The objective of this study was to identify the specialization profiles which are most required by companies and organizations in Lima, through the analysis of job postings published in the Internet. Text Mining techniques were used to extract relevant information and to identify some generic skills for the Peruvian statisticians. For purposes of this study, we analyzed 2,809 job postings publi...

Gender differences in Internet access and usage have been found in a number of previous investigations. The study reported here extends this work by providing an analysis of the impact of the Internet on men’s and women’s lives. A content analysis of 200 postings from men and 200 from women, on the topic of ‘‘Has the Internet changed your life’’ invited by a news website, was undertaken then ex...

We present a visualization for a message-board system, where postings are metaphorically represented by a plant. We focus on visualizing the different temporal aspects of the postings such as the length of time a message has been posted, the time between message postings and the rate at which a message is entered. The temporal analogy we use is the changing of colours we see in plants as the se...

We introduce PIHVI: a novel interactive system for visualizing and exploring a large hierarchical text corpus of online forum postings. The main view of the visual interface shows a largescale scatter plot, created by flexible nonlinear dimensionality reduction based on text contents of the postings, and we couple it with a coloring optimized by a second dimensionality reduction to represent th...

In this paper we describe our method for supporting artifact-centered communication. We elaborate a design space we have been elaborating called Tools That Tell Tales, and describe the TackTales prototype which provides an instance in this design space. We show how paper postings on a community pin board can be augmented to enable conversations around the physical, paper postings. The TackTales...
