Reading Files

First we need to import metaknowledge like we saw in lesson 1.



In [1]:

    
import metaknowledge as mk

we only need metaknowledge for now so no need to import everything

The files from the Web of Science (WOS) can be loaded into a RecordCollections by creating a RecordCollection with the path to the files given to it as a string.



In [2]:

    
RC = mk.RecordCollection("savedrecs.txt")
repr(RC)









    Out[2]:





'savedrecs'

You can also read a whole directory, in this case it is reading the current working directory



In [3]:

    
RC = mk.RecordCollection(".")
repr(RC)









    Out[3]:





'files-from-.'

metaknowledge can detect if a file is a valid WOS file or not and will read the entire directory and load only those that have the right header. You can also tell it to only read a certain type of file, by using the extension argument.



In [4]:

    
RC = mk.RecordCollection(".", extension = "txt")
repr(RC)









    Out[4]:





'txt-files-from-.'

Now you have a RecordCollection composed of all the WOS records in the selected file(s).



In [5]:

    
print("RC is a " + str(RC))









    



RC is a Collection of 32 records

You might have noticed I used two different ways to display the RecordCollection. repr(RC) will give you where metaknowledge thinks the collection came from. While str(RC) will give you a nice string containing the number of Records.
