How to take a row count of a list which is in word document?? If the same list is in excel I am able to take the count using aggregate operator but in word document it is not happening.
I recommend the answer from #awchisholm as it's the easiest solution. However, if you have several word documents this might become impractical.
In this case you can use the operator Loop Zip files to unzip the word document and look inside the for the file /word/document.xml and using RapidMiner's text functions (or Read XML) look for each instance of <w:p ...>...</w:p>, this represents a new line so you can count them from there.
There is also an xml doc in the unzipped directory called /docProps/app.xml you can read this in to find some meta information about the document such as number of words, characters & pages. Unfortunately I've found that unreliable for number of lines which is why I recommend using the <w:p> tag to search.
RapidMiner cannot easily read Word documents. You have to save the document as a text file and use the Read CSV operator to read the file.

Currently working on a Data Mining project using my own dataset I had found using Weka. The only issue is that taking my file from csv format and converting it into arff format is causing issues.
java.io.IOException: wrong number of values. Read 2, expected 5, Read Token[EOL], line 3
This is the error I am getting. I have browsed around online looking for similar issues and have tried removing all quotes and special characters that throw this exception. Every place I looked told me to remove special characters and I believe there are none left. The link to my dataset is here : https://docs.google.com/spreadsheets/d/1xqEe7MZE9SdKB_yvFSgWeSVYuDrq0b31Eu5oECNbGH0/edit#gid=1736568367&vpid=A1
This is the first three lines of my file where the first is the attribute names, file is separated by commas in note
Inequality Adjusted HPI Rank,Sub Region,Inequality Adjusted Life Expectancy,Inquality Adjusted Well being,Footprint
,Inequality adjusted HPI
1,1,73.1,6.9,2.5,48.2
2,6,65.17333333,5.487667631,1.390974448,45.97489063
If you open your file with a text editor, you will see that Footprint has quotes around it. Delete the quotes and you are good to go!
Weka is normally not that good in reading CSV files that include special characters, and ARFF files are normally easier to use. Therefore, in such cases, the easiest way is to convert your CSV file to an ARFF file using R ("RWeka" and "foreign" libraries can handle this conversion).
There is also another possibility. I was creating my CSV file and the header had a different number of elements compared to the rest of the data. So, check the header as well...!
How can I write ngrams extracted from Text to a new XLS or CSV file?
The process I created is shown below. I would like to know how to connect the Write Document utility and at which level. In the Main Process or in the Vector Creation? Which pipe goes where?
Screenshot Main Process:
Screenshot Vector Creation process:
Screenshot ngrams produced:
Screenshot Write Document operator:
I am using RapidMiner Studio 6.0.003 Community Edition
EDIT Solution:
There are two outputs from the Process Documents from Files operator. The top one is an example set and will correspond to the document vector generated by the operator. The bottom one is a word list that contains all the different words, including n-grams, that form the attributes within the document vector.
To write the word list to a file, you have to convert it to an example set using the WordList to Data operator. The example set that is produced can then be written to CSV or XLSX using the Write CSV or Write Excel operators.
I'm trying to write a csv file with the delimiter ctrl+a. I'm going to have to eventually write the file to hadoop and I'm unable to use a standard delimiter.
Currently I'm trying this:
writer = csv.writer(f, delimiter = "\u0001")
for item in aList:
writer.writerow(item)
f.close()
However, the outputted excel file doesn't appear to be written correctly...
Some rows are condensed into one block, while others will have one field in the first and then the rest condensed into the second block, etc.
Is the error where I'm setting up the writer object, or am I just not familiar with separating files this way?
You can try using the nonprinting "group separator" character, which can be represented in python code as '\035'
see http://www.asciitable.com/index/asciifull.gif for some other nonprinting characters if you need more.
It may be helpful to include more context about why you want to use nonstandard delimiter. And whether Excel parsing of the file is necessary, or just a quick check to see if the file might be parsed properly by the target system, Hadoop.
I have a set of csv files that are very simple to load into Stata using the -insheet- command. But they have very uninformative variable names. For each of these files, I also have a file of metadata consisting of two columns: the original (uninformative) variable names, and a description of what the variables actually mean. I'd like to use these metadata files to create variable labels, preferably without going through and typing up all the separate label commands or turning the metadata file into a dictionary for each file. It seems like there must be a quick way of loading the metadata file into Stata and looping through it to generate the label commands, but I don't know what it is. Any thoughts?
Ideally each line of the metadata is something like
varname1 "more interesting description"
in which case you can prefix each line with
label var
and then run the file as if it were a do-file using do. See the help for label. That is easy in a decent text editor, as for example searching for the start of each line and replacing it with label var (note the need for the space).
What could bite here includes:
You don't have double quotes " " as delimiters, in which case you need to insert them.
The extra information does not qualify as a variable label because it is more than 80 characters long. See help limits.
There are other ways to do this with Stata. You could write a program to read in the metadata and write out a do-file using file, but if this were my problem I would reach first for my text editor. (Most experienced Stata programmers use something else as well as doedit.)
I have a document that was converted from PDF to HTML for use on a company website to be referenced and indexed for search. I'm attempting to format the converted document to meet my needs and in doing so I am attempting to clean up some of the junk that was pulled over from when it was a PDF such as page numbers, headers, and footers. luckily all of these lines that need to be removed are in blocks of 4 lines unfortunately they are not exactly the same therefore cannot be removed with a simple literal replace. The lines contain numbers which are incremental as they correlate with the pages. How can I remove the following example from my html file.
Title<br>
10<br>
<hr>
<A name=11></a>Footer<br>
I've tried many different regular expression attempts but as my skill in that area is limited I can't find the proper syntax. I'm sure i'm missing something fairly easy as it would seem all I need is a wildcard replace for the two numbers in the code and the rest is literal.
any help is apprciated
The search & replace of npp is quite odd. I can't find newline charactes with regular expression, although the documentation says:
As of v4.9 the Simple find/replace (control+h) has changed, allowing the use of \r \n and \t in regex mode and the extended mode.
I updated to the last version, but it just doesn't work. Using the extended mode allows me to find newlines, but I can't specify wildcards.
However, you can use the macros to overcome this problems.
prepare a search that will find a unique passage (like Title<br>\r\n, here you can use the extended mode)
start recording a macro
press F3 to use your search
mark the four lines and delete them
stop recording the macro ... done!
Just replay it and it deletes what you wanted to delete.
If I have understood your request correctly this pattern matches your string:
Title<br>( ?)\n([0-9]+)<br>( ?)\n<hr>( ?)\n<A name=([0-9]+)></a>Footer<br>
I use the Regex Coach to try out complicated regex patterns. Other utilities are available.
edit
As I do not use Notepad++ I cannot be sure that this pattern will work for you. Apologies if that transpires to be the case. (I'm a TextPad man myself, and it does work with that tool).
