Content-targeted advertising systems are becoming an increasingly important part of the funding for free web services. These programs automatically find relevant keywords on a web page, and then display ads based on those keywords. We propose a method for providing links to ads for travel products (which we call ad links) automatically. We extract keywords from citing areas of travel informatio...

In computer vision to create a knowledge base usable by information systems, we need a data structure facilitating the information access. Artificial intelligence community uses the ontologies to structure and represent the domain knowledge. This information structure can be used as a database of many geographic information systems (GIS) or information systems treating real objects for example ...

Traditional information systems return answers after a user submits a complete query. Users often feel “left in the dark” when they have limited knowledge about the underlying data, and have to use a tryand-see approach for finding information. A recent trend of supporting autocompletion in these systems is a first step towards solving this problem. In this paper, we study a new information-acc...

Collaborative tagging systems allow many users to add keywords (tags) to community-shared data items. Recently, collaborative tagging systems, also known as folksonomies, are growing on the web allowing people to annotate content, and then query by submitting keywords or tags. In this paper we define a Semantic Halo, as a set of additional information that can be provided from tagging systems t...

Information retrieval is one of the most important technologies at present. We can always get information in the Internet or distributed computing systems using various information retrieval models. For searching proper information that we need, it is necessary to construct efficient information retrieval agent systems helping many web clients’ requests. In this paper, we propose a simple new m...

The purpose of this study is to identify creative measures for information systems development. Content analysis was used as a methodology ,for analyzing key attributes to distinguish between creative and less creative IS applications. Twenty descriptions of information systems and the development process, published in Information d Management -an international academic journal -served as the s...

introduction: information technology might have some potential effects, such as influencing treatment process, rate and easiness of information retrieval, and information availability for making clinical decisions based on conditions and management, educational and research activities on health service systems. recognizing these effects can be concerned as a foundation to strategic planning in ...
