Starting out NLP - Python + large data set

help you fix your problem NLTK is where you should start from (it's Python-based -- not sure why you're already thinking about parallelizing your processing at such an early stage... start with a more flexible experimental setup, is my advice). sqlite should be fine for a few GB -- if you need more advanced and standard SQL power you could consider postgresql.

Adding large numbers of properties in Core Data, crashing when starting from phone but not from Xcode

Adding large numbers of properties in Core Data, crashing when starting from phone but not from Xcode

around this issue Offload your file loading in a background thread and let the phone start up your main window and view. iOS will kill your app if you do not present a view in a timely manor (this is what you are seeing).
I have to do something like this for my xml -> CoreData converter code. I just present the user with a view notifying them of what is going on and a progress bar (I use https://github.com/matej/MBProgressHUD). something like:
code :
self.hud = [[MBProgressHUD alloc] initWithView:window];

// Set determinate mode
hud.mode = MBProgressHUDModeDeterminate;
hud.delegate = self;
hud.labelText = @"Converting Data File";
[self.window addSubview:hud];

// Show the HUD while the provided method executes in a new thread
[hud showWhileExecuting:@selector(convertToCoreDataStoreTask) onTarget:self withObject:nil animated:YES];
Efficient use of python objects to iterate over a large set of data calling python functions

wish help you to fix your issue If you want to do any operations on the data, there is no escaping having to create a large number of python objects. The chars, double, and int need to become immutable PyString, PyFloat, and PyInt objects respectively.
Since you are already writing C, you might as well create an iterator that returns a series of key/value/source tuples.

seems to work fine To prevent copying in Boost.Python, one can either:
Use policies to return internal references Allocate on the free store and use policies to have Python manage the object Allocate the Python object then extract a reference to the array within C++ Use a smart pointer to share ownership between C++ and Python

help you fix your problem For both the random and bucket searches, you can do a linear scan of the file and build a list of candidate results, replacing a candidate from the list if the list is full and a better candidate comes along.
For random selections, you simply calculate the odds of a candidate being in the list and use a random number to determine if the candidate gets placed in the list or not.
code :
import random
candidates = []
n = 0
with open(textFile) as inFile:
    for line in inFile:
        if valid_candidate(line): # use regex here
            n += 1
            if n <= x:
                candidates.append(line)
            else:
                i = random.randrange(n)
                if i < x:
                    candidates[i] = line
results = []
for line in candidates:
    analysisResult = analyze_the_match(line)
    results.append(analysisResult)
import bisect
candidates = []
n = 0
with open(textFile) as inFile:
    for line in inFile:
        n += 1
        if valid_candidate(line): # use regex here
            rank = get_rank(n) # use n to determine the bucket and assign a rank, lower numbers are higher rank
            bisect.insort(candidates, (rank, n, line))
results = []
for rank, n, line in candidates[:x]:
    analysisResult = analyze_the_match(line)
    results.append(analysisResult)

like below fixes the issue Python dict objects are unordered until Python 3.7
You can use OrderedDict:
code :
from collections import OrderedDict
import json


location_details = OrderedDict({
    "proxy_pass": "https://{{application_destination}}/abc/service$is_args$args",
    "host": "{{application_destination}}",
})

if "proxy_pass" in location_details:
    proxy_pass = location_details.pop('proxy_pass')
    location_details["set"] = "$backend " + proxy_pass
    location_details["proxy_pass"] = "$backend"

print(json.dumps(location_details, indent=4))
{
    "host": "{{application_destination}}", 
    "set": "$backend https://{{application_destination}}/abc/service$is_args$args", 
    "proxy_pass": "$backend"
}
from collections import OrderedDict
import json


location_details = OrderedDict({
    "proxy_pass": "https://{{application_destination}}/abc/service$is_args$args",
    "host": "{{application_destination}}",
})

if "proxy_pass" in location_details:
    proxy_pass = location_details.pop('proxy_pass')
    location_details["set"] = "$backend " + proxy_pass
    location_details["proxy_pass"] = "$backend"
    location_details.move_to_end('host')

print(json.dumps(location_details, indent=4))
{
    "set": "$backend https://{{application_destination}}/abc/service$is_args$args",
    "proxy_pass": "$backend",
    "host": "{{application_destination}}"
}
