EE359-Project

Project of SJTU EE359 Data Mining

Joint query for experts in certain fields on Stackoverflow.

Method

1. Using Louvain to cluster the raw graph
2. Correlate cluster to tags
3. Recommendation based on both global and local information
   1. Global: Using weighted page rank
   2. Local:
      1. Using biased random walk to extract neighbourhood.
      2. Combine Indegree and BFS to retrieve local recommendations

Current Results

Cluster result:

Local recommendationss:
Node index 1000, cluster index 5, 99 and 10.

TODO

1. improve BFS time
2. change PPR to random walk
3. vote to determine tags of clusters
4. test and experiments
5. report
6. reduce randomness of random walk
