MontyLingua - 自然语言处理工具软件
Free Software Blog里提到了它,MontyLingua是一个流行的自然语言处理工具,它能够根据人的常识来理解英语语言,世界各地有很多人都在用它进行语言研究。官方网站有一段介绍:
python documentation and api (html) [.html]
java documentation and api [.html]
MontyLingua is a free*, commonsense-enriched, end-to-end natural language understander for English. Feed raw English text into MontyLingua, and the output will be a semantic interpretation of that text. Perfect for information retrieval and extraction, request processing, and question answering. From English sentences, it extracts subject/verb/object tuples, extracts adjectives, noun phrases and verb phrases, and extracts people's names, places, events, dates and times, and other semantic information. MontyLingua makes traditionally difficult language processing tasks trivial!MontyLingua performs the following tasks over text:
- MontyTokenizer - Tokenizes raw English text (sensitive to abbreviations), and resolve contractions, e.g. "you're" ==> "you are"
- MontyTagger - Part-of-speech tagging based on Brill94, enriched with common sense.
- MontyChunker - Lightning fast regular expression chunker
- MontyExtractor - Extracts phrases and subject/verb/object triplets from sentences
- MontyLemmatiser - Strips inflectional morphology, i.e. changes verbs to infinitive form and nouns to singular form
- MontyNLGenerator - Uses MontyLingua's concise predicate-arg representation to generate naturalistic English sentences and text summaries

READ THIS if you are running ML on Mac OS X, or Unix
The distribution ZIP includes datafiles designed for windows. If you are running MontyLingua on Unix or Mac OS X, and the phrase "I love you" is tagged incorrectly, then the datafiles need to be rebuilt. This is simple:
- delete all files of the form, FASTLEXICON_n.MDF, where n is a number.
- re-run the MontyLingua program, either from Python, or Java, and the correct datafiles will be rebuilt. If running Java and you run out of memory during the rebuild process, use the -MX or -Xmx option in Java to increase the memory size. You will only need to rebuild these datafiles once.

匈牙利和鞑靼斯坦推广免费开源软件(FOSS)
Slashdot:好像几乎每隔一周就会有新的消息说又有一个政府决定采用免费开放源码软件。两个最近的消息来自匈牙利和鞑靼斯坦共和国(独立前属俄罗斯)。在4月2日,匈牙利政府信息技术部副部长费伦茨巴哈宣布,将修改其采购规则,要求付费专有软件开支不得超过对开源软件的投资。在有380万人口的鞑靼斯坦共和国, 教育部副部长宣布,到这个学年底,所有2400个鞑靼斯坦教育机构将跟随2008年成功实施的试点项目,全面过渡到GNU / Linux。
