This page shows the structure of the implemented ontology (anonymized for review). Use the search field on the left side to find potential filters (e.g., case study, survey), or use the buttons to navigate along the tree-structure. The count in parentheses indicates the number of articles that contain the respective term. This count is exclusively related to one term and does not cumulatively include terms on lower levels of the hierarchy.
Each term can be used as a semantic filter by clicking on it. We searched for all key terms contained in the implemented ontology in the text of all research articles in our database. Each term also contains multiple synonyms (e.g., plural, upper-case, similar terminology). For example, Clicking on "case study" will filter all articles in the search engine so that only articles are selected that contain the term "case study" or any of its synonyms. Clicking on the i-symbol for any term will lead to an overview of all synonyms.
In addition, we performed sentence classification. We only detect key terms that can be attributed to a focal article by classifying the sentences of an article. Consider the sentences: "We performed a case study", "Smith et al. (2022) performed a case study", and "A case study is a research method." Similar to the first example sentence, we only consider sentences that clearly describe a focal article. Therefore, we implemented a transformer-based sentence classification procedure (anonymized for review).
Semantic Filter Examples:
| Methods | Theories | Topics and Technologies |
|---|---|---|
| case study | theory of task technology fit | smart city |
| experiment | work systems theory | artificial intelligence |
| survey | representation theory | IT alignment |
