This thesis is focused on temporal information processing, which is a task framed in the field of natural language processing. The aim of this task is to obtain the temporal location and ordering of the events expressed in text or discourse, which requires the automatic interpretation of temporal expressions, events, and the temporal relations between them. The majority of current approaches are based on morphosyntactic knowledge. However, temporal entities are often ambiguous at that language analysis level. Our hypothesis is that the linguistic expression of time is a semantic phenomenon and therefore, to achieve a better extraction performance, temporal information must be processed using semantics. To prove this hypothesis, we present a semantic approach to temporal information processing: TIPSem. This is an automated system that includes features based on lexical semantics, semantic roles, and temporal semantics, in addition to morphosyntactic features. TIPSem has been empirically evaluated through the participation in the TempEval-2 international evaluation exercise and subsequent experiments based on this test. The results obtained firmly support the presented hypothesis and their analysis demonstrates that semantic features aid in handling morphosyntactic ambiguity and favour generalization capabilities. These conclusions have been reached for different languages (i.e., English, Spanish, Italian, and Chinese), which supports the defended hypothesis at a multilingual level. Finally, as compared with the state of the art, TIPSem obtains a very competitive performance level and introduces a remarkable improvement in event processing. TIPSem has been applied to the problem of graphical representation of temporal information. We have developed a dynamic interface which brings users time-based access to information: Time-Surfer. The results obtained through a user-oriented evaluation of this interface demonstrate that TIPSem's performance is also satisfactory from an extrinsic standpoint. ; This PhD thesis has been supported by the Spanish Government, in projects: TIN-2006-15265-C06-01, TIN-2009-13391-C04-01 and PROMETEO/2009/119, where Hector Llorens is funded under a FPI grant (BES-2007-16256).

L'experiment T2K, una col·laboració internacional on participen més de 500 físics de 12 països, ha detectat l'aparició de neutrins electrònics a partir d'un feix de neutrins muònics. És la primera vegada que s'observa aquest fenomen, conegut com a "oscil·lació", entre aquest tipus de neutrins, la qual cosa suposa un important pas per entendre millor aquesta partícula elemental. A més, aquesta detecció obre la porta a l'estudi experimental d'un dels principals misteris de l'Univers: el domini de la matèria enfront de l'antimatèria. En l'experiment participen investigadors de l'Institut de Física d'Altes Energies (IFAE, consorci Generalitat de Catalunya-Universitat Autònoma de Barcelona) i de l'Institut de Física Corpuscular (IFIC, CSIC-Universitat de València). ; El experimento T2K, una colaboración internacional donde participan más de 500 físicos de 12 países, ha detectado la aparición de neutrinos electrónicos a partir de un haz de neutrinos muónicos.

It is the first time researchers observe this phenomenon - known as "oscillation" - in these types of neutrinos. The discovery could represent an important step towards a clearer understanding of this elementary particle. Having detected the presence of these types of neutrinos opens the door to an experimental study of one of the greatest mysteries of the Universe: the power of matter over antimatter. The experiment includes participation of researchers from the Institute of High Energy Physics (IFAE, consortium formed by the Government of Catalonia-Universitat Autònoma de Barcelona) and from the Institute of Corpuscular Physics (IFIC, CSIC- Universitat de València).

