Traditional approaches to rule-based information extraction (IE) have primarily been based on regular expression grammars. However, these grammar-based systems have difficulty scaling to large data sets and large numbers of rules. Inspired by traditional database research, we propose an algebraic approach to rule-based IE that addresses these scalability issues through query optimization. The operators...
Databases of text and text-annotated data constitute a significant fraction of the information available in electronic form. Searching and browsing are the typical ways that users locate items of interest in such databases. Faceted interfaces represent a new powerful paradigm that proved to be a successful complement to keyword searching. Thus far, the identification of the facets was either a manual...
MUSA is an acronym for "Historical-Archaeological Musem". It is a brand new Museum, realized by (and belonging) to the University of Salento (Lecce, Italy). MUSA has been conceived to enhance the services available for historical and archaeological didactical and research activities. In the exhibition of MUSA, we have made use of ICT, by means of the implementation of a Multimedial Expositive...
Time of statistic Web pages is going away. Nowadays every self-respecting service is trying to assure at least minimum of interactivity for website administration. One of the most important things in website creation is also simplicity in their later administration and actualization. For that purpose very useful are tools that manage the content on website and make administration easier.
This paper proposes a novel cyclic interface for browsing through a song database. The method, which sums multiple audio streams on a server and broadcasts only a single summed stream, allows the user to hear different parts of each audio stream by cycling through all available streams. Songs are summed into a single stream based on a combination of spectral entropy and local power of each song's...
This paper demonstrates a personal search agent system which enables the users to personalise their search and hence to save their time and effort. The system uses its own ranking algorithm and provides two types of search: a direct search (via a local database) and an indirect search (via third party search engines). The system achieves search personalisation through an initial user interaction that...
We introduce an architecture for unit tests that traces the values of output variables of JavaScript programming. We present an object model that describes the relationships between tracing and other programming components. We also present six types of tracing statements, implementation and automation approach. We created examples of XHTML and JavaScript programming to illustrate the implementation...
