Do it in two parts. The first part is lossless text compression, the second part is sentence level text summarization, called lossy text compression.Do not send too high expectations to the second part, because the big probability is not finished, after all, I have no contact with this field.Lossless text CompressionOverall introduction. The internet produces too much text (is it a pseudo proposition?) Storage and propagation is not economical if compression is not performed. At the time of inst

conversation, to the current content, the answer refers to the content of the response. In other words, the context can be a number of dialogues, and the answer is a response to a number of dialogues. A positive sample means that the context of the sample and the answer is a match, and, correspondingly, the negative sample refers to the mismatch between the two-the answer is taken randomly from somewhere in the corpus. The following figure is a partial display of the training dataset: You will

Using Python to create a vector space model for text, We need to start thinking about how to convert a set of texts into quantifiable things. The simplest method is to consider word frequency. I will try not to use NLTK and Scikits-Learn packages. First, we will use Python to explain some basic concepts. Basic Term Frequency First, let's review how to get the number of words in each document: A Word Frequency Vector. #examples taken from here: http://

Python: the usage of configparse and optparse is different. An example is provi

above mentioned NumPy, there are scipy, NLTK, OS (comes with) and so on. Python's flexible syntax also makes it easy to implement very useful features, including text manipulation, list/dict comprehension, and so much more efficiently (writing and running efficiently), with lambda and more. This is one of the main reasons behind the benign ecology of Python. In contrast, Lua is also the interpretation of language, and even the luajit of this artifact
module based on the BSD open source license.Scikit-learn installation needs NumPy Scopy Matplotlib and other modules, the main functions of Scikit-learn are divided into six parts, classification, regression, clustering, data reduction, model selection, data preprocessing. Scikit-learn comes with some classic datasets, such as the iris and digits datasets for classification, and the Boston house prices dataset for regression analysis. The dataset is a dictionary structure, and the data is store
I had learnt and also to improve my coding skill. Kaggle is a great place for data scientists, and it offers real world problems and data from various domains.Do you have any prior experience or domain knowledge that helped you succeed in this competition?I have a background of image proecssing and has limited knowledge about NLP except BOW/TF-IDF kinda of things. During the competition, I frequently refered to the book Python Text processing with NLTK
Read IOB format and CoNLL2000 block Corpus CoNLL2000 is the text that has been loaded with the annotation. It uses the IOB symbol to block it. This corpus provides NP, VP, and PP types. For example: hePRPB---- Function of chunk. conllstr2tree (): Creates a tree representation of a string. For example: >>>text = >>>nltk.chunk.conllstr2tree(text,chunk_types=[]).draw() Running result: >>>>>> Conll2000.chunked _ sents () [99 // DT cup //// NNPStone // Fortran $ story //.) >>> conll2000.chunked
