Natural Language Processing 3.7-use a regular expression for text segmentation, natural language processing 3.7
1. Simple word segmentation method:
Text Segmentation by space characters is the easiest method for text segmentation.
Natural Language Processing 3.6-normalized text, natural language processing 3.6
In the previous example, the text is often converted into lowercase letters before being processed, that is, (w. lower () for w in words ). use lower
Once wrote a small article, beginners how to access Natural language processing (NLP) field of academic materials _zibuyu_ Sina Blog, perhaps for your reference.
Yesterday, a group of students in the laboratory sent an e-mail to ask me how to find academic papers, which reminds me of my first graduate students at a loss of Si gu situation: watching the senior

There is a preliminary understanding of many of the technical principles of NLP. It can be said to be the best introductory reading of natural language processing.

Natural language Processing--TF-IDF algorithm to extract key words
This headline seems to be very complicated, in fact, I would like to talk about a very simple question.
There is a very long article, I want to use the computer to extract its keywords (Automatic keyphrase extraction), completely without manual intervention, how can I do it correctly.

It mainly includes capitalization conversion, stemming, simplified conversion and so on.
Segmentation (sentence segmentation and decision Trees):
Like!? Such symbols are clearly divided in meaning, but in English. " "will be used in a variety of scenarios, such as the abbreviation" INC "," Dr ",". 2% "," 4.3 "and so on, can not be processed by simple regular expression, we introduced the decision tree classification method to determine whether th
, K2, K3.Measurement of Ishimarkov language model: complexity (perplexity)Suppose we have a test data set (a total of M sentences), each sentence Si corresponds to a probability p (SI), so the probability product of the test data set is ∏p (SI). After simplification, we can get Log∏p (si) =σlog[p (si)]. perplexity = 2^-l, where L = 1/mσlog[p (SI)]. (like the definition of entropy)A few intuitive examples:1) Suppose Q (w | u, v) = 1/m,perplexity = M;2)
systems must therefore have a better ability to deal with unknown language phenomena, and fault tolerance for various possible input forms (robustness of the system). Of course, there are many other problems, such as how to deal with differences in different languages, how to extract text features, lack of resources, low coverage, difficulties in knowledge representation. basic methods Years, nearly 30 years of time hastily passed, when I wa
