The objective of personalized information retrieval systems is to infer the real user information need hidden behind his query, and then tailor the search results to this need. The user information need may be relative to one of the user’s multiple search contexts, such as user current location, user social context or an important event that occupies the public opinion of the user community. In this paper we present a new personalized information retrieval approach in which we design and use a user profile. This profile takes into account the different social, situational and temporal contexts of the user previous searches, and we introduced a personal semantics in the representation of these search contexts. The introduced personal semantics is interested by the identification and the valorization of the different cooccurrence relationships between the different relevant components of the user search history. The user profile, boasting its semantic vision, is used to infer the user current information need by the enrichment of the initial user query without going beyond the user current interest.

Modelling human behavior is important as it helps preparing for the situation of emergency to save lives. In this paper we present new methods to simulate crowd evacuation phenomena by using a physical model. We focus on applying more effective forces focusing on Spring-Force as general forces affecting agents as well as repulsive danger-force, in addition, we propose a new algorithm for an interaction behavior. We implement our algorithm in a real-world application which shows that our model provides results approaching reality and is promising compared to the other models.

According to its most popular definition, put forward by the now defunct Localisation Industry Standard Association (LISA), localisation in translation is the activity that involves making a product linguistically and culturally appropriate for a locale, that is, the target country and language in which the product in question will be used and sold (LISA, 2003). Localisation is part of the set of interdependent processes known by the acronym GILT: Globalisation, Internationalisation, Localisation and Translation (Cadieux and Esselink, 2002). If observed individually, translation can be defined as the process by which the meaning of a text written in a source language is communicated through an equivalent text in the target language. Internationalisation comprises the identification and isolation of all local information that appears in a product (for example, dates, numbers, currency or contact information) in order to make its localisation faster and simpler. Finally, globalisation combines the processes of internationalisation and localisation. It involves changes in the organisation of the business structure so that it is possible to serve any customer and offer them products or services regardless of their language, region or culture (Lommel, 2007). This definition of globalisation is more ABSTRACT: Diverse factors such as the development of globalisation processes and an ever-changing economic environment are encouraging companies to access external markets. Localisation, the activity that makes a certain product –for example, a website– linguistically and culturally appropriate for a particular country and language, is an extremely valuable tool for companies who want to pursue internationalisation strategies. In Spain, small and medium enterprises (SMEs) make up over 99% of the country’s business structure. However, the localisation of their websites is often deficient. An analysis of 70 Spanish SME corporate websites was performed with the purpose of assessing the degree and characteristics of website localisation in the SME sector in Spain. It was found out that the web presence of Spanish SMEs presents serious deficiencies and that the contents offered on their websites are often poorly localised, if at all. The information gathered enabled us to put forward a series of practical recommendations for SME corporate website localisation.
