> library(ggplot2);
 search(); # what is in the environment
> old.packages(); # what is old?
> update.packages(); # update everything (carefully!)

Twitter is one of the most popular social networks through which millions of users share information and express views and opinions. The rapid growth of internet data is a driver for mining the huge amount of unstructured data that is generated to uncover insights from it. In the first part of this paper we explore different text mining tools. We collect tweets containing the “#MachineLearning” hashtag, prepare the data and run a series of diagnostics to mine the text that is contained in tweets. We also examine the issue of topic modeling that allows to estimate the similarity between documents in a larger corpus.

Ben has been doing data sciencey work since 1999 for organisations in the banking, retailing, health and education industries. He is currently on contracts with Pharmac and Aspire2025 (a Tobacco Control research collaboration) where, happily, he gets to use his data-wrangling powers for good. This presentation focuses on analysing text, with Tobacco Control as the context. Examples include monitoring mentions of NZ's smokefree goal by politicians and examining media uptake of BATNZ's Agree/Disagree PR campaign. It covers common obstacles during data extraction, cleaning and analysis, along with the key Python and R packages you can use to help clear them.

Information on the temporal interval of validity for facts described by RDF triples plays an important role in a large number of applications. Yet, most of the knowledge bases available on the Web of Data do not provide such information in an explicit manner. In this paper, we present a generic approach which addresses this drawback by inserting temporal information into knowledge bases. Our approach combines two types of information to associate RDF triples with time intervals. First, it relies on temporal information gathered from the document Web by an extension of the fact validation framework DeFacto. Second, it harnesses the time information contained in knowledge bases. This knowledge is combined within a three-step approach which comprises the steps matching, selection and merging. We evaluate our approach against a corpus of facts gathered from Yago2 by using DBpedia and Freebase as input and different parameter settings for the underlying algorithms. Our results suggest that we can detect temporal information for facts from DBpedia with an F-measure of up to 70%.

Big Data - these two words are heard so often nowadays. But what exactly is Big Data ? Can we, Pythonistas, enter the wonder world of Big Data ? The answer is definitely “Yes”. This talk is an introduction to the big data processing using Apache Hadoop and Python. We’ll talk about Apache Hadoop, it’s concepts, infrastructure and how one can use Python with it. We’ll compare the speed of Python jobs under different Python implementations, including CPython, PyPy and Jython and also discuss what Python libraries are available out there to work with Apache Hadoop.

n this talk, I will take the preparation of tutorial program in data science conference 2014 as an example and share some experience of R, Git, Github and CI(jenkins). The rating of our tutorial exceeds 4.2 (1 ~ 5). Some speakers and assistants agree that the assistant package "DSC2014Tutorial" improves the preparation and the teaching. Therefore, I would like to share the experience to establish such an working environment.

The PyConTW (http://tw.pycon.org) organizer wishes to improve the quality and quantity of the programming cummunities in Taiwan. Though Python is their core tool and methodology, they know it's worth to learn and communicate with wide-ranging communities. Understanding cultures and ecosystem of a language takes me about three to six months. This six-hour course wraps up what I - an experienced Java developer - have learned from Python ecosystem and the agenda of the past PyConTW. 你可以在以下鏈結找到中文內容： http://www.codedata.com.tw/python/python-tutorial-the-1st-class-1-preface

Homogenost preferencija (PH) predstavlja nužan i dovoljan uslov za reprezentaciju donosioca odluka sa stepenom funkcijom korisnosti pod Kumulativnom teorijom izgleda (CPT). Ukoliko ekvivalent u izvesnosti (CE) loza oblika (x, p; 0, 1-p) uzima vrednost CE, PH je zadovoljena ako CE loza (kx, p; 0, 1-p) uzima vrednost kCE. Ipak: pretpostavimo da je donosilac odluka spreman da prihvati siguran iznos od oko 2000 RSD za loz koji sa 50% donosi 4000 RSD; donosilac odluka bi možda prihvatio siguran iznos mnogo manji od 20 miliona RSD za loz koji sa 50% donosi 40 miliona RSD. U literaturi ne postoje direktni testovi PH već se o njenom važenju zaključuje posredno. U ovom radu predstavljamo dva direktna eksperimentalna testa PH. U Eksperimentu 1 (N=49) ispitanici su dali direktne numeričke ocene CE za 27 lozova oblika (x, p; 0, 1-p), gde je x varirano kao 100, 1000, 100000, 200, 2000, 200000, 500, 5000, i 500000 u RSD, a p kao 5%, 50%, i 90%. Vrednosti na lozovima su uvek bile umnošci osnovnih vrednosti x od 100, 200, i 500 RSD faktorima k = 10 i k = 1000 . Test PH koji smo razvili je semi-parametrijski i sastoji se od sledećih koraka. Prvo se na osnovu medijane CE lozova sa osnovnim vrednostima x određuju očekivane medijane za CE lozova koji nude vrednost x sa umnošcima k = 10 i k = 1000, na odgovarajućim nivoima verovatnoće dobitka: te vrednosti medijana su očekivane ukoliko je PH zadovoljena. Zatim se binomijalnim testom ispituje da li je raspodela CE ispitanika strogo iznad i strogo ispod očekivane medijane simetrična, i ukoliko nije, donosi se zaključak da PH nije zadovoljena. Intuitivno, ako se PH krši, očekuje se veća proporcija ispitanika ispod očekivane medijane. U devet od 18 binomijalnih testova PH nije bila zadovoljena na nivou p < .05; pored toga, dva puta je vrednost testa bila statistički marginalno značajna (p < .07). Svaki put kada je PH kršena, kršena je na očekivani način. U Eksperimentu 2 (N=37), koji je izveden po istom dizajnu sa nivoima p od 25%, 50%, i 75%, dobijeni su isti rezultati (devet kršenja PH na nivou p < .05, i dva marginalno značajna na p < .09 od kojih jedno u nepredviđenom pravcu). U Eksperimentu 2, sa faktorom k = 1000, svi ispitanici na svim lozovima krše PH u očekivanom pravcu. U 50% eksperimentalnih situacija u ovoj studiji PH nije bila zadovoljena; pri tom, njena kršenja su sistematske prirode i konzistentna sa intuicijom. Važenje PH ne predstavlja solidnu pretpostavku za izgradnju deskriptivne teorije odlučivanja. Ključne reči: kumulativna teorija izgleda, homogenost preferencija, rizik, stepena funkcija korisnosti.
