Abstract

Purpose

Open innovation communities are a growing trend across diverse industries because they provide opportunities of collaborating with customers and exploiting their knowledge effectively. Although open innovation communities can be strategic assets that can help firms innovate, firms nonetheless face the challenge of information overload incurred due to the characteristic of the community. The purpose of this paper is to mitigate the problem of information overload in an open innovation environment.

Design/methodology/approach

This study chose MyStarbucksIdea.com (MSI) as a target open innovation community in which customers share their ideas. The authors analyzed a large data set collected from MSI utilizing text mining techniques including TF-IDF and sentiment analysis, while considering both term and non-term features of the data set. Those features were used to develop classification models to calculate the adoption probability of each idea.

Findings

The results showed that term and non-term features play important roles in predicting the adoptability of ideas and the best classification accuracy was achieved by the hybrid classification models. In most cases, the precisions of classification models decreased as the number of recommendations increased, while the models’ recalls and F1s increased.

Originality/value

This research dealt with the problem of information overload in an open innovation context. A large amount of customer opinions from an innovation community were examined and a recommendation system to mitigate the problem was proposed. Using the proposed system, the firm can get recommendations for ideas that could be valuable for its business innovation in the idea generation phase, thereby resolving the information overload and enhancing the effectiveness of open innovation.

Abstract

Purpose

This study aims to examine university president's messages (PMs) on Korean university websites to analyze how Korean universities present their image and position themselves in the global marketplace.

Design/methodology/approach

Assuming that visions, missions and strategies might vary depending on the characteristics of a university, the study analyzed PMs according to university type: research, teaching and technology. The authors applied text analysis to 105 Korean universities' PMs to understand the images they project. The authors also used text mining on the PMs to examine the frequencies of keywords, to create word clouds, to investigate the keywords' degrees of centrality and to conduct sentiment analysis.

Findings

The findings show that Korean universities' PMs project hybrid images, simultaneously portraying the universities as public institutes that produce public goods and as globally competitive strategic actors. In addition, while Korean university PMs explicitly position the universities as education-oriented, they nonetheless reveal that the universities pursue both research-oriented and education-oriented goals.

Originality/value

This is the study to examine PMs using text mining with Python to extract information and reveal hidden meanings regarding how universities portray themselves on their websites. Highlighting current challenges faced by universities, this article argues for continued discussion on their societal roles and their strategies for positioning themselves in today's globalized and marketized higher education environment.
