Abstract (sommario):

In less than a generation, the World Wide Web has grown from a relatively small cyber play-ground of academic "geeks" into an 11.5 billion-page collection of heterogeneous, inter-connected, network of information and collective knowledge. As an information environment the World Wide Web is informatically representative of all that is good and bad about the human need to both absorb and transmit knowledge. The 'open' nature of the Web makes instantly available to anyone who can "log-on", a boundless digital library of information, the quality of which cannot be enforced before, during, or even

Abstract (sommario):

Two experiments were conducted to determine the feasibility of providing online command-selection aids to novice users of an information retrieval system. The results of the first experiment revealed a difference in the mean and variability of search performance between novice and expert computer users. Half of the novices were performing much like experts, while the rest of the sample was extremely slow. These slower novices were using inefficient scrolling strategies and appeared to be unfamiliar with the structure of the database. The second experiment evaluated whether novices could be a

Abstract (sommario):

There has been a long history of studying library users and their information seeking behaviors and activities. Researchers developed models to better understand these information seeking behaviors and activities of users. Most of these models were developed before the onset of the Internet.

Abstract (sommario):

The rapid growth of the Internet and the advancements of the Web technologies have made it possible for users to have access to large amounts of on-line music data, including music acoustic signals, lyrics, style/mood labels, and user-assigned tags. The progress has made music listening more fun, but has raised an issue of how to organize this data, and more generally, how computer programs can assist users in their music experience. An important subject in computer-aided music listening is music retrieval, i.e., the issue of efficiently helping users in locating the music they are looking for

Abstract (sommario):

As the amount of computer mediated information (e.g., emails, documents, multi-media) we need to process grows, our need to rapidly sort, organize and store electronic information likewise increases. In order to store information effectively, we must find ways to sort through it and organize it in a manner that facilitates efficient retrieval. The instantaneous and emergent nature of communications across networks like Twitter makes them suitable for discussing events (e.g., natural disasters) that are amorphous and prone to rapid changes. It can be difficult for an individual human to filter

Abstract (sommario):

The theory of modern information retrieval processes must be improved to meet parallel growth and efficiency in its dependent hardware architectures. The growth in data sources facilitated by hardware improvements must be conversant with parallel growth at the user end of the information retrieval paradigm, encompassing both an increasing demand for data services and a widening user base. Contemporary sources refer to such growth as three dimensional, in reference to the expected and parallel growth in the key areas of hardware processing power, demand from current users of information service

Search goals of users of information retrieval systems have commonly been assumed to be static and well-formed. However, a significant amount of goal redefinition is detected in the studies described.

A challenging problem in the user profiling domain is to create profiles of users of retrieval systems. This problem even exacerbates in the multimedia domain. Due to the Semantic Gap, the difference between low-level data representation of videos and the higher concepts users associate with videos, it is not trivial to understand the content of multimedia documents and to find other documents that the users might be interested in. A promising approach to ease this problem is to set multimedia documents into their semantic contexts. The semantic context can lead to a better understanding of th

There are two classes of solution: general search engines, whether for the WWW or an Intranet, which make little use of specific domain knowledge or hand-crafted specialised systems which are costly to build and maintain.
