1. Data 받아오기
1) selenuim을 이용하여 웹페이지에서 데이터를 검색
2) 원하는 URL 입력받는다
3) headless하게 구현하기 위해 chrome option 적용하여 driver 생성
4) naverNews는 댓글 영역 하단 부 '더보기'를 지속적으로 눌러줘야하므로
driver의 find_element_by_css_selector함수로 해당 class인
u_cbox_btn_more을 페이지가 끝날 때까지 돌림
5) 위의 과정에서 얻은 페이지 소스를 beautifulSoup을 이용하여, find_all을 통해 {사용자ID, 댓글, 작성시간}의 데이터를 각각 raw하게 뽑음. (naverNews의 제한적인 특징으로 사용자ID 뒤 4자리는 비공개처리됨)
2. 사용할 DataSet으로 가공
1) 리스트 형태로 각각 nicknames(사용자ID), comments(댓글), times(작성시간)을 뽑아냄
2) 세 리스트에서 짝을 이루는 쌍을 dictionary형태로 {사용자ID, 댓글, 작성시간} 다음과 같이 저장
3) 저장된 dictionary list(info_dic)을 최종 결과 리스트인 naverNewsList에 저장한다.
3. 함수 구현
1) KEYWORD 기반 검색 기능
2) 가장 자주 나온 단어 검색 기능
3) ID 기반 검색 기능
4) 시간 대별 검색 기능
등 여러 함수 구현 예정
=> 수정사항
data를 get하여 정제하는 파일을 모듈로 분리해 내어 list형태로 저장된 데이터셋을 반환하여
main 에서 사용할 수 있도록 한다. 이 후 main에서 리스트를 받아와 url을 입력받아 데이터를
받아오는 방식으로 사용한다. 이 후, keyword기반, id기반, 시간대 기반 검색 함수를 구현하였고
시간대별 검색 함수의 기능 보강과 가장 자주 나온 단어 검색 기능을 추가 구현할 예정이다.
* 4차 수정사항
기존파일의 분리 관리 시, import관련 오류 문제 해결 완료(하나의 파일로 관리)
사용자 UI의 틀을 구축해놓았고, 곧바로 함수별 추가 세부 구현 예정
* 5차 수정사항
1) 네이버 댓글공간엑서 받아온 날짜 정보를 YYYY-MM-DD형식으로 바꿈. ('방금 전, 몇 분 전, 몇 시간 전, 몇 일 전'의 경우를 처리하기 위해 dateTime과 timeDelta 모듈을 활용하여
현재 날짜를 기준으로 계산하여 YYYY-MM-DD로 저장될 수 있도록
코드 추가)
2) 시간대별로 (시작시간, 끝시간)을 입력하여 그 시간에 해당하는 기사를 출력해주는 함수 구현
가장 자주 많이 나온 단어 검색과 MATPLOTLIB을 활용한 시각적 표현 구현 예정
* 6차 수정사항
konlpy를 활용한 명사 추출 및 단어 빈도수가 많으 순대로 사용자가 입력한 limit만큼 출력해주는 함수 구현 완료

Higher level content negotiation based on [negotiator](https://www.npmjs.com/package/negotiator).
Extracted from [koa](https://www.npmjs.com/package/koa) for general use.
In addition to negotiator, it allows:
- Allows types as an array or arguments list, ie `(['text/html', 'application/json'])`
as well as `('text/html', 'application/json')`.
- Allows type shorthands such as `json`.
- Returns `false` when no types match
- Treats non-existent headers as `*`
## Installation
This is a [Node.js](https://nodejs.org/en/) module available through the
[npm registry](https://www.npmjs.com/). Installation is done using the
[`npm install` command](https://docs.npmjs.com/getting-started/installing-npm-packages-locally):
```sh
$ npm install accepts
```
## API
<!-- eslint-disable no-unused-vars -->
```js
var accepts = require('accepts')
```
### accepts(req)
Create a new `Accepts` object for the given `req`.
#### .charset(charsets)
Return the first accepted charset. If nothing in `charsets` is accepted,
then `false` is returned.
#### .charsets()
Return the charsets that the request accepts, in the order of the client's
preference (most preferred first).
#### .encoding(encodings)
Return the first accepted encoding. If nothing in `encodings` is accepted,
then `false` is returned.
#### .encodings()
Return the encodings that the request accepts, in the order of the client's
preference (most preferred first).
