Study of Context Modelling Criteria in Information Retrieval

Abstract

Abstract-Whereas the majority of works and research about context-awareness in ubiquitous computing provide context models that make use of context features in a particular application, one of the main challenges these last years has been to come out with prospective standardization of context models. As for Information Retrieval, the lack of consensual Context Models represents the biggest issue. In this paper, we investigate the importance of good context modelling to overcome some of the issues surrounding a search task. Thus, after identifying those issues and listing and categorizing the modelling requirements, the objective of our research is to find correlations between the appreciations of context quality criteria taking into account the user dimension. Likewise, the results of a previous survey about search habits have been used such that many socio-demographic categories were considered and the Kendall's W evaluation performed together with the Friedman test provided very interesting results that encourage the feasibility of building large scale context models.

Methods of Processing Context in Intelligent Systems

“…To date, the notion of context is used in linguistics, robotics, intellectual and mobile systems. At the same time, there is no common definition for the context for these industries [3]. Separate studies examine partial cases of the context or even their individual properties.…”

The Context of Operations as the basis for the Construction of Ontologies of Employment Processes

“…The knowledge got as a result of such analysis use in the systems of support making decision that will realize flexible, analytical and adaptive business processes [5]. At the same time, task of the use of knowledge and methods of analytic businessgeometry for support of the automated acceptance of decisions in operative activity of enterprise largely it remains unsolved.…”

Mining for Focus and Priorities in Donald Trump and Hillary Clinton’s Daily Tweets during the 2016 U.S. General Elections

“…Researchers do, indeed, recognize that the pervasiveness of mobile devices used for communication has had mixed effects on human behaviors ( [32], [33]). Therefore, the mining of information that occur regularly on computer networked is considered a very critical task that could provide useful information [34], especially if the context of each occurrence is well ascertained [35]. Data also show that the mining research over data stream has been prominent as they can be applied in many alternative areas in the real worlds [36].…”
