With the rise of social media, millions people are routinely expressing their moods, feelings, and daily struggles with mental health issues on media platforms like Twitter. Unlike traditional observational cohort studies conducted through questionnaires self-reported surveys, we explore reliable detection clinical depression from tweets obtained unobtrusively. Based analysis crawled users depressive symptoms in Twitter profiles, demonstrate potential for detecting which emulate PHQ-9...

Efforts to assess people's sentiments on Twitter have suggested that could be a valuable resource for studying political sentiment and it reflects the offline landscape. Many opinion mining systems tools provide users with attitudes toward products, people, or topics their attributes/aspects. However, although may appear simple, using analysis predict election results is difficult, since empirically challenging train successful model conduct tweet streams dynamic event such as an election....

Depression is a major public health concern in the U.S. and globally. While successful early identification treatment can lead to many positive behavioral outcomes, depression, remains undiagnosed, untreated or undertreated due several reasons, including denial of illness as well cultural social stigma. With ubiquity media platforms, millions people are now sharing their online persona by expressing thoughts, moods, emotions, even daily struggles with mental on media. Unlike traditional...

Microring resonators (MRRs) can be used to generate optical millimetre-wave solitons with a broadband frequency of 40–60 GHz. Non-linear light behaviours within MRRs, such as chaotic signals, logic codes (digital codes). The soliton signals multiplexed and modulated the using an orthogonal division multiplexing (OFDM) technique transmit data via network system. OFDM uses overlapping subcarriers without causing inter-carrier interference. It provides both high rate symbol duration over...

Purpose Many opinion-mining systems and tools have been developed to provide users with the attitudes of people toward entities their attributes or overall polarities documents. In addition, side effects are one critical measures used evaluate a patient’s opinion for particular drug. However, effect recognition is challenging task, since coincide disease symptoms lexically syntactically. The purpose this paper extract drug from reviews as an integral implicit-opinion words....

Representing world knowledge in a machine processable format is important as entities and their descriptions have fueled tremendous growth knowledge-rich information processing platforms, services, systems. Prominent applications of graphs include search engines (e.g., Google Search Microsoft Bing), email clients Gmail), intelligent personal assistants Now, Amazon Echo, Apple's Siri). In this paper, we present an approach that can summarize facts about collection by analyzing relatedness...

With the proliferation of social media over last decade, determining people's attitude with respect to a specific topic, document, interaction or events has fueled research interest in natural language processing and introduced new channel called sentiment emotion analysis. For instance, businesses routinely look develop systems automatically understand their customer conversations by identifying relevant content enhance marketing products managing reputations. Previous efforts assess on...

With the rapid growth of social media on web, emotional polarity computation has become a flourishing frontier in text mining community. However, it is challenging to understand latest trends and summarize state or general opinions about products due big diversity size data this creates need automated real time opinion extraction mining.
