text-processing

问题 I'm currently working on a project, where I want to extract emotion from text. As I'm using conceptnet5 (a semantic network), I can't however simply prefix words in a sentence that contains a negation-word, as those words would simply not show up in conceptnet5's API. Here's an example: The movie wasn't that good. Hence, I figured that I could use wordnet's lemma functionality to replace adjectives in sentences that contain negation-words like (not, ...). In the previous example, the

问题 This self-answered question addresses the scenario originally described in Increment version number in file: A version number embedded in a text file is to be incremented. Sample text-file content: nuspec{ id = XXX; version: 0.0.30; title: XXX; For instance, I want embedded version number 0.0.30 updated to 0.0.31 . The line of interest can be assumed to match the following regex: ^\s+version: (.+);$ Note hat the intent is not to replace the version number with a fixed new version, but to

问题 I'm using the following two methods to calculate a sample string's rendered width for a set font-type and size: font = ImageFont.truetype("/usr/share/fonts/truetype/dejavu/DejaVuSans.ttf", 14) sample = "Lorem ipsum dolor sit amet, partem periculis an duo, eum lorem paulo an, mazim feugiat lobortis sea ut.

问题 I am trying to write an AWK script to summarize data on a large text file. The order of the resulting data is important so i can't use sort. I have tried different variations of FNR==NR but haven't had any luck Input file Height 3.5 Weight 12.3 Age 23 : : Height 4.5 Weight 15.5 Age 31 : : Expected Output Height 3.5 4.5 Weight 12.3 15.5 Age 23 31 回答1: With awk: awk '{a[$1]=a[$1] FS $2} END{for(i in a) print i a[i]}' file Output: Weight 12.3 15.5 Height 3.5 4.5 : Age 23 31 Derived from: how to

问题 I know that awk can be used to print only certain words from the output.For example dpkg -l|awk '{print $2}' would print 2nd word from the output of dpkg -l . What I want to do is, print every word after a given word.My command looks like this awk '{printf "%-40s %s\n", $1, $n}' Rather than printing all the words with $n or $0 , I would like to print every word that comes after, say 5th character. How can I do this? EDIT : my complete command is bind -P|grep "can be found"|sort|awk '{printf "

问题 I have a Bash variable, $word , which is sometimes a word or sentence, e.g.: word="tiger" Or: word="This is a sentence." How can I make a new Bash variable which is equal to only the first letter found in the variable? E.g., the above would be: echo $firstletter t Or: echo $firstletter T 回答1: initial="$(echo $word | head -c 1)" Every time you say "first" in your problem description, head is a likely solution. 回答2: word="tiger" firstletter=${word:0:1} 回答3: word=something first=${word::1} 回答4:

问题 I have a CSV file through which I am trying to load data into my SQL table containing 2 columns. I have 2 columns and the data is separated by commas, which identify the next field. The second column contains text and some commas in that text. Because of the extra commas I am not able to load data into my SQL table as it looks like it has extra columns. I have millions of rows of data. How can I remove these extra commas? Data: Number Address "12345" , "123 abc street, Unit 345" "67893" ,