Magistrsko delo obravnava problematiko poslovnih pogajanj v podjetju Metal Ravne, d.o.o., natančneje pogajanja med domačimi in ruskimi poslovnimi partnerji. Pogajanja so pomembna sestavina poslovnega delovanja in posebna dejavnost menedžerjev v organizacijah. So večsmeren proces sporazumevanja za usklajevanje interesov, v katerem več udeležencev vpliva medsebojno pri nastajanju skupnih odločitev. Dobra pogajanja morajo usklajevati interese in hkrati obvladovati nasprotja med udeleženci organizacije, ki so lahko notranji ali zunanji. Nasprotja v pogajanjih so gonilo napredka, usklajeni interesi kot rezultat pogajanj pa pogoj za uspešnost organizacije. Nasprotno pa se neusklajeni interesi lahko izrodijo v škodljive spore, ki nikomur ne koristijo. Dober pogajalec se ne rodi, ampak so dosego stopnje dobrega pogajalca potrebne večletne izkušnje. Izkušenost pa posledično prinese tudi izkušnje v načinu priprave za pogajanje, načinu komuniciranja in v pripravi strategije. Vse to je potrebno, saj zaradi vedno večjega odpiranja tujim trgom in povezovanja držav, poslovna pogajanja potekajo med pogajalci iz različnih kulturnih okolij, s specifičnim sistemom vrednot in pričakovanj. Te razlike v stališčih, prepričanju in percepciji so skupaj z mnogimi drugimi značilnostmi kulture temeljnega pomena za dobra mednarodna pogajanja in imajo velik vpliv na sam potek pogajanj. Poznavanje kulture nasprotne strani pomeni določeno prednost v pogajanjih, saj se z dobro pripravo na sama pogajanja skrajša čas pogajanj in hkrati pripomore k sklenitvi sporazuma, ki je za obe pogajalski strani najbolj zaželjen. Priprave na pogajanja s tujimi poslovnimi partnerji igrajo pomembno vlogo, kajti pri sami pripravi pogajanj izkušen pogajalec dobro spozna kulturo pogajalskega partnerja, strategijo pozna, stil, nebesedno komunikacijo in ostale dejavnike, ki vplivajo na potek in rezultat pogajanj. Neizkušeni pogajalci pogosto delajo omenjene napake, popolnoma ignorirajo kulturne razlike nasprotne strani itn. V magistrski nalogi smo želeli na konkretnem primeru pokazati, kakšne so razlike med slovenskimi in ruskimi pogajalci, kakšna je razlika v pogajalskem stilu in slogu, pogajalski strategiji, poslovnih običajih in poslovnem bontonu. Leta 2007 je namreč rusko podjetje KOKS postalo večinski lastnik Metala Ravne kot tudi večinski lastnik Slovenske industrije jekla. Kot večinski lastniki podjetja Metal Rusi odločajo o vlaganju v investicije. In prav to področje je temeljno pri pogajalski dejavnosti podjetja. Ob obravnavi problematike v podjetju Metal smo ugotovili, da so pogajanja podjetja Metal z ruskimi partnerji še v povojih. ; Master's thesis deals with the issue of business negotiations in the company Metal Ravne, d.o.o., concentrating on negotiations between the Slovenian and Russian business partners. Negotiations are an important element of business activity and a specific activity of managers in organisations. They are a multi-way process of communication for a coordination of different interests, in which several participants interact in the formation of joint decisions. Successful negotiations coordinate interests and manage conflicts between participants, which may be internal or external. Conflicts in negotiations are the driving power of progress while adjusted interests as a result of negotiations are the precondition for a successful organisation. On the other side, unadjusted interests may deteriorate into detrimental misunderstandings and disputes which is of no use to anyone. A negotiator is not born. It takes many years of experience to develop the skills necessary to become a successful negotiator. This eventually also brings experience in the way how we prepare ourseself best for negotiations, in the way how we communicate and how we prepare our strategy. All this is necessary as - due to an increasing opening of foreign markets and bonding among countries - business negotiations run between negotiatiors from a different cultural background, each with a specific system of values and expectations. These differences in attitudes, beliefs and perceptions, along with many other characteristics of culture, are essential for successful international negotiations and they have a major influence on the negotiation process itself. Knowing the culture of the opposite negotiating partner represents a certain advantage since good preparations for the negotiation itself reduce the time of negotiations, simultaneously contributing to the conclusion of the agreement most desired by both negotiating partners. Preparations for negotiations with foreign business partners play an important role since – already before negotiations - an experienced negotiator learns the culture of the opposite negotiating partner, his strategy, style, non-verbal communication and other factors which have influence on the course and on the outcome of negotiations. Inexperienced negotiators often make mistakes, completely ignoring cultural differences of the opposite partner and similar. This Master's thesis concentrates on revealing differences between the Slovenian and Russian negotiators, on differences in their negotiation style, strategies, business practices and business etiquette. In 2007, the Russian company KOKS became the majority owner of Metal Ravne, d.o.o. and also the majority owner of the Slovenian Steel Group, d.d. In this capacity, the Russians now make decisions on investments. And this is exactly the area which is essential in the negotiatiation business of the company. When analysing this issue in the company Metal Ravne, d.o.o., it was established that negotiations between Metal Ravne, d.o.o. and the Russian partners are still in the early stages of development
