Logical Formalism

PICSEL is an information integration system over sources that are distributed and possibly heterogeneous. The approach which has been chosen in PICSEL is to define an information server as a knowledge-based mediator in which CARIN is used as the core logical formalism to represent both the domain of application and the contents of information sources relevant to that domain. In this paper, we describe the way the expressive power of the CARIN language is exploited in the PICSEL information integration system, while maintaining the decidability of query answering. We illustrate it on examples coming from the tourism domain, which is the first real case that we have to consider in PICSEL, in collaboration with the travel agency Degriftour. see

In this study, the change of farmer behaviour, which is thought to change slowly, over a 30 period, was evaluated in terms of information sources. In the study, the change in farmer attitudes with a longitudinal approach was designed in a process, and the data obtained from the same farmers and the same questionnaire forms were changed over time. A survey conducted in 1989 was repeated in the same region, in the same survey forms and in the same sample group (66 farmers) in 2019. In the analysis phase of the data obtained from the surveys, Multiple Compliance Analysis Technique was used. In the Polatlı District of Ankara Province, the long-term approach of 66 farmers, especially the changes in information sources and the non-logging habits of their businesses, has been determined with a longitudinal approach. The research results revealed that urban people have become close to rural areas and agriculture, and that their farmers have become close to district and provincial centres. As in all economic activities, research results support that the same jobs in agriculture for the long time do not have the opportunity to do the same and to be content with the knowledge left from the ancestor. This result is the most concrete indication that knowledge-based agriculture has become inevitable in every respect.

AbstractThrough the Internet and the World-Wide Web, a vast number of information sources has become available, which offer information on various subjects by different providers, often in heterogeneous formats. This calls for tools and methods for building an advanced information-processing infrastructure. One issue in this area is the selection of suitable information sources in query answering. In this paper, we present a knowledge-based approach to this problem, in the setting where one among a set of information sources (prototypically, data repositories) should be selected for evaluating a user query. We use extended logic programs (ELPs) to represent rich descriptions of the information sources, an underlying domain theory, and user queries in a formal query language (here, XML-QL, but other languages can be handled as well). Moreover, we use ELPs for declarative query analysis and generation of a query description. Central to our approach are declarativesource-selection programs, for which we define syntax and semantics. Due to the structured nature of the considered data items, the semantics of such programs must carefully respect implicit context information in source-selection rules, and furthermore combine it with possible user preferences. A prototype implementation of our approach has been realized exploiting the DLV KR system and its PLP front-end for prioritized ELPs. We describe a representative example involving specific movie databases, and report about experimental results.

Future Work

Nowadays, online news sources generate continuous streams of information that includes references to real locations. Linking these locations to coordinates in a map usually requires two steps involving the named entity: extraction and disambiguation. In past years, efforts have been devoted mainly to the first task. Approaches to location disambiguation include knowledge-based, map-based and data-driven methods. In this paper, we present a work in progress for location disambiguation in news documents that uses a vector-semantic representation learned from information sources that include events and geographic descriptions, in order to obtain a ranking for the possible locations. We will describe the proposed method and the results obtained so far, as well as ideas for future work.

Seeking Behavior

Objective – To describe critical care nurses’ on-duty information-seeking behavior. Design – Participatory action research using ethnographic methods. Setting – A twenty-bed critical care unit in a 275-bed community (non-teaching) hospital. Subjects – A purposive sample of six registered nurses (RNs) working shifts in the critical care unit. Methods – The researcher accompanied six RNs on various shifts (weekdays and weekends, day and night shifts) in the critical care unit and used participant observation and in-context interviews to record fifty hours of the subjects’ information-seeking behavior. Transcripts were written up and checked by the subjects for accuracy and validity. The resulting rich data was analyzed using open coding (concepts which emerged during data gathering, for example “nurse’s personal notes”); in vivo coding (participant-supplied concepts, for example “reading on duty”); and axial coding (hierarchical, researcher-developed concepts such as “information behaviors, information sources, information uses, and information kinds”) (147). Main results – The critical care nurses constantly sought information from people (patients, family members, other health care workers), patient records, monitors, and other computer systems and noticeboards, but very rarely from published sources such as books or online databases. Barriers to information acquisition included equipment failure, illegible handwriting, unavailable people, social protocols (for example physician – nurse interaction), difficult navigation of computer systems, and mistakes caused by simultaneously using multiple complex systems. Conclusion – Critical care nurses’ information behavior is strongly patient-centric. Knowledge-based information sources are rarely consulted on duty due to time constraints and the perception that this would take time away from patient care. In seeking to meet the knowledge-based information needs of this group, librarians should be wary of traditional, academic models of information delivery. Instead, they should consider a tailored ready reference service incorporating quality and quantity filtering.

Role Of Information

Introduction. The role of information institutions in the post-truth era is important in creating an independent and competent society in dealing with information. This conceptual article aims to see the role of information institutions in responding to community information behavior in the post-truth era. Data Collection Method. The method in this article uses a qualitative approach with the type of narrative review. Data Analysis. The analysis was carried out by synthesizing the literature and case studies from several reports discussing  the impact of fake news spread in the community. Results and Discussions. Information institutions need to take an active role in improving the conditions of society through knowledge-based development and information sharing processes, to create a community that is capable in using information and in evaluating the credibility and suitability of information sources. Conclusion. In the post-truth era, psychological aspects become an important aspect, where one's information behavior becomes more dominantly influenced by emotional dimensions and personal beliefs. This increasingly shows the importance of skills in evaluating information sources and critical thinking more clearly than in previous eras.
