1.2 Input format

Each user's tweets are put in a file. The file is named by the user's user_id. Each line in the file has format: ... where wj is index of a word in tweet vocabulary. The is used for dividing tweets into batches for cross validation, or for labeling (part of) the tweets by pre-defined topics in semi-supervised learning (see STwitterLDA below)
All users' tweet files are put in "users" folder
Tweet vocabulary is put in "vocabulary.txt" file
The "users" folder and the "vocabulary.txt" file are put in "tweet" folder
The path to "tweet" folder is input for the program

All output files are put in a given output folder
File "coinBias.csv" contains (global) bias of users toward choosing words from background topic. Format:
File "likelihood-perplexity.csv" contains likelihood and perplexity of the model
File "tweetTopics.csv" contains topics' word distribution. Each line in the file is a topic. Format of a line: <topic_number>,<p_0>,...,<p_N> where p_j is probability of the j-th word in the tweet vocabulary
File "tweetTopicTopTweets.csv" contains top 20 tweets of the topic. Format: <topic_0> ,<tweet_id>, ... ,<tweet_id>, <topic_1> ,<tweet_id>, ... ,<tweet_id>, ...
File "tweetTopicTopWords.csv" contains top 20 words of the topic. Format: <topic_0> ,, ... ,, <topic_1> ,, ... ,, ...
File "userTopics.csv" contains users' topic distribution. Each line in the file is a user. Format of a line: <user_id>,<p_0>,...,<p_N> where p_k is probability of the k-th topic

STwitterLDA: TwitterLDA with semi-supervised learning: part of tweets are labeled by pre-defined topics. The in tweets input are topic_id or -1 if the tweets are not labeled.
NBTwitterLDA: TwitterLDA without background topic.

It is not just what we say, but how we say them: LDA-based behavior-topic model, Qiu et al., SDM 2013

Each user's tweets are put in a file. The file is named by the user's user_id. Each line in the file has format: ... where wj is index of a word in tweet vocabulary. The is used for dividing tweets into batches for cross validation
Each user's retweets are put in a file with the same format with the tweet files
All users' tweet files are put in "tweets" folder, and all users' retweets are put in "retweets" folder
Tweet vocabulary is put in "vocabulary.txt" file
The "tweets", "retweets" folders and the "vocabulary.txt" file are put in "data" folder
The path to the "data" folder is input for the program

All output files are put in a given output folder
File "coinBias.csv" contains (global) bias of users toward choosing words from background topic. Format:
File "likelihood-perplexity.csv" contains likelihood and perplexity of the model
File "behaviorBias.csv" contains (global) bias of users toward tweeting or retweeting specific to topics. Each line is a topic. Format: <topic_id>
File "tweetTopics.csv" contains topics' word distribution. Each line in the file is a topic. Format of a line: <topic_number>,<p_0>,...,<p_N> where p_j is probability of the j-th word in the tweet vocabulary
File "tweetTopicTopTweets.csv" contains top 20 tweets of the topic. Format: <topic_0> ,<tweet_id>, ... ,<tweet_id>, <topic_1> ,<tweet_id>, ... ,<tweet_id>, ...
File "tweetTopicTopWords.csv" contains top 20 words of the topic. Format: <topic_0> ,, ... ,, <topic_1> ,, ... ,, ...
File "userTopics.csv" contains users' topic distribution. Each line in the file is a user. Format of a line: <user_id>,<p_0>,...,<p_N> where p_k is probability of the k-th topic

Generalized Topic Model ================================== 3.1 Reference ============= Modeling Topics and Behaviors of Microbloggers: An Integrated Approach, Hoang et al., Preprint

Each user's tweets are put in a file. The file is named by the user's user_id. Each line in the file has format: ... where wj is index of a word in tweet vocabulary. The is used for dividing tweets into batches for cross validation
All users' tweet files are put in "users" folder
Tweet vocabulary is put in "vocabulary.txt" file
The "users" folder and the "vocabulary.txt" file are put in "tweets" folder
For each type of behavior (e.g., hashtag, mention), the users' behavior adoptions are put in "user.txt" file. Each line is a user. Format of a line: <user_id><b1:number of adoptions of b1>...<bM:number of adoptions of bM> where bj is index of the behavior in the behavior vocabulary. The behavior vocabulary is put in "vocabulary.txt" file. The "user.txt" and "vocabulary.txt" files are put in folder named by behavior type
"tweets" and all behavior folders are put in "data" folder
The path to the "data" folder is input for the program

All output files are put in a given output folder
File "likelihood-perplexity.csv" contains likelihood and perplexity of the model
File "tweetTopics.csv" contains topics' word distribution. Each line in the file is a topic. Format of a line: <topic_number>,<p_0>,...,<p_N> where p_j is probability of the j-th word in the tweet vocabulary
File "tweetTopicTopTweets.csv" contains top 20 tweets of the topic. Format: <topic_0> ,<tweet_id>, ... ,<tweet_id>, <topic_1> ,<tweet_id>, ... ,<tweet_id>, ...
File "tweetTopicTopWords.csv" contains top 20 words of the topic. Format: <topic_0> ,, ... ,, <topic_1> ,, ... ,, ...
For each type of behavior, topics' behavior distribution and top behaviors are put in "<behavior_name>Topics.csv" and "<behavior_name>TopicTopWords.csv" similar to topics' word distribution and top words files.
File "userRealms.csv" contains users' bias toward realms and their realm distribution. Each line in the file is a user. Format of a line: <user_id>,,,<p_0>,...,<p_N> where p_r is probability of the r-th realm
File "userTopics.csv" contains users' topic distribution. Each line in the file is a user. Format of a line: <user_id>,<p_0>,...,<p_N> where p_k is probability of the k-th topic
