To fully load the listings here, we need to scroll the page down to the bottom continuously.Paste the URL into the "Website" box and click "Save URL" to move on.Click "+ Task" to start a task using Advanced Mode.Unlike scraping with Python, we don’t need to start with applying for API, simply inputting the URL into Octoparse will do. Or we could apply other libraries like pandas, numpy and re to further clean the data. We could write the data into a spreadsheet and set the delimiter as “ ” to separate the fields. The first field is the username, the second field is location and the last field is the tweet. Different fields are separated by two semi-colons “ ”. Here we will search all tweets related to the keyword “Big data” and start our extraction with Stream.Įach line of data is information from one tweet. Now we only need a few more steps to run and extract the information. Next, we could submit our key and secret using OAuthHandler we called from Tweepy. Therefore, we should consider using another character encoding such as UTF-8 instead of the default Unicode character encoding. For some of the information such as tweets, username, time zone, there would be words in other languages. We could scrape information such as tweets, location, username, user id, followers count, friends count, favourites count and time zone. Here we will create a class inheriting from StreamListener to modify what kind of fields we need to scrape from Twitter. Then fill in the keys and secrets you applied through the previous link. StreamListener could help us modify the fields we need from each tweet.
OAuthHandler could help us submit our keys and secrets to Twitter. The stream could help us run and extract the tweets.
It contains many useful functions and classes to handle various implementation details. Tweepy is an open-source package to access Twitter API. JSON is a build-in package which could be applied to manipulate JSON data. We will use two libraries to build the crawler, json and tweepy. Now that we have the API, we could start to build our Twitter crawler. After applying for the API, we could get 4 lines of code, which are API key, API secret key, Access token, and Access token secret. To scrape Twitter with Python, we will first need to apply for a Twitter API through this link. In this passage, we will present a demo of scraping Tweets using these two methods. Generally, they are divided into 2 factions: coding and tools.
#Octoparse vs web scraper software#
People begin to develop or use a variety of different software to achieve their goal. Web scraping has become a widely used technique for gathering and extracting data from websites.
