    This paper proposes a scheme for sentiment annotation. We show how the task can be made tractable by focusing on one of the many aspects of sentiment: sentiment as it is recorded in behaviour reports of people and their interactions. Together with a number of measures for supporting the reliable application of the scheme, this allows us to obtain sufficient to good agreement scores (in terms of Krippendorf's alpha) on three key dimensions: polarity, evaluated party and type of clause. Evaluation of the scheme is carried out through the annotation of an existing corpus of dialogue summaries (in English and Portuguese) by nine annotators. Our contribution to the field is twofold: (i) a reliable multi-dimensional annotation scheme for sentiment in behaviour reports; and (ii) an annotated corpus that was used for testing the reliability of the scheme and which is made available to the research community

    Are My Memory Changes Normal?

    This fact sheet discusses memory changes. As we age, our brains age right along with the rest of our bodies. Our reaction time may begin to slow as a result of aging, and we will continue to experience “mild forgetfulness” as a normal part of life. If your memory changes are greater, or these changes seem to be noticeably impacting your ability to carry on your normal day-to-day activities, these are indicators that it is time to be evaluated by a physician for MCI, dementia, or other cognitive problems. An accurate diagnosis of dementia will help you and your physician plan the best course of action for you, to keep your memory as sharp as possible as you get older

    Challenging your muscles makes for strong healthy muscles, and challenging your brain cells makes for a strong healthy brain. Build up your brain’s cognitive reserve – create a well-connected, high-capacity brain – through overall healthy behaviors (diet and exercise) and making mentally challenging activities part of your daily life. The more options your brain has to get its signals sent, the better able it is to handle areas of damage. A well-connected brain may be better able to delay or prevent diseases like Alzheimer’s
