The importance of online review valence is a subject of debate among scholars. Prior studies mostly assumed valence as a “peripheral” cue derived from online review surface features (e.g., star ratings). This assumption has important implications as it restricts the negativity bias effects to a certain group of consumers who lack pertinent prior ex...

The large volume of contents on online review platforms can cognitively overload consumers. It’s therefore crucial for online review platforms to present information cues and features to help consumers make effective assessments of online reviews faster. Currently, major deficiencies in the design of major online review platforms hinder this object...

While negativity bias has been observed across many contexts, the consensus regarding its presence in the effects of electronic word of mouth (eWoM) reviews on consumers’ judgments is equivocal. Despite this equivocality, there has been a limited attempt to identify the conditions and the pertinent factors that alter the negativity bias in the effe...

Local governments are in an ideal position to integrate government, private, and citizen data to deliver beneficial new digitally enabled public services. However, progress towards achieving the benefits has stagnated in many cases. This is because managers lack the requisite know-how to lead the implementation and enactment of integrated enterpris...

Electronic word of mouth (eWoM) messages are increasingly consequential for consumers’ decisions regarding products/services. This has led to a large body of scholarly research on factors affecting eWoM message adoption. Adoption of an eWoM message refers to accepting the information and recommendations contained in an eWoM message, which consequen...

Case-based reasoning (CBR) supports ill-structured decision making by retrieving previous cases that are useful toward the solution of a new decision problem. The usefulness of previous cases is determined by assessing the similarity of a new case with the previous cases. In this paper, we present a modified form of the cosine matching function tha...

Case-Based Reasoning (CBR) systems support ill-structured decision making. In ill-structured decision environments, decision makers (DMs) differ in their problem solving approaches. As a result, CBR systems would be more useful if they were able to adapt to the idiosyncrasies of individual decision makers. Existing implementations of CBR systems ha...

A case-based reasoning (CBR) system supports decision makers when solving new decision problems (i.e., new cases) on the basis of past experience (i.e., previous cases). The effectiveness of a CBR system depends on its ability to retrieve useful previous cases. The usefulness of a previous case is determined by its similarity with the new case. Exi...

The objective of this study was to determine the impact on decision makers of two forms of computer support — suggestive guidance and informative guidance — on the problem formulation stage of judgmental tasks. Three hypotheses were postulated regarding the effectiveness of these two forms of guidance. The three hypotheses were tested in two experi...

Case-based reasoning (CBR) systems can support diagnosis of complex industrial systems. The success of a diagnostic CBR system depends on its ability to retrieve previous cases that provide information to solve a new case. To this end, the new case must be adequately described. However, to describe a new case in an ill-structured diagnostic decisio...

Evidence suggests that information centers (ICs) have significantly more interest in evaluating software packages and assisting in the selection of software packages than end users have. However, the selection of software packages by the information center product specialists (ICPSs) can compromise their usage. Ease of use and usefulness are believ...
