Network Public Opinion

With the development of Internet, Network public opinion has been serving an import role in reflection of social public opinion. As there are a large number of websites and forums on the Internet, we need a powerful crawler system which can meet the demands of opinion mining. However, common crawler systems concern more about ranking and recommendation algorithms, which is less important in opinion mining. In this article, we introduced the design and implementation of a distributed crawler system for opinion mining. We also introduced some extra parameters such as keywords count and published time into the ranking and refreshing strategies. Experimental results demonstrate that the system can well support different sites, and the improved strategies can greatly enhance the crawling and monitoring efficiency.

Novel Approach

Due to the sudden and explosive increase in web technologies, huge quantity of user generated content is available online. The experiences of people and their opinions play an important role in the decision making process. Although facts provide the ease of searching information on a topic but retrieving opinions is still a crucial task. Many studies on opinion mining have to be undertaken efficiently in order to extract constructive opinionated information from these reviews. The present work focuses on the design and implementation of an Opinion Crawler which downloads the opinions from various sites thereby, ignoring rest of the web. Besides, it also detects web pages which frequently undergo updation by calculating the timestamp for its revisit in order to extract relevant opinions. The performance of the Opinion Crawler is justified by taking real data sets that prove to be much more accurate in terms of precision and recall quality attributes.

Purpose To provide an overview of communication characteristics exhibited by individuals with Angelman Syndrome (AS) and special considerations associated with the design and implementation of augmentative and alternative communication (AAC) programs. Method Results of recent studies exploring individuals' uses of AAC are reviewed, with particular emphasis on factors related to individuals' acceptance and successful uses of AAC systems. Results Not applicable Conclusion Despite their inconsistent access to practices previously found to foster individuals' acceptance of AAC systems, individuals with AS demonstrate the ability to use AAC systems, including high-tech AAC devices, successfully.