#### .language(languages)
Return the first accepted language. If nothing in `languages` is accepted,
then `false` is returned.
#### .languages()
Return the languages that the request accepts, in the order of the client's
preference (most preferred first).
#### .type(types)
Return the first accepted type (and it is returned as the same text as what
appears in the `types` array). If nothing in `types` is accepted, then `false`
is returned.
The `types` array can contain full MIME types or file extensions. Any value
that is not a full MIME types is passed to `require('mime-types').lookup`.
#### .types()
Return the types that the request accepts, in the order of the client's
preference (most preferred first).
## Examples
### Simple type negotiation
This simple example shows how to use `accepts` to return a different typed
respond body based on what the client wants to accept. The server lists it's
preferences in order and will get back the best match between the client and
server.
```js
var accepts = require('accepts')
var http = require('http')
function app (req, res) {
var accept = accepts(req)
// the order of this list is significant; should be server preferred order
switch (accept.type(['json', 'html'])) {
case 'json':
res.setHeader('Content-Type', 'application/json')
res.write('{"hello":"world!"}')
break
case 'html':
res.setHeader('Content-Type', 'text/html')
res.write('<b>hello, world!</b>')
break
default:
// the fallback is text/plain, so no need to specify it above
res.setHeader('Content-Type', 'text/plain')
res.write('hello, world!')
break
}
res.end()
}
http.createServer(app).listen(3000)
```
You can test this out with the cURL program:
```sh
curl -I -H'Accept: text/html' http://localhost:3000/
```

![bignumber.js](https://raw.githubusercontent.com/MikeMcl/bignumber.js/gh-pages/bignumberjs.png)
A JavaScript library for arbitrary-precision decimal and non-decimal arithmetic.
[![Build Status](https://travis-ci.org/MikeMcl/bignumber.js.svg)](https://travis-ci.org/MikeMcl/bignumber.js)
<br />
## Features
- Integers and decimals
- Simple API but full-featured
- Faster, smaller, and perhaps easier to use than JavaScript versions of Java's BigDecimal
- 8 KB minified and gzipped
- Replicates the `toExponential`, `toFixed`, `toPrecision` and `toString` methods of JavaScript's Number type
- Includes a `toFraction` and a correctly-rounded `squareRoot` method
- Supports cryptographically-secure pseudo-random number generation
- No dependencies
- Wide platform compatibility: uses JavaScript 1.5 (ECMAScript 3) features only
- Comprehensive [documentation](http://mikemcl.github.io/bignumber.js/) and test set
![API](https://raw.githubusercontent.com/MikeMcl/bignumber.js/gh-pages/API.png)
If a smaller and simpler library is required see [big.js](https://github.com/MikeMcl/big.js/).
It's less than half the size but only works with decimal numbers and only has half the methods.
It also does not allow `NaN` or `Infinity`, or have the configuration options of this library.
See also [decimal.js](https://github.com/MikeMcl/decimal.js/), which among other things adds support for non-integer powers, and performs all operations to a specified number of significant digits.
## Load
The library is the single JavaScript file *bignumber.js* (or minified, *bignumber.min.js*).
Browser:
```html
<script src='path/to/bignumber.js'></script>
```
[Node.js](http://nodejs.org):
```bash
$ npm install --save bignumber.js
```
```javascript
var BigNumber = require('bignumber.js');
```
ES6 module (*bignumber.mjs*):
```javascript
//import BigNumber from 'bignumber.js';
import {BigNumber} from 'bignumber.js';
```
AMD loader libraries such as [requireJS](http://requirejs.org/):
```javascript
require(['bignumber'], function(BigNumber) {
// Use BigNumber here in local scope. No global BigNumber.
});
```
## Use
*In all examples below, `var`, semicolons and `toString` calls are not shown.
If a commented-out value is in quotes it means `toString` has been called on the preceding expression.*
The library exports a single function: `BigNumber`, the constructor of BigNumber instances.
It accepts a value of type Number, String or BigNumber,
```javascript
x = new BigNumber(123.4567)
y = BigNumber('123456.7e-3')
z = new BigNumber(x)
x.isEqualTo(y) && y.isEqualTo(z) && x.isEqualTo(z) // true
```
and a base can be specified.
