Large data or emerging approaches to "depressive emotion recognition"

&http://www.aliyun.com/zixun/aggregation/37954.html ">nbsp; By hit the "Social network and data Mining" joint laboratory, the domestic data mining company "Hongbo know Micro" group of research and Development team, in the end of June, built based on social media data depression trend recognition model. The findings may be a new recognition method outside the clinical recognition of depression, people said.

According to public data, 63.5% of the suicides were depressed, but only 9% had visited psychiatric or psychiatric counseling before committing suicide. Depression identification model developers believe that using large data to identify individual depression tendencies and suicidal tendencies, or to save more depression-prone lives in time. The model is through the collection of Sina Micro-BO platform billion-level data, the use of natural language processing, time series, machine learning algorithms, to identify users of Weibo depression, the deadline has been identified by the users of depression, many people in the microblog said ready to commit suicide.

The presence of depression-prone microblogging users and ordinary users of the time there is a significant difference, this part of the group of people Bo Peak at 23 points, its nocturnal active degree than average users about 30% higher (figure II). The group's Twitter keywords are: death, depression, life, pain, suicide (see figure I). 60% were women, 40% were men, and women were slightly taller than men, and were matched by reports of two female microblog users who had "gone rice" and "Sienna Saina" to commit suicide due to depression.

The use of large data to intervene in the identification and treatment of depression is feasible, Weibo users disagree. Opponents of the Netizen "Sen elder brother-" think: "A thought in case I died Weibo will also be a stranger to turn out, publicly at, a statistical data, a candle, a good hundreds of forward, feel even the death of this thing is fucking no dignity." The starting point is good and how, the way is so rude, I do not feel that the PO Lord has tried to stand in the patient's perspective to understand the pain of melancholy. "With the support of the Netizen" La_prairie that ":" more care, less regret. "There are also neutral netizens think:" Large data for business, but also for non-profit boundless humanistic concern. For example, to the blogger to send excitation, positive energy content, real-time forward interference. ”

For the above controversy, the team said: The group has been engaged in mining and characterization of Sina Weibo's user profile since 2011, including industry profiling, disease portrayal, and emotional portrayal. will be in the future for some time, based on the continuous improvement of the emotional model, to increase the situation model and some figure image model, to the depressive tendency of the crowd (even other marginalized personality and some of the characteristics of the abnormal psychology in micro-blogging) to make more accurate judgments, for psychiatric disorders, social behavior of the early intervention to do data support.
