Project Ideas and Questions We'd Like to Answer

We have several possible ideas for the project:

• We propose to do a mapping of event to opinion. An event can be social or political in nature, which brings about a change in opinion or vice versa.

• We propose to analyze opinions from the perspective of associative sorting and social contagion. For example, to answer question on when does an opinion get pushed aside? i.e. centrality and periphery of opinions in the opinion-graph.

• We propose to construct a social graph, but instead of people, we put words as nodes. Using this social graph of words, we propose to analyze: (1) how co-occurrence with other words (associativity with other words) can influence meaning of words (for example, the word 'BP' was frequently 'associated' (co-occurred) with negative words during and after the Gulf-spill event), (2) how new words emerge in the graph (like ‘Google’), or a new part of speech (like 'googling'), (3) how meaning and usage of words like “LOL” changes with time - from meaning “laughing out loud”, to “whatever”.

• We propose to automatically create social graph on opinions from tweets, where nodes are people, links are follower/following relations, colors are attributes (positive or negative towards the entity we are interested in: like ‘Toyota’, ‘Ford’, etc)

Dataset