```javascript
a = new BigNumber(1011, 2) // "11"
b = new BigNumber('zz.9', 36) // "1295.25"
c = x.plus(y) // "1306.25"
```
Note that a BigNumber is created from a Number's decimal `toString()` value not from its underlying binary value. If the latter is required, then pass the Number's `toString(2)` value and specify base 2.
```javascript
new BigNumber(Number.MAX_VALUE.toString(2), 2)
```
If the limited precision of Number values is not well understood, **it is recommended to pass String values rather than Number values** to avoid a potential loss of precision.
```javascript
// Precision loss from using numeric literals with more than 15 significant digits.
new BigNumber(1.0000000000000001); // '1'
new BigNumber(88259496234518.57); // '88259496234518.56'
new BigNumber(99999999999999999999); // '100000000000000000000'
// Precision loss from using numeric literals outside the range of Number values.
new BigNumber(2e+308); // 'Infinity'
new BigNumber(1e-324); // '0'
// Precision loss from the unexpected result of arithmetic with Number values.
new BigNumber(0.7 + 0.1); // '0.7999999999999999'
```
A BigNumber is immutable in the sense that it is not changed by its methods.
```javascript
0.3 - 0.1 // 0.19999999999999998
x = new BigNumber(0.3)
x.minus(0.1) // "0.2"
x // "0.3"
```
The methods that return a BigNumber can be chained.
```javascript
x.dividedBy(y).plus(z).times(9)
x.times('1.23456780123456789e+9').plus(9876.5432321).dividedBy('4444562598.111772').integerValue()
```
Some of the longer method names have a shorter alias.
```javascript
x.squareRoot().dividedBy(y).exponentiatedBy(3).isEqualTo( x.sqrt().div(y).pow(3) ) // true
x.modulo(y).multipliedBy(z).eq( x.mod(y).times(z) ) // true
```
As with JavaScript's Number type, there are `toExponential`, `toFixed` and `toPrecision` methods
```javascript
x = new BigNumber(255.5)
x.toExponential(5) // "2.55500e+2"
x.toFixed(5) // "255.50000"
x.toPrecision(5) // "255.50"
x.toNumber() // 255.5
```
and a base can be specified for `toString`.
```javascript
x.toString(16) // "ff.8"
```
There is also a `toFormat` method which may be useful for internationalisation
```javascript
y = new BigNumber('1234567.898765')
y.toFormat(2) // "1,234,567.90"
```
The maximum number of decimal places of the result of an operation involving division (i.e. a division, square root, base conversion or negative power operation) is set using the `config` method of the `BigNumber` constructor.
The other arithmetic operations always give the exact result.
```javascript
BigNumber.config({ DECIMAL_PLACES: 10, ROUNDING_MODE: 4 })
x = new BigNumber(2);
y = new BigNumber(3);
z = x.dividedBy(y) // "0.6666666667"
z.squareRoot() // "0.8164965809"
z.exponentiatedBy(-3) // "3.3749999995"
z.toString(2) // "0.1010101011"
z.multipliedBy(z) // "0.44444444448888888889"
z.multipliedBy(z).decimalPlaces(10) // "0.4444444445"
```
There is a `toFraction` method with an optional *maximum denominator* argument
```javascript
y = new BigNumber(355)
pi = y.dividedBy(113) // "3.1415929204"
pi.toFraction() // [ "7853982301", "2500000000" ]
pi.toFraction(1000) // [ "355", "113" ]
```
and `isNaN` and `isFinite` methods, as `NaN` and `Infinity` are valid `BigNumber` values.
```javascript
x = new BigNumber(NaN) // "NaN"
y = new BigNumber(Infinity) // "Infinity"
x.isNaN() && !y.isNaN() && !x.isFinite() && !y.isFinite() // true
```
The value of a BigNumber is stored in a decimal floating point format in terms of a coefficient, exponent and sign.
```javascript
x = new BigNumber(-123.456);
x.c // [ 123, 45600000000000 ] coefficient (i.e. significand)
x.e // 2 exponent
x.s // -1 sign
```
For advanced usage, multiple BigNumber constructors can be created, each with their own independent configuration which applies to all BigNumber's created from it.
