The design of interactive experiences is increasingly important in our society. Examples include interactive media, computer games, and interactive portals. There is increasing interest in modes of interaction with virtual characters, as they represent a natural way for humans to interact. Creating such characters is a complex task, requiring both creative skills (to design personalities, emoti...

Darwin-FIRST, is an Artificial Intelligence procedure to automatically retrieve intelligence diluted in huge databases. FIRST stands for Full Information Retrieval System on Thesaurus, one expert system aided by agents and Darwin stands for Distributed Agents to Retrieve the Web Intelligence, a network of FIRST nodes. FIRST algorithms and agents extract from databases their inherent intelligent...

Generically system includes two types of categories, computerized based system and socio-technical system; the difference between both types of systems is that the socio-technical systems deals with technical operation and involves the users. Information system that deals with the flow of information regarding business and social perspective falls in socio-technical based system. ERP (Enterpris...

Web usage mining is an application of Web mining which focus on the extraction of useful information from usage data of severs logs. In order to improve the usability of a Web site so that users can more easily find and retrieve information they are looking for, we proposed a recommendation methodology based on correlation rules. A correlation rule is measured not only by its support and confid...

This paper reports the findings of a study into the behavior of the users of a mobile service. The study analyses the behavior of travelers using a Smartphone application to access real-time transit information and contrasts such user behavior with that of users accessing a transit information service from a website. Previous research in this field has tended to focus upon the perceived benefit...

We present a method to geometrize massive data sets from search engines query logs. For this purpose, a macrodynamic-like quantitative model of the Information Retrieval (IR) process is developed, whose paradigm is inspired by basic constructions of Einstein’s general relativity theory in which all IR objects are uniformly placed in a common Room. The Room has a structure similar to Einsteinian...

We investigate prediction and discovery of user desktop activities. The techniques we explore are unsupervised. In the first part of the paper, we show that efficient many-class learning can perform well for action prediction in the Unix domain, significantly improving over previously published results. This finding is promising for various human-computer interaction scenarios where rich predic...

Mobile technologies have enabled a new way of communicating, for whom mobile communications are part of normal daily interaction. This paper explores the proposed and verified Technology Acceptance Model (TAM) that can be employed to explain the acceptance of Mobile Learning (M-learning), an activity in which user‘s access learning material with their mobile device. 100 students from private an...

This study is based on the data from a survey of catalog use at three university libraries and one public library. Both “known-item” searches and “subject” searches were analyzed. The characteristics of the user population were examined and methodological problems of the survey were discussed. A relation was found between the academic rank of the catalog users and type of search that they carry...

regarding the highly intensive competition in the market, nowadays using customer-oriented strategies is necessary for retention and attraction of the costumers. nevertheless, using those kinds of strategies depends on understanding customer behavior patterns and classification of customers in accordance with those patterns. the current study aims to determine the strategies for dealing with ne...
