tokens and lookups
 
== To review, gotchas ==
 
* Rule types : first takes only first match, excludes compound
** a? b for "a b" will match "a b"
* multiplexor tranducers
* multi-constraint statements
* macros
* To reuse created annotations has to be a separate rule
 
= To follow up =
 
* WebSphinx crawler CREOLE plugin
 
= Demos =
 
* Translating parts of speech between languages using Compound editor and Alignment editor
* Predicate extractor (MultiPaX)
** Mixed results at best
* OwlExporter
** NLP ontology
 
= Conclusions =
 
While it can do a lot out of the box and benefits from development time and breadth of connectivity, to be useful to more than patient specialists, it needs usability testing. A lot of things are inobvious and too domain specific that with a bit of work could be more broadly useful. Interaction could include a lot more immediate, useful and interesting looking displays. A web based version could have these features. However the team seems somewhat ambivalent about development. :)