```javascript
// Set DECIMAL_PLACES for the original BigNumber constructor
BigNumber.config({ DECIMAL_PLACES: 10 })
// Create another BigNumber constructor, optionally passing in a configuration object
BN = BigNumber.clone({ DECIMAL_PLACES: 5 })
x = new BigNumber(1)
y = new BN(1)
x.div(3) // '0.3333333333'
y.div(3) // '0.33333'
```
For futher information see the [API](http://mikemcl.github.io/bignumber.js/) reference in the *doc* directory.
## Test
The *test/modules* directory contains the test scripts for each method.
The tests can be run with Node.js or a browser. For Node.js use
$ npm test
or
$ node test/test
To test a single method, use, for example
$ node test/methods/toFraction
For the browser, open *test/test.html*.
## Performance
See the [README](https://github.com/MikeMcl/bignumber.js/tree/master/perf) in the *perf* directory.
## Build
For Node, if [uglify-js](https://github.com/mishoo/UglifyJS2) is installed
npm install uglify-js -g
then
npm run build
will create *bignumber.min.js*.
A source map will also be created in the root directory.

Utility to parse a string bytes (ex: `1TB`) to bytes (`1099511627776`) and vice-versa.
## Installation
This is a [Node.js](https://nodejs.org/en/) module available through the
[npm registry](https://www.npmjs.com/). Installation is done using the
[`npm install` command](https://docs.npmjs.com/getting-started/installing-npm-packages-locally):
```bash
$ npm install bytes
```
## Usage
```js
var bytes = require('bytes');
```
#### bytes.format(number value, [options]): string｜null
Format the given value in bytes into a string. If the value is negative, it is kept as such. If it is a float, it is
rounded.
**Arguments**
| Name | Type | Description |
|---------|----------|--------------------|
| value | `number` | Value in bytes |
| options | `Object` | Conversion options |
**Options**
| Property | Type | Description |
|-------------------|--------|-----------------------------------------------------------------------------------------|
| decimalPlaces | `number`｜`null` | Maximum number of decimal places to include in output. Default value to `2`. |
| fixedDecimals | `boolean`｜`null` | Whether to always display the maximum number of decimal places. Default value to `false` |
| thousandsSeparator | `string`｜`null` | Example of values: `' '`, `','` and `.`... Default value to `''`. |
| unit | `string`｜`null` | The unit in which the result will be returned (B/KB/MB/GB/TB). Default value to `''` (which means auto detect). |
| unitSeparator | `string`｜`null` | Separator to use between number and unit. Default value to `''`. |
**Returns**
| Name | Type | Description |
|---------|------------------|-------------------------------------------------|
| results | `string`｜`null` | Return null upon error. String value otherwise. |
**Example**
```js
bytes(1024);
// output: '1KB'
bytes(1000);
// output: '1000B'
bytes(1000, {thousandsSeparator: ' '});
// output: '1 000B'
bytes(1024 * 1.7, {decimalPlaces: 0});
// output: '2KB'
bytes(1024, {unitSeparator: ' '});
// output: '1 KB'
```
#### bytes.parse(string｜number value): number｜null
Parse the string value into an integer in bytes. If no unit is given, or `value`
is a number, it is assumed the value is in bytes.
Supported units and abbreviations are as follows and are case-insensitive:
* `b` for bytes
* `kb` for kilobytes
* `mb` for megabytes
* `gb` for gigabytes
* `tb` for terabytes
* `pb` for petabytes
The units are in powers of two, not ten. This means 1kb = 1024b according to this parser.
**Arguments**
| Name | Type | Description |
|---------------|--------|--------------------|
| value | `string`｜`number` | String to parse, or number in bytes. |
**Returns**
| Name | Type | Description |
|---------|-------------|-------------------------|
| results | `number`｜`null` | Return null upon error. Value in bytes otherwise. |
**Example**
```js
bytes('1KB');
// output: 1024
bytes('1024');
// output: 1024
bytes(1024);
// output: 1KB
```

Create and parse HTTP `Content-Disposition` header
## Installation
```sh
$ npm install content-disposition
```
## API
<!-- eslint-disable no-unused-vars -->
```js
var contentDisposition = require('content-disposition')
```
### contentDisposition(filename, options)
Create an attachment `Content-Disposition` header value using the given file name,
if supplied. The `filename` is optional and if no file name is desired, but you
want to specify `options`, set `filename` to `undefined`.
<!-- eslint-disable no-undef -->
```js
res.setHeader('Content-Disposition', contentDisposition('∫ maths.pdf'))
```
**note** HTTP headers are of the ISO-8859-1 character set. If you are writing this
header through a means different from `setHeader` in Node.js, you'll want to specify
the `'binary'` encoding in Node.js.
