For this example post #55 would be the one we would want judgments based on. You may need to read preceding posts to determent the context of the post, but sentiment should be based on post #55.
For all post other than Forums judge the overall sentiment of the entire post.
If a post is mostly reflecting the brand in a positive way, and only has a small portion that is negative, the post should be judged as positive. Likewise if the post is mostly negative with a small portion that is positive, it should be judged as negative. When it appears to be completely balanced select neutral.
If a post is not truly associated with the brand please select "This post is not about the brand".
If a post is links to another, make sure and judge based on the post not on the liked to article.
If a post is a sales or spam site, please judge this as neutral.
