pl1936-Big Data Fast Data mining platform RapidMiner data analysisEssay background: In a lot of times, many of the early friends will ask me: I am from other languages transferred to the development of the program, there are some basic information to learn from us, your frame feel too big, I hope to have a gradual tutorial or video to learn just fine. For learning difficulties do not know how to improve the

, add 1 or subtract 1. If the value is greater than 0, positive; if it is less than 0, negative. So what if the value is equal to 0? C. If it is equal to or equal to 0 The emotional direction of the current sentence is the same as that of the previous sentence.. Because users prefer to praise or criticize only items in the same paragraph (including multiple sentences. (9) Summary generation:The final step is to calculate the number of positive or negative sentences that each feature belongs. Th

its description document.5. Classification effectThe above does not refer to the test process, for the above example, the KNN first two parameters are used train, because the same data set. So the result is the correct rate can reach 100%. In the case of more training sets. Can be randomly assigned to 7:3 or 8:2 in two parts, the former training the latter to do the test is good. There is no longer a detailed statement.In cases where the classification effect is not ideal. Improve the classific

Regardless of the text processing, machine learning and data mining, all need data, in addition to through som

During text mining, the wildcards (Wildchar) in TSQL are insufficient. in this case, using "CLR + Regular Expressions" is a good choice. Regular expressions seem very complex,, familiar with the metadata of regular expressions, you can skillfully and flexibly use regular expressions to complete complex TextMining work. During text

it together to see if this direction is feasible. I mainly want to know whether the full-text search, data mining, and recommendation engine technologies in your project can be applied to the health field ."Although this was Wu Yan's first attempt in the health field and the first time he thought about the application of full-text search, data

Gain more value from unstructured information. Study how a simple text mining application uses the UIMA SDK to build a text analysis engine to look for names in a document. Another UIMA component then writes the result to a table in the db2® database. This data is then used to use DB2 intelligent Miner to find strong associations between people who are often ment

(deep) Neural Networks (deep learning), NLP and Text MiningRecently flipped a bit about deep learning or common neural network in NLP and text mining aspects of the application of articles, including Word2vec, and then the key idea extracted out of the list, interested can be downloaded to see:Http://pan.baidu.com/s/1sjNQEfzI did not put some of my own ideas into

The rapid increase in massive heterogeneous Web Information Resources contains huge potential data. How to discover potentially valuable knowledge from vast Web resources becomes an urgent issue. People urgently need tools that can quickly and effectively discover resources and data on the Web to improve the efficiency of information retrieval and utilization on the Web. At present, most research on Web text minin