#### Options
`contentDisposition` accepts these properties in the options object.
##### fallback
If the `filename` option is outside ISO-8859-1, then the file name is actually
stored in a supplemental field for clients that support Unicode file names and
a ISO-8859-1 version of the file name is automatically generated.
This specifies the ISO-8859-1 file name to override the automatic generation or
disables the generation all together, defaults to `true`.
- A string will specify the ISO-8859-1 file name to use in place of automatic
generation.
- `false` will disable including a ISO-8859-1 file name and only include the
Unicode version (unless the file name is already ISO-8859-1).
- `true` will enable automatic generation if the file name is outside ISO-8859-1.
If the `filename` option is ISO-8859-1 and this option is specified and has a
different value, then the `filename` option is encoded in the extended field
and this set as the fallback field, even though they are both ISO-8859-1.
##### type
Specifies the disposition type, defaults to `"attachment"`. This can also be
`"inline"`, or any other value (all values except inline are treated like
`attachment`, but can convey additional information if both parties agree to
it). The type is normalized to lower-case.
### contentDisposition.parse(string)
<!-- eslint-disable no-undef, no-unused-vars -->
```js
var disposition = contentDisposition.parse('attachment; filename="EURO rates.txt"; filename*=UTF-8\'\'%e2%82%ac%20rates.txt')
```
Parse a `Content-Disposition` header string. This automatically handles extended
("Unicode") parameters by decoding them and providing them under the standard
parameter name. This will return an object with the following properties (examples
are shown for the string `'attachment; filename="EURO rates.txt"; filename*=UTF-8\'\'%e2%82%ac%20rates.txt'`):
- `type`: The disposition type (always lower case). Example: `'attachment'`
- `parameters`: An object of the parameters in the disposition (name of parameter
always lower case and extended versions replace non-extended versions). Example:
`{filename: "€ rates.txt"}`
## Examples
### Send a file for download
```js
var contentDisposition = require('content-disposition')
var destroy = require('destroy')
var fs = require('fs')
var http = require('http')
var onFinished = require('on-finished')
var filePath = '/path/to/public/plans.pdf'
http.createServer(function onRequest (req, res) {
// set headers
res.setHeader('Content-Type', 'application/pdf')
res.setHeader('Content-Disposition', contentDisposition(filePath))
// send file
var stream = fs.createReadStream(filePath)
stream.pipe(res)
onFinished(res, function () {
destroy(stream)
})
})
```
## Testing
```sh
$ npm test
```

Create and parse HTTP Content-Type header according to RFC 7231
## Installation
```sh
$ npm install content-type
```
## API
```js
var contentType = require('content-type')
```
### contentType.parse(string)
```js
var obj = contentType.parse('image/svg+xml; charset=utf-8')
```
Parse a content type string. This will return an object with the following
properties (examples are shown for the string `'image/svg+xml; charset=utf-8'`):
- `type`: The media type (the type and subtype, always lower case).
Example: `'image/svg+xml'`
- `parameters`: An object of the parameters in the media type (name of parameter
always lower case). Example: `{charset: 'utf-8'}`
Throws a `TypeError` if the string is missing or invalid.
### contentType.parse(req)
```js
var obj = contentType.parse(req)
```
Parse the `content-type` header from the given `req`. Short-cut for
`contentType.parse(req.headers['content-type'])`.
Throws a `TypeError` if the `Content-Type` header is missing or invalid.
### contentType.parse(res)
```js
var obj = contentType.parse(res)
```
Parse the `content-type` header set on the given `res`. Short-cut for
`contentType.parse(res.getHeader('content-type'))`.
Throws a `TypeError` if the `Content-Type` header is missing or invalid.
### contentType.format(obj)
```js
var str = contentType.format({type: 'image/svg+xml'})
```
Format an object into a content type string. This will return a string of the
content type for the given object with the following properties (examples are
shown that produce the string `'image/svg+xml; charset=utf-8'`):
- `type`: The media type (will be lower-cased). Example: `'image/svg+xml'`
- `parameters`: An object of the parameters in the media type (name of the
parameter will be lower-cased). Example: `{charset: 'utf-8'}`
Throws a `TypeError` if the object contains an invalid type or parameter names.
