Overview

[INTRO] Regarding collaboration, forming teams that perform well is an important problem because…. Social elements is key to the problem because…. It's easy to form the network, and research shows links between social elements and team performance. However these are not complete because… A novel approach is… It needs a large dataset, so the iMDB is ideal because… The analisys is non-trivial because of_. We found our model can improve the ways we currently understand and predict team success in this context, and our contributions are …, the rest of the work is organized as…

[FUNDAMENTALS] The concepts from SNA mentioned in this work are (graph, bipartite graph, one-mode-graph, topological metrics, clique, node contraction). Using SNA a bipartite network can be projected into a one-mode network. Special handling is needed when using SNA metrics in projections from a bipartite graph. We can access social characteristics from cliques in a social graph by aggregating metrics from clique's nodes or by getting metrics from the clique's contracted node. IMDb describes movie production generously, but has many amateur movies that just add noise. Its movie co-authorship data is directly mappable to a bipartite graph between movies and agents. iMDB also provides these extra information from movies with are known to be correlated to movie success. The ML concepts mentioned in this work are….

[RELATED WORK] These works find how to better form teams, these works find how to predict team success, both do it with a different approach. These works use a similar approach, but they have these limitations we don't. Our results alone aren't better than previous work but can be combined with other predictive models to previous works to improve them.

[MODEL] This is our model for a social network of movie producers. This is how we filter the dataset. This is how we define movie success. This is how we group movies based on success, and here is the characterization of the groups. Tis is how we define topological features from teams (based on previous studies we use these other features for control), and here is the characterization from such features. Here is how features interact. Here is the final ML model we created for predicting movie success.

[ANALYSIS] We proof that our prediction model works because of…. We know that our features are adequate for prediction because…. These were the experiments we made and its setup characteristics, and these are the results. These are the meanings for all these results.

[CONCLUSION] Here is a summary of what we did, and here is a summary of the new things we found. Here is how the field is changed in result of our work. Here is the reasons we think are behind what we found. Here are the greatest difficulties faced, and how we managed them. Here is how we think the work should continue. Here are the publications generated from this work.
