Language detection with Google's Compact Language Detector. Google's Chrome browser has a useful translate feature, where it detects the language of the page you've visited and if it differs from your local language, it offers to translate it.
Wonderfully, Google has open-sourced most of Chrome's source code, including the embedded CLD (Compact Language Detector) library that's used to detect the language of any UTF-8 encoded content. It looks like CLD was extracted from the language detection library used in Google's toolbar. SimSearch 0.2. Google Labs - Books Ngram Viewer. Natural Language Toolkit. Package Index : gensim 0.7.5. Python framework for fast Vector Space Modelling Package Documentation Latest Version: 0.9.1 Gensim is a Python library for Vector Space Modelling with very large corpora.
Target audience is the Natural Language Processing (NLP) community. All algorithms are memory-independent w.r.t. the corpus size (can process input larger than RAM),Intuitive interfaceseasy to plug in your own input corpus/datastream (trivial streaming API)easy to extend with other Vector Space algorithms (trivial transformation API)Efficient implementations of popular algorithms, such as online Latent Semantic Analysis, Latent Dirichlet Allocation or Random ProjectionsDistributed computing: can run Latent Semantic Analysis and Latent Dirichlet Allocation on a cluster of computers.Extensive HTML documentation and tutorials.
PyLucene JCC vs GCJ [Archive] I'm writing because after spending days with PyLucene versions (GCJ and JCC),I decided to share the story.
About 5 days ago I didn't even know about the existence of Lucene. I was having many difficulties indexing full-text data on MySQL - it took like 90 hours indexing ~64 million records in a single varchar(96) field. PyLucene @ Open Source Applications Foundation. Wchartype. Wchartype is a Python module for getting the types of double-byte (full-width) characters.
It has no external dependencies. wchartype is licensed under the MIT license. Usage import wchartype if wchartype.is_asian(u'\u65e5'): print u"\u65e5 is an Asian character" Function Specification.
