Entity-oriented search deals with a wide variety of information needs, from displaying direct answers to interacting with services. In this work, we aim to understand what are prominent entity-oriented search intents and how they can be fulfilled. We develop a scheme of entity intent categories, and use them to annotate a sample of queries. Specifically, we annotate unique query refiners on the...

When referring to visually-present objects, an elementary site of language use, sometimes there isn’t enough information to resolve the speaker’s intended object. When this happens, more information needs to be elicited from the speaker. In this demo, we will show a simple system that uses the word-as-classifiers model to resolve referring expressions to objects, as well as a simple interaction...

Nowadays, new technologies allow him to make dreams came truth This paper describes the development process focused on the user, describing the many phases to follow to meeting user needs, and to ...

The increase of mobile and interconnected devices leads to the growth of demands for context aware applications. These applications deployed on top of pervasive environments must adapt themselves to context changes. Context aware applications have to continuously sense their physical environment, and adapt their behavior accordingly. These applications must perform four phases starting by colle...

‘Information need’ is a notion in IR that is ubiquitous, important, and intuitively clear. So far, surprisingly, the term seems to have defied formal definition. Of course, IR can continue to prosper without a formalization of ‘information need’. Yet when a field gets more mature there comes a time that frequently used notions should be formalized to make them susceptible of scrutiny. For IR su...

Targeting comprises defining the part of the business environment that corresponds to organizations’ strategic objectives and priorities. Targeting is not an easy process because it includes the interaction of managers who come from different organizational units that might have a fragmentary and blurred understanding of the overall issue.

Based on the results of a survey on user needs analysis and expe...

In this paper we explore the potential of combining the principle of polyrepresentation with document clustering. Our idea is discussed and evaluated for polyrepresentation of information needs as wells as for document-based polyrepresentation where bibliographic information is used as representation. The main idea is to present the user with the highly ranked polyrepresentative clusters to sup...
