Exploratory Study of Relationships among Statement Credibility, Context, and Semantic Similarity

In our work we investigate the relationship between semantic textual similarity and credibility of the individual sentence. For this purpose we performed an experiment to create a corpus of sentences with known credibility value. Then we calculated semantic similarity of each pair of sentences and tried to assess the credibility of a sentence using similar one. Performing comparison, we use idea to treat credibility as a probability distribution. By comparing the expected value of the credibility distribution with the results of the experiment, we evaluate the relationship of similarity relation with credibility.
