Leo Mršić and Igor Kaluđer, IN2data, Zagreb: Customer Satisfaction Improvement using Advanced Analytics Models in Telco Industry 
Session will provide valuable insight into customer satisfaction improvement project which include  advanced analytics and models usage on massive data sample. Participants will learn how such model can be planed and delivered, how to plan KPI’s in such complex environment and how potential customer can prepare itself for such project. Authors will show several benefits which directly address business value improvement taken from real life experience in developing churn, churn & SNA and CLV models.

Andreas Hinz, LMU Munich: Where mathematics meets psychology
The Tower of Hanoi, invented by the French number theorist Edouard Lucas in 1883, is a classical example for recursion in mathematics and computer science. Early on, psychologists used the game for tests of cognitive abilities. The mathematical modelling as a Hanoi graph, allows for a computerized test tool which also includes a variant, called the Tower of London.

Ciril Petr, IMFM Ljubljana: Computational experiments on Hanoi graphs
Generalizing the classical Tower of Hanoi, invented by E. Lucas in 1883, to more than three pegs gives us a highly nontrivial mathematical object worth to explore not only analytically but also experimentally. The first significant computing experiment was published in 1999 by J.-P. Bode and A. M. Hinz who confirmed the Frame-Stewart conjecture in the case of four pegs for up to and including 17 discs. In 2004 R. Korf extended these results and also found a surprising phenomenon for n=15 discs in the corresponding Hanoi graph H_4^{15}. Even more surprising was that this Korf phenomenon did not occur for n=16 to 19, but reappeared for n=20 to 24. In 2014 we got access to supercomputing facilities where we managed to extend numerical results of several phenomena.

Blaž Rodič, Faculty of informations studies: Modelling of international migrant flows
We will present a project idea aiming to develop a model that will provide a better understanding of processes in migrant flows and enable identification of potential new phenomena in the dynamics of migration for researchers and stakeholders in the management of migration processes. Previous research in the field of migration has identified a number of rules and factors affecting individual decisions on migration and the choice of target countries. The model is to include the influence of conditions in countries of origin, transit and destination countries, the influence of geographic and political boundaries, the influence of migration and asylum policies in shaping migration routes and migration. The planned model will also serve as a good example of multi-method integration, which will encourage the development of multi-method simulation models in other problem areas.

Benedikt Perak and Tajana Ban Kirigin, University of Rijeka: Formalizing an Ontological Model of Lexical Concepts and Constructions for Emotion Domain
This paper describes the process of: modelling the ontological hierarchy of lexical units within emotion domain(s) as represented by Component Process Model (CPM) of Emotion and formalized by MFOEM ontology, and b) formalizing the semantic-syntactic properties of linguistic constructions used to construe the meanings of emotion domain(s) within large corpora hrWaC (1,3 GW). For the description of construal of the meaning we propose an Ontology Model of Lexical Concepts and Constructions (OMLCC). The OMLCC expresses the epistemological and ontological status of the concepts referenced by the lexical units. Nodes denote concepts. For a node x, A(x) denotes the (unique) superclass (4) – class (15) -subclass the concept denoted by x belongs to, and implicitly its entity from the ontology structure. Edges denote semantical connections of concepts, linking constructing concepts to the emerging concept from the next superclass in the hierarchical ontology structure.

Kristina Ban, Faculty of informations studies: Wikipedia growth across most prominent languages
Wikipedia is probably the largest existing global knowledge repository. As of October 2016 there are 284 languages with active Wikipedias, ranging from English with more than five billion articles to Wikipedias with only a single article. Wikipedias change and grow on daily basis, with growth reflecting the trends in cultures related to specific languages. We consider the dates of birth of all articles that simultaneously exist in 26 most prominent languages on Wikipedia. Our analysis reveals interesting growth patterns across languages: following the most prominent English, dynamics of other languages seems to be organized in clusters of languages that exhibit similar behavior.

Marko Potokar, Institute for IT forensics, Ljubljana: The admissibility of the use of ICT for control and security at the workplace
Viewing e-mails, programs for monitoring the use of work stations, use of GPS devices in company vehicles, activation of the GPS system on business mobile phones, viewing images and data of video surveillance cameras and access control system, use of DLP technology and biometric measures are only some of the possible solutions of modern information technology for the control and protection of resources of the organization. The fact is that we have to be careful in using IT solutions, which were designed in an environment where the attitude to privacy in the workplace is quite different than in Europe. In the US, namely information privacy in the workplace is less protected than in Europe. Legislative framework gives greater weight to the employer’s right to control their property, rather than the right of employees to privacy in the workplace. This raises a basic question: Is this kind of control admissible at all and what effect does it have on security and privacy of employees?

Tomaž Aljaž, Faculty of informations studies: Using Agile methodologies to increase throughput of projects
In IT, according to The Standish Group survey 2015 CHAOS report, only few projects perform well to meet cost, time, and scope. Only 16.2% software projects were completed on-time and on-budget, but provided approximately 42% of the originally-proposed features and functions. Clearly, the failure rate of IT projects is high and as response to that organisations tend to implement modern project management methodologies in terms of better project or business performance. The presentation shows example of using Agile methodologies to improve throughput of projects in multiproject environment with shared resources. In particular, it will be shown traditional approach of managing projects and continue with step-by-step approach using Agile project management methodologies, demonstrating how can be achieved the increased throughput at least doubling the number of projects that organisation can complete in the same period – all within existing employees and without changes in technology.
