Exploiting Language Models to Classify Events from Twitter
Vo, Duc-Thuan,Hai, Vo Thuan,Ock, Cheol-Young Hindawi Publishing Corporation 2015 Computational intelligence and neuroscience Vol.2015 No.-
<P>Classifying events is challenging in Twitter because tweets texts have a large amount of temporal data with a lot of noise and various kinds of topics. In this paper, we propose a method to classify events from Twitter. We firstly find the distinguishing terms between tweets in events and measure their similarities with learning language models such as ConceptNet and a latent Dirichlet allocation method for selectional preferences (LDA-SP), which have been widely studied based on large text corpora within computational linguistic relations. The relationship of term words in tweets will be discovered by checking them under each model. We then proposed a method to compute the similarity between tweets based on tweets' features including common term words and relationships among their distinguishing term words. It will be explicit and convenient for applying to k-nearest neighbor techniques for classification. We carefully applied experiments on the Edinburgh Twitter Corpus to show that our method achieves competitive results for classifying events.</P>

Recent free-space optical (FSO) communication tech nologies have demonstrated the feasibility of building WiFO, a highcapacity indoor wireless network using the femtocell architecture. In this paper, we introduce a cooperative transmission frameworkusing location assisted coding (LAC) technique to increase the over all wireless capacity. For a given network topology, LAC pro vides three different schemes with different coding/decoding pro cedures. Based on these schemes, achievable zero-error rate re gions for WiFO using LAC will be characterized. Both numericaland theoretical analyses are given to validate the proposed codingschemes.
STS 304 스테인리스강의 대기중 1050~1200˚C, 1시간 동안의 산화

The STS304 stainless steel was oxidized isothermally and cyclically at temperatures between 1050 and 1200˚C for 1 hr in air. During isothermal oxidation, it displayed good oxidation resistance at 1050˚C. However, it suffered from breakaway oxidation above 1100˚C, being accompanied with internal oxidation. During cyclic oxidation, it also displayed good oxidation resistance at 1050˚C, but it suffered from massive weight loss above 1125˚C. The oxide scales formed consisted primarily of Fe2O3, Fe3O4 with and without Cr2O3. They were generally non-adherent.
